You often hear the two titles of «DevOps» and «Immutable Infrastructure» used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for «DevOps.» He ended the session with some interesting case study examples.
