VMware and VeloCloud announce their networking and security strategy

It’s been a few months since VMware closed its acquisition of VeloCloud, a prominent SD-WAN provider. In that time, the two companies have worked to integrate their products, and recently they announced a unified strategy called the Virtual Cloud Network.The strategy fully supports the migration of applications and data out of the enterprise data center to the cloud and to branches — and with IoT, pretty much anything can be considered a branch today, as VeloCloud claims to have a customer with ocean-going ships as branches. The result is that many enterprises are in a position where their applications are everywhere, and their data is everywhere. This has profound implications on the network that needs to support all of this.To read this article in full, please click here READ MORE HERE…

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.[ Don’t miss customer reviews of top remote access tools. | Get daily insights by signing up for Network World newsletters. ]To read this article in full, please click here READ MORE HERE…

How to eliminate the default route for greater security

If portions of enterprise data-center networks have no need to communicate directly with the internet, then why do we configure routers so every system on the network winds up with internet access by default?Part of the reason is that many enterprises use an internet perimeter firewall performing port address translation (PAT) with a default policy that allows access the internet, a solution that leaves open a possible path by which attackers can breach security.+Also on Network World: IPv6 deployment guide; What is edge computing and how it’s changing the network?+To read this article in full, please click here(Insider Story) READ MORE HERE…
