Announcing our Spring Developer Speaker Series

We love developers.

Late last year, we hosted Full Stack Week, with a focus on new products, features, and partnerships to continue growing Cloudflare’s developer platform. As part of Full Stack Week, we also hosted the Developer Speaker Series, bringing 12 speakers in the web dev community to our 24/7 online TV channel, Cloudflare TV. The talks covered topics across the web development ecosystem, which you can rewatch at any time.

We loved organizing the Developer Speaker Series last year. But as developers know far too well, our ecosystem changes rapidly: what may have been cutting edge back in November 2021 can be old news just a few months later in 2022. That’s what makes conferences and live speaking events so valuable: they serve as an up-to-date reference of best practices and future-facing developments in the industry. With that in mind, we're excited to announce a new edition of our Developer Speaker Series for 2022!

Check out the eleven expert web dev speakers, developers, and educators that we’ve invited to speak live on Cloudflare TV! Here are the talks you’ll be able to watch, starting tomorrow morning (May 9 at 09:00 PT):

Worth Reading: The State of fq_codel (and Bufferbloat)

Erik Auerswald sent me a pointer to a blog post by Dave Taht: The state of fq_codel and sch_cake worldwide. It’s so nice to see what a huge impact Dave made since he started the Bufferbloat project.

Hint: if you have no idea what Bufferbloat or fq_codel are, you REALLY SHOULD explore Dave’s web site.

Cisco Catalyst Stack Upgrade

Well… It will reboot your whole switch stack at once, In case you were wondering. But it has a neat feature of automatic rollback to the previous IOS XE version if something goes south with the newly upgraded switches. The same goes for non-stacked Cisco Catalyst C9200 and C9300 switches, but the question was, and the answer is hard to find if the stack would reload members sequentially or it would just reload all members at once. The answer is of course the least good option which makes the upgrade impossible without network outage even if other devices are connected

Controversial Reads 050722

In January a federal judge denied Facebook’s motion to dismiss the Federal Trade Commission’s amended complaint seeking to force the company to sell off Instagram and WhatsApp.

Tech companies earn staggering profits by targeting ads to us based on our online behavior. This incentivizes all online actors to collect as much of our behavioral information as possible, and then sell it to ad tech companies and the data brokers that service them.

And often, when doing business in these countries, company’s interests in revenue and profits conflict with America’s national security interests, a conflict that profit always seems to win.

European Union lawmakers voted today in favor of controversial measures to outlaw anonymous crypto transactions, a move the industry said would stifle innovation and invade privacy.

His story is sobering: “The pressure comes from both above and below. You’ve got the United States Senate basically saying: ‘Nice little social network you got there. Real shame for anything to happen to it.’… From below, you’ve got the employees and the tweet mobs and basically forming these boycotts and subjecting the management of the company to pressure.

Twitter founder Jack Dorsey would like you to know he too misses the early Continue reading

Worth Watching: Source Routing on the Edge (iNOG::14v)

Most large content providers use some sort of egress traffic engineering on edge web proxy/caching servers to optimize the end-user experience (avoid congested transit autonomous systems) and link utilization on egress links.

I was planning to write a blog post about the tricks they use for ages, and never found time to do it… but if you don’t mind watching a video, the Source Routing on the Edge presentation Oliver Herms had at iNOG::14v does a pretty good job explaining the concepts and a particular implementation.

BrandPost: The Future of SD-WAN, Post COVID-19

By: Gabriel Gomane, Senior Product Marketing Manager at Aruba, a Hewlett Packard Enterprise company.For organizations coming out of government-mandated restrictions as a result of the COVID-19 crisis, they have an opportunity to reimagine their respective digital transformation journeys and become more resilient for coping with constant business change. Of course, not all businesses have survived, or thrived, during the past two-plus years. However, each must chart their own course in how they continue to digitize pieces or entire business functions. Key to that digital transformation is SD-WAN, especially as organizations rebound and climb out of the crisis, a crisis that may come roaring back considering the continued threat of new variants and outbreaks across the globe. In the meantime, here are five trends influencing SD-WAN that organizations can leverage to future-proof the business.To read this article in full, please click here

Community Spotlight series: Calico Open Source user insights from Ana Shmygla and Josef Janda, Jamf

In this installment of the Calico Community Spotlight series, I interviewed Ana Shmyglya and Josef Janda, who both work for Jamf. Last year, Josef wrote Migrating CNI plugin from kube-router to Calico on Kops managed Kubernetes cluster, and I wanted to dive deeper into his and Ana’s experience based on that blog post. We mainly talked about their respective teams, their responsibilities, and the challenges they have faced whilst using Kubernetes.

