To include Redis  within a comparison of persistent storages could see like some misunderstanding at first sight. On the other hand, there are certain use-cases allowing us to think about to store data in main memory, especially in private data centers. Primarily once your cluster includes a machine having almost equal size of hard drive and RAM :-) Redis is enterprise, or advanced, key-value store with optional persistence. There are couple of reasons why everyone loves Redis. Why I do? 1. It's pretty simple . Following command can install redis server on ubuntu. That's all. apt-get install redis-server 2.
