Question

SAMUEL RUFUS · Accepted Answer

To ensure zero downtime during VM updates in Azure, you can use a combination of techniques like deploying VMs in an availability set or zone, using a load balancer with connection draining, and implementing health probes. You can also orchestrate updates by updating VMs one at a time using strategies like a rolling update, where you take one VM out of rotation, update it, and put it back in before moving to the next.
