Citrix has added native SQL support to its application delivery NetScaler product to boost the performance of SQL applications.
The DataStream technology, announced on Tuesday, is an add-on for the NetScaler application delivery controller (ADC). It allows databases to be secured via real-time traffic inspection from both physical or virtual NetScaler appliances and uses connection multiplexing to take the strain off backend database servers. It also allows the ways databases map to external servers to be managed, taking weight off application specific programming.
The add-on should allow databases "to be scaled far more efficiently, it will reduce the amount of physical infrastructure needed to run them and provide security benefits as well," Damian Saunders, director of the datacentre and cloud group at Citrix, told ZDNet UK on Tuesday. "Another benefit is by taking the responsibility and tasks away from application level code and putting it on the NetScaler, it means changes in applications can be done without changing the way the database code maps to database servers."
It can natively pass structure query language (SQL), tabular data stream (TDS) and Oracle MySQL protocols.
Because it can parse the protocols, the technology can also apply detailed user access policies to each database user in realtime, and store a log of all SQL transactions to provide a reference in case of SQL injection attacks.
DataStream was made available on Tuesday for NetScaler version 9.3 at no additional cost. It is available as a download for a virtual appliance, and physical appliances can be upgraded as a part of their maintenance contracts.
