    What an IT Consultant Actually Does During a Major Systems Migration

    System migrations don’t fail because the tools were wrong. They fail when planning gaps go unnoticed, and operational details get overlooked. That’s where most of the risk lies, not in execution, but in the lack of structure leading up to it.

    If you’re working on a major system migration, you already know what’s at stake: missed deadlines, broken integrations, user downtime, and unexpected costs. What’s often unclear is what an IT consultant actually does to prevent those outcomes.

    This article breaks that down. It shows you what a skilled consultant handles before, during, and after migration, not just the technical steps, but how the entire process is scoped, sequenced, and stabilized. An experienced IT consulting firm brings that orchestration by offering more than technical support; it provides migration governance end-to-end.

    What a Systems Migration Actually Involves

    System migration is not simply relocating data from a source environment to a target environment. It is a multi-layered process with implications on infrastructure, applications, workflows, and in most scenarios, how entire teams function once migrated.

    System migration is fundamentally a process of replacing or upgrading the infrastructure of an organization’s digital environment. It may be migrating from legacy to contemporary systems, relocating workloads to the cloud, or combining several environments into one. Whatever the size, however, the process is not usually simple.

    Why? Because errors at this stage are expensive.

    • According to Bloor Research, 80% of ERP projects run into data migration issues.
    • Planning gaps often lead to overruns. Projects can exceed budgets by up to 30% and delay timelines by up to 41%.
    • In more severe cases, downtime during migration costs range from $137 to $9,000 per minute, depending on company size and system scale.

    That’s why companies do not merely require a service provider. They need an experienced IT consultancy that can translate technical migration into strategic, business-aligned decisions from the outset.

    A complete system migration will involve:

    “6 Key Phases of a System Migration”

    Key Phases of a System Migration

    • System audit and discovery — Determining what is being used, what is redundant, and what requires an upgrade.
    • Data mapping and validation — Satisfying that key data already exists, needs to be cleaned up, and is ready to be transferred without loss or corruption.
    • Infrastructure planning — Aligning the new systems against business objectives, user load, regulatory requirements, and performance requirements.
    • Application and integration alignment — Ensuring that current tools and processes are accommodated or modified for the new configuration.
    • Testing and rollback strategies — Minimizing service interruption by testing everything within controlled environments.
    • Cutover and support — Handling go-live transitions, reducing downtime, and having post-migration support available.

    Each of these stages carries its own risks. Without clarity, preparation, and skilled handling, even minor errors in the early phase can multiply into budget overruns, user disruption, or worse, permanent data loss.

    The Critical Role of an IT Consultant: Step by Step

    When system migration is on the cards, technical configuration isn’t everything. How the project is framed, monitored, and managed is what typically determines success.

    At SCS Tech, we own up to making that framework explicit from the beginning. We’re not just executioners. We remain clear through planning, coordination, testing, and transition, so the migration can proceed with reduced risk and improved decisions.

    Here, we’ve outlined how we work on large migrations, what we do, and why it’s important at every stage.

    Pre-Migration Assessment

    Prior to making any decisions, we first figure out what the world is like today. This is not a technical exercise. How systems are presently configured, where data resides, and how it transfers between tools, all of this has a direct impact on how a migration needs to be planned.

    We treat the pre-migration assessment as a diagnostic step. The goal is to uncover potential risks early, so we don’t run into them later during cutover or integration. We also use this stage to help our clients get internal clarity. That means identifying what’s critical, what’s outdated, and where the most dependency or downtime sensitivity exists.

    Here’s how we run this assessment in real projects:

    • First, we conduct a technical inventory. We list all current systems, how they’re connected, who owns them, and how they support your business processes. This step prevents surprises later. 
    • Next, we evaluate data readiness. We profile and validate sample datasets to check for accuracy, redundancy, and structure. Without clean data, downstream processes break. Industry research shows projects regularly go 30–41% over time or budget, partly due to poor data handling, and downtime can cost $137 to $9,000 per minute, depending on scale.
    • We also engage stakeholders early: IT, finance, and operations. Their insights help us identify critical systems and pain points that standard tools might miss. A capable IT consulting firm ensures these operational nuances are captured early, avoiding assumptions that often derail the migration later.

    By handling these details up front, we significantly reduce the risk of migration failure and build a clear roadmap for what comes next.

    Migration Planning

    Once the assessment is done, we shift focus to planning how the migration will actually happen. This is where strategy takes shape, not just in terms of timelines and tools, but in how we reduce risk while moving forward with confidence.

