When is it used?

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.

Architecting scalable multi-tenant infrastructures

In flex-tenancy architectures, application delivery is segmented into two tiers: a flex tier at the datacentre 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.

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.
