Branch sites are ideal places to make networking simpler and less expensive. There’s often little or no IT expertise there, and it’s harder to justify costs because only a fraction of a company’s business happens at a given branch.
Yet the rise of software-defined WANs and branch offices, designed to scale back the expense and complexity of far-flung networks, has left some parts of the problem unsolved, according to SD-WAN startup Versa Networks.
For one thing, replacing branch appliances for each function with applications running on one system may raise software compatibility issues that are even more complicated than wiring up several boxes. Also, swapping out private WAN links for lower-priced internet service can open branches up to some new security threats.
