There is an error in your video. "Bare metal" hypervisors do *not* require expensive hardware. Microsoft Hyper-V requires a CPU with the features "x86-64", "NX bit" and "VT-x", which has been standard cheap consumer grade hardware for a decade.

[@gerardorojas3856]

This channel is PURE GOLD OMG!! The time, the love, the dedications spent in these videos, soft animations and simplifying everything is awesome, thanks for sharing your time❤Están espectaculares todos los videos!! :D

[@ketaminefairy]

As a total newbie I find this videos very easily digestible, and perfect to watch on 1.75x. This is some great work, thanks!

[@viky293]

Great quick overview about all three. Isolation, control & maximum hardware utilization are the true objectives of doing all this stuff.

[@bernardomenescalferreirada5404]

Smooth animations, direct language, and delivers 100% on its promise. Great content!

[@deadohiosky1701]

Thank you for always objectively expressing the pros and cons of various design approaches. As someone once said, all architectural decisions are trade-offs.

[@r_mclovin]

I've only watched like 3 videos but this is already one of my favorite channels! Thank you 100000x for providing this valuable knowledge with such great visualizations for free!!

[@saeethegreat1672]

Your videos are amazing! Your explanations are so easy to understand and fluent and the animations and the visual effects make them so much more interesting to watch. Overall thank you for these absolute gems and I hope to see your channel grow a lot.

[@mario_luis_dev]

this is quickly becoming one of my fave KZbin channels. Your videos are amazing man, hats off

[@robbmanes]

I use your videos to send to my peers who need good explanations for things; you say all of the important things while leaving out all of the fluff which makes them more watchable.

[@Vinod_Kumar827]

It was a refresher for me and thanks for explaining it very well. You spoke about edge computing in the end. And there is also a concept of Quantum computing. I wish if you can create similar videos to explain about both Edge computing and Quantum computing, I would really appreciate that :)

[@evdokiya1377]

I love this channel! These are two superb professionals with excellent content! Thank you for your work and content!

[@kittipongpiyawanno315]

Very good and clear explanation. To be pedant, about "Bare metal is expensive hard to manage and hard to scale", it depends on many factors. In the most cases, it is undeniable true. But in some case e.g. you run app server on many machines and want to squeeze every single drop of your H/W, bare metal could be the cheapest. In some aspect, it is also possibly the easiest, since you cut the administration of between-layer like hypervisor or container management. In some aspect, not, like migration of app server to other machine.

[@solomonxie5157]

Thank you! Each one of your video is so high quality! Subscribed to see more to come!

[@kuhndj67]

Good summary... while production compliant machines supporting popular bare metal hypervisors are pretty expensive, I've found that I've been able to install ESXi (my environment of choice) on a number of 'noncompliant' machines for test/eval... then go the expensive stuff for production (so folks interested in learning shouldn't be afraid to grab the free version of esxi and try installing it on one of their older machines) . Noisy neighbor can usually be managed with setup... without losing the ability to increase capital utilization by leveraging those machines for other tasks during less busy periods... and of course the ability of a production virtualization or containerization environment to optimize hardware utilization by moving workloads around (on the fly) REALLY kicks things up a notch.

[@plusultra243]

Amazing content, very concise and clear. Keep posting more videos.

[@bobdinitto]

Thank you for your succinct explanation of the differences between these computer architectures.

[@rva548]

Definitely one of the best channels on KZbin. Great content

[@abhishekgowlikar]

Explanation is simple and sweet, hats off.

[@ChrisM541]

Excellent video, thanks for the upload. Coming from using computers in the 80's onwards, I immediately though "Bare Metal" = assembly language programming :) But yes, I can see that when talking about servers (or anything) we can, today, have different levels of abstraction. It's nice/calming to know (and expected) that Bare Metal here still = fastest...for exactly the same reasons - the more pathing you place between action initialisation and 'end-point' execution (i.e. machine code) then the slower the performance. Since machine code is the only language every CPU understands then, ultimately, that's what's running for every app/process.

