Application

Test coverage

  • [ ] Is the test coverage 60% or higher?
    • In general, 60% is “acceptable”

Log

External monitoring

  • [ ] Is the stability of top page monitored by StatusCake?
    • Polling at least every 15 minutes

Vulnerability

  • [ ] Vulnerability diagnosis for externally released services.
    • Diagnostics by AWS inspector, IBM APP SCAN, etc. have been performed and the vulnerability has been fixed by the day of release

Load test

  • [ ] Has a load test been performed?

Infrastructure

Log (ex. CloudWatch)

  • [ ] Have you set how many days to retain logs?

Load Balancer (ex. ALB)

  • [ ] Is the response time monitored in NewRelic?
  • [ ] Is the load balancer 5xx monitored in NewRelic?

App/Batch Server (ex. EC2)

  • [ ] NewRelic's APMs are installed in your project.
  • [ ] CPU/memory/disk is monitored in NewRelic

Container Orchestrator (ex. ECS)

  • [ ] Check the hard limit of memory set in the task definition of ECS not to exceed the upper limit of the ECS instance memory.

Database (ex. RDS, ElastiCache)

Great list Kent!

Kindly permit me to add security.

Security
[] Is security built into the pipeline.
[] Where do you keep your images, hope they are not public?
[] Install git secrets so you wont commit secrets to repo.
