Consul - an introduction in the context of load balancing
Last updated
What is Consul - an introduction in the context of load balancing?
Consul is a distributed, highly-available, and multi-datacenter aware service discovery and configuration tool developed by HashiCorp. It can be used to implement load balancing in a PostgreSQL cluster to distribute client connections and queries evenly across multiple backend nodes.
Consul uses a consensus protocol for leader election and ensures that only one server acts as a leader at any given time. This leader automatically takes over upon leader failure or shutdown, making the system resilient to outages. It provides a range of services like service discovery, health checking, key-value storage, and DNS services.
