In this video you will learn about Service Mesh and one of its implementation, which is Istio.
In order to understand the concepts, we will first look at the new challenges introduced by a Microservice Architecture.
Then we will see how different features of a Service Mesh solve these challenges.
We will look at how Istio implements Service Mesh and learn about Istio architecture as well as how to configure Istio for our microservice application.

[@ayushpratap4726]

Nana, please make videos for Vagrant Technology Also if you get time!

[@glassdoor6177]

Thanks.. excellent video! Quick q - if a service needs to return response back to request then do all responses go via envoy proxy as well ? Or envoy only comes when request is routed to service and if service wants to communicate to other service?

[@adamroberts4283]

Nana is by far the best educator on youtube when it comes to dev ops. Honestly no one even comes close to the detailed approach she takes for each video.

[@TechWorldwithNana]

Thanks so much Adam, really happy about such positive feedback! :)

[@Pengoled]

I totally agree.

[@1ineed]

Can't agree more. 👍👍

[@JohnLastName]

As someone who is trying to come up to speed on some of these "newish" dev ops tools, I couldn't agree more. Different people learn via different ways, and IMO Nana knows how to deliver the content based on a "what is the problem/challenge"..and this is how it is solved. While at the same time explaining the technical solution in an easily digestible format. Well done all around!!!

[@sealuke2724]

[@HavMath]

Haven't seen any tutorials which explained this simpler

[@prajan6806]

The Best Istio Recap Ever!!!!

[@muneermansoori6196]

I had no expectations from youtube, anyone can give. This kind of content, you have explained in so good way :) I have liked, commented as well as subscribed to your channel... thank you so muchhhhhh!!

[@devinwong2506]

While others keep abstracting a concept with many even more abstracted terms and nested documents, you are doing such a great job that you try to explain in examples and then bring up the concepts in a clear way. Really thanks for your videos and diagrams in your videos. It saved me a lot of time to deal with the new terms and architecture.

[@deepakbhoria4172]

No one comes close to your style of education. Calm and deep introduction !!!

[@arindamsengupta9465]

All corporate professors who take pride in explaining things as if they are complex will now find place to hide their face. 🙂 proud of you Nana 🙏🏻

wow that was brilliant, best video to refresh and for interviews

[@eyeofbass]

Nicely done. I’ve been through countless service mesh overviews but this one was just right and complete. Thank you.

[@saravanachilla]

Nana, you are THE BEST educator. Please don't give up this profession as you are adding a lot of value to the people.

[@RakeshKumar-nj3ts]

Service mess explained precisely and excellent way. It goes directly in mind.

[@Adks007]

service mess has a whole different meaning. Just kidding. Typos are funny

[@jean-baptistelasselle4562]

Really fun though , ill Creuse the service mess lol

[@nikhilnavare]

Ha ha ... the typo

[@SanjayRoy-vz5ih]

Its really get messy if you don't use the mesh...but it's such awesome tool

Hi Nana, Thank you so much for this video. One of the greatest video, I have watched in the recent time. It cover the fundamentals + all of the advanced core concepts. I became a fan of all your videos :). God bless you ! Looking forward for more videos like this one :)

[@vctrmagno]

YT recommended -> I took the chance -> I watched an awesome talk -> Subscribed!

[@TechWorldwithNana]

Happy to hear Victor! 😊 Welcome to the channel!

[@kasjo2319]

Yeah, same here :)

[@subhabratabanerjee3087]

exactly same happened to me also :)

[@killerlookshunk]

Sane here !

[@tebogomahlomoja4368]

The content is well presented, precise and to point. Gives a solid foundation into service mesh as well as microservices architecture. Well done this is gold standard.

[@ManishKumar-ud5so]

You don't need Siri, you need Nana. Thank you! You have no idea how much I learn from you every week. I would take one of your paid class to thank you in some tangible way. Keep spreading the wealth of knowledge.

[@TechWorldwithNana]

Thank you Manish 😀 Really appreciate your positive comment.

