Installation process overview
The following figure shows the steps involved in installing components of a
system. The person taking these steps is usually a VM administrator.Installation process flowchart
Before downloading the distribution packages, the VM administrator must work with the product owner to determine which components, and how many instances of each component type, are needed, and where each instance will be put into service (for example, in which data center).
The distribution packages of some components have more than one descriptor file (as explained in Downloading-the-installation-files). Factors such as expected traffic volume and the number of concurrent pages and sessions help determine which descriptor file to use (see Sizing-considerations).
The VM administrator must certify the deployment environment by confirming that every host server satisfies the following requirements:
- The right virtualization software (product and version)
- The ability to support 64-bit guests
- Sufficient processor, memory, disk, and network-interface resources for guests and for the hypervisor
- Network connectivity from tapping points, between components, with storage devices, and to the internet
The VM administrator deploys the component instances and performs initial setup tasks. These tasks are handled in a setup "wizard" that runs when the virtual machine is first deployed.
When the deployment and initial configuration steps are complete, the VM administrator communicates logon credentials to the product owner and hands over control.