    1. Mapping Technical and Operational Dependencies

    Before we move anything, we need to know how systems interact, not just technically, but operationally. A database may connect cleanly to an application on paper, but in practice, it may serve multiple departments with different workflows. We review integration points, batch jobs, user schedules, and interlinked APIs to avoid breakage during cutover.

    Skipping this step is where most silent failures begin. Even if the migration seems successful, missing a hidden dependency can cause failures days or weeks later.

    2. Defining Clear Rollback Paths

    Every migration plan we create includes defined rollback procedures. This means if something doesn’t work as expected, we can restore the original state without creating downtime or data loss. The rollback approach depends on the architecture; sometimes it’s snapshot-based, and sometimes it involves temporary parallel systems.

    We also validate rollback logic during test runs, not after failure. This way, we’re not improvising under pressure.

    3. Choosing the Right Migration Method

    There are typically two approaches here:

    • Big bang: Moving everything at once. This works best when dependencies are minimal and downtime can be tightly controlled.
    • Phased: Moving parts of the system over time. This is better for complex setups where continuity is critical.

    We don’t make this decision in isolation. Our specialized IT consultancy team helps navigate these trade-offs more effectively by aligning the migration model with your operational exposure and tolerance for risk.

    Toolchain & Architecture Decisions

    Choosing the right tools and architecture shapes how smoothly the migration proceeds. We focus on precise, proven decisions, aligned with your systems and business needs.

    We assess your environment and recommend tools that reduce manual effort and risk. For server and VM migrations, options like Azure Migrate, AWS Migration Hub, or Carbonite Migrate are top choices. According to Cloudficient, using structured tools like these can cut manual work by around 40%. For database migrations, services like AWS DMS or Google Database Migration Service automate schema conversion and ensure consistency.

    We examine if your workloads integrate with cloud-native services, such as Azure Functions, AWS Lambda, RDS, or serverless platforms. Efficiency gain makes a difference in the post-migration phase, not just during the move itself.

    Unlike a generic vendor, a focused IT consulting firm selects tools based on system dynamics, not just brand familiarity or platform loyalty.

    Risk Mitigation & Failover Planning

    Every migration has risks. It’s our job at SCS Tech to reduce them from the start and embed safeguards upfront.

    • We begin by listing possible failure points, data corruption, system outages, and performance issues, and rate them by impact and likelihood. This structured risk identification is a core part of any mature information technology consulting engagement, ensuring real-world problems are anticipated, not theorized.
    • We set up backups, snapshots, or parallel environments based on business needs. Blusonic recommends pre-migration backups as essential for safe transitions. SCSTech configures failover systems for critical applications so we can restore service rapidly in case of errors.

    Team Coordination & Knowledge Transfer

    Teams across IT, operations, finance, and end users must stay aligned. 

    • We set a coordinated communication plan that covers status updates, cutover scheduling, and incident escalation.
    • We develop clear runbooks that define who does what during migration day. This removes ambiguity and stops “who’s responsible?” questions in the critical hours.
    • We set up shadow sessions so your team can observe cutover tasks firsthand, whether it’s data validation, DNS handoff, or system restart. This builds confidence and skills, avoiding post-migration dependency on external consultants.
    • After cutover, we schedule workshops covering:
    • System architecture changes
    • New platform controls and best practices
    • Troubleshooting guides and escalation paths

    These post-cutover workshops are one of the ways information technology consulting ensures your internal teams aren’t left with knowledge gaps after going live. By documenting these with your IT teams, we ensure knowledge is embedded before we step back.

    Testing & Post-Migration Stabilization

    A migration isn’t complete when systems go live. Stabilizing and validating the environment ensures everything functions as intended.

    • We test system performance under real-world conditions. Simulated workloads reveal bottlenecks that weren’t visible during planning.
    • We activate monitoring tools like Azure Monitor or AWS CloudWatch to track critical metrics, CPU, I/O, latency, and error rates. Initial stabilization typically takes 1–2 weeks, during which we calibrate thresholds and tune alerts.

    After stabilization, we conduct a review session. We check whether objectives, such as performance benchmarks, uptime goals, and cost limits, were met. We also recommend small-scale optimizations.

    Conclusion

    A successful migration of the system relies less on the tools and more on the way the process is designed upfront. Bad planning, lost dependencies, and poorly defined handoffs are what lead to overruns, downtime, and long-term disruption.

