Hosting provider business based on Parallels solutions grows rapidly day by day. Increasing accounts number and resources volume used by them calls for loading of MySQL server. Rising accounts-related activity and extending set of nodes (Parallels Virtuozzo Containers, Plesk, SiteBuilder, etc.) increases Parallels Business Automation - Standard back-end and front-end parts load. Hardware resources consumption exceeds a reasonable limit. The only one solution of the problem is increasing hardware resources volume available both for Parallels Business Automation - Standard management server and MySQL server. However, upgrading hardware resources Parallels Business Automation - Standard is hosted on is not very efficient and scalable solution. The real way out is to use clustering technologies.
Another problem is ensuring an uninterrupted and reliable access to service. In the situation when a client base is massive, any minimal downtime of the management node provokes loss of clients and therefore, loss of returns. Parallels Business Automation - Standard management node and/or MySQL database server maintenance (upgrade, backup/restore operations, hardware problems and so on) produces such undesirable downtimes. The cluster technology will shorten or even allow avoiding downtimes and minimize related risks.
