# What is MySQL?
MySQL is the world's most popular open source database. With its proven performance, reliability and ease-of-use, MySQL has become the leading database choice for web-based applications, covering the entire range from personal projects and websites, via online shops and information services, all the way to high profile web properties including Facebook, Twitter, YouTube, Yahoo! and many more.

# What is MySQL Cluster?
MySQL Cluster is built on the NDB storage engine and provides a highly scalable, real-time, ACID-compliant transactional database, combining 99.999% availability with the low TCO of open source. Designed around a distributed, multi-master architecture with no single point of failure, MySQL Cluster scales horizontally on commodity hardware to serve read and write intensive workloads, accessed via SQL and NoSQL interfaces.
