Private cloud use grows, and ZeroStack wants to help spin them up
In June, private cloud infrastructure provider ZeroStack hired David Greene as its new CEO. For those of you who have followed the networking space closely, you may recognize Greene as the chief marketing officer of a couple of companies that were pioneers in their respective industries. Most recently, he was at Aerohive, one of the first Wi-Fi vendors to embrace a completely controller-less model.Prior to that, Greene was CMO of Riverbed. Riverbed certainly wasn’t the first WAN optimization vendor, but the company was responsible for evangelizing it and making it a household term (at least among IT circles).+ Also on Network World: Public vs. private cloud: Why the public cloud is a real threat to security + Now, Greene is trying to catch another wave, as ZeroStack is one of the first companies to offer an easy-to-deploy solution that enables businesses to quickly deploy a private cloud.To read this article in full or to leave a comment, please click here

Dell EMC flexes some HCI muscle at VMworld 2017
In the world of technology, August is normally a fairly quiet month, and overall it was—but not in the realm of hyper-converged infrastructure (HCI).Around mid-August, Cisco finally announced the long overdue acquisition of Springpath, indicating it sees a strong potential upside in this market. Also in August, VMware held its annual user event, VMworld, and at the event it and its closest technology partner, Dell EMC, made a significant amount of news in the area of HCI. Historically, HCI has been used for desktop virtualization, but recently the uses cases have expanded into other business critical areas. And last week, Dell EMC and VMware announced new joint solutions. To read this article in full or to leave a comment, please click here

Cisco’s IWAN isn’t dead
Earlier this month, Cisco completed the acquisition of SD-WAN vendor Viptela, which it had announced in early May.The companies’ recent news sparked several rumors about the fate of Cisco’s Intelligent WAN (IWAN), with publications writing such articles as “Is the End Near for Cisco’s IWAN?” and “Cisco’s Viptela acquisition could mean IWAN is dying or dead.” The content of the articles isn’t quite as aggressive as the headlines, but the articles have led to a number of misconceptions about what Cisco will do with its SD-WAN solution.To read this article in full or to leave a comment, please click here

Cumulus does container networking the right way
About a month ago, someone asked me to define the term “digital transformation.” At first, I thought about giving a long technical definition that mentioned the convergences of people, process and data, but then I shortened to one word — speed. Digital transformation is all about doing things faster than the competition. This is one of those things that’s easier to say than do. Most businesses simply can’t move faster just because they want to. Instead it requires an entirely new approach to IT. Gartner uses the term “Mode 2,” but other terms are things like agile development or DevOps. + Also on Network World: Adapting the network for the rise of containers + This new approach to IT has brought with it several new technologies, one of which is containers. The use of containers has steadily increased because IT departments can quickly spin them up, do whatever task they need to do and then shut them down. The whole process can be automated, so the IT organization doesn’t even need to be involved. To read this article in full or to leave a comment, please click here

Cisco buys Springpath, adds fuel to the HCI fire
Last December, I wrote a post looking at “What to expect from Cisco in 2017”. It’s a foregone conclusion that Cisco will make a number of acquisitions every year, so that’s not hard to predict. The tough part is guessing the potential targets.One of the easier acquisitions to predict was Springpath because Cisco’s HyperFlex hyper-converged infrastructure (HCI) solution is an OEM of Springpath. The two companies have been working very closely since Springpath was founded in 2012. The product has been extremely well received by customers and channel partners, resulting in a little more than 1,800 customers to date. In fact, nearly customer and channel partner wanted the companies to join. To read this article in full or to leave a comment, please click here

SDN: Technology to cut costs, speed new services
Software defined networking is defined by a decoupling of the control and packet-forwarding planes in a network, an architecture that can slash operational costs and speed the time it takes to make changes or provision new services.Since all the intelligence resides in software – not baked into monolithic specialty hardware – customers can replace traditional switches with commodity devices to save on capital costs. SDN also makes it possible for the network to interface with applications directly via APIs to improve security and application performance.So what is SDN? Traditional networks are made up of devices with integrated control and data-forwarding planes so each box needs to be configured and managed independently. Because of this, even simple changes to the network can take weeks or even months to complete because the changes have to be made to each device. This was acceptable when network changes were typically made independently from business changes.To read this article in full or to leave a comment, please click here

Expand Wi-Fi quickly, easily with Aerohive’s wall plate
In many industries, it’s critical to get Wi-Fi everywhere, but it can often be difficult accomplish this. For example, extending a hotel comprised of smaller cottage-type rooms or one with lots of suites has many hard to reach places with traditional access point (AP) placement. Dorm rooms or hospitals typically want Wi-Fi everywhere, but it’s often difficult to provision it because of interference from thick walls or other infrastructure. One possible solution is to put an AP in every room, but that can get prohibitively expensive given the cost of APs and the expense of running new cables to every location.Another option has been the growing number of “wall plate” APs where the existing wall plate is removed and an AP in the form factor of a wall plate is connected into the existing Ethernet cable, bringing Wi-Fi to that location.To read this article in full or to leave a comment, please click here

The new Extreme Networks is off and rolling
The story of Extreme Networks is one of the more remarkable turnarounds I’ve seen in technology in years. About two years ago the company had a market cap of under $300 million, and I thought they were a sure-fire acquisition target for someone who wanted some decent technology on the cheap — because it was becoming apparently clear that the once-cool networking company had lost its way like so many others before it.Many of the brand names we have known in the past — Nortel, 3Com, Cabletron, Lucent, FORE systems and Foundry — all dropped as Cisco got bigger and HP Networking gobbled up the low end. There just didn’t seem to be room for another vendor. If an acquisition happened, it would likely fall on the scrap heap that so many other networking vendors have been tossed on.To read this article in full or to leave a comment, please click here
