Posts about Virtualization

Software-defined WAN (SD-WAN) got its start as a way for end users to save money. SD-WAN let users create their own virtual private networks (VPNs) using low-cost broadband connections. Users quickly learned that being their own network operator brought a lot of unwanted complexity and headaches. Now, these same enterprises are asking service providers to offer managed SD-WAN services ...

The benefits of moving towards a virtualized environment have been well publicized – eliminating vendor dependence and product obsolescence, faster introduction of new products and services, and the creation of a flexible, user-driven, on-demand service delivery environment that enables network functions to be dynamically defined, deployed and reassigned to match and organizations scale, performance and capabilities requirement ...

Software-defined WAN (SD-WAN) offers enterprise users a way to implement virtual private networks (VPNs) at a much lower cost than today’s operator-managed Multiprotocol Label Switching (MPLS) VPNs. However, today’s SD-WAN solutions put the enterprise in charge of all aspects of the network, including local access and backbone transport. That may be too much of a management burden to take on for already-overloaded IT departments ...

Travis told me that innovation efforts at Level 3 are aimed to increase operational scale and customer control by expanding the use of automation, as opposed to focusing specifically on SDN and/or NFV. “Whether the resource is physical or virtual, for us the heavy investment is on what orchestrates and controls all those elements,” he noted. “We didn’t have a focus on architecture, engineering or operations by themselves. Instead we worked across the groups. We found folks who came out of those backgrounds to be our innovation leaders ...
