A customized installation package (CIP) is a customized WebSphere® ESB installation image. An integrated installation package (IIP) is a larger package combining a stack of WebSphere software and even multiple CIPs. The IBM® WebSphere Installation Factory creates CIPs and IIPs.
Customers who need to install multiple installation packages in an automated and highly repeatable manner can create an IIP which aggregates those packages into a single installable package. As an example, you can have multiple servers on which you need to deploy WebSphere ESB and some number of feature packs. Instead of having to install each of these products as an independent step on each server, you can create an IIP that will install all of them at once.
The Installation Factory user specifies which installation packages to include in the IIP, the order in which they should be installed, and various other details about the desired behavior of the IIP and each of its contained installation packages.
Each product you include in the IIP can be customized separately for greater flexibility. For example, you could run the WebSphere ESB product install interactively and then run one or more feature pack installs silently to obtain a seamless install of the entire set of packages. There is also flexibility as to which contained installation packages actually get installed on any given invocation of the IIP; in other words you can choose not to install certain packages in the IIP.
One possible example of an IIP installation scenario is the following:
