非营利性英国医疗保健提供商具有可靠的，有弹性的SD-WAN的网络性能明显更高

A leading not-for-profit healthcare provider, Nuffield Health was experiencing challenges with the impact its legacy MPLS WAN was having on the performance of its network. Since the company wanted to embark upon a cloud-first IT strategy, the company turned to SD-WAN.

Dan Morgan, IT Operations Director at Nuffield Health, explains, "As a not-for-profit healthcare organisation with sites located across the UK, our staff rely on data-critical applications to care for patients and our customers. We required a reliable WAN solution that would improve network performance and securely support our cloud-first IT strategy."

Routing Traffic With Application-Driven Policies

作为一个拥有两个数据中心和大约20,000个用户的组织，在英国的260多个站点中，Nuffield Health发现其传统MPLS WAN正在努力将其用户与基于业务关键的云的应用程序联系起来。其中包括软件即服务（SAAS）应用程序，例如电子病历和Office365的Trakcare，以及基础架构 - AS-A-Service（IaaS）环境，例如Microsoft Azure。

Following a review of its WAN usage, Nuffield Health found that more than 60 percent of its WAN traffic was already being backhauled to the internet, rather than to its two data centres, which was negatively impacting network performance.

因此，Nuffield Health通过其合作伙伴Ampito（技术解决方案的领先提供商Ampito）转向了Aruba（以前是银峰），用于Wan Edge Architecture，它将根据应用程序驱动的政策巧妙而安全地将WAN交通巧妙地驶入WAN流量，而没有应用程序驱动的政策，降解性能。

Brings High Performance and Cloud Security

Nuffield Health selected theAruba EdgeConnectSD-WAN edge platform for its high-performance and favourable cost, as well as its ability to support seamless service chaining withZScaler和Palo Alto Networksfirewalls for intelligent internet breakout, which will improve SaaS application performance while keeping its branches secure.

The阿鲁巴编排管理控制台 - 包含在EDGECONNECT平台中 - 零触摸配置可实现快速的SD-WAN部署。确实，该公司在短短四个月内就在189个站点安装了SD-WAN。平均而言，它每周连接15个站点，一周内达到27个地点。

Nuffield Health还部署了可选的Aruba BoostWAN optimization performance pack, which is unified on the EdgeConnect platform and can be used for specific sites if application performance degrades.

Nuffield Health users now have access to business-critical SaaS and IaaS applications via the cloud and without impacting the performance of the network.

Network Intelligence Proves Critical to Business

随着Aruba SD-Wan的部署，Nuffield Health现在能够运行双Internet链接到其站点，有些站点可以在4G LTE上运行，直到提供其光纤互联网服务为止。该公司的WAN流量减少了75％，带宽增加了4-6倍。

"We have been pleased with the positive impact on our network, and the speed of deployment was a massive bonus," Morgan concludes. "We now have visibility and control into our network, meaning we can see how SaaS and IaaS is being used. This level of cloud intelligence is critical to our organisation as we continue to embrace new healthcare technologies available in the market."
