Enterprise Cloud Migration Services: How to Choose Between GSIs, AWS Programs, and Platform Tooling

Enterprise AWS migrations for large legacy portfolios are presented as requiring coordinated portfolio assessment, migration execution partners, AWS-native programs and tools, and a post-cutover operating platform. Assessment tools such as AWS Migration Evaluator, Application Discovery Service, and CAST Highlight can inform application-level decisions under the AWS 7 Rs, while global system integrators or AWS partners handle wave planning, remediation, testing, and cutover. AWS programs including MAP, Control Tower, Landing Zone Accelerator, MGN, and DMS may provide funding, governance foundations, and migration tooling, so their scope should be clarified before contracting external providers. The discussion emphasizes that compliance requires preventive landing-zone controls, deployment-time access and approval controls, and audit evidence, while warning that a blanket lift-and-shift approach can increase long-term costs. It argues that migration programs should also define a durable operating model for developer self-service, platform ownership, FinOps, and lifecycle management, proposing staged assessment, pilot, and scaling phases with measurable exit criteria. Qovery is positioned as a post-cutover internal developer platform that operates applications within a customer’s cloud account, rather than as a replacement for migration consultancies, assessment software, or AWS migration services.