[@tamilchelvanramasamy8733]

Lucid explanation with vivid illustrations. Great Sir

[@joross8]

Awesome video. As always, you do a great job of presenting the basics in a way that is accessible for newcomers while still being a useful reference for existing engineers.

[@darthboren]

best explanation of this space that I've seen. Well done.

[@JCArtuso]

Great job! Thanks for sharing.

[@jorper98]

Great simple explanation and format - well done.

[@z911empire]

Very clear. Excellent summary thank you!

[@QuantumImperfections]

FINALLY! I finally found your YT. Good job on the fantastic LinkedIn and email content.

[@skgyan]

Great explanation and specially simplicity of the content makes it really easy to understand. Which software do you use for these prestation and animation?

[@husseineldeeb]

Excellent explanation, thanks for your efforts!

[@Trintrin20]

Fantastic video 😀! Thank you !

[@mikemorris5944]

Excellent! just what I was looking for. Would love to see and hear your detailed explanation of serverless and edge computing.

[@mailbrn78]

Neatly crafted step by step. Quite easy to remember, Thanks for this video. As you said in the video about regulatory, can you please make a video in line with regulatory requirements to be followed during the design phase.

[@playertwo9895]

Great video, really liking the content on this channel!! @ByteByteGo, when you do the serverless stuff, make sure to include Cloudflare Workers! Cloudflare Workers run on V8 Isolates rather than Containers/VMs because of the speed at which they can be spun up (as well as isolation guarantees). The serverless video would be remiss if this interesting technology was excluded!

[@nemeziz_prime]

Amazing content 👌🏻 can't wait for your next videos 😍

[@MeshaMesho]

what a simple and informative explanation, thank you, Sir.

[@pradnyamane2619]

Good Information, crisp presentation.Thanks.

[@Silent1Majority]

This was excellent. Subscribed for more. Thank you.

[@uptotimeservices]

good stuff and eloquent explanation keep up the good work...( genuine request please make a playlist on your channel for easy access)

[@gwgux]

Good job! Thanks for your hard work on these topics! I'm adding this channel to my list of good resources for people to learn IT. I have several listed on there I'm always looking for more good resources I can send to people. :)

[@dineshtripathi9880]

Greate video. Thanks. The explanation of Container is really great.

[@AnExPor]

Very good breakdown. Thank you.

[@aayushisingh3280]

System design can be understood pretty well if you've got a hang of the trade-offs that are made when choosing one implementation over the other!

[@krumbo]

please guys keep going. it is very informative

[@aaronbcj]

Your videos so helpful. Even though I have your books, videos so much easy to follow and study.. please do videos of all your design problems from books

[@santhoshkumarrajan4963]

good one to refresh the memory. clean and neat explanation

[@libran7664]

thanks for theses videos you recorded, it help me a lot

[@libran7664]

I learn it from beginning

[@NuncNuncNuncNunc]

Clear and concise!

[@servalous]

Even on a Bare Metal a noise neighbour APP can impact the performance of other APP on the system. I see it very often with "MS SQL" and "craftsmen" CRM/ERP Applications. Bare Metal can be compromised easly if you use a MS Active Directory and have every Bare Metal System in it. Still very nicely explained, if you are getting in to this topic =D

[@fuseteam]

A note about 'bare metal' hypervisors, these are actually operating system with the minimum number of services and drivers needed to interact with ths hardware. This is why any linux based operating system can be turned into a 'bare metal' hypervisor; the linux kernel itself is a 'bare metal' hypervisor thanks to it's kvm (kernel virtual machine) module

[@deverasjk]

Thanks for the subtitles!

[@Dragon-ok6ne]

The best classes for system design

[@wassim5622]

amazing content!!! keep it coming

[@lukewayne2371]

bravo! I like your videos! Thank you master !

[@cibi461]

Clear and concise explanation. Btw how you are making videos like this. Curious to know..

[@ML-lg5zw]

Thank you for the new info

[@Faidamine]

Wooow man your viedos are just pricese and full of knwoledge, it would cost me 1h to get same info presented in your 7min video!!

[@shaileshsingh1445]

Awesome explanation !!!

