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.

[@chandhrrasekarseethamraju613]

Love you Nana... ❤️❤️❤️You are hot wana mail you and call you ...I m from india ...my mail id is [e-mail] 9515114375

[@tomaszszczodrowski8980]

In the beginning of the example cluster setup there are 2 master nodes where at least 3 are recommended

[@renatonunesmoraes1249]

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 :)

[@TechWorldwithNana]

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 :)

[@TechWorldwithNana]

@Hi Chem I mainly learn from videos and working on real projects at work or for own projects

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.

[@TechWorldwithNana]

Wow, this is really great to hear! Will appreciate your support as well in spreading the word about my videos 😊

[@amitsalunke1567]

This so far the best explanation I came across on the internet about the k8s cluster and it's master/worker nodes. Thank you.

[@TechWorldwithNana]

Wow that's great! Please share the video, would be very helpful for me :)

[@pratibhagupta8916]

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 :)

[@mostinho7]

Done thanks Notes copied to OneNote 3:00 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.

[@PouyaAtaei]

Thank you Nana, you probably have some of the best quality videos on Kubernetes

[@Dragoncheg]

Thank you! Very clear and straightforward, which, with a tool as complex as Kubernetes, makes it very easy to understand.

[@Khalid15325]

Your channel is a pure gem, YOU’RE a gem too Nana. Thank you so much for all your work. Best wishes.

[@zeynepdonmez8495]

This video is even better than the training I bought online. It makes everything clear and summarizes all the key information. Thank you!

[@IshanPalimkar]

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 ~!

[@abhi_galav]

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

[@rockmanexe1994]

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.

[@surya9871]

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

[@pranjalikamblekar7712]

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 :)

[@pranavgore5860]

Very clear and to the point. You are my go to channel if I want to quickly understand something in Devops

[@KohliTendulkar]

Wow, Awesome is an understatement. THANK YOU for the clear explanation.

[@mediatwinkleTV]

From a Certified CKAD, CKA expert, this is by far the best explanation of the kubernetes architecture !

[@anilkommalapati6248]

[@esaruhan]

Thanks, specially for supporting explanation with visual representation.

[@anumukondavenkatarangateja4744]

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

[@sanjeevkumarnarayanaswamy761]

One of the best videos, I love to watch. Keep continuing. Thanks

[@Write_Linux]

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.

your content are pretty clear to understand the concepts of K8s. Suggestion: It will be great if you have any discussion forums like slack channel or something.

[@TechWorldwithNana]

Thanks for the suggestion. I'm thinking about doing it :)

[@priteshoe]

Haven't come across such clear explanations of processes running on master worker node and K8s architecture before .. Brilliant work .. Can u also cover managed K8s services like EKS ECS and fargate if possible Thank you ..

[@TechWorldwithNana]

Thank you so much for such positive feedback 🙏 Sure will consider to cover them! thanks for the suggestion.
