Commodity clusters
FoundationDB is designed for deployment on distributed clusters of commodity hardware running Linux.[7]
Replication
FoundationDB stores each piece of data on multiple machines according to a configurable replication factor. Triple replication is the recommended mode for clusters of 5 or more machines.
Scalability
FoundationDB is designed to support horizontal scaling though the addition of machines to a cluster while automatically handling data replication and partitioning.
Systems supported
FoundationDB supports packages for Linux, Windows, and Mac OS X. The Linux version supports production clusters, while the Windows and Mac OS X versions support local operation for development purposes. Configurations on Amazon EC2 are also supported.[8]
Programming language bindings
FoundationDB supports language bindings for Python, Go, Ruby, Node.js, Java, PHP, and C, all of which are made available with the product.[8]
