IDG Contributor Network: Internet of Things helps fuel growth of data lakes

Data lakes, storage repositories that hold extremely large amounts of raw data in its native format until the data is needed by users, are becoming increasingly popular within enterprises.Helping to fuel interest in data lakes are the digital transformation efforts underway at many enterprises, spurred by the emergence of the Internet of Things (IoT). The connected objects in the IoT will generate huge volumes of data.As more products, assets, vehicles and other “things” are instrumented and data ingested, it’s important that IoT data sets be aggregated in a single place, where they can be easily analyzed and correlated with other relevant data sets using big data processing capabilities. Doing so is critical to generating the most leverage and insight from IoT data.To read this article in full or to leave a comment, please click here

“The Internet is Home” – Youth voices on why we should keep the Internet on

Last year alone, the international digital rights advocacy organization Access Now recorded 56 Internet shutdowns worldwide. There's concern about this growing trend and worry that governments are blocking social media and communications tools, in particular.

Many private sector and civil society organizations have condemned the shutdowns, and there have been dialogues and campaigns held around the world to try and prevent this growing trend. But while most of these dialogues are filled with decision-makers, legislators, and civil society organizations, young voices have been left out.

How to quicken your site’s webpage load time

If you run a website of any significant size, odds are you utilize some form of content management system (CMS). Wordpress, Drupal, or the like.And, if you don’t use such a system, you probably employ rather extensive use of some form of server-side, scripted, page generation. PHP, ASP, Ruby… the list goes on and on.There are many scenarios where such a system makes a great deal of sense. But I’m here to tell you, right now, that it is highly unlikely that you actually need them… at least for the majority of your page. And, what’s more, if you migrate away from a CMS system you can not only make your webpages smaller and faster-loading for your visitors… but you can save significantly on your server infrastructure costs as well.To read this article in full or to leave a comment, please click here

Asymmetrical Traffic Flows and Complexity

One of my readers sent me a list of questions on asymmetrical traffic flows in IP networks, particularly in heavily meshed environments (where it’s really hard to ensure both directions use the same path) and in combination with stateful devices (firewalls in particular) in the forwarding path.

Unfortunately, there’s no silver bullet (and the more I think about this problem, the more I feel it’s not worth solving).

Video storage leads to hyperconvergence for law enforcement agency

Hyperconvergence wasn’t on Philip Lisk’s mind a decade ago, when the Bergen County Sheriff's Office started using technology from Pivot3 to store data from video surveillance cameras.“We were trying to store video in an IP world. That’s how we got to know Pivot3,” says Lisk, director of IT at the largest law enforcement agency in New Jersey’s Bergen County, which sits across the Hudson River from New York City. A 12-year veteran of the BCSO, Lisk supervises its networks and serves as the technical consultant to the entire county for video and data security.Well before the term "hyperconverged infrastructure" was coined, BCSO chose Pivot3 for its converged server and SAN solutions, engineered specifically for storing petabyte-scale video workloads. Yet as the technology matured over the last several years, and BCSO kept up with upgrades, the deployment evolved from a tactical video-centric project into an enterprise HCI platform that’s set to handle many of the agency’s IT workloads going forward, including its virtual desktop infrastructure (VDI).To read this article in full or to leave a comment, please click here

OpenStack and Cumulus Linux: A match made in networking heaven

A few weeks ago, we attended the OpenStack Summit where we had a wonderful time connecting with customers, partners and several new faces. With the excitement of the event still lingering, we thought this was a great time to highlight how OpenStack and Cumulus Linux offer a unique, seamless solution for building a private cloud. But first, here are a few highlights from the conference.

OpenStack Summit 2017, Boston

  • Jonathan Bryce, Executive Director at OpenStack Foundation, opened the show talking about the substantial growth of OpenStack over the past several years and how they are just one part of the vibrant open infrastructure community. A large focus of the conference was how organizations are moving towards private cloud environments as they realize it’s a better long-term solution.
  • Throughout the conference, containers and Kubernetes were the hottest topics. Many sessions throughout the four days focused on these technologies and how organizations are looking to use them as an abstraction layer to make infrastructure less visible or locked-in.
  • Edward Snowden was one of the most favorited speakers. Presenting from Russia, Snowden focused on how IT professionals are in position to influence how cloud infrastructure is built, influence the future of the internet Continue reading

PCIe versus Ethernet in a Composable System

I posted a link to a worth reading story last week about Liqid’s composable hyperconverged system. A reader (Vova Moki) commented on the LinkedIn post with this question—

Although I don’t understand how much faster is the PCIe than regular NICs?

Excellent question! It certainly seems that 100g Ethernet should be much faster than PCIe; this article lists the highest speed of PCIe as 15.8G/s across 16 lanes, with faster speeds expected into the future. Further, PCIe runs on parallel lanes, which means it must be very difficult to build a switch for the technology. The simplest way to build such a switch would be to pull the signals off the 16 different lanes, serialize them into a single packet of some sort, and then push them back out into 16 lanes again (potentially in different order/etc.).

So why should composable systems use something like PCIe, rather than using 100g Ethernet. After all, the Ethernet NIC is essentially doing precisely what a PCIe switch would need to do by pulling the data off a PCIe bus, serializing the data, and sending it over a network to a switch, which can, with the right design, already switch these packets Continue reading

Augury scoops up cash to power the industrial IoT

Ever since outgoing GE CEO Jeff Immelt opined upon his organization’s move from being an industrial machinery vendor to a software one, the world has been increasingly interested in the opportunities introduced by the industrial Internet of Things (IIoT).IIoT simply refers to the increasing trend towards industrial machinery being connected to the internet and pinging off all sort of interesting data that can then be monitored and analyzed. And while it is fair to say that connected industrial machinery has been around for a long time (via SCADA and PLCs), the difference today is that under the IIoT, it is general the public internet that has all this data traversing on it. Further, increasingly customers are looking to the IIoT to deliver efficiencies, create agility and reduce downtime.To read this article in full or to leave a comment, please click here
