Why WebBrain

Cloud Migration Services Company in Delhi, India

Cloud migration is fundamentally a business risk management exercise as much as a technical project. Poorly planned migrations result in downtime, data loss, cost overruns, and performance regressions. Well-planned migrations reduce infrastructure cost, improve reliability, and position the organization for future cloud native modernization.

Web Brain InfoTech delivers cloud migration services to clients in Delhi NCR, across India, and internationally, including the United States, United Kingdom, UAE, Canada, and Australia.

What Is Cloud Migration?

Cloud migration is the process of moving digital assets — applications, databases, workloads, and IT infrastructure — from on-premises servers or one cloud environment to another, typically to a public cloud platform such as AWS, Microsoft Azure, or Google Cloud Platform (GCP).

Infrastructure Migration

Moving servers, storage, and networking configurations to cloud equivalents

Application Migration

Moving software applications to run in cloud environments, with varying degrees of modification

Database Migration

Moving databases to cloud-managed database services with minimal downtime

Data Migration

Transferring existing data assets to cloud storage while maintaining integrity and accessibility

Legacy System Migration

Moving older, on-premises systems to modern cloud infrastructure, often requiring modernization alongside the move

Cloud-to-Cloud Migration

Moving workloads between cloud providers for cost, feature, or strategic reasons

Each migration type carries different technical approaches, risk profiles, and timeline expectations. Hybrid cloud transition — migrating select workloads to the cloud while maintaining others on-premises for compliance or latency reasons — is also a core area.

What Are the 6 R's of Cloud Migration?

The "6 R's" framework, popularized by AWS and widely adopted across the industry, categorizes the strategic approaches available for migrating any given application or workload to the cloud.

Strategy	Description
Rehost ("Lift and Shift")	Moving an application to the cloud with minimal or no code changes, typically by migrating virtual machines directly to cloud compute instances. Fastest migration approach, but captures the least cloud-native benefit.
Replatform ("Lift, Tinker, and Shift")	Making limited cloud optimizations during migration without changing the application's core architecture — for example, moving a database to a managed cloud database service while keeping the application logic unchanged.
Repurchase	Replacing an existing application with a cloud-based commercial alternative, typically a SaaS product, rather than migrating the existing system.
Refactor / Re-architect	Substantially redesigning the application to take full advantage of cloud native capabilities — containers, microservices, serverless — during the migration. Highest effort and cost, but captures the greatest long-term benefit.
Retire	Decommissioning applications that are no longer needed, reducing the overall migration scope and simplifying the target environment.
Retain	Keeping certain applications on-premises where migration doesn't provide sufficient benefit or where compliance, latency, or technical constraints prevent migration in the current planning cycle.

Most enterprise migrations apply a mix of these strategies across their application portfolio rather than a single approach uniformly.

What Are the Key Phases of a Cloud Migration Project?

A structured cloud migration follows a defined sequence of phases designed to reduce risk and maintain business continuity throughout the transition.

Phase 1: Assessment and Discovery

Cataloging existing applications, infrastructure, dependencies, and data. Assessing each application's migration complexity and assigning an appropriate 6 R's strategy.

Phase 2: Migration Strategy and Planning

Defining the target cloud architecture, migration sequence, timeline, and rollback plans. Establishing success criteria and identifying migration risks.

Phase 3: Cloud Environment Setup

Provisioning the target cloud environment, including networking (VPC configuration), security groups, identity and access management (IAM), and foundational infrastructure.

Phase 4: Pilot Migration

Migrating a low-risk, representative application first to validate the migration process, tooling, and target environment configuration before scaling to critical systems.

Phase 5: Data Migration

Moving databases and data assets using appropriate tools, often with continuous replication to minimize downtime during cutover.

Phase 6: Application Migration Execution

Migrating applications according to the defined sequence, using rehosting tools, containerization, or refactoring as appropriate for each workload.

Phase 7: Testing and Validation

Validating functionality, performance, security, and data integrity in the new environment before directing production traffic to it.

Phase 8: Cutover and Go-Live

Switching production traffic to the new cloud environment, typically using DNS cutover or traffic shifting strategies to minimize disruption.

Phase 9: Post-Migration Optimization

Right-sizing cloud resources, optimizing costs, and addressing any performance issues identified after go-live.

Got Questions?

Frequently Asked Questions

Straight answers about Cloud Migration Services.

Lift and shift (rehosting) moves an application to the cloud with minimal changes, providing a fast migration but limited cloud-native benefit. Refactoring substantially redesigns the application to use cloud native capabilities like containers and microservices, requiring more effort but delivering significantly better long-term scalability and cost efficiency.

Timelines vary widely based on scope. A single application lift-and-shift migration may take two to six weeks. A full data center migration for a mid-sized enterprise typically takes six to eighteen months, executed in planned migration waves.

Downtime can be minimized through strategies like continuous data replication, blue-green deployment, and DNS-based traffic cutover, though the achievable downtime window depends on the specific application architecture and database size.

The right provider depends on existing technology investments, specific service requirements, geographic data residency needs, and cost structure. Web Brain InfoTech provides independent assessment rather than defaulting to a single provider recommendation.

Not necessarily everything. The "Retain" strategy in the 6 R's framework acknowledges that some applications may be better kept on-premises due to compliance, latency, or cost factors, making a hybrid cloud approach appropriate for many organizations.

Cost estimation involves modeling target cloud infrastructure costs against current on-premises or existing cloud costs, factoring in migration project costs, potential downtime costs, and expected post-migration optimization savings from right-sizing and reserved capacity purchasing.

Yes. We provide post-migration optimization covering cost right-sizing, performance tuning, and ongoing cloud infrastructure management, with the option to continue toward cloud native modernization for applications that were initially rehosted.
