Cloud computing is a collection of the integrated computing systems over a network, and being one of the many technologies that are currently carried out various development efforts. For database systems, cloud technology using MySQL as one of option for its database management. For huge traffic in the cloud system, MySQL cluster has better performance than the non-cluster, but the comparison is not known yet. This research aims to find a good comparison of performance between MySQL Server and MySQL Cluster on cloud computing system, by measuring multiple parameters using the simple, complex, non-transactional and readonly method, with various request maximum from 10000 to 50000. The result are in terms of time, the MySQL Server’s processing speed is better than MySQL Cluster, but for the performance, MySQL Cluster is still better, since it has high availability feature.
