|Eucalyptus Installation / Plan Your Installation|
This topic describes ways you can install Eucalyptus components on your machines.
You can install Eucalyptus in various ways. You can install the Cloud Controller, Walrus, CC, and SC on one machine, and an NC on one or more machines. Or you can install each component on an independent physical server. This gives each component maximal local resource usage.
Often your decision about how to distribute Eucalyptus components across an installation must trade deployment simplicity for performance or high-availability. For example, placing all cloud and cluster components on a single machine can simplify administration because there is only one machine to monitor and control for the Eucalyptus control services. However, each of the components deploys as an independent web service. If these components must share a single physical server, the physical resources that can be given to each service may become a performance bottleneck.
In general, the Eucalyptus components are designed to be run in any combination on the various physical servers in a data center.
