WSO2 Gateway is a high performance message gateway that encapsulates messaging between disparate systems. It uses a fully decoupled architecture with the Carbon Message as the data carrier between protocol handling layers and the message processing engine. The gateway supports thousands of concurrent HTTP/S connections using Netty and Disruptor for high performance. It can route messages using Apache Camel and define REST APIs. Performance tests show it is around 10x faster than the existing WSO2 ESB and can handle more concurrent connections. The gateway is targeted for use in API gateways, load balancers and other integration patterns.