[@mraarone]

It’s always great to proxy these videos to coworkers. Thanks for letting me ride sidecar!

[@rvmu]

I've seen quite a few tutorials on KZbin over the years. You are clearly the best one. Congratulations!

[@somenathchakrabarty2473]

Excellent video ! within 5 minutes I could get the essence of Service Mesh

[@sumitagrawal79]

Blown away with the way you develop tutorials....Its simply amazing...Kudos and keep doing the good work for the community...

[@MyGhostnote]

An amazing simple explanation of istio. It would be great if you could have a video similar to the docker course explaining it in real time. But the content is direct to the point.

[@ningw7730]

Istio is really complicated. I had a very hard time understanding it myself. This is a NICE video to visualize istio components directly. Hope to see deeper Istio related concepts in the future ( egress, envoy, cert-manager)

[@AmorDz]

Absolutely stunning, awesome slides, simple language, nice idea's order. You are amazing! Subscribed :)

[@sln0782]

I just found your channel, your content and explanation is amazing, thank you!!!

[@premk]

When I want to learn abt a topic quickly and to the point I watch Nanas videos . Never been disappointed . Just what I need to know . No fluff

[@Bbluenight]

You have great training skills, you make it look simple so people understands the concept. I think that's the biggest and more important step before going into a new tool/app/technology. If people get lost in documentation about a new tool, they will get frustrated and fear it. Thank you so much for your contribution, I learned at my beginnings from your videos and they helped me a lot. I always recommend you to people that want to understand what's under the hood. Keep up the good work !

[@vinny1577]

Really appreciated all the content here. Came in to learn about Service Mesh, Istio, Envoy, Sidecar etc, and I must say I was able to get a very good high level idea about them.

[@vinshankar]

One of the best and crispiest videos on Istio introduction. Thanks for posting the same.

[@yanjim]

This channel is extremely helpful. Keep it up, Nana!

[@padmask8692]

Wow, such a fantastic, clear and crisp explanation. Thank you

[@sturdyone111]

Nana, I love you! Every single video you've produced is a masterpiece! Thank you so much for spreading the knowledge!

[@santiagofranco9715]

Thank you for this awesome video. I was jumping from forum to forum trying to understand this in the most simple way... you just did. Again, you are awesome, thank you very much for teaching this way!

[@vedranmaricevic6760]

Now I understand it. This explanation really got me!!!.... Thank you.

This is great Nana! Would you consider doing a video about protocol buffers (or gRPC specifically)? I’d also love a video about event-driven systems like Kafka

[@PremKumar-bp7ej]

World best educator your. I learn daily with a lot of course added by you. Keep continue your education service. Many thanks nana...

[@Harishicu]

Very clear explanation, I had zero knowledge on this topic and after watching the video I can now understand the fundamentals of Istio. Thank you so much for such a great explanation!

[@DannyNatale]

Woah, this was an outstanding video and really made things clear for me. Thank you, Nana!

[@travelwithdb]

Outstanding explanations. I didn't know anything about Istio and within 5 mins got a full understanding. Thank you so much.. :)

[@brianfleming8310]

"The network layer for service to service communication that consists of the control plane and proxies is the service mesh". Developers like to use fancy words like "mesh" to impress and confuse you, but when someone can just break it down into a sentence like this, they got my 👍. Thank you!

[@fakecubed]

They use those words because saying a lot of words when you can just say one is useful when you have to say it a lot of times to other developers.

[@markdudley2189]

Clear explanation I have seen so far! Thank you very much for doing this!!!

[@djpune]

BEST video on SERVICE MESH !!!

[@sachajw]

Nana you rock! Pure genius! Thank you for demystifying the tech in a microservices world!

Love your tutorials Nana! Could you make a tutorial for how to build and deploy docker images to gitlab repositories? I've been trying for some time now, but i didn't even manage to make jenkins to run docker commands at all, and I'm sure that if you were to make a tutorial for this i'd be able to do it with no sweat, beacause your explanation are always so clear, and that's why i really love your tutorials and always come back to them to revise something that i might have forgotten
