Continuous assessment and improvement
This stage of assessment focuses on two aspects:
Ongoing detailed application assessment, for each wave of applications
Continuous evolution and improvement of your portfolio
The first aspect, ongoing detailed application assessment, focuses on detailed discovery and analysis, down to the architecture and technology levels, to fully understand each application in a given wave, the proposed AWS design, and the migration strategy. This assessment of migration readiness is a prerequisite to starting a given migration wave.
The second aspect, continuous evolution and improvement of your portfolio, focuses on portfolio management and how you plan to improve applications over time, including the evolution and tracking of the business case.
The primary migration outcomes of this stage include the following:
Validated migration scope for each wave
A documented target architecture and migration strategy for applications in a given migration wave
Identified and validated migration patterns and tooling
Documented requirements (security, AWS infrastructure, and operations) and migration cut-over considerations for each wave
The primary optimization outcomes of this stage include the following:
Portfolio rationalization models and business outcomes
Proposed architecture and technology changes, and their expected benefits
Platform requirements (security, AWS infrastructure, and operations)
An implementation plan