    It’s for this reason that the work of an IT consultant extends beyond execution. It entails converting technical complexity into simple decisions, unifying teams, and constructing the mitigations that ensure the migration remains stable at each point.

    This is what we do at SCS Tech. Our proactive IT consultancy doesn’t just react to migration problems; it preempts them with structured processes, stakeholder clarity, and tested fail-safes.

    We assist organizations through each stage from evaluation and design to testing and after-migration stabilization, without unnecessary overhead. Our process is based on system-level thinking and field-proven procedures that minimize risk, enhance clarity, and maintain operations while changes occur unobtrusively in the background.

    SCS Tech offers expert information technology consulting to scope the best approach, depending on your systems, timelines, and operational priorities.

  • The Future of Disaster Recovery: Leveraging Cloud Solutions for Business Continuity

    The Future of Disaster Recovery: Leveraging Cloud Solutions for Business Continuity

    Because “It Won’t Happen to Us” Is No Longer a Strategy

    Let’s face it—most businesses don’t think about disaster recovery until it’s already too late.

    A single ransomware attack, server crash, or regional outage can halt operations in seconds. And when that happens, the clock starts ticking on your company’s survival.

    According to FEMA, over 90% of businesses without a disaster recovery plan shut down within a year of a major disruption.

    That’s not just a stat—it’s a risk you can’t afford to ignore.

    Today’s threats are faster, more complex, and less predictable than ever. From ransomware attacks to cyclones, unpredictability is the new normal—despite advancements in methods to predict natural disasters, business continuity still hinges on how quickly systems recover.

    This article breaks down:

    • What’s broken in traditional DR
    • Why cloud solutions offer a smarter path forward
    • How to future-proof your business with a partner like SCS Tech India

    If you’re responsible for keeping your systems resilient, this is what you need to know—before the next disaster strikes.

    Why Traditional Disaster Recovery Fails Modern Businesses

    Even the best disaster prediction models can’t prevent outages. Whether it’s an unanticipated flood, power grid failure, or cyberattack, traditional DR struggles to recover systems in time.

    Disaster recovery used to mean racks of hardware, magnetic tapes, and periodic backup drills that were more hopeful than reliable. But that model was built for a slower world.

    Today, business moves faster than ever—and so do disasters.

    Here’s why traditional DR simply doesn’t keep up:

    • High CapEx, Low ROI: Hardware, licenses, and maintenance costs pile up, even when systems are idle 99% of the time.
    • Painfully Long Recovery Windows: When recovery takes hours or days, every minute of downtime costs real money. According to IDC, Indian enterprises lose up to ₹3.5 lakh per hour of IT downtime.
    • Single Point of Failure: On-prem infrastructure is vulnerable to floods, fire, and power loss. If your backup’s in the building—it’s going down with it.

    The Cloud DR Advantage: Real-Time, Real Resilience

    Cloud-based Disaster Recovery (Cloud DR) flips the traditional playbook. It decentralises your risk, shortens your downtime, and builds a smarter failover system that doesn’t collapse under pressure.

    Let’s dig into the core advantages, not just as bullet points—but as strategic pillars for modern businesses.

    1. No CapEx Drain — Shift to a Fully Utilized OPEX Model

    Capital-intensive. You pre-purchase backup servers, storage arrays, and co-location agreements that remain idle 95% of the time. Average CapEx for a traditional DR site in India? ₹15–25 lakhs upfront for a mid-sized enterprise (IDC, 2023).

    Everything is usage-based. Compute, storage, replication, failover—you pay for what you use. Platforms like AWS Elastic Disaster Recovery (AWS DRS) or Azure Site Recovery (ASR) offer DR as a service, fully managed, without owning any physical infrastructure.

    According to TechTarget (2022), organisations switching to cloud DR reported up to 64% cost reduction in year-one DR operations.

    2. Recovery Time (RTO) and Data Loss (RPO): Quantifiable, Testable, Guaranteed

    Forget ambiguous promises.

    With traditional DR:

    • Average RTO: 4–8 hours (often manual)
    • RPO: Last backup—can be 12 to 24 hours behind
    • Test frequency: Once a year (if ever), with high risk of false confidence

    With Cloud DR:

    • RTO: As low as <15 minutes, depending on setup (continuous replication vs. scheduled snapshots)
    • RPO: Often <5 minutes with real-time sync engines
    • Testing: Sandboxed testing environments allow monthly (or even weekly) drills without production downtime

    Zerto, a leading DRaaS provider, offers continuous journal-based replication with sub-10-second RPOs for virtualised workloads. Their DR drills do not affect live environments.

