How do I get scalability for Redis?

To get scalability, several Redis instances must be deployed and started. Distribution and sharding are done on client-side (i.e. the developer has to take care of them). If you compare them to a unique Redis instance, most RDBMS provide more scalability (typically providing parallelism at the connection level).
