Deployment automation allows applications to be deployed across the various environments used in the development process, as well as the final production environments. This results in more efficient, reliable, and predictable deployments. Solutions that automate your deployment processes improve the productivity of both the Dev and Ops teams and enable them and the business to develop faster, accomplish more, and ultimately build better software that is deployed more frequently and functions more reliably for the end-user.
Deployment automation is closely tied to release automation. An essential part of releasing a software product is deploying it, first on development environments, then on QA and UAT environments, and finally on the real production environment, either on the developing organization's premises, on a customer's premises or on the cloud. Deployment automation is a central part of modern Application Release Automation tools, and an important facilitator of accelerating software release cycles from months to weeks or even days, as dictated by the agile software development approach.
