Programmable, asynchronous, event-based reverse proxy for JVM.
Styx is a programmable reverse proxy for JVM (Java Virtual Machine). It can be used as a stand-alone application, or as a platform to build custom networking applications. It is non-blocking, fully asynchronous and event driven therefore very scalable.
Styx Proxies HTTP requests to a configurable set of Backend Services typically a cluster of web servers (multiple origins) or load balancers (e.g. AWS ELB).
Requests are subjected to an interceptor chain (conceptualy a HTTP filter chain), which can respond or modify and pass through the request to the backend services. The interceptor chain can be easily extended by Plugins written in Java.
Styx additional capabilities: - Load balancing - Origin health checking - Retry mechanisms - Connection pooling - Admin dashboard (inspired and based on Hystrix Dashboard) - Performance and system metrics collection and reporting (Graphite compatible)
Most additional features can be extended via the Java Service Provider Interface (SPI) model.
The plugin and the SPI (Service Provider Interface) model enables developers to build custom HTTP applications easily on top of Styx, which takes care of common proxy server related functionality. Developers can then concentrate on the value-add business logic.
