vApps : Ensuring seamless application movement
and choice between clouds
• VMware vSphere™ includes support for vApp, a logical
entity comprising one or more virtual machines, which
uses the industry standard Open Virtualization Format to
specify and encapsulate all components of a multi-tier
application as well as the operational policies and service
levels associated with it.
• Just like the UPC bar code contains all information about
a product, the vApp gives application owners a standard
way to describe operational policies for an application
which the cloud OS can automatically interpret and
execute.
• vApps can comprise of any applications running on any
OS, and provide a mechanism for customers to move their
applications between internal clouds or external clouds
with still the same service levels.
