When we first started evaluating SD-WANs, the market was pretty straightforward. You had a few appliance (virtual and hardware) providers, a service provider and that’s about it. Today, more than 30 vendors deliver some kind of SD-WAN.Mind boggling? A bit, but we can help. There are three categories of SD-WAN offerings today. You can buy SD-WAN equipment (and software) and do it yourself (DIY), subscribe to an over-the-top (OTT) SD-WAN service, or have your SD-WAN bundled with a carrier network, such as MPLS or Direct Internet Access (DIA). We’ll look at each one of them.To read this article in full or to leave a comment, please click here
That SD-WANs will replace routing was not the most important message from last week’s Gartner webinar with Gartner vice president and distinguished analyst Joe Skorupa.No, the biggest message came in some startling statistics. Half the market revenue is held by just two startups, which begs the question: With 30-plus vendors in the SD-WAN space, are you sure the SD-WAN vendor you’re considering has the cash for the long haul?No more routing
Back in September, we wrote about the argument for replacing routing with SD-WANs. It’s a message we've been thinking about for some time, listening to the frustrations of many of our enterprise customers. It’s also a trend that Skorupa's market data supports—and for good reason.To read this article in full or to leave a comment, please click here
Quick question, MPLS or SD-WANs, which would you say offers better performance? For the same bandwidth, we’d assume MPLS. After all, MPLS services are managed for a reason, right? However, as we learned on one recent project, internet performance has improved so much over the years that its performance can rival, even exceed, private WAN services.The situation
The project was with a manufacturing company that wanted to see if modernizing its MPLS WAN made sense. The alternative would be an SD-WAN or hybrid WAN.To read this article in full or to leave a comment, please click here
