Host Affinity

Host affinity is configured at the instance level. It establishes a launch relationship between an instance and a Dedicated Host.
When affinity is set to Host, an instance launched onto a specific host always restarts on the same host if stopped. This applies to both targeted and untargeted launches.
When affinity is set to Default, and you stop and restart the instance, it can be restarted on any available host. However, it tries to launch back onto the last Dedicated Host on which it ran (on a best-effort basis).

AWS Application Discovery Service

Agentless discovery can be performed by deploying the Application Discovery Service Agentless Collector (Agentless Collector) (OVA file) through your VMware vCenter. After Agentless Collector is configured, it identifies virtual machines (VMs) and hosts associated with vCenter. Agentless Collector collects the following static configuration data: Server hostnames, IP addresses, MAC addresses, disk resource allocations, database engine versions, and database schemas. Additionally, it collects the utilization data for each VM and database providing the average and peak utilization for metrics such as CPU, RAM, and Disk I/O.

Agent-based discovery can be performed by deploying the AWS Application Discovery Agent on each of your VMs and physical servers. The agent installer is available for Windows and Linux operating systems. It collects static configuration data, detailed time-series system-performance information, inbound and outbound network connections, and processes that are running.
