As critical business applications are moving to the cloud and with the wide adoption of SaaS and mobile applications in the workplace, connectivity becomes a crucial business asset with the direct effect on the bottom line. Software-defined Wide Area Networks ( SD-WAN ) can get the job done. Here is why.

Most enterprise data networks are still optimized for a computing model in which the bulk of applications reside in the datacenter. Internet access remains tightly controlled, with only large, or headquarters facilities having local Internet connectivity. The answer?

After all, without the network, todays technology-powered businesses are dead in the water. The network doesnt have to be totally down, though, to disrupt the business. Slow or unpredictable application response time can cripple point of sale, customer service, manufacturing essentially every part of the business.

MPLS cost reduction is the target of the emerging SD-WAN market that is bustling with solutions looking to take the corporate wide area network to a whole new level. MPLS isnt encrypted by default: MPLS relies on the carrier private network for security because the data doesnt flow on the public Internet.

The global MPLS approach to networking works well if: The users are in fixed locations such as branch offices, The only corporate applications are hosted in-house, and Business needs dont change very often. Corporate applications are increasingly in the cloud. Clearly, an alternative is needed, but its not the public Internet.

Traditionally, Wide Area Networks (WANs) and network security were loosely coupled entities. Networking teams focussed on the connectivity between locations; security teams focussed on protecting against malware threats and other external or application-layer security issues.

I read with some surprise the interview with Zscalers CEO, Jay Chaudry, in CRN where he stated that the network firewalls will go the way of the mainframe, that the network is just plumbing and that Zscaler proxy overlay architecture will replace it with its application switchboard. This is my take. The proxy firewalls faded.

Weve been discussing the impact the dissolving perimeter has had on networking and IT. Rather than IT playing this kind of shell game on itself, IT should evaluate WAN architectures holistically and look at the quality of experience, availability, security, cost, agility, manageability, and extensibility of the network.
