How Web giants store big—and we mean big—data

The Great Disk Drive in the Sky: How Web giants store big—and we mean big—data.

The need for this kind of perpetually scalable, durable storage has driven the giants of the Web—Google, Amazon, Facebook, Microsoft, and others—to adopt a different sort of storage solution: distributed file systems based on object-based storage. These systems were at least in part inspired by other distributed and clustered filesystems such as Red Hat’s Global File System and IBM’s General Parallel Filesystem.

And one more blurb…

Google wanted to turn large numbers of cheap servers and hard drives into a reliable data store for hundreds of terabytes of data that could manage itself around failures and errors. And it needed to be designed for Google’s way of gathering and reading data, allowing multiple applications to append data to the system simultaneously in large volumes and to access it at high speeds.
