Overview
Consul is a service networking solution providing service discovery, service mesh, and secure connectivity across diverse environments. It features a control plane for registering, accessing, and securing services, and a data plane with gateways and sidecar proxies for managing application traffic. The Consul catalog API tracks services for discovery and mesh use cases. Cluster consensus is ensured via the Raft protocol, while gossip communication manages membership. Consul offers both Enterprise and Community editions. It integrates with Terraform for infrastructure automation. Key capabilities include identity-based authorization, L7 traffic management, and service-to-service encryption. Consul enables use cases like securing microservices, managing traffic patterns, and automating network infrastructure changes based on service catalog updates, enhancing application resilience and agility.
