2. Intro to DevOps

  • What is DevOps?
    • DevOps is a software engineering culture and practice that aims at unifying software development (Dev) and software operation (Ops).
    • DevOps is about a way of doing things not about the tools themselves.

It’s always easy to think of DevOps (or of any software industry paradigm) in terms of the tools you use; in particular, it’s very easy to think that if you use Chef or Puppet for automated configuration, Jenkins for continuous integration, and some cloud provider for on-demand server power, that you’re doing DevOps. But DevOps isn’t about tools; it’s about culture, and it extends far beyond the cubicles of developers and operators.

  • DevOps aims at shorter development cycles, increased deployment frequency, and more dependable releases, in close alignment with business objectives.
    • The point of implementing DevOps practices is about saving time, money, resources.
    • intimate understanding between the development and operations teams
  • Many DevOps initiatives focus all on automating everything. If someone has done it more than 1 time then automate it so it never has to be manually done again.
    • If we are spending all our time focusing on automating and implementing DevOps practices then the real product doesn’t launch or the real work doesn’t get done.
    • What does DevOps offer to WordPress development?
  • Increased Productivity – Developers, designers, and testers can work on solving new problems and not repeating the work needed to solve previous problems.
    • Environment – How do we establish environment standards that developers can work within and operations can easily support?
    • Repetitive Tasks – What work are developers or operations teams doing repetitively that make send to automate in some way that can be counted on and reliable?
    • Business Workflows – How can business processes and workflows be standardized?
  • Increased Quality – A team can rely on testable, reproducible, and quantitative results that can give a clear picture of the current product state.
    • Unit Tests – Requiring code that can be tested to fulfill requirements.
    • Standards – Code can be checked automatically against well define business or industry standards. (WordPress Coding Standards)
    • Business Requirements – Test and standards compliance reports can be automated to confirm business requirements are being met.
  • Reduced Time to Delivery of Releases – When standards and best practices are followed there are less mistakes and less changes required to prepare for a release.
    • Automated Tests – Tests can be run on changes or on regular business defined schedules.
    • On-Demand User Testing – Tests can be run by developers or quality control on-demand without spending time on setup.
    • More Releases – Small regularly scheduled, or planned, releases can be made on an as-needed basis.
