Abstract

Managing a web service provided by a plurality of servers coupled to a data communication network. Two versions of the web service are executed on the plurality of servers and a selected version of the web service is identified for execution based on a request from a user for access the web service. While access to the web service is permitted via at least one server, the web service is updated on at least one other server. One or more servers providing the web service may specify a default version of the web service as the selected version if the request from the user does not specify a version of the web service for access.
