Hello Nana, Appreciate your efforts in putting up this course. Can you also provide a section here on pre-requisites to learn Kubernetes? Is this for a techie or even a non-techie can take this course? These info will be very helpful.
Hello, Nana , Thanks for your contribution to the community, I am in love with your videos

I'm watching over Yt Vanced, sorry
Does skipping ads makes difference?

I like how you explain things. The problem-solution paradigm you use to explain every idea/concept is so efficient because it fits our why-questions-oriented minds. Thank you Nana for this very helpful video :)
5 other Kubernetes videos washed over the top of me, while Nana's organization & continuous visual aids made learning Kubernetes not only attainable but an enjoyable experience...
I believe a big difference is her knowledge & understanding of the intricacies & their correlation becomes clear with her ability to break down the concepts & infor into easily digestible pieces. Thank you very much!
Nana , amazingly put together , very clearly explained , you rock !
