A vApp is a container for virtual machines that offers resource controls and management for the virtual machines that are inside. Think of a vApp as a portable, self-contained box that holds multiple virtual machines that make up a multi-tiered application (like a web server, database, and security server), including all custom network configurations.
vApps offer:
- Container for multiple virtual machines
- Resource controls for the VMs inside the container
- Network configurations contained inside
- Portability of the vApp such that everything can be contained and transferred to another virtual infrastructure
- Entire vApps can be powered on, powered off, suspended, or shutdown
- Entire vApps can be cloned
