The DNS protocol needs refreshing but a global, distributed database is not easy to change. The folks leading the DNS architecture are making small but substantial changes once per year. There is a non-zero but small risk that something will break for some people. This year they are addressing DNS Fragmentation on UDP and required […]
Security automation is an area that encompasses different practices, such as investigation & response, security compliance, hardening, etc. While security is a prominent topic now more than ever, all of these activities also greatly benefit from automation.

Since the launch of Cloudflare Stream, our customers have been asking for a programmatic way to add watermarks to their videos. We built the Watermarks API to support a wide range of use cases: from customers who simply want to tell Stream “can you put this watermark image to the top right of my video?” to customers with more detailed asks such as “can you put this watermark image in a way it doesn’t take up more than 10% of the original video and with 20% opacity?” All that and more is now available at no additional cost through the Watermarks API.
Cloudflare Stream provides out-of-the-box video infrastructure so developers can bring their app ideas to market faster. While building a video streaming app, developers must ask themselves questions like
Cloudflare Stream is a single product that handles video encoding, storage, delivery and presentation (with the Stream Player.) Stream lets developers launch their ideas Continue reading
It hadn’t occurred to me that having Dual SIMs in a smartphone has hidden aspects of complexity. In this slide, having multiple SIMs means thinking about activity – are both SIMs active at all times ? If so, are you willing to incur the battery and product penalty to have dual radios operating simultaneously. Or […]
Earlier this year, Pete Lumbis returned as an ipSpace.net webinar guest speaker with a great presentation describing data center switching ASICs from the perspective of networking engineers. After a brief intro, he started with ASIC Basics… a topic which generated a 25-minute Q&A session.
In part I of this series, we learned about creating Docker images using a Dockerfile, tagging our images and managing images. Next we took a look at running containers, publishing ports, and running containers in detached mode. We then learned about managing containers by starting, stopping and restarting them. We also looked at naming our containers so they are more easily identifiable.
In this post, we’ll focus on setting up our local development environment. First, we’ll take a look at running a database in a container and how we use volumes and networking to persist our data and allow our application to talk with the database. Then we’ll pull everything together into a compose file which will allow us to setup and run a local development environment with one command. Finally, we’ll take a look at connecting a debugger to our application running inside a container.
Instead of downloading MongoDB, installing, configuring and then running the Mongo database as a service. We can use the Docker Official Image for MongoDB and run it in a container.
Before we run MongoDB in a container, we want to create a couple of volumes that Docker can manage to Continue reading
The appetite for compute capacity, and presumably also for storage and networking capacity, in the datacenter of the world might be waning in some sectors of the economy, but thanks to the voracious hunger of the hyperscalers and cloud builders and more than a few large enterprises that need to do more, not less, computing in the face of the coronavirus pandemic, server sales are now consistently at the levels we saw way back in the Dot-Com Boom more than twenty years ago. …
Server Hunger Is Stronger Than Economic Uncertainty was written by Timothy Prickett Morgan at The Next Platform.
Discussions about networking in a work-from-home world often focus on employees and endpoints, but how can network administrators do more than just keep the lights on if they can’t go to the data center? Maintaining what exists isn’t enough, especially as the entire world is redefining the future of work. Organizations need to be able to adapt to change, so how is that possible when administrators can’t go hands on?
There are any number of remote administration options available today, and any number of ways to compare them. Deciding between them is all about finding the right balance between cost, capability, and the labor intensity of implementation. In other words, they’re subject to all of the same considerations as any other technology implementation.
To dispense with the network administration 101 portion of the discussion*, yes, networking is mostly a matter of remote administration anyway. If you can remote into something that has access to the management network, you can use SSH, HTTPS, or what-have-you to administer networks just as you would if you were in the office. That’s maintenance, not change.
Accomplishing change remotely and at scale requires automation and orchestration. In practice, this is heavily dependent upon virtualization and/or Continue reading
Tigera serves the networking and policy enforcement needs of more than 150,000 Kubernetes clusters across the globe and supports two product lines: open source Calico, and Calico Enterprise. Our development team is constantly running smoke, system, unit, and functional verification tests, as well as all our E2Es for these products. Our CI pipelines form an extremely important aspect of the overall IT infrastructure and enable us to test our products and catch bugs before release.
We eventually reached a point where we needed to adopt a complete continuous integration and delivery architecture to maintain our development velocity, from code push to Kubernetes. We decided to adopt the hosted CI solution from Semaphore as an integral part of our workflow. Our test rigs on Semaphore ensure that the product is tested on three Kubernetes versions on seven different platforms, including Kubeadm, GKE, EKS, AKS, OpenShift, Rancher, and Kops. As a result, a typical pipeline can have up to 100 jobs distributed over various stages. We also have different pipelines to test our code and build Docker images for it.
Here’s a run for one of the components of our open source offering: All the Continue reading

In the list of diseases that can affect your brain, Alzheimer’s disease is a critical one. From it not only affects the biology of the brain, it also affects the personality of the person. That is why it is necessary to talk about Alzheimer’s, because talking about this disease helps create awareness about brain health. On World Alzheimer’s Day, Sept. 21, 2020, talking about it will help create a sense of seriousness and importance.
There are some diseases that are inevitable. That means that they cannot be stopped from occurring, but what an individual can do is make sure that you keep your brain health better and active.
By sleeping better, you are making sure that your brain is getting the right rest. This means that you make sure that you are being provided with a situation where you are resting and your brain is working actively to make sure that it keeps you and your body healthy. That is why a good night’s sleep can help not only elevate your mood but also help keep you healthy and strong.
By eating healthy and well, you will Continue reading
Cloudflare powers cdnjs, an open-source project that accelerates websites by delivering popular JavaScript libraries and resources via Cloudflare’s network. Since our major update in December, we focused on remodelling cdnjs for scalability and resilience. Today, we are excited to announce how Cloudflare delivers cdnjs—a migration to a serverless infrastructure using Cloudflare Workers and its distributed key-value store Workers KV!
For those unfamiliar, cdnjs is an acronym describing a Content Delivery Network (CDN) for JavaScript (JS). A CDN simply refers to a geographically distributed network of servers that provide Internet content, whether it is memes, cat videos, or HTML pages. In our case, the CDN refers to Cloudflare’s ever expanding network of over 200 globally distributed data centers.
And here’s why this is relevant to you: it makes page load times lightning-fast. Virtually every website you visit needs to fetch JS libraries in order to load, including this one. Let’s say you visit a Sydney-based website that contains a local file from jQuery, a popular library found in 76.2% of websites. If you are located in New York, you may notice a delay, as it can easily exceed 300ms to fetch the file—not to mention Continue reading
