I am Redis

I am Redis

Redis everywhere: Spring Session, Redis Cache with Spring Boot, Redis used with logstash. But what is Redis? What can I do with it?

This talk takes away the mystery from Redis and will give you an introduction to what Redis is, what it does, the typical use cases and how to set up Redis.
