Leverage In-Place Processing Capacity

With Citrix NetScaler VPX, IT and service providers can take full advantage of virtualized servers and associated resources that are already in place and deploy application delivery controllers and remote access SSL VPN gateways on-demand anywhere in any network or data center. Citrix NetScaler VPX is not dependent on specific server hardware, which enables enterprises to exploit low-cost, commodity server platforms. In addition, multiple Citrix NetScaler VPX instances can be deployed on a single physical server to maximize utilization of hardware infrastructure. At the other end of the spectrum, service providers now have the option to utilize whatever special-purpose hardware — for example, NEBS compliant or DC-powered systems — from whatever source best meets their needs or internal standards. The ability to easily upgrade Citrix NetScaler VPX licenses and swap out underlying hardware platforms to up-size or down size an implementation as needed.

Citrix NetScaler VPX

Citrix NetScaler VPX makes functionality typically only offered on specialized, high-end network devices available as a virtual appliance that can be easily and dynamically deployed on a single server or across entire enterprise data centers. The simplicity and flexibility of Citrix NetScaler VPX makes it easy and cost-effective to fully optimize every application type. For example to provide secure remote access and high availability for any application type like Citrix apps, web and enterprise apps, cloud and SaaS apps, and mobile apps. Provision and de-provision Citrix NetScaler VPX on-demand in test and lab environments, telecom service and cloud provider environments. Cost effectively deploy full Citrix NetScaler VPX functionality in front of applications, such as Microsoft SharePoint and Office Communication Server. Unified Gateway is part of Citrix NetScaler VPX Enterprise and Platinum editions and offers secure remote access to any application whether it be web, legacy client-server, SaaS, mobile or Citrix apps.

Advanced Layer-4

Current SDN technologies operate at Layer-2 and Layer-3 and are missing the opportunity to truly deliver on the full promise of the solution. The next-generation NetScaler platform unifies best-in-class Layer-4 and Layer-7 network services into an application control layer, and can integrate this application control with both existing transport networks and emerging SDN technologies. This application control layer can make emerging Layer-2 and Layer-3 SDN architectures completely app-driven, by using app-centric definitions and policies to simplify network design, while making the whole network more intelligent.

With its centralized management plane, NetScaler alleviates the overhead and sprawl usually associated with serving complex networking applications. Through intuitive workflows, administrators can enable provisioning and deploying of new network services on demand. The central plane also acts as a single point of visibility, providing a coherent view of the operational characteristics for all the instances running on the appliance. This software-driven approach makes it possible to successfully support the dynamic changes inherent in today’s cloud-based, app-driven environment.

Benefits

Compared to the advancements in compute and storage virtualization, networking has fallen behind in fully realizing the promise of enterprise cloud computing. The dynamic nature of cloud services requires a new level of flexibility and scalability, which goes beyond the capabilities of today’s data center networks. Transitioning to software-defined networking (SDN) incorporates programmability and agility into your network, enabling it to keep pace with business demands.

Citrix Netscaler

Citrix NetScaler was created to transform traditional networks into next-gen, app-driven enterprises. Designed for use in virtualized networks, it’s ideally suited to integrate with SDN and cloud orchestration systems. The platform combines the flexibility of virtualization with the resiliency, reliability, and performance of purpose-built network appliances. Eliminating the need for multiple physical devices, a single Citrix NetScaler can be deployed in a multi-tenant environment, while also offering traffic isolation and dedicated resources per tenant.

Administrators can rightsize instances based on the workload required per tenant, with fine-grained control over the CPU, memory, and SSL hardware resources, to achieve performance goals.

Features

On demand cloud services and SDN allow organizations to quickly grow and transform to meet the demands of the modern workplace. Citrix NetScaler enables organizations to ensure the best security, performance and reliability whether workloads run in the data center or in an external cloud. By allowing IT to deliver every application workload at scale and with simplicity, organizations can benefit from all that cloud computing has to offer. Expanding the virtual network infrastructure portfolio.

Citrix and Cisco have delivered the Citrix NetScaler 1000V, a best in class application delivery controller that redefines Layer-4 and Layer-7 services. Building on Cisco strength in Unified Fabric and Unified Compute, and Citrix strength in intelligent, application delivery, the architecture runs on the Cisco Nexus Virtual Service Platform to provide a virtual network infrastructure that delivers scalability, elastic instantiation, and multi tenant operation, all with a common approach to service provisioning and management. The Citrix NetScaler 1000V is available via the normal Cisco sales and worldwide channels, providing a smooth migration path for Cisco ACE, GSS and CSS customers. Citrix NetScaler is the Cisco ACE replacement product recommended by Cisco.
