Network-as-a-Service: A modern solution to today’s networking challenges

Traditional networking architectures over the past two decades or so prescribe that the hub of the network be build around a specific location, such as a data center or a company’s headquarters building. This location houses most of the equipment for compute, storage, communications, and security, and this is where enterprise applications are traditionally hosted. For people in branch and other remote locations, traffic is typically backhauled to this hub before going out to other locations, including to the cloud.

Though that formula has been standard operating procedure for many years, it doesn’t fit the way of work for many enterprises today. For one thing, there has been a major migration to the cloud. Those enterprise applications that run the business are now hosted in cloud platforms such as Amazon Web Services or Microsoft Azure, either as private applications or as SaaS apps such as Office 365 and Salesforce. In fact, companies often use multiple cloud platforms these days.

As for employees, more of them are now mobile or remote workers, but they still need secure access to enterprise applications and resources. The typical solution for giving mobile employees access to IaaS or PaaS resources is a VPN, which can be cumbersome and expensive to deploy.

These trends of cloud migration and mobility are only continuing to grow, and they are putting tremendous pressure on traditional networks. The old perimeter of network security is long gone. Unfortunately, the need for network security is stronger than ever as threats become more pervasive and damaging.
