Ladies and Gentlemen… Cloudflare TV!

I'm excited to announce the upcoming launch of Cloudflare TV. A 24x7 live television broadcast, streamed globally via the Cloudflare network. You can tune in to the pre-broadcast station and check out the upcoming schedule at: cloudflare.tv

I'm kicking off the first live broadcast starting at 12:00pm Pacific (1900 UTC) on Monday, June 8 with a conversation with Chris Young (add to calendar). Chris was most recently the CEO of McAfee and has had a career defining the cyber security industry, from his own startup Cyveillance in the 1990s, to leadership positions at AOL, RSA, VMWare, Cisco, and Intel. I hope you'll tune in and then stay tuned for all the content our team has in store.

Which leaves the question: why on earth is Cloudflare launching a 24x7 television station?

The Uniting Power of Television and Tech Conferences

I was born in the 70's, am a child of the 80's, and got started in my career in the 90's. In the background, throughout much of it, was linear television we watched together. Over the last few months I've learned that Michelle Zatlyn, my co-founder and Cloudflare's COO, and I shared a love of Children's Television Network's Continue reading

Worth Reading: Emerging Communications Technologies

Every few years someone within the ITU-T (the standard organization that mattered when we were still dealing with phones, virtual circuits and modems) realizes how obsolete they are and tries to hijack and/or fork the Internet protocol development. Their latest attempt is the “New IP” framework, and Geoff Huston did a great job completely tearing that stupidity apart in his May 2020 ISP column. My favorite quote:

It’s really not up to some crusty international committee to dictate future consumer preferences. Time and time again these committees with their lofty titles, such as “the Focus Group on Technologies for Network 2030” have been distinguished by their innate ability to see their considered prognostications comprehensively contradicted by reality! Their forebears in similar committees missed computer mainframes, then they failed to see the personal computer revolution, and were then totally surprised by the smartphone.

Enjoy!

On this 8th World IPv6 Launchiversary, Help Us Get More Websites Available Over IPv6

Eight years ago, on June 6, 2012, thousands of companies and organizations came together as part of World IPv6 Launch to permanently enable IPv6 for their websites and networks.

Today, we can see the success! If you visit the World IPv6 Launch measurements site, you can see some amazing numbers:

• Reliance Jio’s network in India has over 90% IPv6 deployment!
• Comcast’s huge network in the US is at 73% IPv6.
• The combined US wireless carriers are over 85% IPv6.
• Deutsche Telekom is over 68% IPv6.
• Claro in Brazil is at 62% IPv6.

Another major source of info, Google’s IPv6 statistics, show that over 30% of all traffic to Googles sites globally is now over IPv6. If you look at Google’s per-country IPv6 adoption, some countries are seeing up around 50% of all traffic to Google’s properties going over IPv6.

This is all fantastic to see. But of course, we want more IPv6 deployment!

Specifically, we want more web sites and services available over IPv6. Increasing numbers of IPv6-only mobile networks are being deployed around the world. To ensure that people can reach websites that are still only available over IPv4, many IPv6-only networks use IPv6-to-IPv4 gateways. But we Continue reading

On 27 February 2020, MalwareMustDie (MMD), a workgroup focused on the research and study of Linux malware, analysed and shared a new type of malware they called RHOMBUS.

Security researchers witnessed the deployment of PonyFinal ransomware at the end of extended human-operated attack campaigns. In a series of tweets, Microsoft Security Intelligence revealed it had observed human-operated campaigns laying in wait for the right moment to deploy PonyFinal ransomware as their final payload. —David Bisson

NetWalker (also known as Mailto) is the name given to a sophisticated family of Windows ransomware that has targeted corporate computer networks, encrypting the files it finds, and demanding that a cryptocurrency payment is made for the safe recovery of the encrypted data. —Graham Cluley

Memory isolation is a cornerstone security feature in the construction of every modern computer system. Allowing the simultaneous execution of multiple mutually distrusting applications at the same time on the same hardware, it is the basis of enabling secure execution of multiple processes on the same machine or in the cloud. The operating system is in charge of enforcing this isolation, as well Continue reading

Attention Resource Deficit

How much did your last laptop cost? You probably know down to the penny. How much time did it take for you to put together your last Powerpoint deck or fix an issue for a customer? You can probably track that time in the hours you recorded on your timesheet. What about the last big meeting you had of the department? Can you figure out how many hours combined of time that it took to get the business discussed? Pretty easy to calculate when you know how many people and how long it took.

