Decoding SD-WAN for Enterprises

In the age of transformation, no building block of your Enterprise has been left untouched. Therefore, it has become an unavoidable reality that Businesses need to be equipped enough in order to cope up with the said transformations. Enterprises must continually evolve to stay relevant in today’s hypercompetitive environment. Companies across the globe turn to digital initiatives to help drive business, product or customer experience innovation. These digital initiatives can create complexities for IT organizations. And with the pace of change in today’s business, it’s a true challenge to keep up. You need a secure, agile and efficient network that you control.

Digital transformation continues to be the driver behind network refresh for Enterprises. Increasing bandwidth, cloud IaaS and SaaS applications along with WAN complexity and security are largely the same as in previous years, but these disruptions have evolved and are becoming increasingly important issues IT needs to solve across their networks and not just the WAN.

Digital Disruption. More devices, creating more data is challenging IT. How can IT manage more devices coming online when they lack business and IT insights into what is happening on the network.

Complexity. Branches contain multiple devices, this means IT has to make changes to each device separately and in most cases manually resulting in IT being slow and prone to errors.

Security. The number of security attacks continues at a relentless pace and attacks are becoming more sophisticated and coming from both inside and outside of networks and IT is having a hard time keeping up with an unconstrained attack surface.

For Enterprises SD-WAN offers the ease of deployment, central manageability and reduced costs that organizations seek to stay competitive while continuously improving the customer experience. SD-WAN is a new simplified and more effective way of deploying hybrid WAN solutions. At the center of SD-WAN, the controller continuously monitors the network path to detect problems before they affect applications, and dynamically routes traffic to a different path if required.

“The top perceived benefits of SD-WAN solutions relate directly to improvements in networking/connectivity, including better performance, improved scalability, and increased network agility. “ — Spiceworks Research Report

Why Organizations are Choosing SD-WAN
There days we see that there is both trend and necessity wherein the bulk data loads and applications are moving to the cloud, which in-turn creating ever-increasing traffic on company networks. As a result, IT decision makers are turning towards SD-WAN solutions to overcome latency and poor performance. In addition to improving performance and reliability, SD-WAN offers businesses the scalability to easily add bandwidth on-demand from existing broadband connections. Its more capable of centrally managing with the security features like UTMs, firewalls and application policies with the help of powerful software orchestration interface.

SD-WAN utilizes software to simplify the delivery of WAN services to remote locations, such as branch offices. It’s one of the reasons SD-WAN has become so popular among vertical markets with distributed locations, including retail and financial services. These types of businesses count on SD-WAN’s high bandwidth, low latency and exceptional reliability to keep their staff productive and their customers coming back.

“SD-WAN has emerged as one of the hottest topics in the WAN industry. It will become one of the key building blocks of network evolution, driving the flexibility, manageability, scalability, and cost effectiveness that organizations require in their balancing act between rapidly growing requirements and much flatter budgets.” — Jan Hein Bakkers, IDC

What Type of SD-WAN Solutions Will Help My Organization?
Organizations need SD-WAN solutions that are more than a software toolset. A solid SD-WAN solution should have the ability to dramatically enhance and accelerate an organization’s ability to procure and administer their corporate network. It should provide companies with a next-generation networking solution that can better utilize network connections, reduce costs and complexity, and increase both visibility and agility.

When selecting a provider for SD-WAN solutions, there are a number of issues to be considered, from technical capabilities to effective collaboration to support services.
So, it would be better to know that the Vendor’s SD-WAN have capability like:

  • Host and operate the cloud infrastructure
  • Manage the initial configuration of the system and appliances
  • Deploy updates and handle trouble tickets with 3rd party vendors
  • Let you take over control of the network when you’re ready
  • Path Selection
  • Routing Protocols
  • IPv6 Support
  • Overlay & Underlay Transport
  • Secure Multi-Tenancy
  • Handle all capacity management, release certification and upgrade management of infrastructure
  • Device Form Factor & Controller Location
  • Service Insertion & Chaining
  • Provide all of your network connections to efficiently manage bandwidth

And Vendor is flexible enough to cater User’s below requirements:

  • Lowering costs
  • Increasing agility to meet the more demanding connectivity of modern business networks
  • Keeping up with and taking advantage of Broadband innovations
  • Making a geographically-dispersed team more connected
  • Increasing usability and visibility into Cloud applications
  • Increasing network security
  • Resiliency
  • Integration into Existing Networks
  • Provisioning, Management & Reporting
