Not-for-proﬁt healthcare provider embarks upon cloud-ﬁrst IT strategy
As enterprise applications migrate from the corporate data centre to the cloud, it is becoming increasingly clear that private line connections, such as multiprotocol label switching (MPLS), are not built for internet-based environments. With the internet redeﬁning how businesses operate, companies are now realising that the opportunity to operate at ‘cloud speed’ is better served by integrating broadband services into the WAN transport mix.
One of those organisations is a leading not-for-proﬁt healthcare provider, Nuﬃeld Health, which 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, Nuﬃeld Health turned to Silver Peak to deploy SD-WAN.
The Initial Challenge
As an organisation with two data centres and around 20,000 users across more than 260 sites throughout the UK, Nuﬃeld Health was ﬁnding that its legacy MPLS WAN was struggling to connect its users to business-critical cloud-based applications. These included Software-as-a-Service (SaaS) applications such as TrakCare for Electronic Medical Records and Oﬃce365, as well as Infrastructure-as-a-Service (IaaS) applications including Microsoft Azure.
“As a not-for-proﬁt healthcare organisation with sites located across the UK, our staﬀ rely on data-critical applications to care for parents and our customers,” said Dan Morgan, IT operations director at Nuﬃeld Health. “We required a reliable WAN solution that would improve network performance and securely support our cloud-ﬁrst IT strategy.”
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. This was signiﬁcantly impacting network performance as a result. Ampito’s Managed SD WAN Service – RedSwan,, developed a WAN edge architecture that would intelligently and securely route WAN traﬃc over the internet based on application driven policies, without degrading performance.
In conjuction with RedSwan, Ampito selected the Silver Peak Unity EdgeConnect SD-WAN solution for its high performance and cost, as well as its ability to support seamless service chaining with zScaler and Palo Alto Networks ﬁrewalls for intelligent internet breakout, which will improve SaaS application performance, while keeping its branches secure.
As a result of the Silver Peak deployment, Nuﬃeld Health is now able to run dual internet links to its sites, with some sites able to run on 4G LTE for connectivity until its ﬁbre internet service is delivered. The company has reduced WAN traﬃc by up to 75 percent and saw a 4-6x increase in bandwidth. Unity Orchestrator – included with Unity EdgeConnect – and zero-touch provisioning, enabled a fast SDWAN deployment. Indeed, the company installed SD-WAN at 189 sites in just four months.
On average, this solution connected 15 sites per week, which peaked at 27 sites in one week. Nuﬃeld Health also deployed Unity Boost, an optional performance pack that can be used for speciﬁc sites if application performance degrades.
Using an in-house developed solution, Ampito has helped Nuﬃeld Health to reduce WAN traﬃc and increase bandwidth at sites across the UK in a matter of months. Nuﬃeld Health users now have access to business-critical SaaS and IaaS applications via the cloud and without impacting the performance of the network.
“We have been pleased with the positive impact on our network, and the speed of deployment was a massive bonus,” continues Morgan. “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.”
