Citrix Systems has shown new nCore technology that allows its high-end Citrix NetScaler appliances to deliver Web 2.0 applications and cloud services for more users with no new hardware investments required.

By upgrading their existing NetScaler appliances to the new nCore powered software, Citrix customers can access all the power of the multi-core Intel processors that power NetScaler MPX hardware appliances, allowing them to run far more web acceleration and security functions in parallel, the company said.

This flexible software-based approach to scalability stands in stark contrast to traditional networking vendors who rely on proprietary ASIC-based processors and custom networking hardware, making it difficult for them to keep pace with the rapid changes in today's web and cloud computing architectures without "forklift" hardware upgrades.

NetScaler nCore is reportedly engineered specifically to optimise next-generation web applications and services in software by using the underlying capabilities of general purpose multi-core hardware.

NetScaler MPX appliances powered by nCore are capable of processing multiple complex operations on each application workload in parallel, while maintaining multi-gigabit performance and exceptionally low application latencies to ensure the best user experience.

Leveraging the ultra-fast packet engine in NetScaler across multiple CPU cores brings unmatched scalability and performance for optimising a wide range of application delivery services and workloads.

"The past decade saw a mass migration to browser-based enterprise applications targeting business processes and user productivity as well as increasing adoption of service-oriented architectures (SOAs), web 2.0 and now cloud computing models. These approaches tend to place increased demand on the infrastructure, because of "chatty" and complex protocols," said Mark Fabbi, VP and distinguished analyst at Gartner.

"Without providing features to mitigate latency, to reduce round trips and bandwidth, and to strengthen security, these approaches almost always lead to disappointing performance for enterprise and external users."

"We are very excited to announce the addition of nCore technology to our NetScaler platform because it provides our customers far greater scalability and performance with no additional hardware investment. This technology gives us the right software architecture to extend our multi-year performance leadership, while enabling the flexibility to meet emerging web application delivery requirements," said Klaus Oestermann, group vice president and general manager of the NetScaler Product Group.
