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

Technology Short Take 91

Welcome to Technology Short Take 91! It’s been a bit longer than usual since the last Tech Short Take (partly due to the US Thanksgiving holiday, partly due to vacation time, and partly due to business travel), so apologies for that. Still, there’s a great collection of links and articles here for you, so dig in and enjoy.

Networking

  • Amanpreet Singh has a two-part series on Kubernetes networking (part 1, part 2).
  • Anthony Spiteri has a brief look at NSX-T 2.1, which recently launched with support for Pivotal Container Service (PKS) and Pivotal Cloud Foundry, further extending the reach of NSX into new areas.
  • Jon Benedict has a brief article on OVN and its integration into Red Hat Virtualization; if you’re unfamiliar with OVN, it might be worth having a look.
  • sFlow is a networking technology that I find quite interesting, but I never seem to have the time to really dig into it. For example, I was recently browsing the sFlow blog and came across two really neat articles. The first was on RESTful control of Cumulus Linux ACLs (this one isn’t actually sFlow-related); the second was on combining sFlow telemetry and RESTful APIs Continue reading

Installing the Azure CLI on Fedora 27

This post is a follow-up to a post from earlier this year on manually installing the Azure CLI on Fedora 25. I encourage you to refer back to that post for a bit of background. I’m writing this post because the procedure for manually installing the Azure CLI on Fedora 27 is slightly different than the procedure for Fedora 25.

Here are the steps to install the Azure CLI into a Python virtual environment on Fedora 27. Even though they are almost identical to the Fedora 25 instructions (one additional package is required), I’m including all the information here for the sake of completeness.

  1. Make sure that the “gcc”, “libffi-devel”, “python-devel”, “openssl-devel”, “python-pip”, and “redhat-rpm-config” packages are installed (you can use dnf to take care of this). Some of these packages may already be installed; during my testing with a Fedora 27 Cloud Base Vagrant image, these needed to be installed. (The change from Fedora 25 is the addition of the “redhat-rpm-config” package.)

  2. Install virtualenv either with pip install virtualenv or dnf install python2-virtualenv. I used dnf, but I don’t think the method you use here will have any material effects.

  3. Create a new Python virtual environment with Continue reading

Bridging Object Storage And NAS In The Enterprise

Object storage may not have been born in the cloud, but it was the major public cloud providers like Amazon Web Services, Microsoft Azure, and Google Cloud Platform that have been its biggest drivers.

The idea of object storage wasn’t new; it had been around for about two decades. But as the cloud service providers began building out their datacenters and platforms more than a decade ago, they were faced with the need to find a storage architecture that could scale to meet the demands brought on by the massive amounts of data being created, and as well as the …

IDG Contributor Network: 5 top data challenges that are changing the face of data centers

Data is clearly not what it used to be! Organizations of all types are finding new uses for data as part of their digital transformations. Examples abound in every industry, from jet engines to grocery stores, for data becoming key to competitive advantage. I call this new data because it is very different from the financial and ERP data that we are most familiar with. That old data was mostly transactional, and privately captured from internal sources, which drove the client/server revolution. New data is both transactional and unstructured, publicly available and privately collected, and its value is derived from the ability to aggregate and analyze it. Loosely speaking we can divide this new data into two categories: big data – large aggregated data sets used for batch analytics – and fast data – data collected from many sources that is used to drive immediate decision making. The big data–fast data paradigm is driving a completely new architecture for data centers (both public and private).To read this article in full, please click here

On the Leading Edge – Cloudflare named a leader in The Forrester Wave: DDoS Mitigation Solutions

On the Leading Edge - Cloudflare named a leader in The Forrester Wave: DDoS Mitigation Solutions

Cloudflare has been recognized as a leader in the “Forrester WaveTM: DDoS Mitigation Solutions, Q4 2017.”

The DDoS landscape continues to evolve. The increase in sophistication, frequency, and range of targets of DDoS attacks has placed greater demands on DDoS providers, many of which were evaluated in the report.

