Oracle Virtual Assembly Builder [From server-vrtualization-for-dummies]
Combined with Oracle VM, Oracle Virtual Assembly Builder helps organizations quickly create and configure entire multi-tier application topologies and provision
them onto virtualized resources. It enables IT organizations to take multi-tier enterprise applications —for example, a web server, application server, and database — and package them into self-contained, single-purpose virtual machines called software appliances.
Oracle Virtual Assembly Builder structures the process of combining these appliances into cohesive, reusable units known as assemblies.
Oracle Virtual Assembly Builder is a sophisticated development tool for introspecting the current application environment and creating assemblies
or collections of VMs, along with all their critical configuration parameters. This allows you to move your applications to a virtual environment, or to replicate easily and quickly within an existing environment.
An application “assembly” is very similar to an Oracle VM Template except that an additional set of configuration information and management policies are packaged along with the set of multiple virtual machines, their virtual disks, and the interconnectivity between them. These assemblies are packaged using the industry-standard Open Virtualization Format (OVF).
