Consul

HashiCorp Consul is a service networking solution providing service discovery, secure service mesh with mutual TLS, dynamic traffic routing, and distributed key-value storage.

When to Use

• Service Discovery & Health Checking: Dynamic registration and lookup of microservices across hybrid cloud networks.
• Service Mesh & Mutual TLS (mTLS): Enforcing zero-trust encryption and authorization between microservices via Envoy sidecars.
• Distributed Key-Value Store: Centralized runtime configuration and dynamic feature flags.
• Multi-Datacenter Federation: Connecting and discovering services seamlessly across multiple cloud providers and regions.

Quick Start
