Kubernetes simply explained for beginners | in 15 mins

With this short video [What is Kubernetes](https://youtu.be/VnvRFRk_51k) I tried to give a concise but thorough overview of

* **What** **problems Kubernetes solves**? Or why is there a need for a container orchestration tool?
* **What features do** **container orchestration tools** offer?
* **Basic architecture**: Master-Slave nodes, Kubernetes processes
* **Basic concepts**: Pods, Containers, Services. What is the role of each?
* and lastly show an Example Configuration

In addition you can check out my video about [Docker vs Kubernetes vs Docker Swarm](https://youtu.be/9_s3h_GVzZc) in which I clarify the differences and similarities.

Thought it is helpful or interesting for some of you. So, happy watching 😊 Also appreciate any feedback!

  1. microservices and containers are not one and the same, this is really important. microservices are technology agnostic but very commonly utilising containerisation technology.

    also, Kubernetes does not guarantee high availability, it facilitates it if you want. what happens if you run a one node Kubernetes cluster and that one node dies? HA is a cluster configuration, not a given. also, Kubernetes does not deal with application performance whatsoever. imagine the scenario you have 200 very underpowered nodes all hosting one of your monolithic websites. does the fact that you got 200 nodes help performance? not a single bit. it just helps you deal with serving more customers your very slow website which can be interpreted as performance, but I wouldn’t say so.

    finally, Kubernetes does not deal with backup either, typically Kubernetes doesn’t really get involved with file storage at all, you just point it somewhere.

    the rest was really well explained and put together.

  2. So, should we be pronouncing it “Koo-ber-net-ees”, or “Koo-ber-naits”?

    Everyone at my workplace uses the first one, but the “k8s” abbreviation has me second-guessing that.
