Overcast’s simple architecture and focused approach to enterprise-grade integration means that its runtime performance profile is very fast and the bottleneck is the API of the systems being connected. The Overcast Service on its own moves 1 million records from SAP to SQLServer in under a minute!
At its core it is a secure, authentication based integration platform that performs protocol conversion between the systems, maps to appropriate types in appropriate objects and only adjusts values where absolutely necessary (e.g. try putting SAP’s typical date of “31st December, 9999” into Salesforce!).
Overcast synchronous integrations can also return results directly rather than inserting the results into System-of-Engagement objects (making it easy to build responsive web applications that are directly involved with your hybrid business process).
Also, thanks to the simple architecture of the Overcast servers, it is very easy to both scale-up and scale-out. It maintains minimal state and can be readily scaled-out by simply adding more nodes to the Overcast cluster. New nodes automatically configure, download the latest metadata, and register themselves. They are then instantly usable in a load-balanced production environment.
