Kubernetes Design Principles: Understand the Why - Saad Ali, Google
Kubernetes is quickly becoming indispensable for managing and deploying workloads on distributed systems across both cloud and on-prem environments. While most people are now familiar with how to use Kubernetes, few are aware of the “why” behind it? Why does the Kubernetes API look the way it does? Why do Kubernetes components only interact with each other through the Kubernetes API? Why is there a PersistentVolumeClaim object when you could easily reference a volume directly from a pod? To answer these questions and help you develop a deeper understanding of Kubernetes, this talk exposes the principles underpinning the design of Kubernetes.

The single best video on KZbin that explicates the Kubernetes design philosophy. Very helpful.

[@mahmudulhaque6744]

Principles mentioned: 1. Kubernetes APIs are declarative rather than imperative. 2. The Kubernetes control plane is transparent. There are no hidden internal APIs. 3. Meet the user where they are. 4. Workload portability.

also at 30:53, great presentation! I would like to add some discussion at the end to reflect those points: 1. Self-healing, extensible 2. Immutable. transparent 3. Ease of adoption 4. Cloud/Cluster agnostic - separation of concern, easy for maintenance

[@gshankarshanmugam]

Excellent presentation.. Hats off!! Very precise very detailed.. If one is architect he understand each and evey word in depth... His explaination is very simple but huge is meaning microservice deployement to containerization

[@jeffreyprato]

Whole-to-parts learning, thank you. Can’t go shopping without a basket!

[@eswaraakurathi8647]

Excellent explanation and much-needed insights about Kubernetes components

[@TheStuzenz]

Thanks Saad, I enjoyed the presentation - a good starting primer as I get into Kubernetes

[@alexk6745]

Great video thanks. I wish I saw this 3 years back

[@prateeksrivastava7948]

Yup. This video is having very less views for the content and presentation it has to offer - watching it will definitely fill in the gaps in k8s understanding for anyone.

[@Nerdmor]

Amazing presentation

[@MrRavihr]

Very informative! Thank you

[@arifkhan9]

Excellent talk on kubernetes. I’m new to this tech, coming from Hadoop world, this talk helped me to get understanding of the internals

[@athumma9028]

Awesome presentation. Very informative

[@ghassenbenmansour3159]

Kubernetes is the Holy Grail of modern software design patterns.

[@ToniMenzel82]

It more sounds to me that Kubernetes just rebranded OSGi principles and used containers instead of bundles as primitives. Its a great achievement by k8s but they could at least attribute where they borrowed the core concepts from.

[@karimmanaouil7278]

@@ToniMenzel82 Kubernetes is an application deployment system that was inspired from Borg. It has nothing to do with OSGi.

[@ToniMenzel82]

@@karimmanaouil7278 If you know OSGi then you'd understand the conceptual similarities I was pointing out. My comment (2yrs) ago was more on the ironic side. Similarities are because concepts such as a declarative api with extensible control plane (whiteboard pattern) are good ideas. Both OSGi and Kubernetes implemented them. At different scales: one is for orchestrating java components (through services & bundles) and the other for containers. Just wanted to make that clear. No worries.

[@karimmanaouil7278]

@@ToniMenzel82 makes sense what you said and I totally agree. My previous reply was addressing the part where you said that the k8s authors should attribute OSGi because they got the concepts from there, and I just wanted to point out that they probably had no idea about OSGi. Many concepts gets rediscovered independently all the time in software engineering, but in different contexts.

Thanks Saad Ali

Great talk, excellent presentation!

Very informative!

[@dealscart]

Excellent 👌

[@ddg170]

amazing!

[@JiffyCakes]

One thing missing from this presentation: why k8s in the first place? It took me a while to answer this: horizontal scaling. How do you use up more resources by creating replicas of your software and running them on different machines instead of having a single copy of your software running on a beefier VM. This actually is a slight paradigm-shift from the traditional "one executable" model.

nice stuff

Thanks

Thank you’re

[@maheshbangalore8962]

Good one,,

[@michaelasin6050]

Damn, the talk makes k8s so obvious

[@mwloos1]

Is a backup solution such as Kasten highly sought after for stateful workloads since volume plug-ins exist?

Slave? No more please. Kubernetes uses worker instead. This is the progress.

please stop using the term slave or concentration camp or internment camp or 911 towers as descriptive terms in our field.

Fuck you!!! you will see what you have in your heart. There is racial discrimination in your mother's heart, and everything is racial discrimination. The pure land of technology is all dirty by you hybrids! ! !

[@williamg5309]

Do you seriously believe that pushing for this will serve BLM cause? My impression so far is that it only makes you and the cause seem ridiculous. You won't get even by changing the language in totally irrelevant areas. You'll only make things and root causes _harder_ to see next time this happens.
