We are excited to announce the release of HashiCorp Consul 1.2. This release supports a major new feature called Connect that automatically turns any existing Consul cluster into a service mesh solution. Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization.
Consul is currently deployed on millions of machines worldwide. After upgrading to Consul 1.2 and enabling Connect, any existing cluster will instantly become a service mesh solution that works on any platform: physical machines, cloud, containers, schedulers, and more. A service mesh is necessary for organizations adopting microservices and dynamic cloud based infrastructure.
Traditional host-based network security must be replaced with modern service-based security to accommodate the highly dynamic nature of modern runtime environments.
