Cloud Migration Services Consulting Services

Cloud migration involves transitioning applications, data, and workloads from one environment to another, such as moving from on-premise servers to a cloud platform or switching between providers. This is a structured project with specific deadlines and a cutover phase, rather than a simple transaction that concludes at the point of purchase.

Scope of Coverage

• Inventory and Fit Assessment: Identifying existing components, mapping dependencies, and determining which items can be transferred as-is and which require re-architecting for the new environment.
• Workload Transfer: The actual migration of applications and data, accompanied by validated rollback procedures in case the transition fails.
• Strategic Re-architecture: Addressing known architectural weaknesses during the migration process to avoid carrying inefficiencies into the new environment.
• Cutover: The final switchover process, including fallback mechanisms and stability verification to ensure the new environment is reliable before decommissioning the old one.

Common Pitfalls

• Perpetuating Existing Issues: Moving a slow, costly, or unstable system to the cloud often results in the same performance issues, as the move changes location without resolving underlying performance problems.
• Undetected Dependencies: Relying on local file paths or legacy database versions can cause failures that surface after the initial migration, leading to unexpected disruptions.
• Extended Dual-Running Costs: Maintaining parallel environments during the transition incurs significant expenses; an unbounded transition period results in ongoing financial liability.

Key Decisions to Make Early

• Scope and Sequencing: Defining the migration order of workloads, identifying which can be deferred, and establishing clear exit criteria for each step.
• Cost Modeling: Understanding the recurring monthly costs of the new environment, including egress fees and idle capacity, beyond initial launch metrics.
• Rollback Strategy: Determining which states must be preserved, for how long, and what specific conditions will trigger a return to the previous environment.