All of these examples are ways that we track resources in the workplace. We want to know how many dollars were invested in a particular tool. We want to figure out how many hours someone has worked on a project or a proposal. We want to know how much of the company’s resources are being invested so we can track it and understand productivity and such. But when’s the last time you tracked your personal resources? I’m not talking about work you do or money you spend. I’m talking about something more personal than that. Because one of the things that I’ve seen recently that is Continue reading

DockerCon 2020: And … That’s a Wrap

DockerCon LIVE 2020 is a wrap, and you rocked it! Our first-ever virtual swing at the traditionally in-person event was a winner on so many levels.

One of our goals was to extend our reach to all developers and members of the community by making the conference digital and free of charge. Mission accomplished! A grand total of 78,000 folks signed up for the May 28 one-day online event.

You hailed from 193 countries (by some counts there are only 196 countries on the planet!). That includes far-flung places like Madagascar, Zimbabwe and even the Maldives. Heck, you even joined us from the Vatican City State (pop. about 800).

Whether you were a seasoned developer or just starting out, our content game was strong. Best practices, how-tos, new product features and use cases, technical deep dives, open source projects—you name it, it was on the menu.

One of our key challenges was replicating the interactivity and spontaneity of in-person events in a virtual setting, but our efforts paid off. We made sure speakers and interviewees were available for live Q&A for their whole session to engage with attendees, resulting in over 21K chats. And remember those popular Hallway Tracks Continue reading

How we use HashiCorp Nomad

In this blog post, we will walk you through the reliability model of services running in our more than 200 edge cities worldwide. Then, we will go over how deploying a new dynamic task scheduling system, HashiCorp Nomad, helped us improve the availability of services in each of those data centers, covering how we deployed Nomad and the challenges we overcame along the way. Finally, we will show you both how we currently use Nomad and how we are planning on using it in the future.

Reliability model of services running in each data center

For this blog post, we will distinguish between two different categories of services running in each data center:

• Customer-facing services: all of our stack of products that our customers use, such as caching, WAF, DDoS protection, rate-limiting, load-balancing, etc.
• Management services: software required to operate the data center, that is not in the direct request path of customer traffic.

Customer-facing services

The reliability model of our customer-facing services is to run them on all machines in each data center. This works well as it allows each data center’s capacity to scale dynamically by adding more machines.

Scaling is especially made easy thanks to Continue reading

Video: Public Cloud Networking Overview

Donal O Duibhir was trying to get me to present at INOG for ages, and as much as I’d love to get to Ireland we always had a scheduling conflict.

Last week we finally made it work - unfortunately only in a virtual event, so I got none of the famous Irish beer - and the video about alternate universes of public cloud networking is already online.

DevAsc – Introduction to JSON

Introduction

JSON, JavaScript Object Notation, is one of the usual suspects when it comes to network automation. YAML and XML being the other two. It’s easy for machines to parse and generate and the readability is good, better than XML, although YAML is easier for humans to read.

JSON is based on a subset of the JavaScript programming language, as the name implies.

JSON, just like YAML, supports single values, lists, and key/value pairs.

JSON is commonly used to interchange between different formats.

Syntax

JSON has no requirement for indentation or white space, which YAML has. That said, to make it human readable, it still makes sense to use white space and spaces, most likely either two or four.

• Strings MUST use double quotes
• Object literal names MUST be lowercase (null, false, true etc)
• Special characters need to be escaped
• { says “begin object”
• } says “end object”
• [ says “begin array”
• ] says “end array”
• : separates key and value in key/value pair
• , separates key/value pair in an object or separates values in an array, think of it as “expect another one”

Data Types

JSON supports the following data types:

• Object
• String
• Number
• Boolean
• Null
• Array

We’ll Continue reading
