Prime swap business platform ecosystem consists of many large, medium and small components requires going through a strategic rewrite from a 3-tier legacy monolithic database-oriented design to a distributed, scalable microservice based architecture on cloud platform.

The objective of this new strategic platform is to provide competitive advantage to Delta One business by supporting larger business offerings, greater volume and better performance with horizontal scaling, improve stability, reliability & overall product quality.

Every milliseconds hundreds of trade event streams are received from middle office systems to the swap calculation engine, it has to recalculate whole swap valuation based on these delta’s with retrospective effect, which is a very CPU intensive operation. For a successful calculation the engine has to receive data from many peripheral systems, including rates, risks, market data, positions etc.

While processing such a massive data of millions of trades we wanted to minimize disk IO operations therefore this entire calculation process is executed in-memory and a live data stream handle is provided directly to Amazon S3 for persistence and downstream reporting systems.
