Zero Downtime Deployment

Zero Downtime Deployment is a method of updating software or systems so that users experience no interruption or service outage during the update process. It involves carefully replacing or upgrading components while the system continues to run seamlessly. This approach ensures continuous availability, improves user experience, and reduces the risk of loss or disruption. Techniques like load balancing, rolling updates, and phased deployments are commonly used to achieve this, allowing updates to be applied without impacting ongoing operations or accessibility.
