Helping To Build Cloudflare, Part 4: Public Engagement
This is part 4 of a six part series based on a talk I gave in Trento, Italy. To start from the beginning go here.
We don’t believe that any of our software, not a single line of code, provides us with a long-term advantage. We could, today, open source every single line of code at Cloudflare and we don’t believe we’d be hurt by it.
How we think about Open Source
Why don’t we? We actually do open source a lot of code, but we try to be thoughtful about it. Firstly, a lot of our code is so Cloudflare-specific, full of logic about how our service works, that it’s not generic enough for someone else to pick up and use for their service. So, for example, open sourcing the code that runs our web front end would be largely useless.
But other bits of software are generic. There’s currently a debate going on internally about a piece of software called Quicksilver. I mentioned before that Cloudflare used a distributed key-value store to send configuration to machines across the world. We used to use an open source project called Kyoto Tycoon. It was pretty cool.

Tech Field Day Extra @ CLEUR19 Recap
I spent most of last week with a great team of fellow networking and security engineers in a windowless room listening to good, bad and plain boring presentations from (mostly) Cisco presenters describing new technologies and solutions – the yearly Tech Field Day Extra @ Cisco Live Europe event.
This year’s hit rate (the percentage of good presentations) was about 50% and these are the ones I found worth watching (in chronological order):

Emulating Juniper Devices – Various options
Hi,
I have got a lot of requests for writing up a blog post on various Methods of emulating Juniper devices for practice.
Note : For 2/3 methods to work, you need to have official Junos software (vmx-vcp and vmx-vfp)
Method 1 – Gns3
Most popular and Familiar Method – Install via gns3
After installing Gns3, download the
Vmx-vfp Appliance – https://docs.gns3.com/appliances/juniper-vmx-vfp.html
Vmx-vcp Appliance – https://docs.gns3.com/appliances/juniper-vmx-vcp.html
Documentation is straight forward, all you need to do is double click on the appliance and upload the image when requested, as easy as it can get.
Method2 – Vagrant
Use Juniper uploaded Images via vagrant.
Most of Juniper Vqfx / JNCIE-DC practice came up from a vagrant, You don’t need to have any official images or access to Juniper software downloads. The downside is that it only supports VQFX and generic SRX, but for most of the Routing protocol and MPLS learning this should be good.
https://app.vagrantup.com/boxes/search?utf8=%E2%9C%93&sort=downloads&provider=&q=juniper
https://app.vagrantup.com/juniper/boxes/vqfx10k-re
https://app.vagrantup.com/juniper/boxes/vqfx10k-pfe
Again, following Github link, will auto setup the topology without you worrying about much details to vagrant.
https://github.com/Juniper/vqfx10k-vagrant -> Go into a specific folder and say vagrant up, that should take Continue reading
Helping To Build Cloudflare, Part 2: The Most Difficult Two Weeks
This is part 2 of a six part series based on a talk I gave in Trento, Italy. Part 1 is here.
It’s always best to speak plainly and honestly about the situation you are in. Or as Matthew Prince likes to put it “Panic Early”. Long ago I started a company in Silicon Valley which had the most beautiful code. We could have taught a computer science course from the code base. But we had hardly any customers and we failed to “Panic Early” and not face up to the fact that our market was too small.
Ironically, the CEO of that company used to tell people “Get bad news out fast”. This is a good maxim to live by, if you have bad news then deliver it quickly and clearly. If you don’t the bad news won’t go away, and the situation will likely get worse.
Cloudbleed
Cloudflare had a very, very serious security problem back in 2017. This problem became known as Cloudbleed. We had, without knowing it, been leaking memory from inside our machines into responses returned to web browsers. And because our machines are shared across millions of web sites, that meant that HTTP requests Continue reading
Build a network emulator using Libvirt
I want to explore some of the network virtualization and emulation building blocks available on a Linux system. In this post, I create a simple network emulation scenario using Libvirt, the Qemu/KVM hypervisor, and Linux bridges to create and manage interconnected virtual machines on a host system.
Libvirt provides a command-line interface that hides the low-level virtualization and networking details, enabling one to easily create and manage virtual networking scenarios. It is already used as a basis for some existing network emulators, and other applications and tools. It is available in almost every Linux distribution.
The network emulation scenario
As you work through the examples in this post, you will create a very simple network topology which is intended to demonstrate the use of Libvirt and other virtualization tools to build a network emulator and is not intended to emulate a real-world network. However, once you understand its operation, you may use Libvirt to create large, complex network topologies intended to emulate real-world network scenarios.
The example I created for this post consists of three virtual machines serving as routers connected to each other in a ring topology. On each side of this emulated network, you will create Continue reading

Ericsson Touts 4 Cellular IoT Segments to Serve Industry Verticals
One analyst said Ericsson is responding to a concern by carriers about following the old fashioned "build it and they will come" approach to network deployment.
Weekend Reads 020119
But when designing underlying cyber protections, too many architects are taking zero trust to be the primary objective. This is a misinterpretation. In the first instance, we should look to protect our resources from attack. What zero trust reminds us is that we are fallible, and that we should put in place backup plans in the form of monitoring and incident response for the (hopefully rare) cases where our protection Continue reading
Advanced Solutions Customer Story Part 1: Why NSX-T?
Customer Overview
Advanced Solutions, a DXC Technology company, was formed in 2004 and employs about 500 staff to support the government of the Canadian province of British Columbia and other public sector customers with IT and business process solutions. For government agencies and services to continue operating efficiently and effectively, it is essential that the IT resources that they require are provided quickly and accurately.
Key Pain Points
All IT organizations are acutely familiar with the wide range of pain points and obstacles that can stand in the way of delivering resources to empower their businesses to move with speed and agility. One of the most common hindrances to IT, and therefore business agility is painfully slow provisioning processes, which can take weeks just to provision an application. The most common bottleneck within these processes is provisioning networking and security services. This is a key pain point for Advanced Solutions, but one that VMware is helping them solve with the VMware NSX Data Center network virtualization platform.
Dan Deane, Solutions Lead at Advanced Solutions says, “The key IT pain points that VMware solutions are helping us solve are around networking and provisioning.”
New Use Cases
Advanced Solutions was Continue reading
