Planning for Vertical Scalability

Vertical scalability pertains to adding resources to individual server machines, for example, adding additional CPUs. Each machine is scaled to handle a certain load. In general, you might decide upon vertical scalability in your deployment because you have resource limitations or you are unable to purchase additional hardware as your deployment grows.

To vertically scale your deployment, you need to:

• Size each messaging component

  See Developing Messaging Server Architectural Strategies.

• Test the load of a prototype of your system

  See Using a Messaging Server Load Simulator.

• Monitor system performance and adjust the deployment accordingly
