Ensuring high availability for cloud-based banking applications

It’s tempting to think that a cloud service provider will ensure the high availability of your critical cloud-based banking applications. The problem is that they really don’t.

Your cloud provider may have helped you configure a cluster of virtual machines (VMs) running out of multiple data centers or availability zones (AZs). It may have implemented an automated failover system to ensure that a standby VM in the configuration can take over immediately if the primary VM suddenly goes offline. It all sounds like it should deliver high availability, right?
