Addressable business Issues with Chef

•  Institutional Knowledge repository for IT •  Auditability ( compliance ) •  Repeatability & Deployment quality •  All changes in one place ( DRY ) •  Everything “breaks” or “works”, choose? •  Reduce random events & Variation •  Increase predictability •  Dynamic Scaling ( wide and deep ) •  Speed •  Feedback

Enterprise Current Practice

•  Applications delivered on CD/DVD/FTP •  50 page word install document •  15 page per patch word install document •  Hand written notes/email notes •  Requires developers on-site at initial install •  Human variability •  Upgrade fear and loathing – “it will break” •  Institutional knowledge loss ( key staff exit )

Welcome to the Coded Enterprise

•  Institutional Knowledge retained in a repository •  Code delivered to external VCS site •  Code compiled and deployed to test via Continuous integration •  Complete build on virgin VM's with supplier/Customer code, and Continuous

Integration/Continuous Deployment pipeline •  “One click” deploy gates to production, by business users ( Customers? ). Not

Ops/IT. •  Receive small incremental updates. No big-bang! •  Automated testing, reduced human testing

Coded Enterprise - “brave new world”

•  Auditable records of who, what, when, where and how •  Institutional Knowledge retained in central repository •  Limited console access ( End of the world? ) •  Version controlled deployments •  Tested deployment recipes. Tested Install iterations before a deployment recipe

is allowed to be used for a “live install” to development, test and subsequent production.

•  Decoupling of application deployment, and installation. Smooth process of deployment

•  Control the tool chain, cradle to grave

Continuous Delivery

Summary of business issues •  Institutional Knowledge retention •  Auditability ( compliance ) •  Customers conduct business ( not IT ) •  One change many replications •  Stability and Repeatability ( Feedback) •  Minimised Vendor lock-in •  Increased predictability •  Reduced time to market ( Speed) •  Dynamic Scalability – ( wide and deep )
