It’s All About Business…

A few years ago I got cornered by an enthusiastic academic praising the beauties of his cryptography-based system that would (after replacing the whole Internet) solve all the supposed woes we’re facing with BGP today.

His ideas were technically sound, but probably won’t ever see widespread adoption – it doesn’t matter if you have great ideas if there’s not enough motivation to implementing them (The Myths of Innovation is a mandatory reading if you’re interested in these topics).

Accelerated Data Plane Performance Using Enhanced Data Path in NUMA Architecture

Authors: Jambi Ganbar (Sr. Technical Solutions Manager, NFV), Jubin Thomas (NSX Information Experience team)

Overview

Some workloads demand accelerated and predictable networking performance.  Our Network Functions Virtualization (NFV) customers and some of our financial, media, and high-performance computing (HPC) customers deploy these workloads. These workloads process a lot of network traffic. Network traffic in the virtual domain relies heavily on CPU cycles and the number of CPU cores available on the host.  These CPU resources are used by the workload to perform its task and by the hypervisor layer to deliver network traffic to and from the application.

In this blog, we discuss the configuration required to achieve accelerated data plane performance in modern multiple NUMA architecture hosts. This blog accompanies a new white paper we just released on the subject.  The white paper can be found here.

With the introduction of NSX-T version 2.2, we added a new mode of operations in the NSX-controlled virtual distributed switch. We refer to this switch as N-VDS.  This new mode is called Enhanced Data Path and is often indicated as N-VDS (E).  N-VDS (E) is one of the core building blocks in achieving accelerated data plane Continue reading

Lagos, Nigeria – Cloudflare’s 155th city

Lagos, Nigeria - Cloudflare’s 155th city

At just shy of 200 million, Nigeria is the most populous country in Africa (Ethiopia is second and Egypt is third). That’s a lot of people to communicate with the world - and communicate they all do!

Lagos, Nigeria - Cloudflare’s 155th city

According to a published report earlier this year, 84% of the Nigerian population own a mobile device (193 million population and 162 million mobile subscriptions). Again, that’s #1 for any country in Africa. But why so connected? Maybe because Nigeria (and Lagos specifically) is always on the move!

Lagos, as those that know the city say, never sleeps, it’s filled with color from the food to fashion to even the diverse people going about their business. The vibrancy of the city is like a hard slap to the face, no matter what you have been told, your first time here will still knock you out. In Lagos, anything is possible, from the sadness of poverty to the clearly visible upper class, the city sucks you in like a surfers dream wave. Visitor come into Lagos and leave feeling like they’ve been through a unique experience. The traffic is mind blowing and the same goes for the work pace.

Lagos, a city always on Continue reading

AWS ABCs — Network Building Blocks

Given that my technical background is largely in the networking space (exhibit A, exhibit B, exhibit C (CIE)), one of the first things I tried to wrap my head around when being introduced to AWS is how networking works in the AWS cloud.

What I attempted to do was build a mental model by relating cloud networking constructs such as Virtual Private Cloud (VPC), subnets, and routing tables to on-prem, physical networking constructs. This worked pretty well but I did get tripped up at times because some of these constructs don't map exactly one-for-one.

This post will explain the mental model I used while also calling attention to the elements or behaviors that don't map exactly between on-prem and AWS.

IBM-Red Hat deal: What the companies say

IBM announced yesterday that it is buying Red Hat for $34 billion, making it IBM's largest deal to date and the third largest in the history in the US tech industry.After announcing the plan to close the deal sometime in the second half of next year, executives from the two companies held a joint conference call fleshing out the details. Here's what they had to say.According to Arvind Krishna, Senior Vice President of Hybrid Cloud at IBM, this move represents a "game changer" that will redefine the cloud market. Krishna was joined by Paul Cormier, Executive Vice President and President of Products and Technologies at Red Hat.To read this article in full, please click here

Inaugural 2018 Gartner Magic Quadrant for WAN Edge Infrastructure and VMware NSX SD-WAN by VeloCloud

Congratulations to the VMware NSX SD-WAN by VeloCloud team for its recognition as a Leader in the first Gartner Magic Quadrant for WAN Edge Infrastructure! The report is the first Magic Quadrant that includes evaluation of SD-WAN vendors and to be named a leader with the position furthest on Completeness of Vision is quite an honor.

