IDG Contributor Network: ‘A (Networking) Christmas Carol’

Our story begins on a cold Christmas Eve in 1966, five minutes after my uncle stopped by our house to show off his new analog car phone. He worked for IBM at the time, and I can still remember him opening the door of his car Vanna White-style to reveal the status symbol inside.We’ve all been visited by old, curmudgeonly RF. As networking professionals, we know the joys of RF present, and there are enough predictions articles this time of year to get us excited about the future.If networking were A Christmas Carol, it might go something like this.The ghost of RF past The first of the RF spirits takes us to the 1980s, when cellular, WiFi and automotive connectivity were young and innocent. RF was so old you could see it, hanging in the air like a damp, grey fog.To read this article in full, please click here

IoT and the cloud: A match made in Seattle?

The recent AWS re:Invent conference in Las Vegas was all about the cloud, but another hot technology also played a leading role: the Internet of Things. In multiple keynotes, top Amazon Web Services (AWS) executives, including CEO Andy Jassy and CTO Werner Vogels, went out of their way to extol the virtues of IoT. The company also used the occasion to announce a slew of new IoT-related products.AWS’ IoT strategy Jassy spent time on IoT during the closing of his massive keynote speech (to be honest, though, he focused on just about everything at one point or another during his epic 2.5-hour presentation). But Jassy also addressed IoT during his relatively short segment of the earlier AWS Partner Summit keynote with Terry Wise, AWS Vice President of Global Alliances, Ecosystem and Channels. And Vogels talked IoT during his own keynote address.To read this article in full, please click here

Data ‘tsunami’ to absorb 20% of world electricity

It’s the "Dirty Cloud," says journalist John Vidal in a recent tweet. Vidal is referring to energy use by data centers, which he wrote about in an article for Climate Home News.In the story, published this week, the Guardian environment writer reveals a bleak picture of future global climate change emissions. Bleak, in part, because the discouraging projections he writes of are caused not by, as one might expect, fossil fuel power plants and internal combustion engine users, but by communications and data center power use.To read this article in full, please click here

How to squeeze the most out of Linux file compression

If you have any doubt about the many commands and options available on Linux systems for file compression, you might want to take a look at the output of the apropos compress command. Chances are you'll be surprised by the many commands that you can use for compressing and decompressing files, as well as for comparing compressed files, examining and searching through the content of compressed files, and even changing a compressed file from one format to another (i.e., .z format to .gz format).You're likely to see all of these entries just for the suite of bzip2 compression commands. Add in zip, gzip, and xz, and you've got a lot of interesting options.To read this article in full, please click here

VeloCloud and Aryaka in a two-horse race for SD-WAN leadership

Research firm IHS Markit recently released its Data Center Network Equipment market tracker report for Q4 2017 by analyst Cliff Grossner, which includes Software-Defined WANs (SD-WAN). I don’t normally comment on other industry research, but I have tremendous respect for Grossner, and his quantitative numbers are among the best. So, I felt a deep dive into his findings on the SD-WAN market was worth the effort.Also read: Why 2018 will be the year of the WAN It’s important to note that Grossner’s numbers include SD-WAN appliance and control management software revenue and not services, so his numbers will be smaller than other firms, such as IDC, which has the market pegged somewhere in the billion-dollar range. Neither is better than the other, per se; they’re just different.To read this article in full, please click here

Aerohive SD-WAN solution simplifies management of multi networks

Most people think of Aerohive Networks as a Wi-Fi vendor, which makes sense given most of the company’s revenue comes from selling wireless access points into businesses. In actuality, Aerohive is a cloud management vendor that has applied its expertise in that area to wireless LANs. About year ago, the company introduced its software-defined LAN (SD-LAN) solution that includes wireless APs and wired switches, enabling its customers to manage the entire campus network from the cloud.This week, Aerohive extended its reach into the WAN with the release of its SD-WAN solution that can be managed through HiveManager, the same cloud management tool used for its SD-LAN products, giving customers a single console for managing the WAN, wired network and wireless APs.To read this article in full, please click here

