Announcing Foundation DNS — Cloudflare’s new premium DNS offering

Today, we’re announcing Foundation DNS, Cloudflare’s new premium DNS offering that provides unparalleled reliability, supreme performance and is able to meet the most complex requirements of infrastructure teams.

Let’s talk money first

When you’re signing an enterprise DNS deal, usually DNS providers request three inputs from you in order to generate a quote:

  • Number of zones
  • Total DNS queries per month
  • Total DNS records across all zones

Some are considerably more complicated and many have pricing calculators or opaque “Contact Us” pricing. Planning a budget around how you may grow brings unnecessary complexity, and we think we can do better. Why not make this even simpler? Here you go: We decided to charge Foundation DNS based on a single input for our enterprise customers: Total DNS queries per month. This way, we expect to save companies money and even more importantly, remove complexity from their DNS bill.

And don’t worry, just like the rest of our products, DDoS mitigation is still unmetered. There won’t be any hidden overage fees in case your nameservers are DDoS’d or the number of DNS queries exceeds your quota for a month or two.

Why is DNS so important?

Helping You Benefit from our Pluggable eBPF Data Plane – Introducing the New Calico eBPF Data Plane Certification

Why Create a Course About Calico’s eBPF Data Plane?

Calico is the industry standard for Kubernetes networking and security. It offers a proven platform for your workloads across a huge range of environments, including cloud, hybrid, and on-premises. 

Calico has had a high-quality, production-ready, performant, eBPF data plane option for some time!

However, although many users are deploying it in production and benefitting, we still sometimes see users who don’t know that Calico has an eBPF data plane or feel confident deploying it, and:

  • Don’t understand the benefits of Calico’s pluggable architecture
  • Don’t fully understand what eBPF is
  • Don’t know that Calico has an eBPF data plane
  • Don’t understand why it is not the default Calico data plane or best choice
  • Don’t feel confident to deploy the Calico eBPF data plane

We created the new CCO-L2-EBPF (Certified Calico Operator: eBPF) course specifically to address these points. The course will help you to understand the strengths of eBPF and when it is, or is not, the right choice. It will also help you see how easy it is to deploy the Calico eBPF data plane if you have made the choice that it is right for you and your cluster.

Using whois/jwhois on Linux

The whois and jwhois commands allow you to retrieve a lot of information on Internet domains--likely a lot more than you might imagine. Here's how these commands work and how they can be useful.To get started, you probably already use nslookup to check on domain names. When you do, you'll see output like this:$ nslookup networkworld.com Server: 127.0.0.53 Address: 127.0.0.53#53 Non-authoritative answer: Name: networkworld.com Address: 151.101.2.165 Name: networkworld.com Address: 151.101.66.165 Name: networkworld.com Address: 151.101.194.165 Name: networkworld.com Address: 151.101.130.165 The nslookup command queries name servers, so its output provides IP addresses for the queried domain and verifies the domain name is valid, but whois commands provide extensive details on the domain registration, domain status, responsible organizations, their locations, etc., giving you a lot more insight into domains.To read this article in full, please click here

Journalists: stop selling NFTs that you don’t understand

The reason you don't really understand NFTs is because the journalists describing them to you don't understand them, either. We can see that when they attempt to sell an NFT as part of their stories (e.g. AP and NYTimes). They get important details wrong.

The latest is Reason.com magazine selling an NFT. As libertarians, you'd think at least they'd get the technical details right. But they didn't. Instead of selling an NFT of the artwork, it's just an NFT of a URL. The URL points to OpenSea, which is known to remove artwork from its site (such as in response to DMCA takedown requests).

If you buy that Reason.com NFT, what you'll actually get is a token pointing to:

https://api.opensea.io/api/v1/metadata/0x495f947276749Ce646f68AC8c248420045cb7b5e/0x1F907774A05F9CD08975EBF7BF56BB4FF0A4EAF0000000000000060000000001

This is just the metadata, which in turn contains a link to the claimed artwork:

https://lh3.googleusercontent.com/8Q2OGcPuODtCxbTmlf3epFGOqbfCbs4fXZ2RcIMnLpRdTaYHgqKArk7uETRdSZmpRAFsNE8KB4sFJx6czKE5cBKB1pa7ovc4wBUdqQ

If either OpenSea or Google removes the linked content, then any connection between the NFT and the artwork disappears.

It doesn't have to be this way. The correct way to do NFT artwork is to point to a "hash" instead which uniquely identifies the work regardless of where it's located. That $69 million Beeple piece was Continue reading

Is SONiC Right for Your Data Center and Private Cloud Network?

Many data center operators are interested in bringing the benefits of hyperscaler technologies to on-prem data centers. One of these technologies is SONiC, an open source network operating system that is being advanced under the auspices of the Open Compute Project (OCP). There are a number of questions that enterprises, communication service providers and tier 2 cloud service providers need to ask themselves to understand if SONiC is a good choice for their on-prem data center and private cloud networks.

What is SONiC?

SONiC, which stands for “Software for Open Networking in the Cloud,” is a network operating system originally designed by Microsoft for their data center networks. Microsoft was frustrated with the overly complex operating systems provided by vendors like Cisco, Juniper and Arista that included many features that Microsoft simply did not need for their Azure cloud network. Thus, SONiC was built by Microsoft in a completely modular way based on running networking functions in containers so components could be added or removed as a mechanism to build a lean, optimized OS that only contained the essential features to run the Microsoft Azure cloud network. They also developed the Switch Abstraction Interface (SAI) with a goal of enabling Continue reading

APIs pose the latest threat of networking-vendor lock-in

In my surveys of enterprises, the number worried about vendor lock-in has hovered around 90% for 30 years.  When you ask enterprises how they avoid it, they respond “standard interfaces” or “open-source”. Even today, the percentage who include “managing APIs” in their list of lock-in avoidance measures is in the statistical noise level, but APIs are perhaps the fastest-growing lock-in problem today, and they’re surely going to become a major problem in the future.API stands for “application programming interface”, but the term is broadly used in software today to describe the interfaces between all the software components used in an application, a cloud, or even a network. APIs let pieces of software talk with each other, and they’re essential in every situation where software components rather than hardware devices are connected. What’s creating a challenge in lock-in from APIs today is the fact that networking is shifting more to software, which means it’s shifting to a model where APIs are just as important as those standard interfaces, and enterprises aren’t tracking that important shift.To read this article in full, please click here

FTC investigation of Nvidia/Arm deal will only hurt Arm

The proposed Nvidia-Arm merger had another roadblock thrown in front of it when the US Federal Trade Commission’s filed a lawsuit objecting to the $40 billion deal last week.The acquisition met with almost immediate opposition from UK entities when it was announced in September 2020. Now, 15 months laster the FTC weighs in and has set an administrative trial for Aug. 9, 2022.“Tomorrow’s technologies depend on preserving today’s competitive, cutting-edge chip markets,” said Holly Vedova, director of the FTC’s Bureau of Competition in a statement. “This proposed deal would distort Arm’s incentives in chip markets and allow the combined firm to unfairly undermine Nvidia’s rivals.”To read this article in full, please click here
