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.

Maximilian Wilhelm had great fun turning my usual black-and-white statements into tweets, here’s a selection of them:

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

Startup lands $100 million to build floating data centers

Data centers and water seem to go together, despite the fact water is bad for electronics. Many hyperscale data centers are built near rivers for use as hydroelectric power sources, liquid cooling is growing in popularity, and in one extreme case, Microsoft sunk a mini data center off the coast of northern England.The next step, it seems, is the floating data center, one on the water and easily accessible but also mobile. A startup called Nautilus Data Technologies has lined up $100 million in funding to build a six-megawatt floating colocation facility that it says will be cheaper and more efficient than traditional facilities.To read this article in full, please click here

Making Intermediaries Liable for Encrypted Content Breaks Trust and Security

In December 2018, the Indian Ministry of Electronics & Information Technology (MeitY) proposed a significant change to its intermediary rules. The draft Information Technology  [Intermediaries Guidelines (Amendment) Rules] 2018 seeks to tie tech platforms’ (e.g., social media) protections from liability to an obligation to monitor and filter their users’ content. One of the proposed obligations is to ensure the traceability of messages, even if a service is end-to-end encrypted.

India is just one of many countries around the world experimenting with the idea that Internet intermediaries – specifically social media companies, like Facebook and Twitter – should no longer have immunity from liability for the content shared by their users. Other examples include the U.S. Eliminating Abusive and Rampant Neglect of Interactive Technologies Act of 2020 (the EARN IT Act), and the recent U.S. Executive Order on Preventing Online Censorship.

The motivation for changing the status quo varies, from wanting traceability of messages to counter the spread of disinformation or CSEM, to stopping objectionable content from being spread on social media, to preventing political messages from being labeled (e.g., as “misleading information”). Similarly, the approaches being considered to achieve this vary, ranging from Continue reading

Multi-arch build, what about CircleCI?

Following the previous article where we saw how to build multi arch images using GitHub Actions, we will now show how to do the same thing using another CI. In this article, we’ll consider CircleCI, which is one of the most used CI SaaS.

To start building your image with CircleCI, you will first need to create .circleci/config.yml file:

version: 2
jobs:
  build:
    docker:
      - image: docker:stable
    steps:
      - checkout
      - setup_remote_docker:
          version: 18.09.3
      - run: docker version

You may notice that we specified using version 18.09.3 of the Docker Engine because buildx requires version 18.09 or later but CircleCI doesn’t provide any version above 18.09.3.

At this point we are able to interact with the Docker CLI but we don’t yet have the buildx plugin installed. To install it, we will download a build from GitHub.

version: 2
jobs:
  build:
    docker:
      - image: docker:stable
    steps:
      - checkout
      - setup_remote_docker:
          version: 18.09.3

Interesting: Measuring End-to-End Latency in Web Browser

CloudFlare launched yet another service: transfer speed- and latency measurements done from a web browser. While it’s pretty obvious how you could measure transfer speed (start an asynchronous transfer, register for the JavaScript onreadystatechange event to notice out when it has completed, and compute the transfer rate), measuring latency seems like a bit of black magic. After all, you can’t do a ping from a web browser, can you?

VMware Announces Intent to Acquire Lastline

By Tom Gillis, SVP and GM, Networking and Security Business Unit, VMware

EDITORIAL UPDATE: On June 18, 2020 VMware officially closed its acquisition of Lastline. The blog post below has been amended to reflect that announcement.

VMware announced its intent to acquire Lastline, a pioneer in anti-malware research and AI-powered network detection and response, and on June 18, 2020 the acquisition closed. This is an important step forward for VMware’s vision of Intrinsic Security, as it allows us to further take advantage of the intrinsic attributes of our virtualization platform to yield innovative security capabilities. Our aim is not to replicate that which exists today, but rather to build security solutions that we can uniquely deliver, spanning from the heart of the data center to users in a branch office and all the way to mobile users at home or on the road.

In the security industry, the nature of threats changes so rapidly that security technology is constantly being re-invented. In this context, it is not the algorithms per se that matter; it is the people that make the algorithms. Great people build great products, and great products build great companies. And that’s why we are so Continue reading
