Daily Term: Zero-Downtime Deployment

Zero-Downtime Deployment

Zero-Downtime Deployment ensures a system remains available to users during updates, avoiding service interruptions. Techniques like blue-green deployments, rolling updates, or canary releases are used. For example, a web app might use a load balancer to redirect traffic to updated servers gradually. Zero-downtime deployment improves user experience and reliability, but it requires careful planning, redundancy, and compatibility between versions.
