Citrix NetScaler DataStream

The DataStream technology is a part of a product line for delivery of services and creation of computer networks of NetScaler. Thanks to DataStream technology, NetScaler in the market provides with the controller of delivery of services the high level of scalability, availability and security not only for web applications, but also for data processing systems, for suppliers of corporate, cloud and mobile systems.

Today all companies regardless of the size face a problem of active increase in volume of the processed data. This it is connected with the general trends, such as growth of popularity of social networks, video and web applications and also use of consumer devices for work. Need of ensuring availability and information analysis imposes more high requirements to traditional databases, distributed systems of storage and unstructured file systems, such as Hadoop. As a result there was a need for solutions which could provide effective scaling, security and optimization of infrastructure of storage and data transmission.

The NetScaler DataStream technology solves this problem using the analysis of traffic in real time, applications of optimization methods and security. This first network solution in which the natural protocol of data processing and an analysis system of transactions are applied to work both with structured, and with unstructured data. During the work with such databases, Oracle MySQL as well as Microsoft SQL Server, the NetScaler DataStream technology makes possible scaling of infrastructure of storage and information transfers, managing exacting server connections to the database to resources of the processor and memory.

For providers of the cloud systems experiencing three times a heavy load on the database than the typical corporate client, creation of economic infrastructure of the database with the high level of scaling is also key advantage. The new NetScaler DataStream technology also helps the companies to carry out horizontal scaling of DPC and the private cloud systems using optimum allocation of load of SQL queries of the most suitable and available servers. This technology also gives the chance to users to set safety rules which provide the increased protection, control and audit of data in real time.

Main Features:

• The built-in SQL language – Thanks to new DataStream technology, NetScaler can trace traffic in real time using natural instructions and the rules SQL during the work with the Microsoft SQL Server and MySQL servers now. During the work with Microsoft SQL Server NetScaler analyzes the Tabular Data Stream (TDS) protocol, providing uniform methods of management and control together with Microsoft System Center. When using with Oracle MySQL NetScaler the politician and complex monitoring for ensuring safe work of the large-scale systems of on-line transaction processing (Online Transaction Processing) gives an opportunity of balancing of loading of SQL queries, control.
• Unloading of a database server – the Solution NetScaler with DataStream technology provides multiplexing of SQL connections, considerably reducing number of connections to key date servers, optimizes infrastructure of databases, allowing to scale effectively it for placement of bigger quantity of a DB. Possibilities of NetScaler on management of the SQL connections provide an economic method of consolidation and virtualization of database servers.
• Economic horizontal scaling – Thanks to the built-in support of the protocol SQL, NetScaler with DataStream technology provides advanced balancing of loading and the principle of condition monitoring for ensuring the highest performance level, efficiency and reliability. The companies can set own rules, using a possibility of redirection of database requests on the optimal server. For example, it is possible to send all inquiries for reading from the database to the server pool working in the read-only mode. This function provides also the highest stability at the effective cost level at the expense of an advanced monitoring system of a status of a DB. In particular, control of redirection of SQL queries only on operational internal servers is provided. In combination with a large number of opportunities of balancing of loading, including global balancing of loading of servers (global server load balancing - GSLB), active monitoring of database servers increases efficiency and is a remarkable alternative to expensive solutions of a clustering of a DB.
• Data security and tracking of threats – the New DataStream technology allows to apply safety rules and at the user level to control access to internal database servers. It gives the chance of NetScaler to analyze all transactions of SQL, to perform check on compliance to the SQL protocol and also to control data access. Requests for data access can be checked and registered for the analysis of compliance to safety rules. As a result, NetScaler gives a complete idea at the level of Web servers, applications and databases for ensuring complete security and risk management in DPC or the cloud systems.

Prices and availability

The DataStream technology is available in the version of NetScaler 9.3. The additional functionality is provided free of charge to all customers of NetScaler. The new DataStream technology is available both on the physical NetScaler MPX servers, and on the virtual servers NetScaler VPX.
