SD-WAN has had a mixed reception over the years. A variety of factors have put this technology on a rockier market trajectory than some had expected. Now, with the rush to support Work- from Anywhere (WFA), it’s worthwhile to look at the strengths and weaknesses of SD-WAN and the role of end-to-end monitoring in making SD-WAN deployments better. SD-WAN Rising...

When Gartner first introduced the concept of “secure access service edge” (SASE, pronounced sassy) into the enterprise IT lexicon back in August 2019, they had estimated that “by 2024, at least 40 percent of enterprises will have explicit [SASE] strategies,” up from less than 1 percent in 2018. Flash forward to today, and not even Gartner could’ve predicted the smorgasbord...

Prior to the global pandemic, SD-WAN was among the leading digital transformation initiatives in the enterprise space, as IT teams deployed this tech to help to connect their increasingly distributed remote office footprint. Months into the global quarantine, however, it’s becoming increasingly clear that the pre-COVID focus on the remote office has shifted markedly to support work-from-home (WFH), which conventional...

The impact of the global pandemic has been dramatic for the enterprise space, upending financial forecasts and sending workers across the globe home in accordance with social distancing guidelines. But while the conversation regarding the workforce has largely been centered around ongoing work-from-home (WFH) initiatives, businesses are now emerging from the “rushed” phase of their transformation and into a period...

It’s safe to say that many 2020 enterprise networking priorities have been upended as a result of the COVID-19 outbreak. But once the dust settles on the impromptu, quarantine-motivated digital transformations enterprise IT recently undertook, teams will need to reexamine many of the larger-scale IT projects that were on their plate before global events took the wheel. Network World’s recently...

Not only are branch offices growing in number as enterprises ramp up decentralization, but so is the data being generated at the branch and where that traffic goes. With IaaS and SaaS transforming how apps are delivered to branch locations, these offices are increasingly connecting to both cloud providers and their corporate data centers (if not retiring their dependency on...

In an industry where acronyms and initialisms are a dime a dozen, few tech terms are as ubiquitous in the world of enterprise networking as MPLS and SD-WAN. Sure, SaaS, PaaS, IaaS and UCaaS represent buzzworthy new workflows that have changed how enterprise IT teams are managing their tech footprints. But when it comes to the underlying networks that support...

While SD-WAN has been trending in the enterprise IT space for a few years now, there’s been little official consensus on what these solutions should encompass, let alone what defines a “best-of-breed” SD-WAN. Sure, the label SD-WAN has been marketed publicly by many providers, but in lieu of a standard that defines what exactly these tools should deliver, customers may...

Enterprise IT and network ops teams may not appear to have much in common with the names on your NCAA March Madness bracket. But in both arenas, teams need to be masters of strategy, cooperation, and fast thinking in order to succeed. That’s because just like college basketball, network monitoring and management requires having both a strong offense and defense....

There’s no denying that the SD-WAN market is having a moment. After sliding into the Trough of Disillusionment on the 2017 Gartner Hype Cycle, SD-WAN was firmly on the Slope of Enlightenment for 2018, and continues to build both momentum and advocacy as the decade comes to a close. What’s attractive about SD-WAN is that it doesn’t force teams to...

Before the days of personal computing -- and well before the dawn of smart devices -- it was easier for the relatively few users leveraging the Internet to recognize familiar IP addresses, like memorizing a home phone number in the pre-caller ID days. While we may type URLs into search bars and click “Send” on email, computers don’t actually read...

Just last summer, we published a post that discussed the differences between SD-WAN and WAN optimization. At the time, many people were simplifying the discussion and wondering if SD-WAN could replace aging WAN optimization solutions. When you break down the purposes of each technology, the two look more like a dynamic duo than a replacement for one another. But times...

SD-WAN was originally designed to be the successor technology to MPLS networks, but it doesn’t appear to have worked out that way. Research from Nemertes has shown that nearly 80% of companies with a pre-existing MPLS deployment retain the technology after SD-WAN adoption. Clearly there is some synergy between SD-WAN and MPLS. How does an older technology co-exist with a...

Which approach is your company taking with MPLS? This breakdown covers the various use cases that might drive the SD-WAN vs. MPLS decision. Remote locations with a lot of streaming business-critical applications (VoIP call centers, maybe) will still likely need MPLS to keep performance strong. But for cloud-driven companies, SD-WAN products that are cloud-enabled can be a win. As the...

We always like to hear the stories of those IT early adopters for a new technology. In this story, it’s several heads of IT who’ve adopted SD-WAN. For both, their companies needed a better way to provision and manage branch office infrastructure. For one, the Bay Club Company, using SD-WAN is actually helping IT drive revenue. Provisioning new locations is...

Either WAN optimization is dead, or it’s more important than ever. This story argues that WAN optimization reached its peak in the era of limited bandwidth. Now, though, the technology has lost its usefulness because it can’t improve VoIP or video streaming application performance. On the other hand, this analyst says that WAN optimization should be a no-brainer when using...

No one would blame you if you can’t muster up much enthusiasm for IPv6. After all, IPv6 has been “the future” of internet protocols since its inception in 1998, without much evidence it's happening. Even though you’ve been reading about the impending downfall of IPv4 since 2007, here we are in 2017 watching adoption just barely creep above 20%. You...

More healthcare organizations are discovering SD-WAN technology for help managing their many remote locations. It makes a lot of sense—in many ways, healthcare businesses like hospitals and home healthcare facilities are the poster children of the challenges of modern networking. Each remote office or location needs high-performing networks and applications, and most don’t have IT teams on site. We’ve heard...

A recent survey from Dimensional Research found that nearly all respondents are facing multiple WAN security and management challenges. Network complexity is the underlying challenge for most respondents, which they’re aware of, but not addressing. The top three challenges all involve supporting branch offices: Managing devices, mitigating security risks and deploying new solutions at branch offices. It’s not a surprise,...

Today, there is a lot of effort toward speeding up cloud-hosted app performance through the use of solutions like SD-WAN, but not enough attention afforded to the so-called last mile of these connections. This last mile is the final network step that gets data coming into a particular office to the user requesting that data. For IT teams managing any...

It may have seemed for a moment there that MPLS was on its way out as SD-WAN came onto the scene and businesses with remote locations used more public internet. That’s probably not the case, though. A recent Nemertes Research survey found that about 21% of organizations are deploying some kind of SD-WAN technology. Notably, though, they aren’t getting rid...

This week, Packet Pushers has some excellent guidance around avoiding short-term networking fixes for application issues—or, as they call them, “stupid network tricks.” The way to avoid those tricks, they say, is to get ahead of the problem by involving IT at the outset of every project. Instead of IT being a place to put blame and fight fires, they...