    Many regulated sectors (like BFSI in India) now require documented evidence of tested RTO/RPO per RBI/IRDAI guidelines.

    3. Geo-Redundancy and Compliance: Not Optional, Built-In

    Cloud DR replicates your workloads across availability zones or even continents—something traditional DR setups struggle with.

    Example Setup with AWS:

    • Production in Mumbai (ap-south-1)
    • DR in Singapore (ap-southeast-1)
    • Failover latency: 40–60 ms round-trip (acceptable for most critical workloads)

    Data Residency Considerations: India’s Personal Data Protection Bill (DPDP 2023) and sector-specific mandates (e.g., RBI Circular on IT Framework for NBFCs) require in-country failover for sensitive workloads. Cloud DR allows selective geo-redundancy—regulatory workloads stay in India, others failover globally.

    4. Built for Coexistence, Not Replacement

    You don’t need to migrate 100% to cloud. Cloud DR can plug into your current stack.

    Supported Workloads:

    • VMware, Hyper-V virtual machines
    • Physical servers (Windows/Linux)
    • Microsoft SQL, Oracle, SAP HANA
    • File servers and unstructured storage

    Tools like:

    • Azure Site Recovery: Supports agent-based and agentless options
    • AWS CloudEndure: Full image-based replication across OS types
    • Veeam Backup & Replication: Hybrid environments, integrates with on-prem NAS and S3-compatible storage

    Testing Environments: Cloud DR allows isolated recovery environments for DR testing—without interrupting live operations. This means CIOs can validate RPOs monthly, report it to auditors, and fix configuration drift proactively.

    What Is Cloud-Based Disaster Recovery (Cloud DR)?

    Cloud-based Disaster Recovery is a real-time, policy-driven replication and recovery framework—not a passive backup solution.

    Where traditional backup captures static snapshots of your data, Cloud DR replicates full workloads—including compute, storage, and network configurations—into a cloud-hosted recovery environment that can be activated instantly in the event of disruption.

    This is not just about storing data offsite. It’s about ensuring uninterrupted access to mission-critical systems through orchestrated failover, tested RTO/RPO thresholds, and continuous monitoring.

    Cloud DR enables:

    • Rapid restoration of systems without manual intervention
    • Continuity of business operations during infrastructure-level failures
    • Seamless experience for end users, with no visible downtime

    It delivers recovery with precision, speed, and verifiability—core requirements for compliance-heavy and customer-facing sectors.

    Architecture of a typical Cloud DR solution

     

    Types of Cloud DR Solutions

    Every cloud-based recovery solution is not created equal. Distinguishing between Backup-as-a-Service (BaaS) and Disaster Recovery-as-a-Service (DRaaS) is critical when evaluating protection for production workloads.

    1. Backup-as-a-Service (BaaS)

    • Offsite storage of files, databases, and VM snapshots
    • Lacks pre-configured compute or networking components
    • Recovery is manual and time-intensive
    • Suitable for non-time-sensitive, archival workloads

    Use cases: Email logs, compliance archives, shared file systems. BaaS is part of a data retention strategy, not a business continuity plan.

    2. Disaster Recovery-as-a-Service (DRaaS)

    • Full replication of production environments including OS, apps, data, and network settings
    • Automated failover and failback with predefined runbooks
    • SLA-backed RTOs and RPOs
    • Integrated monitoring, compliance tracking, and security features

    Use cases: Core applications, ERP, real-time databases, high-availability systems

    Providers like AWS Elastic Disaster Recovery, Azure Site Recovery, and Zerto deliver end-to-end DR capabilities that support both planned migrations and emergency failovers. These platforms aren’t limited to restoring data—they maintain operational continuity at an infrastructure scale.

    Steps to Transition to a Cloud-Based DR Strategy

    Transitioning to cloud DR is not a plug-and-play activity. It requires an integrated strategy, tailored architecture, and disciplined testing cadence. Below is a framework that aligns both IT and business priorities.

    1. Assess Current Infrastructure and Risk

      • Catalog workloads, VM specifications, data volumes, and interdependencies
      • Identify critical systems with zero-tolerance for downtime
      • Evaluate vulnerability points across hardware, power, and connectivity layers. Incorporate insights from early-warning tools or methods to predict natural disasters—such as flood zones, seismic zones, or storm-prone regions—into your risk model.
    • Conduct a Business Impact Analysis (BIA) to quantify recovery cost thresholds

    Without clear downtime impact data, recovery targets will be arbitrary—and likely insufficient.

