HashiCorp Consul Cluster
Consul is a networking tool from HashiCorp that provides service discovery, health checking, a distributed key-value store, and service mesh capabilities for distributed systems. It lets services find and securely communicate with one another across dynamic, multi-datacenter infrastructure.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| three-server-cluster | 6 | consul-server, consul-client |
| five-server-cluster | 8 | consul-server, consul-client |
What drives the cost
- Registered service instances
- Total number of registered service instances across the cluster. Drives server memory for catalog state and health check processing.
- Client agent node count
- Number of nodes running Consul client agents. Drives gossip protocol overhead and server heartbeat processing.
