DevOps Mind Map
In the last couple of years I’ve become very interested in the interactions and collaboration between development and operations teams, the ‘last mile’ of delivering working software into production, and keeping that software healthy and sustainable in production. I’ve had some satisfying experiences working in teams that have bridged part of the divide between development and ops… Continue reading
Enterprise Service Bust
When ESB advocates (or vendors) sell bus integration, they can make that diagram look so nicely clean and ordered – with nice square lines that never intersect. This appeals to the obsessive compulsive pointy haired boss types. The Enterprise Service Bus will guarantee to make your whiteboard diagram 42.4% less complex. Continue reading
Build Manifesto
I met a team in the recent past who were adopting automated testing. Developers would write some automated unit tests for their application code, and run them in the IDE before marking their work as complete. Testers would then write down the testing scripts for the completed software, and then manually execute those tests, recording results. An automation tester followed behind, writing automated functional tests from a growing backlog of completed manual tests… Continue reading
Whiteboard architecture – SEE???!!!

Continuous Integration – Ruthless Automation

My previous post talked about deployment repeatability primarily, but our goal is to improve the consistency of all processes that are repeated in the process of creating and maintaining system.
A sequence of actions performed manually multiple times is a surefire recipe for disaster… Continue reading
Continuous Integration – Repeatability
There’s some simple rules to follow to reduce the unexpected – particularly in build and deployment as part of a Continuous Integration process. If something works, I expect it to work again next time, and will put in place something to make sure it happens exactly the same next time. If something fails instead of just fixing it, I want to put something in place to make sure it never happens again. Simple application of these rules can bring calm and order. Continue reading