    2. Define Business-Critical Applications

    • Segment workloads into tiers based on RTO/RPO sensitivity
    • Prioritize applications that generate direct revenue or enable operational throughput
    • Establish technical recovery objectives per workload category

    Focus DR investments on the 10–15% of systems where downtime equates to measurable business loss.

    3. Evaluate Cloud DR Providers

    Assess the technical depth and compliance coverage of each platform. Look beyond cost.

    Evaluation Checklist:

    • Does the platform support your hypervisor, OS, and database stack?
    • Are Indian data residency and sector-specific regulations addressed?
    • Can the provider deliver testable RTO/RPO metrics under simulated load?
    • Is sandboxed DR testing supported for non-intrusive validation?

    Providers should offer reference architectures, not generic templates.

    4. Create a Custom DR Plan

    • Define failover topology: cold, warm, or hot standby
    • Map DNS redirection, network access rules, and IP range failover strategy
    • Automate orchestration using Infrastructure-as-Code (IaC) for replicability
    • Document roles, SOPs, and escalation paths for DR execution

    A DR plan must be auditable, testable, and aligned with ongoing infrastructure updates.

    5. Run DR Drills and Simulations

    • Simulate both full and partial outage scenarios
    • Validate technical execution and team readiness under realistic conditions
    • Monitor deviation from expected RTOs and RPOs
    • Document outcomes and remediate configuration or process gaps

    Testing is not optional—it’s the only reliable way to validate DR readiness.

    6. Monitor, Test, and Update Continuously

    • Integrate DR health checks into your observability stack
    • Track replication lag, failover readiness, and configuration drift
    • Schedule periodic tests (monthly for critical systems, quarterly full-scale)
    • Adjust DR policies as infrastructure, compliance, or business needs evolve

    DR is not a static function. It must evolve with your technology landscape and risk profile.

    Don’t Wait for Disruption to Expose the Gaps

    The cost of downtime isn’t theoretical—it’s measurable, and immediate. While others recover in minutes, delayed action could cost you customers, compliance, and credibility.

    Take the next step:

    • Evaluate your current disaster recovery architecture
    • Identify failure points across compute, storage, and network layers
    • Define RTO/RPO metrics aligned with your most critical systems
    • Leverage AI-powered observability for predictive failure detection—not just for IT, but to integrate methods to predict natural disasters into your broader risk mitigation strategy.

    Need your business to thrive? Learn about key benefits of Data Analysis

    Today’s global marketplaces revolve on data, making sense of that data is essential to a company’s success. Failing to do so can result in a company falling behind.

    On its own, raw data doesn’t have much value. To leverage data to their advantage, businesses must apply data analytics, a discipline that systematically examines data in order to discover insights, patterns, and trends. Most businesses are aware of the potential rewards of investing in big data analytics, which promise to increase productivity, reduce costs, and improve decision-making. A recent survey by Micro Strategy found that businesses all across the world use their data for:

    • According to 90% of the business users who took part, their organization’s digital transformation strategies revolve around data and analytics
    • To increase their operations’ cost-effectiveness and process efficiency by up to 60%
    • 57% of businesses say they use data analytics to inform strategy and transformation
    • 52% of businesses use business analytics to track and enhance their financial performance

    What is Data Analysis?

    As a broad phrase, the processing of unstructured data to discover business insights is referred to as data analytics. It makes use of a variety of methods, procedures, statistics, and models. By definition, it is essentially a procedure for looking into raw data in order to derive significant insights. However, the development of AI and ML has caused the area of data analytics to advance at a rapid rate, reaching new heights.

    Usually, the purpose of data analytics is to give a business operational insights. This procedure entails reviewing historical data before applying the lessons discovered within to address the challenging business issues of the present.

    Despite the fact that big data analytics delivers value in a variety of ways, the following are some of its main advantages:

    • Quicker and wiser decision-making: businesses may quickly analyse massive amounts of data and come to wise judgements.
    • Cost savings: using big data technology, businesses can find better methods to conduct their operations and offer a cost-effective data storage solution.
    • A deeper comprehension of customer’s needs: big data reveals insights that assist businesses in identifying customer requirements and assessing satisfaction. This provides businesses with the knowledge they require to create long-lasting client relationships and provide higher-quality goods and services.

