More than a decade ago I published tons of materials on a web site that eventually disappeared into digital nirvana, leaving heaps of broken links on my blog. I decided to clean up those links, and managed to save some of the vanished content from the Internet Archive:

The idea of serverless is to allow developers to focus on writing code rather than operations — the hardest of which is scaling applications. A predictably great deal of traffic that flows through Cloudflare's network every year is Black Friday. As John wrote at the end of last year, Black Friday is the Internet's biggest online shopping day. In a past case study, we talked about how Cordial, a marketing automation platform, used Cloudflare Workers to reduce their API server latency and handle the busiest shopping day of the year without breaking a sweat.
The ability to handle immense scale is well-trodden territory for us on the Cloudflare blog, but scale is not always the first thing developers think about when building an application — developer experience is likely to come first. And developer experience is something Workers does just as well; through Wrangler and APIs like Workers KV, Workers is an awesome place to hack on new projects.
Over the past few weeks, I've been working ona sample open-source e-commerce app for selling software, educational products, and bundles. Inspired by Humble Bundle, it's built entirely on Workers, and it integrates powerfully with all kinds of first-class modern Continue reading
In this week's IPv6 Buzz episode, Ed and Tom talk discuss the impact that service provider deployment of Carrier Grade NAT (CGN) has had on the overall adoption of IPv6. Our guests are Kevin Myers and Nick Russo. Kevin and Nick have both worked with CGN and IPv6, and Nick is designing an IPv6 training course on Pluralsight.

The Internet is for everyone – a critical lifeline that can uplift communities. But only if we go beyond Internet access and bridge the knowledge gap that continues to persist: the gap between those who have the knowledge and skills to use the Internet to empower themselves and their communities and those who don’t.
To address this divide, the Internet Society Foundation recently awarded over $1 million in digital skills development grants to eight innovative projects in Bangladesh, Colombia and Senegal. In its pilot year, the Strengthening Communities, Improving Lives and Livelihoods (SCILLS) grant programmeaims to expand economic growth, improve health outcomes, and increase educational opportunities by supporting individuals and communities to more knowledgeably and skillfully use the Internet.
The Internet Society Foundation was established in 2019 to support the positive difference the Internet can make to people everywhere. The Foundation awards grants to Internet Society Chapters/Special Interest Groups (SIGs) as well as nonprofit organizations and individuals dedicated to providing meaningful access to an open, globally-connected, secure, and trustworthy Internet for everyone.
Just recently we have started discussion about the tools about the performance troubleshooting in networks. One of the questions we were asked afterwards was, how to programatically get your public IP? Well, that is interesting one.

Can automation help with performance troubleshooting?
Yes, and that was a question we’ve started this blogpost with is about that. How can we rely the automation tools by troubleshooting? How can we get our IP to make any diagnostics? You will see some things right in this blogpost
Our network automation training has two faces: either live or self-paced. So you can choose yourself, what works better for you. On our side, we guide you from the foundation of the automation for the small networks till advanced automation use cases in big data centres, service providers, and clouds. You will lean how to structure the data using YANG modules, how to serialise it using JSON, XML, Protocol Continue reading
It’s amazing how far you can get if you keep doing something for a long-enough time. In a bit over 10 years (the initial versions of the earliest still-active webinars were created in October 2010), we accumulated over 300 hours of online content available with ipSpace.net subscription, plus another 130 hours of online course content.
Obviously I couldn’t have done that myself. Thanks a million to Irena who took over most of the day-to-day business a few years ago, dozens of authors, and thousands of subscribers who enabled us to make it all happen.

