Citrix® NetScaler® VPX: Optimizing availability, performance and security for virtualized applications

An explosion in the cost, complexity and number of virtual applications is leading to out-of-control server sprawl for a growing number of organizations. Add to that the move toward more interactive and collaborative applications with Web 2.0 capabilities, and IT professionals are seeing some serious pressure on their organizations’ existing network infrastructures, not the least of which include meeting the expectations of users for 24/7 application availability and top-notch performance, and avoiding untold online security risks posed by the new virtualized application reality.

Unfortunately, throwing more servers, bandwidth and equipment at the problem is no longer an answer – if it ever was. In fact, doing so only adds cost and complexity to an already strained application delivery infrastructure.

Enter Citrix® NetScaler® VPX. This all-in-one virtual application delivery solution reduces the infrastructure’s number of servers and network devices and responds dynamically to changing workloads to ensure applications and services are always available offering:

  • Load balancing and intelligent application-layer health checks for 100% availability to web, application and database resources
  • Global server load balancing for business continuity and disaster recovery in multiple data center environments
  • Increased security with an integrated application firewall
  • Substantially lowered costs by offloading servers.

100% applications uptime 

NetScaler VPX’s proven layer 4-7 load balancing ensures 100% application and database uptime and no single point of failure by directing users to the right application and database resource. This powerful load balancing is extended worldwide with integrated Global Server Load Balancing (GSLB) to efficiently and intelligently distribute application traffic across multiple data centers, enabling a resilient disaster recovery solution.

Accelerated application performance

With NetScaler VPX, applications run up to five times faster, improving productivity and delivering a better overall experience. Smart use of compression, caching and protocol optimizations accelerates application response times for all users.

Microsoft Exchange 2010, Lync and SharePoint are just three of many applications for which NetScaler provides proven interoperability, enhanced availability and faster performance.

NetScaler protects applications from attack

NetScaler VPX also protects businesses from a growing number of application-layer attacks and prevents the loss of valuable corporate and customer data via an integrated web application firewall.

In addition to proven attack defenses, Application Firewall aids in compliance with information security regulations, such as PCI-DSS. Comprehensive AAA capabilities, combined with a powerful distributed denial of service (DDoS) shield, allow secure application access and security while preventing unauthorized and disruptive access to sensitive information.

NetScaler accelerates deployment with enhanced scalability

NetScaler VPX runs on off-the-shelf servers with multiple hypervisor options, enabling new NetScaler instances to be provisioned anywhere in the data center that load balancing, application acceleration and application security are needed.

NetScaler reduces TCO

NetScaler VPX helps organizations control costs by leveraging processing capacity already in place, including existing virtualized servers and associated resources. Multiple NetScaler VPX instances can be deployed on a single server to maximize utilization of hardware infrastructure, and low-cost commodity server platforms can be used for load balancing and other application delivery needs without creating dependence on specific server hardware.

NetScaler VPX is a simple, cost-effective, easy-to-deploy solution that can help organizations build and manage a fast, responsive and secure IT environment through the delivery of comprehensive application acceleration, load balancing and web security.  

Citrix NetScaler VPX can improve your virtualized application environment: Reduces server costs by 60 percent Accelerates web applications by five times Optimizes Web application delivery infrastructure Improves operational efficiency and security through integrated firewalls Responds to periods of high demand by dynamically provisioning more capacity Migrates applications from one set of resources to another Spins up additional instances of an application when demand exceeds resources available.
