Today’s Enterprise WAN Isn’t What It Used To Be

MARCH 13, 2023
For most enterprise NetOps teams, a discussion about the WAN is a discussion about the cloud. The WAN was how we got access to some websites and sent emails. Why do we need to create site-to-site VPNs or some sort of modern SD-WAN topology connecting all our branches when almost all traffic goes to the public internet and the cloud?

By implementing an MPLS alternative , an SLA-backed WAN and by eliminating the stacks of security appliances , bandwidth costs drop and operations become more efficient. And three WAN optimizers meant a one-time outlay of nearly $60,000 with annual renewals of $7,000. But when the protocol failed, so did the location.

At the core of NFV is the notion that network functions, such as SD-WAN , firewalling and secure web access, can be delivered as virtual appliances and run either on premises (vCPE) or at the carrier core data centers (hosted). Some VNFs, such as routers and SD-WAN, consume relatively few resources.