Q: What are your current roles and primary responsibilities?

Ana: I work in the Platform team. This basically means I am responsible for a team that maintains the core infrastructure, which includes the Kubernetes clusters that we run. We also own the underlying CNI of the clusters.

Josef: I work as a DevOps engineer on the team that maintains the internal development tools and other systems connected to the software delivery life cycle process.

Q: What orchestrator(s) have you been using?

Josef: We use Kubernetes. That’s basically the only orchestrator in our company.

Ana: Same for us as well, it’s Kubernetes across the company.

Q: What cloud infrastructure(s) has been part of your projects?

Ana: We use a couple of different providers, including AWS, but we only run Continue reading

Friday Thoughts on the Full Stack

It’s been a great week at Networking Field Day 28 this week with some great presentations and even better discussions outside of the room. We recorded a couple of great podcasts around some fun topics, including the Full Stack Engineer.

Some random thoughts about that here before we publish the episode of the On-Premise IT Roundtable in the coming weeks:

• Why do you need a full stack person in IT? Isn’t the point to have people that are specialized?
• Why does no one tell the developers they need to get IT skills? Why is it more important for the infrastructure team to learn how to code?
• We see full stack doctors, which are general practitioners. Why are there no full stack lawyers or full stack accountants?
• If the point of having a full stack understanding is about growing non-tech skills why not just say that instead?
• There’s value in having someone that knows a little bit about everything but not too much. But that value is in having them in a supervisor role instead of an operations or engineering role. Do you want the full stack doctor doing brain surgery? or do you want him to refer you to a Continue reading

Weekend Reads 050622

Video meetings dampen brainstorming because we are so hyper-focused on the face in that box that we don’t let our eyes and minds wander as much, a new study found.

Have you recently been on a video confefence call, hit the “mute” button and then offered up some nasty comments about a client or a colleague — or even the boss?

Comcast and other broadband providers are utilizing 10G technology in their quest to deliver “multigigabit symmetrical speeds” to the consumer market.

Yet, simultaneously, AI has been touted as both a panacea to virtually any problem in any field, as well as the source of humankind’s demise. “AI will push us to boundless innovation,” “AI will go rogue,” – across the industry, there remains a mix of skepticism and fear on how AI will specifically impact us as individuals.

It’s not often we can say this, but 2022 is shaping up to be an exciting time in information governance, especially for those interested in compliance and compliance frameworks.

Janczewski thought again of the investigative method that had brought them there like a digital divining rod, revealing a hidden layer of illicit connections underlying the visible world. He hoped, not for Continue reading

The Cloudflare Bug Bounty program and Cloudflare Pages

The Cloudflare Pages team recently collaborated closely with security researchers at Assetnote through our Public Bug Bounty. Throughout the process we found and have fully patched vulnerabilities discovered in Cloudflare Pages. You can read their detailed write-up here. There is no outstanding risk to Pages customers. In this post we share information about the research that could help others make their infrastructure more secure, and also highlight our bug bounty program that helps to make our product more secure.

Cloudflare cares deeply about security and protecting our users and customers — in fact, it’s a big part of the reason we’re here. But how does this manifest in terms of how we run our business? There are a number of ways. One very important prong of this is our bug bounty program that facilitates and rewards security researchers for their collaboration with us.

But we don’t just fix the security issues we learn about — in order to build trust with our customers and the community more broadly, we are transparent about incidents and bugs that we find.

Recently, we worked with a group of researchers on improving the security of Cloudflare Pages. This collaboration resulted in several security vulnerability Continue reading

Why I joined Cloudflare in Latin America

This post is also available in Español, Português.

I am excited to announce that I recently joined Cloudflare as Vice President and Managing Director for Latin America. As many of you reading this likely already know, Cloudflare is on a mission to help build a better Internet. And that’s a big part as to why I joined this team — to contribute to this in Latin America specifically and interconnect all across the world. Cloudflare has had a strong presence in Latin America for years. First investing in the region back in 2014, when it expanded its network into Latin America to be closest to the users here — to provide even faster and reliable connections without compromising security. Over the past couple of years, our reliance on the Internet has increased, and Latin America is the fourth largest region in terms of online users globally. You can see how this makes Cloudflare’s mission even more important and presents a significant opportunity in Latin America.
