FoundationDB is a distributed datastore, designed from the ground up to be deployed on clusters of commodity hardware. These clusters scale well as you add machines, automatically heal from hardware failures, and have a simple API. The key-value store supports fully global, cross-row ACID transactions. That’s the highest level of data consistency possible. What does this mean for you? Strong consistency makes your application code simpler, your data models more efficient, and your failure modes less surprising.
