AWS Application Discovery Service collects both server and database configuration information. Server information includes hostnames, IP addresses, MAC addresses, as well as the resource allocation and utilization details of key resources such as CPU, network, memory, and disk. Collected database information includes the database engine identity, version, and edition. Once collected, this information can be used to size AWS resources as part of migration planning.
Application Discovery Service agents record inbound and outbound network activity for each server. This data can then be used to understand the dependencies across servers.
Application Discovery Service captures performance information about applications and processes by measuring host CPU, memory, and disk use, as well as disk and network performance (e.g., latency and throughput). This information allows you to establish a performance baseline to use as a comparison after you migrate to AWS.
Explore the data collected from your on-premises servers with Amazon Athena by running pre-defined queries to analyze the time-series system performance for each server, the type of processes that are running on them, and the network dependencies between different servers.