Arista brings the benefits of leaf-spine to routing

About a decade ago almost all data centers were built on a traditional three- (or sometimes more) tier architectures that used the spanning tree protocol (STP). That prevented routing loops but also deactivated all the backup links, which accounted for almost half the ports in large environments. This caused organizations to significantly overspend on their networks.Leaf-spine networks, on the other hand, have only two tiers, are much flatter and use something called ECMP (equal cost multi-pathing). So all routes are active, creating a much more efficient network that more agile and costs less.Also on Network World: 10 Most important open source networking projects The traditional three-tier data center was designed to scale up, which was the key requirement in the client/server era. Leaf-spine is optimized for rapid scale out, which has become critical in data centers today, as more and more traffic is moving in an East-West direction. To read this article in full, please click here

The results of the survey identified the following top four drivers for deploying an enterprise SD-WAN solution:To read this article in full, please click here

IDG Contributor Network: Linux then, and why you should learn it now

The booming popularity of Linux happened around the same time as the rise of the web. The server world, once proprietary, eventually fell in love with Linux just the same way networking did. But for years after it began growing in popularity, it remained in the background. It powered some of the largest servers, but couldn’t find success on personal devices. That all changed with Google’s release of Android in 2008, and just like that, Linux found its way not only onto phones but onto other consumer devices.The same shift from proprietary to open is happening in networking. Specialized hardware that came from one of the “big 3” networking vendors isn’t so necessary anymore. What used to require this specialized hardware can now be done (with horsepower to spare) using off-the-shelf hardware, with Intel CPUs, and with the Linux operating system. Linux unifies the stack, and knowing it is useful for both the network and the rest of the rack. With Linux, networking is far more affordable, more scalable, easier to learn, and more adaptable to the needs of the business.To read this article in full, please click here

Large enterprises abandon data centers for the cloud

Sure, it was a cloud computing conference, and maybe the goal remains a bit unrealistic, but at AWS re:Invent in Las Vegas last week, the number of enterprises expressing a wish to stop running their own data centers was too big ignore.Even old-line enterprises companies said they weren’t content to create a foothold in the cloud and stay with a hybrid cloud environment, though that’s the situation many currently find themselves in. No, many are looking to exit the data center business entirely, just as soon as they can manage it.Also on Network World: How a giant like GE found a home in the cloud And from the size and quality of the companies signing on to this stretch goal — think PG&E, Expedia, and to some extent even Goldman Sachs — it seemed clear that they represent only the tip of the iceberg.To read this article in full, please click here

Dell EMC makes big hyperconverged systems push with new servers

Dell EMC is expanding its hyperconverged infrastructure portfolio with new systems built around 14th generation PowerEdge servers.Converged (CI) and hyperconverged infrastructure (HCI) is a fancy way of saying turnkey systems with compute, storage, networking and software all combined into a single bundle. Rather than building a system from a variety of vendors, the customer gets everything they need from one vendor and it comes pre-configured to run out of the box.It’s basically a page out of the mainframe book, when everything came from one vendor (usually IBM). As server technology moved away from big iron and the x86 market took over, pieces were fragmented. You got your servers from Dell, HP or IBM, storage from EMC or NetApp, networking from Cisco or 3Com, etc.To read this article in full, please click here

IDG Contributor Network: To thrive in a digital age, businesses must look beyond log data

With the amount of data in the world predicted to increase at least 50 fold between 2010 and 2020, how we store that data has come into sharp focus. Collecting large volumes of raw log data from multiple applications and infrastructure components and sending it to a central location for storage and processing, for example, increases the size and cost of storage. And as the volume of data grows and storage and processing costs increase dramatically, businesses risk undermining the advantages big data brings. Furthermore, the surging demand for data has environmental implications; by 2020, 12 percent of the world’s energy consumption will be taken by our digital ecosystem, and this is expected to grow annually at approximately 7 percent until 2030. To read this article in full, please click here
