Performance

  • Performance of creating/updating/deleting custom resources in the CloudFormation backend has been improved. #942
  • ECS Task Definitions are now cached in memory for improved emp ps performance. #902

Security

Features

  • Empire now contains expiremental support for using CloudFormation to provision resources for applications #814, #803.

  • Docker containers started by attached runs now have labels, cpu and memory constraints applied to them #809

Performance

  • emp ps should be significantly faster for services running a lot of processes #781
