Monitoring

Implement an automated performance testing strategy

System performance can degrade over time. It’s important to have an automated testing and monitoring system in place to identify degradation of performance. Every time you build target images based on new parent images, you should measure the performance impact of the changes in the parent image. This also includes the overall build process, because we have to make sure that a testing and monitoring system covers the CI/CD chain. Performance metrics and image sizes have to be collected using services like Amazon CloudWatch and teams must be alarmed if anomalies have been detected.
