What would be the proposed Proof of Concept (POC) plan for migrating 3DEXPERIENCE applications to AWS, including key milestones, resource requirements, and expected outcomes?

When migrating 3DEXPERIENCE applications to AWS, one must evaluate various migration strategies and resource choices, including traditional EC2 instances, containerization solutions, hybrid deployments, or serverless architectures. It is feasible to maintain essential applications like license servers and authentication servers on-premises while deploying components such as web servers, application servers, cache, storage, and RDS (Relational Database Service) on AWS.
