Consul vs Redis: What are the differences?
Consul: A tool for service discovery, monitoring and configuration. Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable; Redis: An in-memory database that persists on disk. Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
Consul belongs to "Open Source Service Discovery" category of the tech stack, while Redis can be primarily classified under "In-Memory Databases".
"Great service discovery infrastructure" is the primary reason why developers consider Consul over the competitors, whereas "Performance" was stated as the key factor in picking Redis.
Consul and Redis are both open source tools. Redis with 37.4K GitHub stars and 14.4K forks on GitHub appears to be more popular than Consul with 16.4K GitHub stars and 2.85K GitHub forks.
According to the StackShare community, Redis has a broader approval, being mentioned in 3265 company stacks & 1788 developers stacks; compared to Consul, which is listed in 134 company stacks and 55 developer stacks.
