By using software to control the wide area network (WAN), software-defined WAN (SD-WAN) solutions simplify WAN network management.
Moreover, application performance is improved with the addition of dynamically routed application traffic and application-aware routing, while security is enhanced with real-time access control and application-aware policies.
The following six case studies highlight how organizations in various industries have benefited from the implementation of SD-WAN solutions:
Michelin is the world leader in research and development for high-tech tires used on all types of vehicles.
With a need to support more than 120,000 employees in 170 countries, Michelin has the responsibility to provide efficient and reliable IT and network services.
Wanting to migrate from an existing WAN solution that used a dual MPLS link, Michelin was concerned about being dependent on local providers to deliver the necessary bandwidth. They were also facing complaints from users globally over the poor performance of business applications and audio/visual (A/V) communications.
Michelin chose VMware SD-WAN to achieve their objective of being able to directly manage and improve the quality of their IT network services.

2. OpenEye Scientific
OpenEye Scientific is a software development firm focused on assisting drug discovery and design.
With products designed for scientific rigor, speed and scalability are critical aspects of their IT infrastructure.
Faced with cost-prohibitive upgrades to networking hardware, OpenEye Scientific needed to find a solution that could adequately support the work being done by the computational chemists, medicinal chemists, and synthetic chemists using their software.
When OpenEye Scientific released their cloud-native drug design application using Amazon Web Services (AWS), they needed an affordable, reliable, and fast way for customers to connect to the platform.
The solution came with SteelConnect, which offered quick setup, easy centralized administration, and infinite scalability without hardware limits or other frustrations.

5. Rodericks Dental
Rodericks Dental operates 100 practices across the U.K., with over 650 employees, making them the third largest dental group in the region.
Rodericks Dental needed a network infrastructure that could provide continuous data center connectivity, protect patient data, and improve network traffic visibility with simple management command and control.
With an inexpensive existing solution, Rodericks Dental struggled with inefficient daily tasks and operations, difficulty troubleshooting issues, and the inability to scale as the business grew.
“We tried and tested a bunch of different solutions. Most weren’t stable enough to meet the requirements for operating a combined IT security and WAN solution in a lean IT environment,” says Alex Snell, head of IT, Rodericks Dental.
After evaluating the Barracuda CloudGen Firewall and SD-WAN solution, Snell was confident they would have the functionality they needed to support their needed IT security and network infrastructure for years to come.
