Only Build Your Binaries Once

• Reduce the risk of introducing difference on each build.
• Takes time to compile code (specially in large systems)

Deploy the Same Way to Every Environment

• Once you reach Production you are confident that your deployments work.

Smoke-Test your Deployments

• After deploying, immediately make sure that the most basic functionality works as expected.

Deploy into a copy of Production

• Make your environments a similar to production as pipeline. Again, to reduce the risk of ofintroducing bugs.

Each Change Should Propagate through the Pipeline Instantly

• Each checking should trigger the start of the build process.

If Any Part of the Pipeline Fails, Stop the Line

• Developers should make sure that their code didn’t break anything. If it does, they should fix it immediately.
