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.
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
Thank you for always objectively expressing the pros and cons of various design approaches. As someone once said, all architectural decisions are trade-offs.
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.
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.
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!!
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
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.
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.
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
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 :)
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
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.
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.
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?
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.
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.
Great explanation and specially simplicity of the content makes it really easy to understand. Which software do you use for these prestation and animation?
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.
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!
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).
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
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
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. :)
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
Thanks for the video - great illustrations. Is it really true that containers are easier to manage? I can see that it is possible to run more containers than VMs per physical machine, but a lot of applications don't require their own. You are showing MySQL running as a container. What is the advantage of doing that? My experience is that containers are best suited for applications that are stateless as the container loses state when it restarts, MySQL does not fall into that category. I often see DevOps falling into the trap of using a pre-configured container without any understanding of its configuration fit. Do you agree? I believe that containers are best suited for stateless applications (CPU intensive) that can easily be started, shutdown, scaled, and moved. Do you agree?
My take away from this video is that system designs is about trade off. Every enterprise will have to consider what to trade off base on legal requirements and compliance, operation going concern and board approved budget.
The way you choice which type you use is in the following order: - Is your daddy rich ? - You go with Bare Metal. - Have your earned your own cash ? - You go with Dedicated server machine. - Have saved a bit of cash? - You go with containers/virtual machine. - Are extremely poor? - Choose shared hosting. :D

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

Thank you for your succinct explanation of the differences between these computer architectures.
Smooth animations, direct language, and delivers 100% on its promise. Great content!
Best ever explanation of VM v/s Container
Lucid explanation with vivid illustrations.
Great Sir
The best classes for system design
Explanation is simple and sweet, hats off.
what a simple and informative explanation, thank you, Sir.

I love this channel!
These are two superb professionals with excellent content!
Thank you for your work and content!
Definitely one of the best channels on TH-cam. Great content

this is quickly becoming one of my fave TH-cam channels. Your videos are amazing man, hats off
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!
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!!
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.

Thank you! Each one of your video is so high quality! Subscribed to see more to come!
Very clear. Excellent summary thank you!
Excellent! just what I was looking for. Would love to see and hear your detailed explanation of serverless and edge computing.
good one to refresh the memory. clean and neat explanation
Amazing content, very concise and clear. Keep posting more videos.
Clear and concise explanation. Btw how you are making videos like this. Curious to know..
Thanks for the subtitles!
FINALLY! I finally found your YT. Good job on the fantastic LinkedIn and email content.
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.
Greate video. Thanks. The explanation of Container is really great.
Great job! Thanks for sharing.
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.
Excellent explanation, thanks for your efforts!
thanks for theses videos you recorded, it help me a lot
I learn it from beginning
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?
please guys keep going. it is very informative
Your animations make me all tingly in my tender parts
6:20

good stuff and eloquent explanation keep up the good work...( genuine request please make a playlist on your channel for easy access)
A channel worth to share! No hyped up claptrap, just good explanations straight to the point. Thanks!
Very good breakdown. Thank you.

Clear and concise!
is it possible to have a video to tell the differences between SDS, HCI, Openstack, K8S?
Please do a video on serverless too
Another excellent video by ByteByte !
thnks alotttttt for uploading this great video.. please upload more related video. like Data centre n Servers n cloud
Thanks for sharing. Question - why VMs are more vulnerable to "noisy neighbors" than containers? Aren't VMs more isolated comparing to Containers?
Good Information, crisp presentation.Thanks.
This was excellent. Subscribed for more. Thank you.
Fantastic video 😀! Thank you !
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
Amazing video. Thanks brother
Awesome explanation !!!
Lovely insight in short..
bravo! I like your videos! Thank you master !
Amazing content 👌🏻 can't wait for your next videos 😍
What are the design considerations for container engine vs hypervisors?
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?
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
"Once upon a time, all servers were bare metal." That sounds so metal. :) Great video (again)!
Except when one gets to mainframes. Where the VM idea originated.
Great information thank you for sharing
good information. can you do LPAR next. where does it sit? is it under bare metal, virtual or container
thanks for short clear answer
A video is about misconception, but the there is a misconception that bare metal is expensive. Bare Metal is actually the cheapest
Really nice and useful information 👍 please continue 👍
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. :)
Thank you for the new info
What a great content ❤️❤️❤️
Amazing explanation!
He knows everything
What's the Misconceptions about VM, microVM(kata, firecracker, gVisor), runc(docker, containerd), wasm?
Really Great Explanation
i was confused with bare metal server and bare metal hypervisor.....thanks
Vmware esxi is bare metal hypervisor, ms hyper-v is os-based
Does anyone know how to create such videos? Which software or platform is used to create such amazing videos?
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
Please make content on AWS, GCP & Azure, Thanks.
Superb explanation ❤️
How do you monitor for symptoms of the noisy neighbour problem? Any recommendations for (a) On-prem kubernetes (b) Cloud multi-tenant ?
Loved this!
Docker containers are sandboxed, so it’s not easy to bypass that sandbox
Thanks for the video - great illustrations.
Is it really true that containers are easier to manage?
I can see that it is possible to run more containers than VMs per physical machine, but a lot of applications don't require their own.
You are showing MySQL running as a container. What is the advantage of doing that? My experience is that containers are best suited for applications that are stateless as the container loses state when it restarts, MySQL does not fall into that category.
I often see DevOps falling into the trap of using a pre-configured container without any understanding of its configuration fit. Do you agree?
I believe that containers are best suited for stateless applications (CPU intensive) that can easily be started, shutdown, scaled, and moved. Do you agree?
What do you use for your diagrams, if you don't mind sharing? They look so nice 🙂
Excellent video
Containers are a pain to work with from my experience.
My take away from this video is that system designs is about trade off. Every enterprise will have to consider what to trade off base on legal requirements and compliance, operation going concern and board approved budget.
The way you choice which type you use is in the following order:
- Is your daddy rich ? - You go with Bare Metal.
- Have your earned your own cash ? - You go with Dedicated server machine.
- Have saved a bit of cash? - You go with containers/virtual machine.
- Are extremely poor? - Choose shared hosting.