VeloCloud, now part of VMware, began with the idea to remedy branch networking issues because the networks of yesterday were optimized to haul traffic back to the datacenter, not to the cloud where applications of today are housed. SD-WAN has solved for this issue amongst a plethora of others, becoming a technology disruptor in a way that nothing else has been in decades.

SD-WAN has, in a very short period of time, transitioned from a networking “nice-to-have” to a necessary component of the network infrastructure.  We’re excited to have Gartner recognize another key component of our rapidly growing networking portfolio and integral product in the VMware Virtual Cloud Network vision to provide the connectivity across cloud, data center, branches, end user, and applications regardless of where they will be used.

Understanding mass data fragmentation

The digital transformation era is upon us, and it’s changing the business landscape faster than ever.I’ve seen numerous studies that show that digital companies are more profitable and have more share in their respective markets. Businesses that master being digital will be able to sustain market leadership, and those that can’t will struggle to survive; many will go away.This is why digital transformation is now a top initiative for every business and IT leader. A recent ZK Research study found that a whopping 89% of organizations now have at least one digital initiative under way, showing the level of interest across all industry verticals.To read this article in full, please click here

Understanding mass data fragmentation

The digital transformation era is upon us, and it’s changing the business landscape faster than ever. I’ve seen numerous studies that show that digital companies are more profitable and have more share in their respective markets.

A recent ZK Research study found that a whopping 89% of organizations now have at least one digital initiative under way, showing the level of interest across all industry verticals.Digital success lies in the quality of data The path to becoming a digital company requires more than a CIO snapping his fingers and declaring their organization digital. Success lies in being able to find the key insights from the massive amounts of data that businesses have today. This requires machine learning–driven analytics, and there has been a significant amount of media focus on that topic. The other half of the equation is data. Machine learning alone doesn’t do anything. It needs to analyze data, and as the old axiom goes, good data leads Continue reading

Ossification and Fragmentation: The Once and Future ‘net

Mostafa Ammar, out of Georgia Tech (not my alma mater, but many of my engineering family are alumni there), recently posted an interesting paper titled The Service-Infrastructure Cycle, Ossification, and the Fragmentation of the Internet. I have argued elsewhere that we are seeing the fragmentation of the global Internet into multiple smaller pieces, primarily based on the centralization of content hosting combined with the rational economic decisions of the large-scale hosting services. The paper in hand takes a slightly different path to reach the same conclusion.

TL;DR
  • Networks are built based on a cycle of infrastructure modifications to support services
  • When new services are added, pressure builds to redesign the network to support these new services
  • Networks can ossify over time so they cannot be easily modified to support new services
  • This causes pressure, and eventually a more radical change, such as the fracturing of the network

 
The author begins by noting networks are designed to provide a set of services. Each design paradigm not only supports the services it was designed for, but also allows for some headroom, which allows users to deploy new, unanticipated services. Over time, as newer services are deployed, the requirements on the network Continue reading

Plenipot 2018 – What’s Up for the Internet?

Two weeks ago, the Editorial Board of the New York Times published a piece predicting that the Internet is heading for a breakup.

Based on the comments made by Alphabet Chairman Eric Schmidt during a private event the Times set out to paint a picture of a world with three Internets.

The timing is understandable. We’re in a world where things like the European Union’s General Data Protection Regulation is met with an equal measure of acceptance, annoyance, and confusion around the world.

And, just last week, my colleague Konstantinos Komaitis warned about what could happen as decision-makers are imposing rules that spill over onto the Internet, hamper innovation, deter investment in their own countries, and risk creating new digital divides.

These events set the stage for the Plenipotentiary meeting of the International Telecommunications Union (ITU).

And, in today’s climate, there are many who believe the Internet could be failing us.

So, we need to speak loudly about the fact that the Internet is not failing.

So far, I think the Internet has been a force for good.

The Internet allows us to do things like expand our access to education, build businesses, and grow our economy.

The Internet Continue reading
