VMware jumps into SD-WAN with VeloCloud purchase

VMware today announced plans to acquire VeloCloud, one of the leading companies in the fast-growing software-defined Wide Area Network (SD-WAN) market.SD-WAN represents a new way to manage network connectivity to branch and remote offices using software-defined networking principles. Software-based SD-WAN offerings from companies like VeloCloud can aggregate multiple types of connections, including broadband, MPLS and cellular, to create more reliable connections that are often less expensive than a pure MPLS use. Research firm IDC predicts SD-WAN will be a more than $1 billion market this year, and grow at 69% to more than $8 billion by 2021.To read this article in full or to leave a comment, please click here

Reaction: Enabling Privacy is not Harmful

The argument for end-to-end encryption is apparently heating up with the work moving forward on TLSv1.3 currently in progress in the IETF. The naysayers, however, are also out in force, arguing that end-to-end encryption is a net negative. What is the line of argument? According to a recent article in CircleID, it seems to be something like this:

  • Governments have a right to asymmetrical encryption capabilities in order to maintain order. In other words, governments have the right to ensure that all private communication is ultimately readable by the government for any lawful purpose.
  • Standards bodies that enable end-to-end encryption that will prevent this absolute governmental good endanger society. The leaders of such standards bodies may, in fact, be prosecuted for their role in subverting government power.

The idea of end-to-end encryption is recast as a form of extremism, a radical idea that should not be supported by the network engineering community. Is end-to-end encryption really extremist? Is it really a threat to the social order?

Let me begin here: this is not just a technical issue. There are two opposing worldviews in play. Engineers don’t often study worldviews, or philosophy, so these questions tend to get buried in Continue reading

MINIX — The most popular OS in the world, thanks to Intel

Take a look at your desktop computer. What operating system is it currently running? Now take a look in your data center — at all of your servers. What operating system are they running? Linux? Microsoft Windows? Mac OS X? You could be running any of those three — or one of countless others. But here’s the crazy part: That’s not the only operating system you’re running. If you have a modern Intel CPU (released in the last few years) with Intel’s Management Engine built in, you’ve got another complete operating system running that you might not have had any clue was in there: MINIX. To read this article in full or to leave a comment, please click here

3 must-attend events at OpenStack Summit Sydney

OpenStack Summit Sydney is just around the corner, and Cumulus Networks wouldn’t miss it for the world! We’ll be there at our booth, doing daily contests and raffles, so make sure to stop by. If you’re lucky, you might walk away with a 6 pack of Linux Lager. But of course, you don’t need beer to have fun at OpenStack — there’s so much to keep you busy and fired up! With so many amazing panels and presentations, it’s hard to pick and choose which events to attend. Fortunately, we’ve done the research and picked out the top 3 must-attend activities. If you’re going to be at OpenStack in Sydney next week, make sure to check these out:

  1. 1-on-1 OpenStack demo: Eager to get hands-on with everything OpenStack has to offer? Then you should sign up for a live demo with Cumulus Networks! We will first be doing a theater session at 4:00 PM on Monday at the Marketplace Demo Theater Level 2, where CTO JR Rivers will give insight as to how production deployments are leveraging IP fabrics and OpenStack networking to simplify operations and deliver services at scale. But of course, nothing beats seeing the tech up-close and Continue reading

IDG Contributor Network: Cisco Aironet Developer Platform: a stealth IoT opportunity for developers

In mid-October, Cisco announced the launch of its Aironet Developer Platform (ADP), a third-party development platform based on the Aironet 3800 series access points (AP). While there was no mention of IoT in the announcement, this is a stealth IoT opportunity. While Cisco’s Kinetic and Jasper IoT platforms reside in the cloud, ADP focuses on the edge within the enterprise. The ability to manage the “internal edge” and integrate with the Kinetic platform is significant. Throw in the DevNet developer community, a large existing base of Aironet APs, and suddenly Cisco customers are doing IoT.To read this article in full or to leave a comment, please click here

FRRouting Software with EIGRP Support

In September 2016 I wrote the article about EIGRP support in Quagga network routing suite. More than one year later, I am going to check the progress of development EIGRP in Linux again. To do so, I have installed a fork of Quagga -  FRRouting (FRR) with EIGRP support on Linux Core. EIGRP routing daemon included inside FRR benefits from active development brought by Cumulus employees. For the purpose of FRR testing, I have created a minimalistic Linux Core Pure64 virtual machine  with FRR suite compiled as frr extension. Meanwhile, I have submitted FRR extension so it will be available in the next few days in Tinycore repository.

IDG Contributor Network: Validating cloud applications before going live

As businesses turn to the cloud as a primary resource in driving competitive advantage, migrating to this new environment should be undertaken in a deliberate and systematic manner. Although the promise of higher reliability coupled with a lower cost may lure businesses to the cloud, 41% of businesses find themselves poorly prepared for the migration and end up moving applications back to colocation facilities. For enterprises seeking to ensure success in their migration, and even those considering making the switch, the validation of cloud applications should be of primary concern.Developing cloud applications or migrating to a cloud environment means adding a lot of variable conditions between client and server. Applications that perform adequately on a corporate headquarters’ local network are often sluggish, slow, or downright unresponsive once deployed. WAN conditions, such as bandwidth constraints, latency, jitter and packet loss, can bring an application to a screeching halt once deployed within a cloud environment where distance is taken into consideration. In fact, 47% of businesses returning to traditional colocation cite latency as the biggest contributing factor to their leaving the cloud.To read this article in full or to leave a comment, please click here

Abstract, Automate & Secure — From Data Center to Cloud to Edge

By Milin Desai, Vice President of Products, NSBU

It feels like only yesterday when we started our journey into networking at VMware. Even from the early beginnings in 2011, it became clear to some of us that the abstraction and operations model of virtualization for compute and memory, which completely transformed the modern data center, was something we needed to extend to networking. We understood that that a network based on software and abstraction in the long run would extend beyond our customers’ data centers to public clouds and ultimately to the Edge.

We’ve been executing on this vision for almost eight years; reinventing data center networking and enabling our customers to be smarter about how they secure, manage and connect their applications and users.

Starting with the Data Center

The Nicira acquisition, alongside our internal innovations, resulted in the release of VMware NSX in 2013. VMware NSX made network virtualization a mainstream possibility for the data center. The goal was simple — abstract the application from the physical network and deliver the networking attributes in software at machine speeds. After four years, multiple thousands of customers and the creation of a billion-dollar run rate business, we have transformed the Continue reading
