Why OpenMAMA?
Get Up & Running

Messaging middleware sits at the lowest tier of the enterprise technology stack, making it difficult, expensive and risky to modify adjacent systems and applications. Furthermore as market fragmentation continues and data volumes grow exponentially, firms’ market data environments present some serious obstacles for managers tasked with controlling their departments IT spend with innovating both their applications and their infrastructure.

OpenMAMA solves this problem by providing a mature abstraction layer that allows users to interface with a variety of middleware systems whilst providing a uniform API for all messaging applications. At its core, OpenMAMA has been designed to provide users with the flexibilty to create applications without being concerned about the requirements or structures of an underlying messaging middleware, or the fear of developing software that is heavily coupled to a specific platform.

By providing a consistent, well designed, and open standard, users can eliminate the threat of vendor lock-in by enabling their applications to switch middlewares without lengthy code changes; or port applications between different supported platforms with minimal friction. Using OpenMAMA, investment in development becomes a one off, up front effort, and users can focus their efforts more on building the applications they need, rather than worrying about the tricky internals of middleware semantics.
