Deployment Matrix

Common Environment

Dev QA Ops

Why Developers Care

Build once and run anywhere:

  • A clean, secure and predictiable environment for apps
  • No worries about missing dependencies
  • Automate testing and packaging
  • Reduce/eliminate concerns about compatibility on different platforms

Why Operations Care

Configure once and run anything:

  • Make the entire lifecycle more efficient, consistent, and repeatable.
  • Eliminate inconsistencies between development, test, production, and customer environments.
  • Speed and reliability of continuous deployment and continuous integration systems.
  • Significant performance, lower costs, deployment, and portability (in comparision to VMs).
