NetScaler VPX Overview

Complete application acceleration in a simple virtual appliance

NetScaler VPX is a software-based virtual appliance providing the comprehensive NetScaler feature set. As an easy-to-deploy application delivery solution that runs on multiple virtualization platforms, NetScaler VPX can be deployed on demand, anywhere in the datacenter, using off-the-shelf standard servers. The simplicity and flexibility of NetScaler VPX make it simple and cost-effective to fully optimize every web application and more effectively integrate networking services with application delivery.

Accelerated deployment with enhanced scalability

NetScaler VPX runs on off-the-shelf servers with multiple hypervisor options, enabling new NetScaler instances to be rapidly provisioned anywhere in the datacenter that load balancingapplication acceleration and application security are required. Performance capacities can be upgraded in the field within minutes with the simple addition of a Pay-As-You-Grow license.

Lower total cost of ownership

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.

High availability for Citrix XenApp and Citrix XenDesktop

Local and global server load balancing (GSLB), along with secure remote access, improve availability and security for Citrix XenDesktop and Citrix XenApp deployments without the need to deploy hardware appliances into the Citrix environment. Policy wizards enable quick and safe XenDesktop and XenApp configuration.

Application delivery for small business

NetScaler VPX brings advanced application delivery functionality within reach of organizations that may not have the budget or specialized IT expertise to purchase and install a traditional hardware-based appliance. Unlike competing solutions, the NetScaler VPX virtual appliance provides 100 percent feature parity with its appliance equivalents.

Architecting private/public cloud infrastructures

The adoption of cloud computing creates significant networking challenges, including the need to provide self-service capabilities and deliver elastic provisioning of application delivery services. As a software-based virtual appliance, NetScaler VPX enables rapid on-demand provisioning in both public and private cloud infrastructures. The solution's RESTful APIs are leveraged by leading cloud providers to develop self-service capabilities and dramatically reduce overall deployment cost.

Utilizing NetScaler within non-production environments

NetScaler VPX can be deployed within development, testing and staging environments, prior to promotion into production. This approach supports an improved assurance process and eliminates the cost and logistics of dedicating physical appliances for use within application development areas. NetScaler policy configurations defined in the development lab can easily be moved into production. The inherent flexibility of the virtual appliance model enables NetScaler VPX to be evaluated as part of the full application lifecycle process.

Architecting scalable multi-tenant infrastructures

In flex-tenancy architectures, application delivery is segmented into two tiers: a flex tier at the datacenter edge for shared network services using NetScaler MPX appliances, and application-specific tenant tiers using NetScaler VPX instances in close proximity to each application. Applications that vary significantly by tenant are optimized via dedicated VPX instances. Policies are tailored to the specific needs of particular tenants—whether they are defined as an application, line of business or user.

Attractive application delivery options for smaller businesses

NetScaler VPX is ideal for small to mid-size businesses to improve widely-deployed applications, such as XenDesktop and XenApp, as well as popular applications including Microsoft Exchange and SharePoint. Support for AppExpert templates enables fast and easy configuration for these and other applications.

NetScaler VPX is available in a variety of models to suit the most demanding IT and business needs. If additional throughput is needed, some models also support Burst Pack and Pay-As-You-Grow options to help protect your initial investment and make it easier to scale up your network with a simple software license upgrade.
