What are virtual machines and containers, and how do they fit into our modern cloud-native way of building and architecting applications?
In this lightboard video, Nigel Brown with IBM Cloud, answers this question and much more in four parts. He also breaks down why users should not just look at virtual machines and containers as competing technologies because there can be a lot of benefits of having them work together for particular use cases.

#Containers #VirtualMachines #CloudComputing - Наука та технологія
key sentence is: "VM is isolation of machines, while Containers is isolation of processes"
thats actually pretty deep😂😂
Yeah, well that was the world in 2016. Since than some things have changed in regards of containers - and (traditional) process level isolation is today starting to feel somewhat legacy ;) At least from the security perspective.
@@ThoriumHeavyIndustries do you mean for example we need VPCs to increase security between container processes? Would love to hear your thoughts about this as I'm not very familiar =]
@@ThoriumHeavyIndustries Hi Thorium, can you please share something on what you said?
@@7heLostAndDamned There are several projects going on for some time to add a lightweight virtualization layer to container runtimes. The most important project in that direction is KATA, but there are some others. This year we have already seen 3 critical vulnerabilities affecting especially container platforms, so this is surely they way to go if you dont want to intensively dive into SELinux and Seccomp. Baidu did an awseome whitepaper on their use of Kata back in oct.2019. RedHat also has this on their Roadmap for OpenShift probably coming this year.
1. The level at which virtualization happens - virtualization happens at hardware level vs. OS level
2. The type of isolation achieved - isolation of machines vs. isolation of processes
3. How resources are accessed - via hypervisor vs. via kernel features such as namespace and cgroups
4. Flexibility of hardware vs. portability
Great note taking skills! Bravo & thanks!
That pretty much summarizes the video. Thank you
summarizes the video, but if you would explain it like that in short sentences to someone who never used VMs or containers they would be dumbfounded. like the video and how it introduces you to the main points.
@@PsychoPod the video was pretty simple dude just playy it back it back like i did lol
@@OWUchii I was commenting on the comment, not on the video. Video did a good job explaining everything.
Can we get Nigel to do more explanation videos? Super great explanation and very personable speaker!
His my fav.
Couldn't agree more.
Agreed thats the best explanation ive ever heard.
Finally someone who can make the topic understandable. Nigel, you and the team that produced this video are great. IBM is really lucky to find you!
Dude, I wish I had more teachers like you when I was entering the tech field. You have explained this very well in such a short video.
2:17 OS level virtualization --Containers vs hardware level virtualization --VM
4:17 isolation of process --Containers vs isolation of the machine --VM
4:22 different in access:
5:37 different in flexibility(VM) and portability (Container) : [6:03 Docker file]
6:55 Type1 HYPERVISOR & Type2 HYPERVISOR;
7:22 collaboration of type2 HV (flexibility) and Containers(portability) --KubeVirt, new version of Kubernetes, OpenShift.
Very well explained Nigel, really liked the way and the speed at which you explained - not too fast or too slow. Keep it up, make more videos. Cheers!
I'm really impressed with the explanation as well as the lightboard which has been used. Most tutors use traditional whiteboards or PowerPoint presentations. Technically and content wise this lecture is a class above. Thanks a lot Nigel!!!
I mean its IBM
By far, this video brought more clarity about containers than the many videosI watched previously. Newbie to cloud engineering and getting my knowledge up for the AZ900 so trying to dissect everything cloud. Thanks for making this much easier to understand and build on!
Finally I found a clear and clean explanation about these two confusing (at least for me) concepts.
Thank you for excellent presentation!
The easiest and best explanation that I have seen on youtube about containers vs VM! Nicely done!
Great video and explanation. I have went through training but this is one of the best explanations that I have had. Thanks for sharing.
This is best simplest explanation I have seen. Thank you NIgel. I'll look for other videos by you.
Great video. You did an awesome job explaining the strength of both VMs and containers.👍🏽
💡AHA! Moment here @7:21! We can run VMs and Containers as technologies that can work together not as competing technologies. Great video! Shoutouts to the whole team behind this video! Nigel, you're amazing!
Real sweet-spot delivery: technical content explained clearly and accurately, in accessible and conversational language. My employer holds twice-yearly conventions; I'd give a lot to have Nigel Brown invited as a guest presenter.
