CLKscrew: Another side channel you didn’t know about

Network engineers focus on protocols and software, but somehow all of this work must connect to the hardware on which packets are switched, and data is processed. A big part of the physical side of what networks “do” is power—how it is used, and how it is managed. The availability of power is one of the points driving centralization; power is not universally available at a single price. If cloud is cheaper, it’s probably not because of the infrastructure, but rather because of the power and real estate costs.

A second factor in processing is the amount of heat produced in processing. Data center designers expend a lot of energy in dealing with heat problems. Heat production is directly related to power usage; each increase in power consumption for processing shows up as heat somewhere—heat which must be removed from the equipment and the environment.

It is important, therefore, to optimize power usage. To do this, many processors today have power management interfaces allowing software to control the speed at which a processor runs. For instance, Kevin Myers (who blogs here) posted a recent experiment with pings running while a laptop is plugged in and on battery—

Building a Diverse Business Development Team in EMEA

Cloudflare’s mission is to help build a better Internet, and we are also serious about building a diverse workforce where everyone can be themselves, regardless of their gender, sexual orientation, or cultural background.

The Recruiting team sat down with Anil Karavadra, EMEA Head of Business Development, to find out how he has built a diverse team since he joined.

Recruiting Team: First question Anil, how did you end up at Cloudflare?
Anil Karavadra: Funny story about this--I was actually approached by my boss! He reached out to me and said “Hey would you be interested in joining Cloudflare?”, and initially I said no because I hadn’t heard of Cloudflare before! Then he suggested “Well how about we share some best practices?”, and I said okay, although I knew he was going to try and pitch Cloudflare to me. After I had a chat with him and he shared his vision to grow the EMEA BDR organisation. This sounded interesting to me so I then went through the interview process and got through. Now that I’m here I love it.

BrandPost: Is It Time to Replace Your Network’s Annual Check-Up?

Ciena Daniele Loffreda, Senior Advisor, Industry Marketing The evolution toward a more holistic, personalized health maintenance program will create an explosion of data putting more pressure on our communication networks. Is your network healthy enough to make the sharing of this information possible? Ciena’s Daniele Loffreda discusses.In the past, an annual visit to our primary care doctor was considered common practice. But in today's era of personalized, precision medicine, the annual checkup may not be as necessary for otherwise healthy adults. In fact, research conducted by the Cochrane Collaboration suggests that yearly visits in the absence of symptoms are not beneficial. According to the National Center for Policy Analysis, patients in the United States visit their physicians for annual checkups more than 44 million times per year despite having no medical issues or concerns.To read this article in full, please click here

First APrIGF in the Pacific a Resounding Success

The 2018 Asia Pacific Regional Internet Governance Forum (APrIGF) which was held in Port Vila, Vanuatu from August 13-16 came to an exciting close after a week of valuable dialogue on Internet Governance issues in the region.  This was the first time the APrIGF was held in the Pacific and the local hosts, Vanuatu’s Office of the Government Chief Information Officer (OGCIO), Vanuatu Telecommunications and Radiocommunications Regulator (TRR), and the local people of Vanuatu showed the APrIGF community what Pacific Island hospitality is all about.

The community had the privilege of having APrIGF 2018 opened by none other than the Vanuatu Prime Minister, Charlot Salwai. Also present at APrIGF 2018 and delivering his keynote address was the godfather of the Internet himself, Vint Cerf who took time to contribute in various discussions and engage with participants. With the theme of Empowering Communities in Asia Pacific to Build an Affordable, Inclusive, Open and Secure Internet, the calibre of delegates speaks volumes for the importance of such a dialogue.

