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.

The Problem - Complexity, Cost, Lock-In

1 - To be effective, developers must learn several potentially complex APIs.
2 - This complexity leads to platforms becoming locked to specific technology stacks.
3 - Maintaining such systems ultimately carries significant cost in terms of time, resources and infrastructure.


The Solution - OpenMAMA

1 - Users only need to learn one API.
2 - Systems are no longer locked to specific vendors and products.
3 - Maintenance and support for the system becomes cheaper and easier.
