Cloud Native Applications

A container-ready application is also known as being cloud native and should abide by the guidelines in the The Twelve-Factor App.

All container-ready applications should minimally contain the following code instrumentations:

  1. Liveness checks
  2. Readiness checks
  3. Application metrics
  4. Centralised logging
  5. Distributed tracing
