Top 5 tips for transitioning to 100G networking
No doubt about it: the prospect of adding another zero to the end of your top network speeds is exciting. And the reward of the immediately noticeable performance improvement never gets old. Speed makes a noticeable, and not just measurable, difference. And with the massive increase in the amount of data servers need to process, 100G is soon going to be a necessity for many organizations.
But increasing network speed is about more than pushing more bits across a wire. Faster networks enable you to squeeze more out of your physical rack space. You need fewer servers, fewer network connections, and – dare I say it – fewer switches. It’s true. A faster network lets you pack more computing into the same space.
Whether you plan to do a forklift upgrade to 100G or intend to replace one switch at a time, there are some key things you need to know to avoid getting locked into one switch vendor or losing backward compatibility with your existing equipment. In this post, I’m going to give you my top 5 tips for making transitioning to 100G networking a smooth one.
Tip No. 1: Decide where 25G/100G makes sense
First, a little background. Continue reading

Test New Features and Iterate Quickly with Cloudflare Workers

At Cloudflare, we believe that getting new products and features into the hands of customers as soon as possible is the best way to get great feedback. The thing about releasing products early and often is that sometimes they might not be initially ready for your entire user base. You might want to provide access to only particular sets of customers that may be: power users, those who have expressed interest participating in a beta, or customers in need of a new feature the most.
As I have been meeting with many of the users who were in our own Workers beta program, I’ve seen (somewhat unsurprisingly) that many of our users share the same belief that they should be getting feedback from their own users early and often.
However, I was surprised to learn about the difficulty that many beta program members had in creating the necessary controls to quickly and securely gate new or deprecated features when testing and releasing updates.
Below are some ideas and recipes I’ve seen implemented inside of Cloudflare Workers to ensure the appropriate customers have access to the correct features.
How Workers Work
First, a brief Continue reading

Article 13 of the Copyright Directive Raises Serious Questions
The next couple of days will be important for the future of the Internet, as the European Parliament’s Committee on Legal Affairs (JURI) will vote on the proposed Copyright Directive. The Directive, which aims to update and reinforce the rights of rights holders within Europe’s Digital Market, is largely a positive step forward inasmuch as the law needs to be updated in light of modern technologies and the Internet. However, Article 13 of the directive raises serious questions about the implications for free expression, creativity, and the freedom to publish.
Under this article, “information society service providers” will be required to use “content recognition technologies” to scan videos, audio, text, photos, and code to the detriment of open-source software communities, remixers, livestreamers, and meme creators.
Last week, many Internet luminaries penned an open letter to the President of the European Parliament asking for the deletion of Article 13. The Internet Society agrees with the concerns raised in this letter and urges the Parliament to reconsider Article 13 in light of the implications for the open Internet.
In the meantime, civil society and academia, including EFF, EDRI, Creative Commons, and the Max Planck Institute for Innovation and Competition Continue reading

Research: Lessons from Evolve or Die
Google runs what is probably one of the largest networks in the world. Because of this, network engineers often have two sorts of reactions to anything Google publishes, or does. The first is “my network is not that big, nor that complicated, so I don’t really care what Google is doing.” This is the “you are not a hyperscaler” (YANAH) reaction. The second, and probably more common, reaction is: whatever Google is doing must be good, so I should do the same thing. A healthier reaction to both of these is to examine these papers, and the work done by other hyperscalers, to find the common techniques they are applying to large scale networks, and then see where they might be turned into, or support, common network design principles. This is the task before us today in looking at a paper published in 2016 by Google called Evolve or Die: High Availablility Design Principles Drawn from Google’s Network Infrastructure.
The first part of this paper discusses the basic Google architecture, including a rough layout of the kinds of modules they deploy, the module generations, and the interconnectivity between those modules. This is useful background information for understanding the remainder Continue reading