Participants from all over Asia-Pacific, representing various stakeholder groups, were present to contribute to discussion and engage in the proceedings. This was the culmination of months of planning and execution by the Continue reading

NASA to use data lasers to beam data from space to Earth

Starting in 2019, NASA will begin using laser communications technology to "enable greater return of science data from space." The reason is laser is more bandwidth-friendly than classic radio for data delivery, plus it's more secure, NASA says in a newly released explainer of its plans.Laser signals from space will be much harder to hack than old-school radio because the signal is more concentrated, the agency says on its website. Plus, the higher frequencies provide more bandwidth — important for space data crunching. And laser equipment is lighter, allowing for longer missions, among other benefits.To read this article in full, please click here

Introduction to Infrastructure as Code

Linux kernel 4.18: Better security, leaner code

The recent release of Linux kernel 4.18 followed closely by the releases of 4.18.1, 4.18.2, 4.18.3, 4.18.4, and 4.18.5 brings some important changes to the Linux landscape along with a boatload of tweaks, fixes, and improvements.While many of the more significant changes might knock the socks off developers who have been aiming at these advancements for quite some time, the bulk of them are likely to go unnoticed by the broad expanse of Linux users. Here we take a look at some of the things this new kernel brings to our systems that might just make your something-to-get-a-little-excited-about list.[ Also read: Invaluable tips and tricks for troubleshooting Linux ] Code Cleanup For one thing, the 4.18 kernel has brought about the surprising removal of nearly 100,000 lines of outdated code. That's a lot of code! Does this mean that any of your favorite features may have been ripped out? That is not very likely. This code cleanup does means that a lot of code deadwood has been carefully expunged from the kernel along with one significant chunk. As a result, the new kernel should take up less memory, Continue reading

Are Containers Replacing Virtual Machines?

With 20,000 partners and attendees converging at VMworld in Las Vegas this week, we often get asked if containers are replacing virtual machines (VMs). Many of our Docker Enterprise customers do run their containers on virtualized infrastructure while others run it on bare metal. Docker provides IT and operators choice on where to run their applications – in a virtual machine, on bare metal, or in the cloud. In this blog we’ll provide a few thoughts on the relationship between VMs and containers.

Containers versus Virtual Machines

Point #1: Containers Are More Agile than VMs

At this stage of container maturity, there is very little doubt that containers give both developers and operators more agility. Containers deploy quickly, deliver immutable infrastructure and solve the age-old “works on my machine” problem. They also replace the traditional patching process, allowing organizations to respond to issues faster and making applications easier to maintain.

Point #2: Containers Enable Hybrid and Multi-Cloud Adoption

Once containerized, applications can be deployed on any infrastructure – on virtual machines, on bare metal, and on various public clouds running different hypervisors. Many organizations start with running containers on their virtualized infrastructure and find it easier to then migrate to Continue reading

Traditional Leaf-and-Spine Fabric Versus Cisco ACI

One of my subscribers wondered whether it would make sense to build a traditional leaf-and-spine fabric or go for Cisco ACI. He started his email with:

One option is a "standalone" Spine/Leaf VXLAN-with EVPN deployment based on Nexus equipment. This approach could probably be accompanied by some kind of automation like Ansible to ease operation/maintenance of the network.

This is what I would do these days if the customer feels comfortable investing at least the minimum amount of work into an automation solution. Having simpler technology + well-understood automation solution is (in my biased opinion) better than having a complex black box.

STTR: A system for tracking all vehicles all the time at the edge of the network

STTR: A system for tracking all vehicles all the time at the edge of the network Xu et al., DEBS’18

With apologies for only bringing you two paper write-ups this week: we moved house, which turns out to be not at all conducive to quiet study of research papers!

Today’s smart camera surveillance systems are largely alert based, which gives two main modes of operation: either you know in advance the vehicles of interest so that you can detect them in real time, or you have to trawl through lots of camera footage post-facto (expensive and time-consuming). STTR is a system designed to track all of the vehicles all of the time, and store their trajectories for ever. I certainly have mixed feelings about the kinds of state surveillance and privacy invasions that enables (it’s trivial to link back to individuals given trajectories over time), but here we’ll just focus on the technology. Since the system is design with pluggable detection and matching algorithms, then given some calculations around volume it ought to be possible to use it to track objects other than vehicles. People for example?

Assuming the availability of suitable detection and matching (figuring out if Continue reading
