Red Hat Ansible

  • Ansible is a very powerful open source automation language.
  • What makes it unique from other management tools, is that it is also a deployment and orchestration tool.
  • In many respects, it aims to provide large productivity gains to a wide variety of automation challenges.
  • While Ansible provides more productive drop-in replacements for many core capabilities in other automation solutions, it also seeks to solve other major IT challenges.
  • One of these challenges is to enable continuous integration and continuous deployment (CI/CD) with zero downtime.
  • This goal has often required extensive custom coding, working with multiple software packages, and lots of in-house-developed glue to achieve success.
  • Ansible provides all of these capabilities in one composition, being designed from the beginning to orchestrate exactly these types of scenarios.

WHY CI/CD (Continuous Integration/Continuous Delivery)?

  • Longer release cycles (“waterfall projects”) have dramatically higher overhead than more frequently released (“iterative” or “agile”) shorter cycles.
  • As a release begins, a quality assurance team is prepared, waiting for things to test, and IT does not have anything to deploy.
  • Towards the end of a release cycle, QA is running at full force, as is IT, but development is split between bugs and planning the next major release. Context switches are frequent.

Longer release cycles also mean a longer delay between the time when bugs are discovered and when they are addressed, which is especially a problem in large traffic web properties where single issues can affect millions of users.

To resolve this problem, the software development industry is rapidly moving towards “release early, release often,” under the banner of “Agile Software Development.”