  • An introduction to Blockchain Technology and its potential uses

    An introduction to Blockchain Technology and its potential uses

    Even while blockchain technology is still in its nascent stages today, it is finding increasing use in important industries outside of the realm of digital currencies. Through the upkeep of immutable distributed ledgers in thousands of nodes, blockchain is the primary technology utilised to produce the digital currency, Bitcoin. The 21st century will see a huge impact from this disruptive technology on institutional operations, company operations, education, and our daily lives.  It has the power to alter the current Internet from “The Internet of Information Sharing” to “The Internet of Value Exchange.”

    Blockchain technology is anticipated to fundamentally alter how business, industry, and education operate while also accelerating the worldwide transition to a knowledge-based economy. This ground-breaking technology has numerous potential uses because of its immutability, transparency, and integrity for all transactions carried out in a blockchain network.

    The following structure illustrates a sample blockchain transaction flow. A peer-to-peer blockchain network is used by User A to start a transaction with User B. The network uses a cryptographic proof of identification (a set of public and private keys) to specifically identify users A and B. The transaction will then be published to the blockchain network’s memory pool while awaiting transaction validation and verification. Reaching consensus is the process of getting a predetermined number of approved nodes to create a new block. Following a consensus, a brand-new “block” is created across the entire blockchain network, and each node updates its individual copy of the blockchain ledger. All of the transactions that took place during this time are contained in this block.

    Advantages of blockchain technology

    Reliability: because blockchain networks are decentralised, the databases of all transaction records have changed from being closed, centralised ledgers maintained by a small number of recognised institutions to being open, distributed ledgers maintained by tens of thousands of nodes.

    Trust: blockchain network also decentralises trust. With organised ledgers, blockchain networks serve as new trust bearers. A group of tamper-proof nodes form a network that shares these ledgers.

    Security: the one-way hash function, a mathematical operation that transforms a variable-length input text into a fixed-length binary sequence, is used by the blockchain network. There is no obvious connection between the input and the output.

    Efficiency: every piece of data is automatically put through pre-defined processes. Blockchain technology can therefore both dramatically lower labour costs and increase productivity. Blockchain technology may hasten the clearing and settlement of some financial transactions, resulting in a quicker and more effective reconciliation procedure.

    Applications using blockchain technology

    • Blockchain offers a number of advantages in the financial and banking sectors in terms of improved record-keeping, security, and transparency. It makes it the ideal option for banking needs like fraud protection, client onboarding, and anti-money laundering.
    • By 2025, the worldwide blockchain market for healthcare is expected to reach $5.61 billion. Using blockchain technology could help resolve expensive and urgent issues in the healthcare sector. Such as inconsistent records, patient data loss or theft, banking information, and test results.
    • Blockchain can be a great solution for the insurance industry and aid in the reduction of underwriting, the identification of fraud, and the enhancement of cyber insurance plans. By 2023, the global insurance blockchain industry might reach $1.39 billion.
    • Businesses that spend a lot of money protecting themselves against breaches are also concerned about cyber security, not only SMEs. Blockchain system nodes automatically compare the data and warn any information that is falsified.
    • Blockchain technology is being used in education by some colleges and institutions, and the majority of them do so to support academic degree management and assumptive evaluation for learning outcomes.
    • Supply chain management can be challenging and involves a lot of data. Data storage using blockchain-based systems would guarantee quick access and strong security because altering the data would be impossible without reporting it as a result.
  • A complete guide on Cloud Computing

    A complete guide on Cloud Computing

    One of the technologies influencing how we work and play is cloud computing. The cloud helps businesses eliminate IT problems and promotes security, productivity, and efficiency. It also enables small enterprises to utilize cutting-edge computing technologies at a significantly lesser cost. Here is what you need to know about the cloud and how it can benefit your company.

    On-Demand Computing

    The term “cloud” describes online-accessible servers and software that anyone can use. You are spared from hosting and managing your hardware and software as a result. Additionally, it implies that you can use these systems from any location where you have internet access.

    Every day, you encounter cloud computing. You are accessing data that is kept on a server somewhere in the world whenever you check your Gmail inbox, look at a photo on your Dropbox account, or watch your favorite shows on Netflix. Even though the emails, videos, or other files you require are not physically present on your computer, you may quickly, simply, and affordably access them owing to contemporary cloud computing technology.

