What Is Devops?


What is DevOps?

DevOps creates trust between development and operations teams to increase deployment efficiency and reduce risk.

It’s a 4 step process: collaborate, validate, automate and iterate. In other words decide what you should have, validate that it is correct, automate it and then iterate.

Collaborate

  • Knowledge Capture: System knowledge from the entire IT team should be stored in one location to prevent misinformation.

  • Cross-Team: Team members need to be able to collaborate on system configurations to make the best use of subject matter experts.

  • Baseline: Define a reference architecture for your operating environment and baseline to create a 360 degree view of your infrastructure.

Validate

  • Quality Assurance: You should have continuous testing of your current state vs your desired state to prevent drift.

  • Audit/Compliance: Provide in depth audit and change information to satisfy audit and regulatory compliance needs.

  • Cross-Platform: DevOps is applicable to both legacy and modern systems.

Automate

  • Executable documentation: The documented system knowledge should be executable and serve as a configuration contract between teams.  You should only need to write it once and be able to execute it multiple times.

  • Best Practice Templates: Re-usable best practice templates should be created to speed up the automation process.

  • Process Integration: Contrary to the popular belief, DevOps actually complements existing processes and methodologies such as ITIL, Agile and CMMI.

Iterate

  • Reporting: Desired state configuration monitoring helps you to trace errors quickly. You should have a version controlled history of every test and configuration alongside performance metrics.

  • Environment Health: There should be detailed information on the health of application and infrastructure configurations of your internally managed or cloud hosted systems.

  • Improvement: Build on a well defined, validated baseline. There is no need to reinvent the wheel each time.
