Dynamic deployment of services in a computing network

Abstract

Methods, systems, and computer program products for improving network operations by dynamically deploying services (such as web services or other network-accessible services) in a computing network. A process is defined whereby conditions such as usage metrics for incoming client requests (or other network conditions such as load balancing considerations) are monitored, and used to trigger dynamic deployment of web services to locations in the network in order to improve efficiency (e.g. by reducing response time to the client and/or reducing the burden on the back-end computing system resources). Service requests are dynamically routed to the destination where the service resides, in a manner which is transparent to the client. In an optional aspect, programmatic replication of system upgrades may be implemented by redeploying services using this same dynamic deployment approach, enabling the complexity of upgrading previously-deployed software to be reduced significantly. As another optional aspect, previously-deployed software may also be automatically and programmatically undeployed using disclosed techniques.

RELATED INVENTIONS[0001] The present invention is related to U.S. Pat. No. ______ (Ser. No. ______), which is titled "Dynamic Undeployment of Services in a Computing Network", and U.S. Pat. No. ______ (Ser. No. ______) which is titled "Dynamic Redeployment of Services in a Computing Network", both are which are commonly assigned to International Business Machines Corporation and which were filed concurrently herewith.[0002] 1. Field of the Invention[0003] The present invention relates to computer networks, and deals more particularly with methods, systems, and computer program products for dynamically deploying services (such as web services or other network-accessible services) to various sites within a network.[0004] 2. Description of the Related Art[0005] Web services technology is rapidly emerging as a mechanism for distributed application integration. In general, a "web service" is an interface that describes a collection of network-accessible operations. Web services fulfill a...

This approach, however, places a heavy demand on the enterprise computing resources.

In these cases, the content distribution process will typically result in reduced response time as well.

When the business logic remains within the heart of the enterprise, network efficiencies are not realized and the enterprise may continue to be a processing bottleneck and a limiting factor in growth of the business.

Furthermore, the static deployment of presentation logic at the network edge is only efficient so long as usage patterns remain constant and predictable: if the usage patterns change, the statically deployed logic might no longer b
