How do I achieve zero-downtime deployments for Network overlays?

Achieve seamless network overlay deployments with zero downtime by utilizing strategies such as blue-green deployments, canary releases, and leveraging container orchestration tools. This approach minimizes service interruptions, enhances user experience, and ensures high availability during updates.

// Example of a basic blue-green deployment strategy for network overlays function deployNetworkOverlay(currentVersion, newVersion) { // Step 1: Create a new environment (Green) createEnvironment(newVersion); // Step 2: Migrate traffic gradually migrateTraffic(currentVersion, newVersion); // Step 3: Monitor performance if (checkPerformance(newVersion)) { // Step 4: Switch fully to new environment switchTraffic(newVersion); } else { // If performance issues arise, rollback to current version (Blue) rollbackTo(currentVersion); } }
