Systems and methods for dynamic component versioning

摘要: The deployment and management of differing versions software components can be simplified. External interfaces the component remain constant in behavior while internal logic, possibly storage, change between versions. Such a version system transparent to client programs, since backwards compatible This transparency greatly reduce risks unpredictable or failure. A maintain each component, use dispatch technique determine instantiate currently active whenever requests service from during session. Old instances, other versions, maintained as long required on server. systems apply stateful stateless components, using synchronous asynchronous communications, which may communicate over networks web services type protocols. description is not intended complete of, limit scope invention.
