Looking at a sample Azure deployment for a mainframe workload
So, based on all of the technologies and services in Azure that we have outlined, what would a typical legacy workload look like? The age-old answer to this question is, of course, it depends. But some consistent patterns allow us to put together a good starting point for a prescriptive architecture. The following figure shows what a mainframe workload would look like in Azure:

These are often called Azure landing zones. There are a few things to point out about this architecture. First, as you can see, the production workload is made highly available within the Azure region by leveraging an application cluster that uses Redis Cache to keep the application servers in sync. This provides scalability and availability. With this type of implementation, more capacity can be added by adding an additional application server.