    Public, Private, and Hybrid Cloud

    Private, public, and hybrid deployment strategies are the three main types of cloud computing. In the end, all three models will give customers access to their business-critical documents and software from any location, at any time. It all depends on how they approach the task. The kind of cloud you should use for your company depends on several variables, including the purposes for which you intend to use it, applicable laws on data storage and transmission, and other aspects.

    Private Cloud

    A single entity is served via private clouds. While some companies construct and manage their ecosystems, others rely on service providers to do so. In either case, private clouds are expensive and hostile to the cloud’s advantages for the economy and IT labor productivity. Private clouds, however, are their sole choice because certain organizations are subject to greater data privacy and regulatory constraints than others.

    Public Cloud

    Distributed across the open internet, public clouds are hosted by cloud service providers. Customers can avoid having to buy, operate, and maintain their own IT infrastructure by using the most widely used and least-priced public clouds.

    Hybrid Cloud

    A hybrid cloud combines one or more public clouds with private clouds. Imagine you operate in a sector where data privacy laws are extremely rigorous. While you don’t want to host legally required data in the cloud, you do want to be able to access it there. To access data saved in your private cloud, you also want to deploy your CRM in the cloud. Using a hybrid cloud is the most sensible choice under these circumstances.

    Everything as a Service

    The cloud “stack” is made up of numerous levels. The collection of frameworks, tools and other elements that make up the infrastructure supporting cloud computing is referred to as a stack. Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) components are included in this. Customers that use these services have varied degrees of control and accountability over their cloud environment.

     

     

    Infrastructure as a Service

    The customer oversees managing everything with IaaS, including the OS, middle-ware, data, and applications. Other duties, including virtualization, servers, storage, and networking obligations, are handled by the service provider. Customers are charged by how many resources, including CPU cycles, memory, bandwidth, and others, they consume. Microsoft Azure and Amazon Web Services are two examples of IaaS products.

    Platform as a Service

    Customers can create, test, and host their applications using PaaS solutions. The consumer oversees managing their software and data; otherwise, the service provider takes care of everything. You don’t have to be concerned about operating systems, software upgrades, or storage requirements if you use PaaS solutions. Customers of PaaS pay for any computing resources they use. Google App Engine and SAP Cloud are a couple of examples of PaaS technologies.

    Software as a Service

    Customers acquire licenses to utilize an application hosted by the provider under the SaaS model. Customers often buy annual or monthly subscriptions per user instead of how much of a certain computer resource they consumed, unlike IaaS and PaaS models. Microsoft 365, Dropbox, and DocuSign are a few popular SaaS products. Small firms that lack the capital or IT resources to implement the most cutting-edge technologies would benefit greatly from SaaS solutions.

    Benefits of the Cloud

    Reduced IT costs: By using cloud computing services, recurrent costs for monitoring and maintaining an IT infrastructure can be greatly decreased.

    Scalability: When necessary, developers can increase storage and processing capability by using cloud services. Additionally, development teams do not have to spend time or money upgrading cloud computing services.

    Collaboration efficiency: For the agile technology sector, cooperation has always been a need. Professionals from all around the world may work and collaborate using current cloud services. With these functionalities, teams may communicate with clients or other teams online while collaborating in real-time and sharing resources.

    Flexibility: Cloud computing can provide a great deal of flexibility in addition to helping to lower operational costs. Developers and other key stakeholders now have easier access to crucial data metrics at any time and from any location.

    Automatic updates: Teams may use the most recent resources available while managing and meeting IT standards thanks to automatic updates. Cloud computing is a popular technology because it allows users to access the newest tools and resources without having to spend a fortune.

     

  • Data Migration: Process, Types, and Golden Rules to Follow

    Data Migration: Process, Types, and Golden Rules to Follow

    In our daily lives, moving information from one location to another is no more than a simple copy-and-paste operation. Everything gets far more complicated when it comes to transferring millions of data units into a new system.

    However, many companies treat even a massive data migration as a low-level, two-clicks task. Such an initial underestimation translates to spending extra time and money. Recent studies revealed that 55 percent of data migration projects went over budget and 62 percent appeared to be harder than expected or actually failed.

    How to avoid falling into the same trap? The answer lies in understanding the essentials of the data migration process, from its triggers to final phases.

    If you are already familiar with theoretical aspects of the problem, you may jump to the section Data Migration Process where we give practical recommendations. Otherwise, let’s start from the most basic question: What is data migration?

    What is data migration?

