Consul is a service networking solution created by HashiCorp and written in Go. It provides service discovery, health checking, a distributed key-value store, secure service-to-service communication via mTLS (Consul Connect), and multi-datacenter federation.
Consul is widely deployed as the backbone of zero-trust networking and service mesh architectures in production environments at scale.
Service networking platform. Service discovery, configuration, and segmentation across any infrastructure.
✨ Features
DNS or HTTP interface for service lookup. Clients find services without hardcoded addresses.
TCP, HTTP, gRPC, script-based checks. Unhealthy services removed from rotation automatically.
Service mesh with mTLS. Encrypted service-to-service traffic with identity-aware authorization.
Distributed key-value store for runtime configuration. Watch keys, react to changes live.
Federate clusters across datacenters and clouds. WAN gossip for cross-region service discovery.
