Which cloud should you use? It may depend on what you need to do with it. What Zach Bjornson needs to do is process large amounts scientific data as fast as possible, which means reading data into memory as fast as possible. So, he made benchmark using Google's new multi-cloud PerfKitBenchmarker, to figure out which cloud was best for the job.
The results are in a very detailed article: AWS S3 vs Google Cloud vs Azure: Cloud Storage Performance. Feel free to datamine the results for more insights, but overall his conclusions are:
It’s an exciting time in networking!
Google and Amazon recently gave the IT community a glimpse behind the curtain of web-IT, revealing the outcome of their pioneering efforts. It’s no surprise that they’ve settled on IP fabrics and network virtualization to provide both scale and isolation. Web giants Facebook and Microsoft are both driving open hardware in an effort to eliminate the lock that industry incumbents have on networking solutions.
You know that you’re onto something when industry analysts start counting things – Gartner’s Andrew Lerner recently published his perspective on the networking industry; by 2017, they expect 50% of global enterprises to embrace web-IT architectures.
Last year, we saw the uptake of modern networking paradigms. Practitioners of NetDevOps are driving automation practices into the network domain. IP storage solutions are rampant, benefiting from high capacity IP fabrics. Brite-box hardware suppliers have enabled web-IT with procurement, logistics, and support capability that meets the needs of any organization. Network virtualization solutions from VMware NSX and up-and-comer Nuage are getting the nod in enterprises. The OpenStack community applied a laser-like focus on Neutron which in turn has promoted virtual network solutions from Akanda and Midokura to be deployed at scale. We’re seeing Continue reading

Back to GIT! Just to have a quick recap of the things we’ve seen in the first part of our GIT deep dive, I am going to create a brand new repo, some files and commit everything:
$ mkdir myrepo2
$ cd myrepo2
$ git init
Initialized empty Git repository in /Users/huidesa/myrepo2/.git/
$ touch file1
$ touch license_agreement
$ touch installer.exe
$ touch hello.lib
$ git status
On branch master
Initial commit
Untracked files:
(use “git add <file>…” to include in what will be committed)
file1
hello.lib
installer.exe
license_agreement
nothing added to commit but untracked files present (use “git add” to track)
$ git add *
$ git status
On branch master
Initial commit
Changes to be committed:
(use “git rm –cached <file>…” to unstage)
new file: file1
new file: hello.lib

Is IP Telephony dead? “When a technology market stops growing, it’s dead” — this is the call and mantra of the technology world. Since we live in a percentage driven world, the first question we seem to ask is, “what story do the percentages tell?” Tom raises the counterpoint — it doesn’t matter if the market is growing or not, there’s still a huge need for phones on desks. Who is right?
But I think this entire percentage driven thing points to a problem in our technology culture. Let me tell you a story…
We have a dog. A black and white (black with white spots as my daughter tells me, because his nose is black) English Cocker Spaniel. With black spots in his white spots. Spaniels, if you’re not familiar with them, are balls of energy. They never really “grow up” — not really, anyway. The most sedate Spaniel breed in the world is a Clumber, and they’re not what you’d call “down” personalities. Now, when we first brought this little bundle of energy home, we weighed him on a regular basis. At some point, he slowed down in gaining weight, and eventually he stopped gaining weight altogether.

Internet Exchange Points (IXPs) or Network Access Points (NAPs) facilities are where networks meet, participating in what's known as peering, which interconnects various parts of the global Internet.
At CloudFlare we are dedicated to peering. So much so that we just joined our 100th Internet Exchange point!

According to Wikipedia:
“In computer networking, peering is a voluntary interconnection of administratively separate Internet networks for the purpose of exchanging traffic between the users of each network”
In reality this normally means a physical place where two different networks (they could be backbones, CDNs, mobile networks or broadband ISPs) connect their respective networks together to exchange traffic. Over the last fifteen years, there has been a major expansion in network interconnections, running parallel to the enormous expansion of the global Internet. This expansion includes new data centre facilities being developed to house network equipment. Some of those data centres have attracted massive numbers of networks, in no small part due to the thriving Internet Exchanges Points (both new and existing) that operate within them. London with the LINX and LONAP exchanges, Amsterdam with AMS-IX and NL-IX exchanges, Frankfurt with DE-CIX and ECIX exchanges Continue reading
The new 802.11ah wireless standard is compelling for IoT, but don't get too excited just yet.
Flash-based storage and the cloud will play big roles in meeting enterprise storage needs.
In theory, you should shut down a network device with a well-defined procedure:
In practice, network devices don’t have a shutdown command, and reload typically just restarts the network OS.

This isn’t a new idea, and certainly not anything that I came up with or created. I’m simply presenting it here as an alternative option to the approach of using YAML with Vagrant for multi-machine environments (some people may prefer JSON over YAML).
If you’re unfamiliar with Vagrant, I’d start with my introduction to Vagrant. Then I’d recommend reviewing my original article on using YAML with Vagrant, followed by the updated/improved method that addresses a shortcoming with the original approach. These earlier posts will provide some basics that I’ll build on in this post.
To use a JSON-formatted data file as an external data source for Vagrant, the code in the Vagrantfile looks really similar to the code you’d use for YAML:
# -*- mode: ruby -*-
# # vi: set ft=ruby :
# Specify minimum Vagrant version and Vagrant API version
Vagrant.require_version '>= 1.6.0'
VAGRANTFILE_API_VERSION = '2'
# Require JSON module
require 'json'
# Read YAML file with box details
servers = JSON.parse(File.read(File.join(File.dirname Continue readingI’ve noticed recently a lot of annoying ads following me around on the Internet. Not just showing up every so often in the browser side panel, but some embedded deep within the pages I’m viewing, making them very difficult to ignore. Often the ads are for something I’ve already bought or something I’ve decided not […]
