Gateway Operational Layer

The Gateway Operational layer provides the core functionality of the gateway.

The Gateway Operational layer consists of the following subcomponents:

Core Engine

The Core Engine is a high-performance, event-based, service-request routing engine that receives requests as events and uses the rules engine to determine where requests are handled.

The Core Engine can be used as follows:

  • With cache enabled

    The cache-enabled Core Engine does not require the Cache Agent.

  • Without cache enabled

    The Core Engine without cache enabled requires the Cache Agent to run separately.

Cache Agent

The Cache Agent stores the cache data for all objects of the cluster.

Apache HTTP Server (Optional)

You can use the Apache HTTP server as follows:

  • Reverse Proxy with HTTP channel (use the Apache HTTP server as it is)
  • Apache Module for RV channel (Optional)

    The Apache module is used to terminate an incoming request through the HTTP(S) transport. This module communicates with the facade component to forward the requests for further processing.
