I would say, if you have enough resources, like time, expertise etc you can set your own cluster. It will be some effort to maintain and manage it though once you have set it up. Managed clusters are obviously faster and easier to set up and great for smaller companies and definitely good fit for private projects. You will have some level of lock-in though.
Love you Nana... ❤️❤️❤️You are hot wana mail you and call you ...I m from india ...my mail id is 5canvin108@gmail.com 9515114375
In the beginning of the example cluster setup there are 2 master nodes where at least 3 are recommended
Hi Nana. I just started my DevOps career a few months ago and I must say, your videos are saving my life. I'm already spreading the word about your videos because I really hope they take you where you deserve. Great content and you are such an amazing explainer! You're helping me SO MUCH.
Thank you and I hope you keep creating such great content and helping other people understand complex concepts in a simple way. I'll surely always be a supporter :)
You're welcome, and thank you for this great feedback Renato! 🙂 I'm really glad my videos are so helpful! And especially that you spread the word, thanks :)
@Hi Chem I mainly learn from videos and working on real projects at work or for own projects
Her videos don't even have ads on them.

A service is like a load balancer, takes the request going to an application and forwards it to one of the pods in a node running that application.
Kube proxy is what forwards the requests from services to pods, and kube proxy is running on each node
The load balancer (service) routes the request to the closer node running the service (to avoid network overhead)
Etcd only runs on master nodes
We can have more than one master node. In that case etcd is a distributed key value store replicated across the master nodes.
Kubernetes made easy. After reading chunks of notes n listening to other video lectures, i ended up piling junks of confusion in my memory. Time n energies have been wasted. Ur lecture has delivered me and given me a renewed spirit of understanding on this subject. I must say, this is the first place to start before starting anything with kubernetes. Please, spread the news.
Wow, this is really great to hear! Will appreciate your support as well in spreading the word about my videos 😊
This so far the best explanation I came across on the internet about the k8s cluster and it's master/worker nodes. Thank you.
Wow that's great! Please share the video, would be very helpful for me :)
Thank you Nana, you probably have some of the best quality videos on Kubernetes
The way you explain things from basics to advanced is really so awesome! You are doing a great job. Thank you for all your hard work :)
Your channel is a pure gem, YOU’RE a gem too Nana. Thank you so much for all your work. Best wishes.
This video is even better than the training I bought online. It makes everything clear and summarizes all the key information. Thank you!
Thank you! Very clear and straightforward, which, with a tool as complex as Kubernetes, makes it very easy to understand.
Every time I have any doubt or want to recall any concept this quick video helps in great way.
Kudos to Nana for such an amazing videos on devops ~!
From a Certified CKAD, CKA expert, this is by far the best explanation of the kubernetes architecture !
nana i am your big fan .... your video are our lifelines..... love from India
@TechWorld ......Thankyou for providing such a valuable courses free of cost on utube. nicely explained.
Very clear and to the point. You are my go to channel if I want to quickly understand something in Devops
Randomly searching for kubernetes videos as I just started learning Kubernetes...and I end up here...such a great and simplified stuff...keep up all the good work and hope you get/reach what you deserve
so clear and easy to understand, as a visual learner this has been extremely helpful, thank you!
Thanks a lot Marc!
I am just a developer but somehow also involved in the architecture of my next project at my company (which is a chance I was waiting for). And that one uses k8s heavily. Those clips are my lifesaver. Thanks Nana.
I can't believe how easy you made understanding k8s to me..your graphical illustrations are just perfect..i was just looking for random tech videos and halfway through this video I subscribed your channel
So easily explained and with great clarity. You are a GEM 💎and a great inspiration. The animations are something that makes you very different and special. Thanks a lot Mrs.Nana for taking the pain to put those efforts in. Highly appreciated.👏👏👏👌👌👌
This so far the best explanation. Thanks
a very clear explanation about K8S...
Like the way you articulate and your presentation too is impeccable, love your slides, crisp clear and to the point. Appreciate your efforts on making such videos, No video did explain about Kubernetes to this extent, way to go!!! Keep up the good work.
Excellent video in easy , concise , descriptive fashion .
You are the best among all. I have good understanding of the k8s cluster after watching this video.
Wow, Awesome is an understatement. THANK YOU for the clear explanation.
Crystal clear explanation, thank you so much Nana
Simply love d way u explains... Thank you Nana
Hi nana,
I have been watching your videos for Kubernetes and I should say that this is the best way explained by anyone. I also want to tell you that many people say they choose Kubernetes over docker due to the complexity when your application grows big, but there aren't any videos on that part. My request is can you make a real-time video on what challenges we face when our application grows big, which led many people to choose Kubernetes over docker. This should help many people understand in real-time, why the shift has happened.
Cheers
Thank you Nana for such a great explanation and video. I have been working on changing my careers to DevOps and despite all the complex tools, K8s is been the most difficult one for me to understand. I have watched multiple videos and resources to understand kubernetes but this video just made my concepts so much clearer. Your videos are really helping me a lot while I am studying to change my career path to DevOps. Thanks so much, I hope you keep making videos and help others :)
Your videos are nothing less then Tom Cruise movies😇👍😇
You saved my time and provided the best quality content.... Thankyou 💯

Many thanks for the great content! Really helpful. I bought an online kubernetese course a while ago, and I have to admit your way of explaining concepts is way better.
Could you please recommend videos that would guide me through the installation of kubernetese on my on-premises environment?
I mean resources that are similar to your style.
Thanks in advance.
Great Video
Thank you. 🙂
amazing!
