Cloud Migration Services Consulting Services

Cloud migration involves transferring 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 project defined by specific timelines and a cutover date, rather than an immediate purchase completed at the moment of signing.

Scope of Service

• Inventory and assessment: Identifying what currently exists, mapping dependencies, and determining which components can be transferred as-is and which require re-engineering for the new environment.
• Workload transfer: The actual movement of applications and data, accompanied by a validated rollback strategy in case the migration fails to hold.
• Targeted re-architecture: Addressing known weaknesses during the move to avoid perpetuating inefficiencies in the new environment.
• Cutover: The final switch, the execution of fallback procedures, and the verification that the new environment is stable before decommissioning the old one.

Common Pitfalls

• Perpetuating existing issues: Relocating a slow, costly, or fragile system to the cloud does not inherently improve it. The move changes the location, not the underlying performance or cost efficiency.
• Undetected dependencies: Components relying on local file paths or legacy database versions may cause failures after the initial go-live, rather than during it.
• Parallel running costs: Operating both environments simultaneously during the transition incurs significant expenses. An indefinite transition period results in ongoing, unnecessary costs.

Key Decisions to Make Early

• Scope and sequencing: Determining which workloads migrate first, which are deferred, and establishing clear exit criteria for each phase.
• Cost modelling: Understanding the monthly cost structure of the new environment, including egress charges and idle capacity, rather than focusing solely on initial launch figures.
• Rollback strategy: Defining what state is preserved, for how long, and the specific triggers that would necessitate a return to the legacy environment.
