Java application framework for use in a content delivery network (CDN)
First Claim
1. A method for processing requests to a given application executable in a distributed computing environment, wherein a set of edge servers are deployed in the distributed computing environment to offload processing from one or more origin servers, and wherein the given application has at least a first component and a second component, comprising:
- responsive to receipt of a request at a given edge server, determining whether the request is the first request for the given application;
if the request is the first request for the given application, retrieving the first component;
upon installation of the first component, or if the request is not the first request for the given application, executing the first component;
communicating with the origin server on an as needed basis to execute the second component; and
generating a response to the request based on the results of executing the first component and, as needed, the second component.

Abstract
An application deployment model for enterprise applications to enable 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.

10. A method for processing requests to a set of Java-based applications executable in a distributed computing environment, wherein a set of edge servers are deployed in the distributed computing environment to offload processing from a set of origin servers, and wherein each Java-based application has at least a first component, comprising:
-
deploying the first component of at least first and second Java applications on a given edge server having given application server code;
responsive to requests received at the given edge server, having the given application server code execute the first component of the first and second Java applications to generate responses to the requests. - View Dependent Claims (11, 12, 13, 14, 15, 16)

27. A method of executing Java applications operative in a content delivery network (CDN), the content delivery network comprising a distributed set of edge servers and a request routing mechanism for mapping client requests to the edge servers, wherein each application is a multi-tier Java application comprising at least first and second tiers, comprising:
-
deploying the first tier of each multi-tier application to a subset of the edge servers on an as-needed basis; and
in response to a given request, selectively executing the first tier of a given multi-tier application to respond to the given request. - View Dependent Claims (28)
