Software Defined WAN (Wide Area Network) is currently a hot topic in IT conference rooms across the globe. SDWAN is not a new topic or product for that matter. So why all the hype about SDWAN?
WHAT SD-WAN IS NOT…
To help understand what SDWAN is, let’s understand what an SDWAN isn’t. From the book Software-Defined WAN for Dummies published by John Wiley and Sons:
So now you have digested what SDWAN is not, let’s dig into what it is and they might explain the hype.
WHAT SD-WAN IS
SD-WANs are built virtually. This allows them to utilize different physical and transport media. They can also span different providers.
Separating the control plane from the data plane makes SD-WANs more abstract and flexible. Through this separation, securing the control plane is also easier.
SD-WAN affords interoperability between circuits, devices, and services. Interoperability also eases service delivery to new branches in the enterprise.
- COST EFFECTIVE
Cost savings comes from the ability to use cost-effective vendor-neutral network and system devices to build the SD-WAN. Every organization wants to save money!
- USAGE & PERFORMANCE MONITORING
SD-WAN allows for consolidation of monitoring systems to gain insight into usage and performance of your company’s WAN.
- VENDOR NEUTRAL
Another factor that is behind all the hype is the fact that SD-WAN supports open networking and interoperability. Check out ONF and ONUG the two groups that support open SDNs (Software Defined Networks)
SD-WAN is MSP (Managed Service Provider)-ready. That makes migrating to the cloud and offloading your workload to a MSP that much easier.
SUMMING IT UP
Software Defined WAN helps improve business agility as with any software-defined solution. Through automation and reliance on cloud IT efficiency is bolstered. With the prior too benefits overall cost reduction is easily achieved. I hope that this explains briefly, why there is so much hype about SD-WAN.
