To securely and efficiently save huge data amounts is indespensible to life for a lot of companies. Today data bases are a major component of many software systems. Thereby not only a permanent data availabilty counts, but also the user shoul be able to access the data as fast as possible.

Those high requirements for high availability and performance are no problem for the com.oonics Data Base Solutions. The cluster technology being used, enables that a data base can parallely run on multiple nodes. During going live it means a maximum capability and in case of a failure, the breakdown of a single node will be absorbed by the others. Thereby the data base keeps on running and the data security is sustainable.

Another weak point of conventional data base server is the rapidly achieved limit of users, which the system is still able to handle. The com.oonics Solutions are highly scalable and if required they can be uprated by an additional node, which increases the computing power of the system. Also the com.oonics Data Base is flexible enough to compensate an explosively increase of amount of data via the integration of additional SAN hardware.

Furthermore the com.oonics solution stands out for a simple management. The cluster can be dynamicly spanned and data bases, depending on the size and power requirements can be moved to a tailored cluster configuration. If the requirements change, it can be distributed again. Thus the available ressources on the com.oonics Data Base Cluster can be optimally been used at any time. This is especially benefiting if a lot of data bases have to be hosted.