[@rdean150]

Great breakdowns and pro/con summaries. But I'm not sure you addressed the topic posed by the title of the video. What are the "big misconceptions" about these environments? That one is inherently superior to another?

[@vybhaveswaraiah7114]

Really Great Explanation

[@MrZ____]

thanks for short clear answer

[@sharelearn]

Great information thank you for sharing

[@theritesh973]

Superb explanation ❤️

[@Tarun-xw1zf]

What a great content ❤️❤️❤️

[@husseineldeeb]

Amazing explanation!

[@msbanda2123]

Really nice and useful information 👍 please continue 👍

[@viethungha203]

Loved this!

[@shaishavshroff4654]

Lovely insight in short..

[@Freestyle80]

Nice explanations man, hope you cover serverless architectures too like Azure Integration services :)

[@subee128]

Thank you very much

[@NK-iw6rq]

Another excellent video by ByteByte !

[@emmanueljosuecasasmora2797]

Nice and concise

[@vekzdran]

"Once upon a time, all servers were bare metal." That sounds so metal. :) Great video (again)!

[@brodriguez11000]

Except when one gets to mainframes. Where the VM idea originated.

[@jsertx]

Awesome job!

[@ItchyK-bk3jj]

A channel worth to share! No hyped up claptrap, just good explanations straight to the point. Thanks!

[@M911]

Hi Alex Thank you for the content Please, How to develop my self in system design, from where to start, is there a framework or standards or best practices. Thank you

[@dncube]

What tools you use for producing animation and videos? They are really nice with just the right amount of timings After Effects or PPT/Keynote?

[@rbelatamas]

thanks this great video!

[@alexramirez5104]

My favorite new channel :D

[@omni4376]

Nice summery. However hardware virtualization doesn't equal emulation but instead makes use of new instruction sets of modern cpus to enable full hardware isolation between processes that make use of such features. Also notice that container runtimes exist that try to leverage just that to provide better isolation (although uncommon yet).

[@aliyksl123]

Thank you

[@abhisheksitar]

Great video!

[@rogerzhang5993]

Excellent video

[@adeshshetty2830]

What are the design considerations for container engine vs hypervisors?

[@towb0at]

Very nice video!

[@Sawyer0823]

is it possible to have a video to tell the differences between SDS, HCI, Openstack, K8S?

[@muhammedimdaad]

6:20 So container package would be OS specific which depends on host OS while virtual machines aren't. So in that case it is less flexible in terms of OS dependency and comes with own security and host OS limitations.

[@Mrslykid1992]

SMASHING Info!

[@DarthVaderAsip]

good information. can you do LPAR next. where does it sit? is it under bare metal, virtual or container

[@brick4667]

Your animations make me all tingly in my tender parts

[@crodanovic]

Very good channel!

[@modolief]

Thanks !!!!!

[@fatimaiqra2169]

thanks a lot

[@teokahseong]

What do you use to make the animation?

[@DeepenDhulla]

Your video show animated network diagram presentation. Would like to know how we can do same for our presentation and video .At the same time your information video are through the point and easy clear concept explained. Thanks

[@roadracer1584]

Thanks! It's easy these days to get confused by all the technical jargon and gobbly goop. The terms "bare metal," "virtual machine", and "Docker container" are casually tossed about by my colleagues without explanation. No one really asks what's the difference out of fear of appearing stupid or unknowledgeable.

[@victornoagbodji]

What do you use for your diagrams, if you don't mind sharing? They look so nice 🙂

[@SimonZ-vn5to]

Thanks for sharing. Question - why VMs are more vulnerable to "noisy neighbors" than containers? Aren't VMs more isolated comparing to Containers?

[@ReflectionOcean]

Bare metal is physical hardware isolation. Virtual machine is virtual hardware isolation based on hypervisor. Container is virtual OS/process isolation based on container engine and host OS.

[@charlesselrachski34]

Please more! , do containers tutorial videos ( golang bin + kub pod ) [using my laptop to get code/container to send to prod], do kvm vm running fedora where fedora is running distrobox which runs ubuntu server lts running a app at the ubuntu

[@pranaypallavtripathi2460]

Please do a video on serverless too