This year, Cloudflare received the highest scores possible in 15 criteria, including:

  • Length of Implementation
  • Layers 3 and 4 Attacks Mitigation
  • DNS Attack Mitigation
  • IoT Botnets
  • Multi-Vector Attacks
  • Filtering Deployment
  • Secure Socket Layer Investigation
  • Mitigation Capacity
  • Pricing Model

We believe that Cloudflare’s position as a leader in the report stems from the following:

  • An architecture designed to address high-volume attacks. This post written in October 2016 provides some insight into how Cloudflare’s architecture scales to meet the most advanced DDoS attacks differently than legacy scrubbing centers.

  • In September 2017, due to the size and effectiveness of our network, we announced the elimination of “surge pricing” commonly found in other DDoS vendors by offering unmetered mitigation. Regardless of what Cloudflare plan a customer is on—Free, Pro, Business, or Enterprise—we will never terminate a customer or charge more based on the size of an attack.

  • Because we protect over 7 Continue reading

Worth Reading: The Future is Conversational Systems

It’d be difficult to downplay the impact Amazon Web Services has had on the computing industry over the past decade. Since launching in 2006, Amazon’s cloud computing division has become the set the pace in the public cloud market, rapidly growing out its capabilities from the first service – Simple Storage Service (S3) – it rolled out to now offering thousands of services that touch on everything from compute instances to databases, storage, application development and emerging technologies like machine learning and data analytics. —Jeffery Burt @ The Next Platform

IDG Contributor Network: ROI linked to later stages of Industrial IoT

When most people think about the adoption of the IoT, they think about smart cities, autonomous vehicles, or the latest consumer tech and wearables. However, some of the most amazing technology applications are taking place within industrial verticals such as manufacturing, oil and gas (O&G), and transportation. Unfortunately, when asked about the state of IoT adoption within these markets, we’re often left relying on basic information about connected endpoints, instead of truly understanding how businesses are progressing through IoT maturity within the industrial field. To help answer these questions (and get a bit more in the weeds on the topic) my company, Bsquare, recently conducted its first Annual Industrial IoT (IIoT) Maturity Study. We polled 300 respondents at companies with annual revenues in excess of $250 million. Participants were evenly divided among three industry groups (manufacturing, transportation and O&G) and titles covered a wide spectrum of senior-level personnel with operational responsibilities, most of whom had spent an average of six years in their organizations.To read this article in full, please click here

Introduction to OVN and Red Hat Virtualization

Hi Folks, recently my friend and colleague, Tony James prepared and delivered an excellent webinar internally at Red Hat on how to configure Open Virtual Networking (OVN) in Red Hat Virtualization. For those of you that are unfamiliar with OVN, or what it offers, allow me to provide you with the proper illumination.

Background

Way back in the dark ages, the only way that mere mortals could get encapsulation, segmentation, and other benefits of SDN in RHV was via third party integration. Or if there was an OpenStack deployment that could be tapped into via the RHV Neutron integration. Recently though, native SDN (via OVN) is in Tech Preview in RHV 4.1, and I’m going to spend the next few posts going over the basics.

NOTE – Tech Preview is Red Hat’s way of providing the software bits for folks to try out, but there is no support for software in Tech Preview. The official statement is here. In short, the more interest and bugs filed against Tech Preview, the sooner it gets put in production.

The current fully supported virtual networking in RHV is built around “Linux Bridging”. It’s solid and it’s simple. That is to say that Continue reading

IDG Contributor Network: AWS re:Invent and the 5 fronts of the cloud arms race

For the last six years running, the most important event in cloud computing has been AWS re:Invent, where the market leader announces its latest improvements. This year, 44,000 people descended upon a very crowded set of Las Vegas venues spread across multiple hotels for breakout sessions, certification exams, a diverse expo floor, and the all-important keynotes where the newest offerings were announced.Increasingly, the public cloud arms race is being waged on four fronts, with a fifth quickly emerging. All five had a healthy set of announcements—here are some of the highlights.1. IaaS/PaaS AWS started the cloud revolution with its S3 object storage service in 2006, which was quickly followed by its EC2 compute offering and a set of other IaaS products. As time went by, PaaS services like load balancers, message queues, and databases emerged as key components as well. Both classifications of services are, of course, built on physical hardware that AWS organizes into availability zones and regions.To read this article in full, please click here
