An API gateway sits between a client and a collection of backend services.

It’s common for an API gateway to handle tasks that are common to the API services context, such as: routing, user authentication, throttling, limiting, policies, error handling, failover and statistics.

Key features:

• Light API Gateway / Load Balancer powered by Apache Camel dynamics routes.
• Optional Spring Security OAUTH2 protected CAPI Manager API.
• Distributed tracing system (Open Telemetry Collector / Zipkin)
• Metrics (Prometheus)
• CAPI Browser user interface for route management.
• Rest API for Route management.
• Load Balancer (Round robin)
• Failover (With and without Round Robin)
• Tenant support (Headers)
• Stick Session (Cookies and Headers)
• Certificate Manager (using the CAPI Manager API)
• Supports Hashicorp Consul for service discovery
