The Definition of DevOps“A set of processes, methods and systems forcommunication, collaboration and integrationbetween departments for Development(Applications/Software Engineering), TechnologyOperations and Quality Assurance (QA).” -Wikipedia, “DevOps”

The Definition of DevOps“A set of processes, methods and systems forcommunication, collaboration and integrationbetween departments for Development(Applications/Software Engineering), TechnologyOperations and Quality Assurance (QA).” -Wikipedia, “DevOps” ...okay, but what is DevOps?

DevOps From The Community

DevOps From The Community“So, the Devops movement is characterized by people with amultidisciplinary skill set - people who are comfortable withinfrastructure and configuration, but also happy to roll up their sleeves,write tests, debug, and ship features.”- Stephen Nelson-Smith, agilesysadmin.net

DevOps From The Community“So, the Devops movement is characterized by people with amultidisciplinary skill set - people who are comfortable withinfrastructure and configuration, but also happy to roll up their sleeves,write tests, debug, and ship features.”- Stephen Nelson-Smith, agilesysadmin.net“DevOps helps to enable IT alignment by aligning development andoperations roles and processes in the context of shared businessobjectives. Both development and operations need to understand thatthey are part of a unified business process.”-Damon Edwards, dev2ops.org

It is a framework ofideas and principles designed to foster cooperation, learning andcoordination between development and operational groups.”-James Turnbull, kartar.net

“If culture isnt the first part of explaining DevOps,youve missed the point.” - John Willis, DTO Solutions

This is not DevOps culture.

...nor is this...

...and DevOps culture is certainly not this!

Oh, and in the next 30 minutes or so?”

Gepetto: An IDE for Puppet

Cucumber-Puppet, BDD

Cucumber-Puppet, BDDFeature: General catalog policy In order to ensure applicability of a hosts catalog As a manifest developer I want all catalogs to obey some general rules Scenario Outline: Compile and verify catalog Given a node specified by "features/yaml/<hostname>.example.com.yaml" When I compile its catalog Then compilation should succeed And all resource dependencies should resolve Examples: | hostname | | localhost | Isn’t this awesome?* Yanked from: http://projects.puppetlabs.com/projects/cucumber-puppet/wiki
