Migration and cost optimization

Move from assessing an existing application to choosing a migration path and evaluating the result. Cost guides are grouped separately from migration execution because resource usage, pricing, and organizational allocation are different decisions. Use the compute, storage, and data topics to continue into the services used by your chosen workload.

Assess and plan a migration

Start with the application portfolio and legacy-code assessment guides. Cost comparison, security, compliance, and workforce preparation add different perspectives to that plan; use them to identify questions before choosing implementation steps.

Modernize and verify a workload

Choose a container, serverless, content, or database migration guide that matches the source system. The post-migration benchmarking article then provides a separate path for investigating how the resulting workload performs.

Allocate and optimize cost

Begin with cost allocation when you need to explain where spending belongs, or use right sizing and lifecycle guides for a specific resource decision. Pricing references address the named service; they should be read in the context of the workload and account you are evaluating.
