6. All Things Continuous...
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

11. Implementing efficient build pipeline
● smaller jobs
● parallelism
● build promotion

12. 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
