Method and system for executing an operation in a distributed environment

摘要

A system, method, and computer readable-medium for performing operations associated with browser requests are provided. The system includes a plurality of dispatchers coupled to a plurality of web listeners. Each of the dispatchers receives from a corresponding web listener browser requests received by the corresponding web listener. The dispatchers are configured to send messages through an inter-machine communication mechanism to cartridge instances. The messages cause the cartridge instances to perform the operations associated with the browser requests. Each cartridge instances includes a cartridge execution engine and a cartridge. The cartridge execution engine handles all inter-machine communication with the dispatchers, and passes the requests to the cartridges by making calls into the application programming interface of the cartridge. Consequently, cartridges are isolated from the complexities of inter-machine communication, and may therefore by used in a highly distributed system without being distribution-aware.
