Los Angeles-based AIDS Healthcare Foundation (AHF) is a global organization providing cutting-edge medicine and advocacy to more than 200.000 patients in 28 countries. AHF is the largest provider of HIV/AIDS medical care in the U.S with 70 branches located in various states.
AHF has a main datacenter at their headquarters in California and a secondary datacenter for disaster recovery in Florida. The network is based on a hub-and-spoke model providing hosted MPLS services from the main datacenter to all the branch offices. The Internet is delivered via MPLS using 1,5 Mbps pipes from the datacenter to the branches. AHF is also a major user of XenApp and XenDesktop 6,0. “We wanted a robust global Layer 7 load balancing solution to ensure 24x7 availability of web servers between our datacenters. In addition, we needed to efficiently manage the bandwidth usage and utilize QoS to prioritize ICA and VoIP traffic in the small pipes between the datacenter and the branch offices,” says Art Kirakosyan, senior IT manager of datacenter operations at AHF.
In 2006 -2007, AHF installed two NetScaler MPX 5500s, one for each of their datacenters to provide global load balancing of web servers. For WAN traffic optimization AHF reviewed and conducted proof of concept (POC) on Riverbed Steelhead and Citrix CloudBridge. En la POC, los productos de Citrix ofrecieron una mejor optimización y priorización tanto del tráfico de ICA como de VoIP que Riverbed Steelhead.
“We selected and implemented two Citrix CloudBridge 3000s to complement the two Citrix Repeater 8820s and four Repeater 8540s already at our two datacenters. For traffic optimization at our branch offices we had implemented 20 Branch Repeater 300s,” says Kirakosyan.
NetScaler MPX appliances are high-performance; hardware-based solutions that provide industry-leading web application delivery and load balancing. They also enable a full-service delivery fabric that spans enterprise datacenters and cloud infrastructures to make applications and cloud services run five times faster. Todos los dispositivos NetScaler MPX admiten la tecnología Citrix nCore, que permite a los clientes aprovechar los sistemas de CPU multinúcleo para obtener un rendimiento de varios gigabits y una gran capacidad de ampliación para todas las cargas de trabajo de entrega de aplicaciones. Flexible pay-as-you-grow licensing helps customers protect their investments, avoid costly hardware upgrades and reduce the overall cost of ownership. NetScaler MPX appliances support small enterprises, massive global websites and everything in between.
The Citrix® CloudBridge family now represents the merging of the CloudBridge, Repeater and Branch Repeater platforms into a unified platform that accelerates applications across public and private networks to provide superior application performance and end user experience. CloudBridge offers a broad base of features including protocol acceleration support, market-leading VDI acceleration for Citrix® XenDesktop, secure and optimized between clouds and sophisticated quality of service (QoS).
By standardizing on CloudBridge WAN optimization at their datacenters and branch offices, AHF was able to reduce bandwidth usage and expenses by 50%.
By providing a granular logging of bandwidth utilization and a QoS engine, CloudBridge enables AHF to prioritize ICA and VoIP traffic over regular Internet traffic.
Citrix NetScaler and CloudBridge provide the best end user experience by accelerating the performance of web applications, XenApp and XenDesktop and also by providing a single point of support for both products.
“Currently, we are exploring CloudBridge Plug-ins for providing acceleration anywhere for our smaller branch offices and remote users. Also, NetScaler App Firewall for our web servers is a feature we might evaluate.” Kirakosyan said.
