A distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
- Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
- Service Mesh - Consul Service Mesh enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections with Transparent Proxy.
- API Gateway - Consul API Gateway manages access to services within Consul Service Mesh, allow users to define traffic and authorization policies to services deployed within the mesh.
- Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
- Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
- Dynamic App Configuration - An HTTP API that allows users to store indexed objects within Consul, for storing configuration parameters and application metadata.
