Software deployment is all of the activities that make a software system available for use.
Activities:
- Release
- Installation and activation
- Deactivation
- Uninstallation
- Update
- Version tracking
A rolling release is typically implemented using small and frequent updates. However, simply having updates does not automatically mean that a piece of software is using a rolling release cycle; for this, the philosophy of developers must be to work with one code branch as opposed to discrete versions. When the rolling release is employed as the development model, software updates are typically delivered to users by a package manager on the user's personal computer, accessing through the internet a remote software repository (often via a download mirror) stored on an internet file server.
