Medium Architecture

The medium architecture employs vertical clustering for CA Service Catalog and CA Service Accounting and horizontal clustering for CA Workflow.

The medium architecture can efficiently process a load of up to 10 catalog requests per minute. Both the CA Service Catalog and CA Workflow clusters require a load balancer (Server W0), which can be an existing instance.

The medium architecture includes one clustered server for CA Service Catalog and CA Service Accounting, one clustered server for CA Workflow, two load balancer servers, and the database server

Two servers, V1 and V2, exist in a vertical cluster, and reside on the same physical computer. Both V1 and V2 run CA Service Catalog and CA Service Accounting.

You install and cluster CA Process Automation according to the specifications in the CA Process Automation documentation. Alternatively, you install CA Workflow in a horizontal cluster on two servers, W1 and W2.

Two load balancers, V0 and W0, are the front ends to the Service View clusters and CA Process Automation clusters (or CA Workflow clusters), respectively.

Note: V0 and W0 can be the same computer.
