An application deployment model for enterprise applications to enable such
applications to be deployed to and executed from a globally distributed
computing platform, such as an Internet content delivery network (CDN).
According to the invention, application developers separate their Web
application into two layers: a highly distributed edge layer and a
centralized origin layer. In a representative embodiment, the edge layer
supports a servlet container that executes a Web tier, typically the
presentation layer of a given Java-based application. Where necessary,
the edge layer communicates with code running on an origin server to
respond to a given request. In an alternative embodiment, the edge layer
supports a more fully-provisioned application server that executes both
Web tier (e.g., presentation) and Enterprise tier application (e.g.,
business logic) components. In either case, the inventive framework
enables one or more different applications to be deployed to and executed
from the edge server on behalf of one or more respective entities.
