Recap: KubeCon + CloudNativeCon NA 2023

Thanks to everyone who joined us in Chicago this month at KubeCon + CloudNativeCon NA 2023. We had a chance to have many meaningful conversations about Kubernetes and container security, the latest in the open source ecosystem, and of course—Calico! Here are some highlights from the conference.

Calico at KubeCon

We had a ton of visitors at our booth this year and were happy to catch up with old friends as well as meet new ones. Tech problems for business needs, such as how to provide fixed IPs to workloads for communication outside of the Kubernetes cluster instead of architectural debates about the underlying dataplane, was a popular topic of discussion. Another was runtime security at the workload level (default-deny/zero trust). The issue of visibility into workload communication at scale overlaid with effective security policies also came up often. We were all too happy to show how Calico can help!

Cruise Party

Those who joined us for our private cruise party enjoyed a guided architecture tour of the spectacular Chicago lakefront. The evening went swimmingly and offered our guests a chance to unwind and network while enjoying great food and an open bar, against a backdrop of glittering skyscrapers.

Cyber Week: Analyzing Internet traffic and e-commerce trends

Throughout the year, special events lead to changes in Internet traffic. We observed this with Thanksgiving in the US last week, where traffic dipped, and during periods like Black Friday (November 24, 2023) and Cyber Monday (November 27, 2023), where traffic spiked.

But how significant are these Cyber Week days on the Internet? Is it a global phenomenon? Does e-commerce interest peak on Black Friday or Cyber Monday, and are attacks increasing during this time? These questions are important to retailers and stakeholders around the world. At Cloudflare, we manage substantial traffic for our customers, which gives us a unique vantage from which to analyze traffic and attack patterns across large swaths of the Internet.

As we'll explore next, we observed varying trends. From a global perspective, there was a clear Internet traffic winner: Cyber Monday was the highest overall traffic day of 2023 (as it was for 2022), followed by Black Friday, and then Monday, November 21 from the same week. But zooming in, this pattern didn’t hold in some countries.

For this analysis, we examined anonymized samples of HTTP requests crossing our network, as well as DNS queries. Cloudflare's global data shows that peak request traffic occurred on Continue reading

HS059: Cognitive Load and Platforms

Our conversation begins with an exploration of the concept of cognitive load in relation to platforms. David, despite being an IT professional and not a psychiatrist, brought an intriguing perspective to the table. He emphasized how platforms, such as VMware, Kubernetes, and Cloud Foundry, are designed to remove effort from users, making it easier for... Read more »

AWS Adopts Arm V2 Cores For Expansive Graviton4 Server CPU

For more than a year, we have been expecting for Amazon Web Services to launch its Graviton4 processor for its homegrown servers at this year’s re:Invent, and lo and behold, chief executive officer Adam Selipsky rolled out the fourth generation in the Graviton CPU lineup – and the fifth iteration including last year’s overclocked Graviton3E processor aimed at HPC workloads – during his thrombosis-inducing keynote at the conference. …

Better debugging for Cloudflare Workers, now with breakpoints

Better debugging for Cloudflare Workers, now with breakpoints

As developers, we’ve all experienced times when our code doesn’t work like we expect it to. Whatever the root cause is, being able to quickly dive in, diagnose the problem, and ship a fix is invaluable.

If you’re developing with Cloudflare Workers, we provide many tools to help you debug your applications; from your local environment all the way into production. This additional insight helps save you time and resources and provides visibility into how your application actually works — which can help you optimize and refactor code even before it goes live.

In this post, we’ll explore some of the tools we currently offer, and do a deep dive into one specific area — breakpoint debugging — looking at not only how to use it, but how we recently implemented it in our runtime, workerd.

Available Debugging Tools

Logs

console.log. It might be the simplest tool for a developer to debug, but don’t underestimate it. Built into the Cloudflare runtime is node-like logging, which provides detailed, color-coded logs. Locally, you can view these logs in a terminal window, and they will look like this:

Outside local development, once your Worker is deployed, console.log statements are visible via Continue reading

DNS at IETF 118

The IETF met in Prague in the first week of November 2023, and, as usual there was a flurry of activity in the DNS-related Working groups. Here's a roundup of those DNS topics I found to be of interest at that meeting.

Steve Bray: Why I joined Cloudflare

Steve Bray: Why I joined Cloudflare.

I am excited to announce that I joined Cloudflare last month as Head of Australia & New Zealand, to continue to build on Cloudflare’s success in the region through extending our valuable relationships with our customers and partners.

My journey to Cloudflare

I’ve been fortunate over my 25-year career in the IT industry to have worked for some of the most recognised and innovative organisations such as Oracle, Salesforce, and Zendesk. It’s been exciting to be inside these businesses as they’ve taken new ideas about how software can be developed and delivered to solve real world problems for any organisation’s customers. I’ve learned a lot by being a part of the industry, but probably more importantly, I’ve learned the most from the smart, experienced, diverse groups of talented people that I’ve had the pleasure to work with in ANZ and across Asia Pacific. I have always been interested in the problems that organisations are trying to solve through technology — for example, responding to strategic challenges, reducing cost, improving revenue, reducing risk — and joining Cloudflare is an opportunity to stay focussed on addressing those critical issues with our customers and partners using Cloudflare’s innovative solutions.

So why Cloudflare?

Asking The Right Question About The Wireless Future

It wasn’t that long ago that I wrote a piece about how Wi-Fi 6E isn’t going to move the needle very much in terms of connectivity. I stand by my convictions that the technology is just too new and doesn’t provide a great impetus to force users to upgrade or augment systems that are already deployed. Thankfully, someone at the recent Mobility Field Day 10 went and did a great job of summarizing some of my objections in a much simpler way. Thanks to Nick Swiatecki for this amazing presentation:

He captured so many of my hesitations as he discussed the future of wireless connectivity. And he managed to expand on them perfectly!

New Isn’t Automatically Better

Any time I see someone telling me that Wi-Fi 7 is right around the corner and that we need to see what it brings I can’t help but laugh. There may be devices that have support for it right now, but as Nick points out in the above video, that’s only one part of the puzzle. We still have to wait for the clients and the regulatory bodies to catch up to the infrastructure technology. Could you imagine if we did the same Continue reading
