Cloud Migration Services Consulting Services

Cloud migration involves transitioning applications, data, and workloads from one environment to another, whether moving from on-premise infrastructure to a cloud platform or switching between service providers. It is a time-bound project with a definitive cutover date, rather than a transactional purchase completed at the point of signing.

Scope of Coverage

• Inventory and Suitability Analysis: Identifying existing assets, mapping dependencies, and determining which components can be lifted as-is versus those requiring re-architecture for the new environment.
• Workload Transfer: Executing the migration of applications and data with validated rollback procedures in case the transition encounters issues.
• Strategic Re-architecture: Addressing known architectural weaknesses during the migration process to avoid carrying inefficiencies into the new environment.
• Cutover Execution: Performing the final switch, managing fallback strategies, and providing evidence of stability in the new environment before decommissioning the legacy system.

Common Pitfalls

• Persistence of Performance Issues: Migrating slow, costly, or fragile systems often results in the same limitations in the cloud, as the move changes location but not fundamental performance characteristics.
• Undetected Dependencies: Hidden reliance on local paths or legacy database versions can cause failures after the initial go-live, rather than immediately during cutover.
• Parallel Running Expenses: Maintaining both old and new environments during the transition incurs significant costs; an indefinite transition period turns into a recurring financial burden.

Key Decisions to Make Early

• Scope and Sequencing: Determining the priority order for workload migration, identifying items to defer, and establishing clear exit criteria for each stage.
• Cost Modeling: Forecasting the ongoing monthly costs of the new environment, including egress fees and idle capacity, rather than focusing solely on initial launch figures.
• Rollback Strategy: Defining which states are preserved, the duration of data retention, and the specific triggers that necessitate a return to the previous environment.
