I-RMI: Performance Isolation in Information Flow Applications
A problem with many distributed applications is their behavior in lieu of unpredictable variations in user request volumes or in available resources. This paper explores a performance isolation-based approach to creating robust distributed applications. For each application, the approach is to (1) understand the performance dependencies that pervade it and then (2) provide mechanisms for imposing constraints on the possible ‘spread’ of such dependencies through the application. Concrete results are attained for J2EE middleware, for which we identify sample performance dependencies: in the application layer during request execution and in the middleware layer during request de-fragmentation and during return parameter marshalling. Isolation re the novel software abstraction used to capture performance dependencies and represent solutions for dealing with them, and they are used to create (2) I(solation)-RMI, which is a version of RMI-IIOP implemented in the WebSphere service infrast...