Cluster API is a topic I’ve discussed here in a number of posts. If you’re not already familiar with Cluster API (also known as CAPI), I’d encourage you to check out my introductory post on Cluster API first; you can also visit the official Cluster API site for more details. In this short post, I’m going to show you how to pause the reconciliation of Cluster API cluster objects, a task that may be necessary for a variety of reasons (including backing up the Cluster API objects in your management cluster).
Since CAPI leverages Kubernetes-style APIs to manage Kubernetes cluster lifecycle, the idea of reconciliation is very important—it’s a core Kubernetes concept that isn’t at all specific to CAPI. This article on level triggering and reconciliation in Kubernetes is a great article that helps explain reconciliation, as well as a lot of other key concepts about how Kubernetes works.
When reconciliation is active, the controllers involved in CAPI are constantly evaluating desired state and actual state, and then reconciling differences between the two. There may be times when you need to pause this reconciliation loop. Fortunately, CAPI makes this pretty easy: there is a paused field that allows users Continue reading
On today's Day Two Cloud we review announcements and make our observations of the KubeCon and CloudNativeCon North America 2020 virtual event. That includes a new Kubernetes certification, the results of a Cloud Native survey, the quality of technical sessions, and new product releases.

None of us can stop thinking about how 2020 has changed the way we go about our daily tasks. Going to school, going to the store, going out to eat — going anywhere at all. But now, for the first time, we are not even going to work! Everyone has been pushed to work from home. This change has a wide-ranging set of variables that need to be addressed, from the business limits on resources for connectivity to the employee’s limits on remote resources of space, privacy, and uninterrupted concentration.
The overnight reliance on remote, personal, shared services for connectivity from the worker to the corporation has forever put an end to the idea of a security perimeter. Zero Trust Architecture (ZTA) has moved from being an academic discussion to a persistent customer requests for solutions. This shift is furthered by the timely release of the US National Institute of Standards and Technology’s NIST Special Publication 800-207 ZTA Guide. At the same time, we now see numerous security industry vendorsclaiming their products will provide Zero Trust.
From working in unbelievable environments to dealing with unexpected bugs, the longer that you do networking for a career the more likely it is that you have a story or two from the trenches to share. Listening to other’s adventures can serve both as a cathartic release and as a warning for roads to leave untraveled. In today’s episode we talk with some experienced engineers about their stories. If nothing else, you as the listener can have some laughs at our expense. Enjoy!

Welcome to Technology Short Take #134! I’m publishing a bit early this time due to the Thanksgiving holiday in the US. So, for all my US readers, here’s some content to peruse while enjoying some turkey (or whatever you’re having this year). For my international readers, here’s some content to peruse while enjoying dramatically lower volumes of e-mail because the US is on holiday. See, something for everyone!
Networking
Isovalent—the company behind Cilium, the eBPF-powered networking solution for Kubernetes clusters—just launched with a $29M Series A round of funding. Cilium is good stuff, and the Isovalent team is chock-full of great people. Congrats, Isovalent team!
I’m glad to see this. Open source has become so critical to so many aspects of our computing infrastructure.
OpenCSPM looks like it could be quite a useful tool. I haven’t yet had time to dig in and get familiar with the details, but what I have seen so far looks good.
One of the great arts of software engineering is making updates and improvements to working systems without taking them offline. For some systems this can be rather easy, spin up a new web server or load balancer, redirect traffic and you’re done. For other systems, such as the core distributed data store which keeps millions of websites online, it’s a bit more of a challenge.
Quicksilver is the data store responsible for storing and distributing the billions of KV pairs used to configure the millions of sites and Internet services which use Cloudflare. In a previous post, we discussed why it was built and what it was replacing. Building it, however, was only a small part of the challenge. We needed to deploy it to production into a network which was designed to be fault tolerant and in which downtime was unacceptable.
We needed a way to deploy our new service seamlessly, and to roll back that deploy should something go wrong. Ultimately many, many, things did go wrong, and every bit of failure tolerance put into the system proved to be worth its weight in gold because none of this was visible to customers.
Adaptive applications are an inescapable evolution driven by the need to scale business that increasingly relies on the ability to keep applications fast, secure, and available.
