memcached is a database now? IMHO Redis barely registers as a database; it's more of a shared heap that supports snapshotting. At Instagram we use PostgreSQL, Redis, and Cassandra.

It's a place where data is stored. Wikipedia says "A database is a structured collection of data." I think redis qualifies given that description, but I agree it's different enough to raise eyebrows if someone referred to it as their "database".

What constitutes a DB? Can we have "custom" as an option? We wrote 2 very light, single-use DB's for two specific use cases in order to get some performance we needed on real-time data, but they don't really have any kind of management or generic SQL-like access.

Most companies usually use more than one. At my current job we use PostgreSQL and MySQL in production, and H2 in development. At my previous job we used Sybase SQL Anywhere (horrible, wouldn't recommend it), Microsoft SQL server, MySQL, Amazon RDS and H2.

I don't have the best knowledge on DBs, but why would you use more than one of the same "tech"/paradigm? Why postgreSQL and MySQL? Don't they work similarly? Or is it because you use postgreSQL for the things it is better than MySQL, and vice-versa?
