To plan, schedule, and control the build, test, and deployment of releases, and to deliver new functionality required by the business while protecting the integrity of existing services.

  • Major releases - such as new hardware, software, or introducing completely new functionality (e.g. v1.0, v2.0)
    • New routers
    • Transition from on-premises to cloud
  • Minor - improving existing functionality (e.g. v1.1, v1.2, v1.3)
    • Updating a driver
    • Flashing new firmware
  • Emergency - releasing a temporary fix in order to fix some urgent errors (e.g. v1.1.1, v1.1.2, v1.1.3)

How to Release

  • Big Bang Releases: Deployed to all users, all at once
  • Phased Approach Releases: Releases are more paced gradually
