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

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

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?

Cloudflare named a leader in Forrester Edge Development Platforms Wave, Q4 2023

This post is also available in Español, Deutsch, Português, 日本語, 한국어.

Forrester has recognized Cloudflare as a leader in The Forrester Wave™: Edge Development Platforms, Q4 2023 with the top score in the current offering category.

According to the report by Principal Analyst, Devin Dickerson, “Cloudflare’s edge development platform provides the building blocks enterprises need to create full stack distributed applications and enables developers to take advantage of a globally distributed network of compute, storage and programmable security without being experts on CAP theorem.“

Over one million developers are building applications using the Developer Platform products including Workers, Pages, R2, KV, Queues, Durable Objects, D1, Stream, Images, and more. Developers can easily deploy highly distributed, full-stack applications using Cloudflare’s full suite of compute, storage, and developer services.

Workers make Cloudflare’s network programmable

“ A key strength of the platform is the interoperability with Cloudflare’s programmable global CDN combined with a deployment model that leverages intelligent workload placement.”
– The Forrester Wave™: Edge Development Platforms, Q4 2023

Workers run across Cloudflare’s global network, provide APIs to read from and write directly to the local cache, Continue reading

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

Can a Router Use the Default Route to Reach BGP Next Hops?

TL&DR: Yes.

Starting with RFC 4271, Route Resolvability Condition:

• A route without an outgoing interface is resolvable if its next hop is resolvable without recursively using the same route.
• A route with an outgoing interface is always considered resolvable.
• BGP routes can be resolved through routes with just a next hop or an outgoing interface.

Worth Reading: Network Automation with GitHub Actions

George Davitiani put together a lovely proof-of-concept using GitHub actions to deploy modified configurations to network devices. Even better, he documented the whole setup, and the way to reproduce it. I’m positive you’ll find a few ideas browsing through what he did.
