HashiCorp Consul is a service networking platform providing service discovery, service mesh and secure service-to-service connectivity across on-premises, hybrid and multi-cloud environments. First released in 2014 by HashiCorp, the infrastructure software company founded in 2012 by Mitchell Hashimoto and Armon Dadgar, Consul now operates as part of IBM following IBM's 6.4 billion dollar acquisition of HashiCorp, completed in February 2025.
Consul works consistently across virtual machines, bare metal and Kubernetes, which distinguishes it from Kubernetes-only service mesh options, and is commonly adopted by teams already using other HashiCorp tools like Terraform and Vault.
Consul provides service discovery and health checking via a distributed catalog backed by the Raft consensus algorithm, plus a key-value store for dynamic configuration. Its service mesh mode deploys sidecar proxies, typically Envoy, to encrypt traffic with mutual TLS and enforce identity-based intentions that define which services may communicate.
Layer 7 traffic management enables canary deployments and service splitting, and multi-datacenter federation lets a single mesh span multiple clouds and on-premises data centers. API and ingress gateways expose mesh services to external clients or connect separate meshes together.
Consul Community Edition is free, open-source and self-hosted, released under HashiCorp's Business Source License since August 2023, with no functional limits on core service discovery and service mesh capabilities.
HCP Consul Dedicated is a managed SaaS offering with usage-based pricing, historically including a low-cost development tier and a production tier billed hourly plus a per-service-instance fee. Consul Enterprise is a self-managed license with advanced features like namespaces, admin partitions and automated backups, priced through a custom sales quote.
Consul is used for service discovery and service mesh, letting distributed applications find each other, communicate securely with mutual TLS, and enforce identity-based access control across on-premises, hybrid and multi-cloud environments.
Yes, Consul Community Edition is free and open source for self-hosted deployment. HashiCorp also offers a paid managed cloud service (HCP Consul Dedicated) and a paid Enterprise self-managed license with additional features.
HashiCorp, the company behind Consul, was acquired by IBM in a deal valued at approximately 6.4 billion dollars that closed in February 2025. Consul continues to be developed under the HashiCorp brand as part of IBM.
Yes, Consul supports Kubernetes as well as virtual machines and bare metal, allowing a single service mesh to span mixed runtime environments.
Consul works across VMs, bare metal and Kubernetes, while Istio is built specifically for Kubernetes. Consul also integrates natively with other HashiCorp tools like Vault and Terraform.
Consul was first released by HashiCorp in 2014, several years after HashiCorp itself was founded in 2012 by Mitchell Hashimoto and Armon Dadgar.
