Consul vs Zookeeper vs etcd: What are the differences?
Service discovery tools help services find and communicate with one another. The rise of containers has increased the need for such services. Zookeeper originated in Hadoop for use in Hadoop clusters. It’s the most mature of these three options. etcd is a newer option known for its simplicity and ease of use. Consul is a bit more comprehensive than the other two options, offering not only a key value store but also a built-in framework for service discovery.
