Consul is a service mesh solution offering a full-featured control plane, including segmentation functionality, configuration, and service discovery. These features may be used individually as required, or they may be used together for creating a full-service mesh. Consul operates over a data plane and supports both a proxy and a native integration model. Consul ships with a simple built-in proxy that ensures everything works out-of-the-box. Consul also supports 3rd party proxy integrations, such as Envoy.
