Meeting the Challenges of Enterprise IT with SD-WAN

By: Abhey Dadwal, Senior Product Manager

As enterprise IT has become more sophisticated, it has also become more complex. Cloud adoption continues to rise, providing critical infrastructure, computing and a myriad of “as a service” cloud-based applications. Enterprises have become more geographically diverse to meet the needs of their local customers. More employees, customers and vendors are communicating via more types of devices, requiring different wired and wireless connections.

The result: wide area network management has also become infinitely more challenging. Enterprises often find that they have to use multiple WAN service providers and applications to assemble their WAN (wide area network), increasing management complexity and costs. Legacy WANs may not be providing the flexibility, capability, or security that your business needs to be fully connected and competitive.

According to a recent Dimensional Research global study, network managers identified six key challenges with enterprise IT:

  • Managing network and security devices at branch locations (52%)
  • Mitigating information security risks at branch locations (50%)
  • Deploying new network and security solutions at branch locations (42%)
  • Increasing costs due to the growing traffic volume over their MPLS network (42%)
  • Reducing the time it takes to bring up a new branch location (31%)
  • Providing fast access to cloud applications (SaaS) (25%)

Enterprise SD-WAN (Software-defined Wide Area Network) technology addresses the challenge of WAN management. SD-WAN enables enterprise customers to mix underlying access technologies, for example, IP-VPN and DIA, as part of a unified WAN solution — making the overall network more cost-effective. SD-WAN vendors have leveraged Network Function Virtualization to achieve a nimble and cost-effective network architecture allowing enterprises to deploy and manage the network in a cost-effective manner. Zero Touch Provisioning and remote management help in deploying new branch solutions quickly and efficiently. Overall, SD-WAN overcomes the evolving challenges faced by sophisticated enterprises by allowing multiple options and providing the flexibility to customize the solutions for each branch site based on the type of applications and usage.

Earlier this month, we were excited to debut Zayo’s new SD-WAN  solution. Our extensive fiber footprint, strong IP backbone and innovative Tranzact self-service application set us apart from other providers. Our solution is an extension of our robust portfolio of WAN solutions and deep experience with WAN implementations. The benefit for customers: full interoperability with our IP-VPN solution and multiple gateways with localized entry points. This enables enterprises to integrate diverse infrastructures, add new locations efficiently and cost-effectively and link to multiple cloud providers. Finally, we offer maximum flexibility for enterprises, with both self-service and managed options — and features including reporting and analytics and enhanced security.

Interested in learning more? SD-WAN has generated quite the buzz — but what can it really do for your enterprise? Join us as we take a more in-depth look at this solution in upcoming blogs.
