HashiCorp Consul - Connect and Secure Any Service

Service-based networking for dynamic infrastructure

Static Infrastructure

Private datacenters with static IPs, primarily north-south traffic, protected by perimeter security and coarse-grained network segments.

Traditional Approach

Static connectivity between services
A fleet of load balancers to route traffic
Ticket driven processes to update network middleware
Firewall rule sprawl to constrict access and insecure flat network zones

Dynamic Infrastructure

Multiple clouds and private datacenters with dynamic IPs, ephemeral containers, dominated by east-west traffic, no clear network perimeters.

Consul Approach

Centralized registry to locate any service
Services discovered and connected with centralized policies
Network automated in service of applications
Zero trust network enforced by identity-based security policies

Consul Use Cases

Service Discovery and Health Checking

Enable services to locate other services running in any environment and provide real-time health status.

Consul Ecosystem

The Single Control Plane for Cloud Networks

Consul provides the control plane for multi-cloud networking.

Centrally control the distributed data plane to provide a scalable and reliable service mesh
Automate centralized network middleware configuration to avoid human intervention
Provide a real-time directory of all running services to improve application inventory management
Enable visibility into services and their health status to enhance health and performance monitoring
Automate lifecycle management of certificates which can be issued by 3rd party Certificate Authority
Provide unified support across a heterogeneous environment with different workload types and runtime platforms

Consul Case Studies

Delivering network as a service in a heterogeneous environment

Bloomberg builds a service discovery platform to connect more than 20000 nodes across a complex and diverse environment. The platform allows thousands of developers to register and connect their applications with each other in a self-service manner.
