By implementing a well-architected network using best design practices, and by selecting a capable cloud service provider, you can achieve high availability operations. You and the cloud provider share responsibility for achieving high availability for your applications running in the cloud.

The cloud provider must engineer its data centers for redundant power, cooling, and network systems, and create an architecture for rapid failover if a data center goes offline for whatever reason. As we discussed with computing, network, and storage pools, the cloud provider is responsible for ensuring high availability of these pools, which means that they're also responsible for ensuring redundancy of the physical components that compose these pools.

It's your responsibility as the cloud customer to engineer and deploy your applications with the appropriate levels of availability based on your requirements and budgetary constraints. This means using different regions and availability zones to eliminate any single point of failure. It also means taking advantage of load balancing and autoscaling to route around and recover from individual component failures, like an application server or database server going offline.
