This section will excite programmers the most. Let's get our hands dirty and punch in some code. But, before that, we have to understand that Redis works on a client-server model and uses the Redis protocol to communicate with the server. For the client to connect to the server, the client has to know the location of the server. For this section, I am going to show samples using the redis-cli and Java clients.
