AWS Migration Hub
Central dashboard to track application migrations from on-premises to AWS across multiple AWS services (like AWS Application Migration Service, Database Migration Service, etc.). Think of it as your migration “command center.”
AWS Application Discovery Service
Discovers and collects data about your on-premises servers to plan migrations.
Two discovery options:
- AWS Discovery Agent - Lightweight agent installed on VMs/servers to collect detailed system info (CPU, memory, network, processes)
- AWS Agentless Discovery Connector - OVA appliance deployed in VMware to collect VM inventory without installing agents
Migration Evaluator (formerly TSO Logic)
