Application-release automation (ARA) refers to the process of packaging and deploying anapplication or update of an application from development, across various environments, and ultimately to production.^[1] ARA solutions must combine the capabilities of deployment automation, environment management and modeling, and release coordination.^[2]

ARA tools help cultivateDevOps best practices by providing a combination of automation, environment modeling and workflow-management capabilities. These practices help teams deliver software rapidly, reliably and responsibly. ARA tools achieve a key DevOps goal of implementingcontinuous delivery with a large quantity of releases quickly.^[3]

ARA is more than justsoftware-deployment automation – it deploys applications using structured release-automation techniques that allow for an increase in visibility for the whole team.^[4] It combines workload automation and release-management tools as they relate to release packages, as well as movement through different environments within the DevOps pipeline.^[5] ARA tools help regulate deployments, how environments are created and deployed, and how and when releases are deployed.^[6]

All ARA solutions must include capabilities in automation, environment modeling, and release coordination. Additionally, the solution must provide this functionality without reliance on other tools.^[7]
