Cloud Migration Solutions Consulting Services

Cloud migration involves the transition of applications, data, and workloads from one environment to another, whether moving from on-premise infrastructure to a cloud platform or switching between different providers. This is a structured project with a defined timeline and cutover date, rather than a simple purchase that is completed upon signing a contract.

Scope of Coverage

• Inventory and suitability assessment: Identifying existing assets, understanding interdependencies, and determining which components can be migrated as-is and which require re-architecture for the new environment.
• Workload transition: The practical movement of applications and data, supported by a tested rollback strategy in case the migration encounters issues.
• Strategic re-architecture: Addressing known vulnerabilities during the transition to avoid carrying technical debt into the new environment.
• Cutover: The final switchover process, including fallback mechanisms and verification that the new environment is stable before decommissioning the legacy systems.

Typical Challenges

• Retaining existing inefficiencies: Simply moving a slow, costly, or fragile system to the cloud does not resolve those issues; the change of location does not automatically improve performance.
• Undisclosed dependencies: Critical failures often emerge after the initial go-live, such as jobs relying on local file paths or outdated database versions.
• Parallel operation expenses: Running both environments simultaneously during the transition incurs significant costs; an indefinite transition period results in ongoing financial expenditure.

Key Initial Decisions

• Scope and sequencing: Determining the order in which workloads are migrated, identifying any that should be deferred, and establishing specific exit criteria for each stage.
• Cost structure: Understanding the ongoing monthly costs of the new environment, including data egress and idle capacity, rather than focusing solely on initial launch figures.
• Rollback strategy: Defining what system state is preserved, the duration of preservation, and the specific triggers that would necessitate a return to the previous environment.
