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.

Consul runs on Linux, macOS, FreeBSD, Solaris, and Windows and includes an
optional browser based UI. A commercial version
called Consul Enterprise is also
available.

Please note: We take Consul's security and our users' trust very seriously. If you
