Rolling update in the sense, update the existing version of an Application, Operating system etc, without interrupting the running systems.
Most of the LINUX distribution are consisted of the rolling updated and rolling releases, they would be able to attend the updating process while running. So the users and developers are served by best patches and updates for the existing systems.
This rolling updates used several methodologies for updates the systems. one is deliver frequent small updates and patches, as an example arch LINUX would be taken. Another one is replace the old image of the operating system with the new changes, the changes are added to the updating process. The Ubuntu cover versions is an example for this.
Benefits of using Rolling updates and releases.
- Easy to maintain the enterprise level servers and datacenter and clouds with the rolling releases and updates.
- Automatically software applications and servers are get updated without any interruption.
- Does not take too long time to upgrade to major releases as the fixed releases. Because the system updates frequently.
And there also a major disadvantage of having rolling updates, because if there is a bug in a update or new release that would be directly affected to the entire system.
But according to the review and experience most of the IT industries uses the rolling update supported systems.
