-YDB was designed from scratch as a response to growing demand for scalable interactive web services. Scalability, strict consistency and effective cross-row transactions were a must for such OLTP-like workload. YDB was built by people with strong background in databases and distributed systems, who had an experience of developing No-SQL database and the Map-Reduce system for the one of the largest search engine in the world.

-We found that YDB's flexibles design allows us to build more services on top of it including persistent queues and virtual block devices.

### Horizontal scalability

-Unlike traditional RDMBS YDB [scales out](https://en.wikipedia.org/wiki/Scalability#Horizontal_or_scale_out) providing developers with capability to simply extends cluster with computation or storage resources to handle increasing load.

Current production installations have more than 10,000 nodes, store petabytes of data and handle more than 100,000 distributed transactions per second.
