MySQL was founded in 1995 and went open source in 2000. MySQL was the database for phpWebLog, for example, way back in 2000. But, for a long time, you needed to be comfortable with mysqldump or other backup / restore methods to move servers or providers. But WordPress brought MySQL and open source to the masses.

Sharding: Sharding is the concept of splitting data horizontally, i.e. by distributing data into multiple servers (shards), meaning that the different portions of data for a given table, may be stored on many different servers. This can help to split large data sets into smaller ones stored in multiple servers. ibd -rw-r --.

The hosting provider had given them ownership of an internal IP subnet, and so they started out with two load-balanced public web servers: X.X.X.100 It's easy enough to upgrade load-balanced web servers. It's not so easy with a junk drawer server.
