Rolling Application Updates

Rolling application updates are a method of updating a software application or service in production where only a portion of the system is taken down and updated at a time, rather than taking the entire system down for maintenance. This helps to minimize downtime and disruption to users and allows for a smoother and more controlled update process. The updated portion of the system is then put back into service, and the process is repeated for the next portion until the entire system has been updated. This method is commonly used for applications or services that require high availability and can minimize downtime and reduce the risk of service disruption.
