Heavy Networking 631: Saying No
On today's Heavy Networking we talk about why it's important to say "No" when someone tries to put more work on you than you can handle. Guest Tom Hollingsworth wrote a controversial blog post entitled “No Is A Complete Sentence” about how to say "No," to even when it's hard to do. We talk about the nuances of this stance, the risks you take when you do, time management, balancing workloads, and more.

Wendy Komadina: No one excited me more than Cloudflare, so I joined.
I joined Cloudflare in March to lead Partnerships & Alliances for Asia Pacific, Japan, and China (APJC). In the last month I’ve been asked many times: “Why Cloudflare?” I’ll be honest, I’ve had opportunities to join other technology companies, but no other organization excited me more than Cloudflare. So I jumped. And I couldn’t be more thrilled for the opportunity to build a strong partner ecosystem for APJC.
When I considered joining Cloudflare, I recall consistently reading the message around “Helping to Build a Better Internet”. At first those words didn’t connect with me, but they sounded like an important mission.
I did my research and read analyst reports to learn about Cloudflare's market position, and then it dawned on me, Cloudflare is leading a transformation. Taking traditional on-premise networking and security hardware and building a transformational cloud-based solution, so customers don’t need to worry about which company supplied their kit. I was excited to learn that Cloudflare customers can simply access the vast global network that has been designed to make everything that customers connect to on the Internet secure, private, fast, and reliable. So hasn’t this been done before? For compute and storage that transformation is almost Continue reading
Is Sensing the Next Killer App for Wi-Fi?
Wi-Fi Sensing technology can sense the disruption of the signal and use the information to determine the size, speed, and location of the disruption.The Dangers of 5G Technology for Airplanes
The next generation of wireless technology, 5G, is set to revolutionize the way we live and work. 5G works by using higher frequency signals than previous generations of wireless technology. These higher frequency signals are more easily absorbed by obstacles like buildings and trees, which can cause interference.
What is 5G technology and how does it work
5G uses a higher frequency of radio waves than previous generations of wireless technology. This means that 5G can carry more data and achieve higher speeds than 4G. However, it also means that 5G signals don’t travel as far as 4G signals and are more easily blocked by obstacles like walls and trees.
To overcome this challenge, 5G networks use a process called beamforming. Beamforming involves using multiple antennas to focus the signal in a specific direction. This allows the signal to travel further and Penetrate obstacles more easily. As a result, beamforming is a key technology that makes 5G possible.
In addition to beamforming, 5G networks also rely on a process called massive MIMO (multiple-input, multiple-output). Massive MIMO involves using dozens or even hundreds of antennas to send and receive data. This allows 5G networks to handle large amounts of traffic Continue reading
Monitoring our monitoring: how we validate our Prometheus alert rules
Background
We use Prometheus as our core monitoring system. We’ve been heavy Prometheus users since 2017 when we migrated off our previous monitoring system which used a customized Nagios setup. Despite growing our infrastructure a lot, adding tons of new products and learning some hard lessons about operating Prometheus at scale, our original architecture of Prometheus (see Monitoring Cloudflare's Planet-Scale Edge Network with Prometheus for an in depth walk through) remains virtually unchanged, proving that Prometheus is a solid foundation for building observability into your services.
One of the key responsibilities of Prometheus is to alert us when something goes wrong and in this blog post we’ll talk about how we make those alerts more reliable - and we’ll introduce an open source tool we’ve developed to help us with that, and share how you can use it too. If you’re not familiar with Prometheus you might want to start by watching this video to better understand the topic we’ll be covering here.
Prometheus works by collecting metrics from our services and storing those metrics inside its database, called TSDB. We can then query these metrics using Prometheus query language called PromQL using ad-hoc queries (for example to power Grafana Continue reading
