All Things Continuous...


Continuous Integration (CI):

What is it?



Continuous Integration (CI):

Coined by Kent Beck as part of eXtreme Programming.

● integrate work frequently into mainline● multiple integrations per day● integration verified by automated tests● results in subsequent build● detect integration errors early!● results in cohesive software more rapidly

-Martin Fowlerhttp://martinfowler.com/articles/continuousIntegration.html

Continuous Deployment:

"...is actually deploying every change into production, every day or more frequently."

-Martin Fowler

Continuous Delivery:

"...is about keeping your application in a statewhere it is always able to deploy into production."

-Martin Fowler



The Deployment Pipeline


The Deployment Pipeline


DEV

Integ.

Staging

PROD

build, test, analyse,...

● smaller jobs● parallelism● build promotion

Implementing efficient build pipeline

The Quest


● PaaS not IaaS● Groovy & Grails support● Robust Developer Tooling● Hosted Continuous Integration (CI) solution● Support for Continuous Deployment● Cloud based● Holistic Solution● Runtime monitoring and tooling

The Matrix
