The days of the single source of truth, one database for the entire enterprise, are over. Now even a relatively simple mobile application demands more than one database. The good news is that we have entered a golden age of open-source NoSQL databases. Developers have great and readily available open-source technologies with robust communities behind them at their fingertips.

The difficulty is knowing which database is right for which use case. While a number of options are available, according to Redis Labs, these are five NoSQL databases that developers should be familiar with.

Redis Labs offers enterprise-class Redis and Memcached for developers. Their fully-managed cloud services - Redis Cloud and Memcached Cloud - deliver top performance in a highly-available, infinitely scalable, predictable and stable manner — freeing developers from dealing with nodes, clusters, scaling, data-persistence and failure recovery.
