What is DevOps? @tracymiranda

DevOps is the new legacy @tracymiranda

Cloud Native Technologies • On demand self-service • Broad network access • Resource pooling • Rapid elasticity • Measured service

DORA State of DevOps Reports @tracymiranda

The Science of Lean Software and DevOps @tracymiranda

Building and scaling high performance technology organisations Throughput Stability Frequent deployments Fast mean time to recovery (MTTR) Low lead time from commit to deploy Low change failure rate @tracymiranda

Operation by pull request Git as the single place GitOps where we operate All changes are observable @tracymiranda

CONFIGURATION AS CODE

CONFIGURATION AS CODE WHAT IF … You can apply a sane change control practice to Jenkins configuration? Jenkins stops being a snowflake? You can safely roll back a failed upgrade? You could cookie cutter lots of identical Jenkins instances?

You can have fun tinkering

Or you can just get productive

Jenkins X Vision Figure out the best practice of how to CD cloud native apps Not just build and test, but review, promote, changelog, collaborate, etc. Integrate best of breed software in this ecosystem to achieve it Democratize it by building a pleasant CLI that represents high-level steps Be opinionated on how to do things Kubernetes is a means to the end

Best Practice We Preach Use cloud to develop, keep your Develop/collaborate changes in PR, laptop for what it needs to do review/test before merge Keep master always releasable Promote apps through multiple environments Deploy often and in small increments GitOps: deployment should be Inform other people about recorded and tracked in Git where changes are

Wrap-up

Conclusions • Configuration as code is a best practice to follow. • If you are using cloud native technologies, GitOps has essential techniques and practices to help you go faster without costing you stability. • There are some problems your tools won’t fix, for everything else there’s Jenkins X. @tracymiranda