    In general terms, data migration is the transfer of the existing historical data to new storage, system, or file format. This process is not as simple as it may sound. It involves a lot of preparation and post-migration activities including planning, creating backups, quality testing, and validation of results. The migration ends only when the old system, database, or environment is shut down.

    Usually, data migration comes as a part of a larger project such as

    • legacy software modernization or replacement
    • the expansion of system and storage capacities,
    • the introduction of an additional system working alongside the existing application
    • the shift to a centralized database to eliminate data silos and achieve interoperability
    • moving IT infrastructure to the cloud, or
    • merger and acquisition (M&A) activities when IT landscapes must be consolidated into a single system.

    Data migration is sometimes confused with other processes involving massive data movements. Before we go any further, it’s important to clear up the differences between data migration, data integration, and data replication.

    Data migration vs data integration

    Unlike migration dealing with the company’s internal information, integration is about combining data from multiple sources outside and inside the company into a single view. It is an essential element of the data management strategy that enables connectivity between systems and gives access to the content across a wide array of subjects. Consolidated datasets are a prerequisite for accurate analysis, extracting business insights, and reporting.

    Data migration is a one-way journey that ends once all the information is transported to a target location. Integration, by contrast, can be a continuous process, that involves streaming real-time data and sharing information across systems.

    Data migration vs data replication

    In data migration, after the data is completely transferred to a new location, you eventually abandon the old system or database. In replication, you periodically transport data to a target location, without deleting or discarding its source. So, it has a starting point, but no defined completion time.

    Data replication can be a part of the data integration process. Also, it may turn into data migration — provided that the source storage is decommissioned.

    Now, we’ll discuss only data migration — a one-time and one-way process of moving to a new house, leaving an old one empty.

    Main types of data migration

    There are six commonly used types of data migration. However, this division is not strict. A particular case of the data transfer may belong, for example, to both database and cloud migration or involve application and database migration at the same time.

    Storage migration

    Storage migration occurs when a business acquires modern technologies discarding out-of-date equipment. This entails the transportation of data from one physical medium to another or from a physical to a virtual environment. Examples of such migrations are when you move data

    • from paper to digital documents
    • from hard disk drives (HDDs) to faster and more durable solid-state drives (SSDs), or
    • from mainframe computers to cloud storage.

    Database migration

    A database is not just a place to store data. It provides a structure to organize information in a specific way and is typically controlled via a database management system (DBMS).

    So, most of the time, database migration means

    • an upgrade to the latest version of DBMS (so-called homogeneous migration),
    • a switch to a new DBMS from a different provider — for example, from MySQL to PostgreSQL or from Oracle to MSSQL (so-called heterogeneous migration)

    The latter case is tougher than the former, especially if target and source databases support different data structures. It makes the task still more challenging when you have to move data from legacy databases — like Adabas, IMS, or IDMS.

    Application migration

    When a company changes an enterprise software vendor — for instance, a hotel implements a new property management system or a hospital replaces its legacy EHR system — this requires moving data from one computing environment to another. The key challenge here is that old and new infrastructures may have unique data models and work with different data formats.

    Data center migration

    A data center is a physical infrastructure used by organizations to keep their critical applications and data. Put more precisely, it’s the very dark room with servers, networks, switches, and other IT equipment. So, data center migration can mean different things: from relocation of existing computers and wires to other premises to moving all digital assets, including data and business applications to new servers and storages.

    Business process migration

    This type of migration is driven by mergers and acquisitions, business optimization, or reorganization to address competitive challenges or enter new markets. All these changes may require the transfer of business applications and databases with data on customers, products, and operations to the new environment.

    Cloud migration

    Cloud migration is a popular term that embraces all the above-mentioned cases, if they involve moving data from on-premises to the cloud or between different cloud environments. Gartner expects that by 2024 the cloud will attract over 45 percent of IT spending and dominate ever-growing numbers of IT decisions.

    Depending on volumes of data and differences between source and target locations, migration can take from some 30 minutes to months and even years. The complexity of the project and the cost of downtime will define how exactly to unwrap the process.

    Approaches to data migration

    Choosing the right approach to migration is the first step to ensure that the project will run smoothly, with no severe delays.

    Big bang data migration

    Advantages: less costly, less complex, takes less time, all changes happen once

    Disadvantages: a high risk of expensive failure, requires downtime

    In a big bang scenario, you move all data assets from source to target environment in one operation, within a relatively short time window.
