Devops
16 likes5,546 views
The document discusses the challenges between development and operations (dev and ops) teams, and introduces the concept of DevOps as a way to improve collaboration between the teams. It provides examples of tools like Puppet and Cucumber that can be used to automate infrastructure provisioning and application testing. The document emphasizes that DevOps is about processes, communication, and automation between devs and ops, not just the use of specific tools. It recommends several blogs and resources for further reading on DevOps.
