Multi-AZ Deployments

Multi-AZ deployments involve hosting a system across multiple physical locations (availability zones) within a cloud provider’s infrastructure. This setup ensures high availability and disaster recovery by automatically replicating data and resources between zones. If one zone experiences an issue, the system seamlessly fails over to the other, minimizing downtime. It’s like having a backup system in a different building so your service remains continuous even if one location faces problems. This approach enhances reliability, performance, and data durability for applications and databases.
