A company will migrate its on-premises, self-managed Kubernetes cluster (hosting website containers) to Amazon EKS with managed node groups that use a fixed number of nodes. The on-premises PostgreSQL database will be migrated to Amazon RDS for PostgreSQL. A solutions architect must estimate the total cost of ownership (TCO) for the workload before migration. Which approach will provide the required TCO details?

Migration Evaluator (formerly TSO Logic) is designed specifically for TCO analysis of on-premises workloads migrating to AWS. It uses a collector to gather data from the existing environment, allowing for detailed cost comparisons and scenario modeling for services like EKS and RDS. The Quick Insights report provides the necessary TCO details. AWS DMS is for database migration, not TCO analysis. AWS Application Migration Service focuses on server migration and replication, not TCO. The AWS Cloud Economics Center provides general frameworks but does not generate specific TCO reports based on collected on-premises data.
