amazon-cloudwatch-agent VS amazon-ssm-agent

cloudWatch - IAM Policy CloudWatchAgentServerPolicy for AWS Cloudwatch Agent.

Don't overlook SSM <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/session-...> which doesn't require sshd nor public access to get onto a machine and one can opt in to a bunch of audit logging if that's your jam. It's just a small bonus that one can also hop onto an instance from the AWS Console when using SSM, since it is websocket based and not "ssh from the browser"

The agent is Apache 2 if one wanted to build, enhance, or audit what it does: https://github.com/aws/amazon-ssm-agent#readme as is the local binary that awscli uses for the websocket handshaking: https://github.com/aws/session-manager-plugin#readme

There’s no toggle for it as RunShellScript is hard coded to use the sh shell in the agent source code. However you can modify your script to check if it’s running bash and if it’s not then re-execute with bash. See this feature request for a shell toggle, with example code. https://github.com/aws/amazon-ssm-agent/issues/46

Java tends to be the default language outside of specific use cases where other languages fit better, e.g. on-host agents like the SSM agent will be written in something like Go because it's compiled and hence easier to distribute. But server code typically is Java.
