•Are you using licensed components? •Why are these ports open? •Why does it need so much resource? • This doesn’t seem very secure to me ……
•How do I scale this? • Someone else already built a container with

• Just relying on Containers has only shifted the burden of environment management from Ops to development
• The code cannot be delivered in an agile and consistent fashion - there is no single code base

Twelve Factors•One Codebase/Many
Deploys • Explicit Isolated
Dependencies •Config via Environment •Attached Backing Services • Separate Build/Release/Run • Stateless Processes
• Export Services via Port Bindings • Scale Out via Processes •Disposable Instances •Dev/Prod Parity • Logs == Event Streams •Admin Tasks == Processes
