A Rolling Deployment is a software release strategy where updates are gradually rolled out to a subset of servers or users instead of deploying the new version all at once. This approach minimizes downtime and allows for monitoring of the new version's performance in real-time. If issues arise, the deployment can be paused or rolled back without affecting all users. This method is commonly used in cloud environments and is part of modern practices like DevOps and Continuous Integration/Continuous Deployment (CI/CD). By using a rolling deployment, teams can ensure a smoother transition and maintain service availability while introducing new features or fixes.
