AWS Application Discovery Service
AWS Application Discovery Service
AWS Application Discovery Service API collects on-prem server inventory and performance data — supports cloud migration planning (capacity assessment, dependency analysis).
Agentless or agent-based collection modes
Migration-planning phase only — not continuous monitoring
Download Application Discovery Agent and deploy to on-prem servers (VMware can use agentless). Data auto-ingests; analysis in Migration Hub.

About this API
Discovery Service is the starting point of AWS's migration-planning toolchain. Problem: enterprises migrating hundreds or thousands of on-prem servers from a datacenter to AWS first need an inventory — what runs on each server, CPU/memory utilization, network dependencies (A calls B, B depends on database C). Manual inventory is a nightmare. Discovery Service offers two collection modes: agent-based (install lightweight agent on each server for detailed metrics) and agentless (VMware vCenter mode, read via vCenter API). After 2-4 weeks of baseline collection, combined with Migration Hub, can estimate post-migration AWS instance types, monthly costs, which services must migrate together (tight dependencies). Essential pre-migration tool for enterprise lift-and-shift projects.

Strengths & limitations
Strengths
- Agentless or agent-based collection modes
- Auto-identifies CPU/memory/network usage baselines
- Captures complex dependencies to prevent post-migration outages
Limitations
- Migration-planning phase only — not continuous monitoring
- Limited support for niche platforms/virtualization (e.g. OpenStack)

FAQ
Is agentless mode accurate?+
For VMware environments, agentless accuracy is sufficient for migration planning. Physical servers or non-VMware virtualization must use agents.
