MySQL, the world's most popular open source database manager is continuing its march into the Enterprise market with the introduction of MySQL Cluster.
The addition of clustering architecture to the product now means that it can deliver 99.999 per cent availability, making it suitable for business critical applications says developers MySQL AB.
Based on the NDB Cluster database technology MySQL acquired when it bought Alzato in October 2003, MySQL Cluster enables companies to run multiple servers each holding data as a single fault-tolerant system. Swedish based MySQL AB says that because the system is distributed there is no single point of failure and even when a hardware fault develops the Cluster provides sub-second response fail over, allowing the service to operate without any noticeable interruption.
The developers say that on a typical low-end hardware of a four-node cluster, with two CPUs per node, the MySQL Cluster offers response times of 5-10 milliseconds and throughput of 100,000 replicated transactions per second. The product doesn't require any shared disks and uses standard PC hardware which customers can scale as their business demands.
The introduction of MySQL Cluster will add further pressure on Oracle and Microsoft SQL Server for customers looking for a database manager which will do the job without the bells and whistles. Already well established at the small and medium sized markets where its reliability and low cost have made it almost ubiquitous, IT managers of larger companies who currently have expensive DBMS licences running on expensive hardware are likely to look seriously at the new product as a way of cutting costs.
