VSHN.timer #104: SLA, SRE, eBPF, QoS, and Other Acronyms

16. Aug 2021

Welcome to another VSHN.timer! Every Monday, 5 links related to Kubernetes, OpenShift, CI / CD, and DevOps; all stuff coming out of our own chat system, making us think, laugh, or simply work better.

This week we’re going to talk about the most recent buzzwords trends in the field of Cloud Native app availability and reliability.

1. Remember when in 1999 the Pentagon classified the PowerMac G4 as a classified weapon and blocked Apple from exporting it? Times have changed, tech has evolved, and nowadays the NSA is worried about Kubernetes, to the point of publishing a hardening guide. Let’s keep the list of Kubernetes horror stories as short as possible.

2. When Facebook, Netflix, Microsoft, and Isovalent come together and start a foundation under the umbrella of the Linux Foundation, you know that something important is brewing: eBPF, a new concept we’re probably going to hear a lot about in the next decade. Our friends at Puzzle ITC are organizing a fantastic event next Monday about eBPF and Cilium with Priyanka Sharma & Liz Rice from the CNCF, and Thomas Graf from Isovalent. Won’t miss this one.


3. How to make sure your service remains available when you have millions of users? The engineering team at WeTransfer wanted to enable Single Sign-On across all of their products using Auth0, but without disrupting their 80 million users. And they did it!


4. DevOps, SRE, Platform Engineering, are concepts often used together in job descriptions, but it isn’t always clear how they relate to (or differ from) one another. Ivan Velichko expanded on these thoughts in his blog, highlighting major characteristics and common misunderstandings from a personal perspective.


5. Speaking about SLAs, here’s a nice reminder by Matt Rickard about the basic service reliability math any of us should know about. Actually, his whole blog is awesome and you should subscribe to it right away.


What guidelines do you follow to protect your clusters? Does your job match the descriptions of DevOps, SRE, or Platform Engineering? Would you like to share some Kubernetes QoS tips and tricks with the community? Get in touch with us, and see you next week for another edition of VSHN.timer.
