Automated Release is the fully automated process of deploying a software service, including all the infrastructure it requires to run (excluding infrastructure dependencies like shared databases).
Re-deploying an existing service - meaning roll-out of a new version or roll-back to an old version - through and Automated Release must account for high availability, by use of fitting Release Strategies.
Side-effects of high frequency Automated Releases:
- Same way, every time, there are no surprises, if every release runs through the same, automated pipeline, doing the same stuff
- Reproducible state, as repeating a specific release (commit) yields the same results, results in the same state, rollbacks are easily possible
- Consistent environment, all stages (test, dev, prod, ..) are uniform, to the extend that true (integration / environmental) testing can be done