Thanks. I’ve been trying to understand containers for an AWS cert exam and other videos were either too detailed or full of vague company jargon that the average person doesn’t understand. This is short, clear, and to the point. Thanks!
Nigel's energy is infectious! Please more videos with him😊
Thank you Nigel for an amazing presentation. The information you presented was so clear and concise despite the gravity of the content. If I can't explain Containers vs VMs to my grandparents, then I don't understand the technology myself. Thank you for allowing me to express my new found knowledge with others.
Awesome job explaining these topics! Please have Nigel in more videos!!!
this bro is just amazing. I took notes of every word he said and understood every bit of it. Thank you bro.
Thanks Nigel. I am just prepping for my AWS Solutions Architects exam and this explanation was clear, concise and delivered in an enjoyable and engaging style.
Finally, someone who knows how to demystify vague IT concepts; thanks brother for an absolutely lucid explanation.
Clear, concise, digestible lesson. Very impressed
Man, that was one of the greatest explanations I've ever seen! Congratulations Nigel and IBM!
Thank you, Leonardo! 🙏 Glad you found it useful!
Great explanation! And thank you for the education and representation 🙏🏾✊🏾
That was actually very well explained. So clear.
Damn this was thoroughly explained and simplified
Excellent concise explanation, thanks Nigel!
Great explanation. Love the part about "...isolation of process." Makes Docker crystal clear.
Dudes enthusiasm makes it easy to understand. Loved it! Love me some containers!
Dude you know your stuff so easy to listen to--you are probably great to alongside with!!!
Nigel!!!! This is exactly how I remember you in Production School! lol. Great Teacher, Great Mind, Great Person! Tell mom I said Hi!
This guy is great! I really feel like I learned something here, keep it up Nigel!
Hope to see more from this guy, succinctly explained so even novices can understand!
Vraj Patel I completely agree. I’m a pretty not smart person and Mr. Brown here made me feel like I could do anything.
I almost thought you were gonna say the n word O_o
Couldn't agree more! He explains things in way that makes you want to learn more! Thank You so much Mr. Brown.
@@Beerferatu i also agree with you. He is very natural and brings no over-hype voice to his presentation. Just easy to listen to.
Great explanation Nigel, the concepts stuck in my head.
Nice presentation. You made it so easy to understand. Agree on comments below that the key take away: "VM is isolation of machines, while Containers is isolation of processes". Much appreciate your effort.
Such a great explaination. By illustrating how VMs vs Containers are built, you clarifed alot. Thank you good sir!
Great video. I’ve been passively wondering what’s the difference for months. U gave me the answer spot on
Thanks for watching, Emil! 😃
The best video in the internet explaining this concept. Period
Beautifully and effectively presented!
This is super tastefully edited. Compliments to the editor/graphic designers (:
Nigel, you explained PERFECT! Loved this presentation!
This is my third video on containers, and I finally get it. Excellent explanation!
Simple and easy to understand. Well done. Thank you
Great video. I like the fact that at the end, when the thumbnails for other UA-cam videos show up, the main video is turned off and the main screen goes black, but the main video's audio is still audible.
I recently started to learn some very basic stuff with Linux about a month ago and my friend was showing me things about containers and docker files (we were using discord). This video was a tremendous help to me now, a month later, in making all that information he was showing me click. Now it makes so much more sense with your simple visual breakdown between VM and Containers. Amazing job!
Thank you!
Very well explained. Thanks Nigel. Looking forward for more of your videos.
Thank you! That’s the exact difference I needed to hear. VM is at the OS level and containers are at the process level.
Finally I understand after hours and hours of reading information. Thanks Nigel!
Great job Nigel..!! Glad you did this post...
Crystal clear presentation of conceptual application approach anchoring the basis of difference between elements and beyond environment.
This was a WONDERFUL explanation! Thank you!
I made an assumption about Type-2 VMs in that Hyper-V, on Windows 10 or Server, was considered Type-2. But according to Microsoft it is actually Type-1. Until I saw this video I was not aware of the Type-1 / Type-2 distinction, even though I was aware that there was or should be one. I enjoyed your video Nigel. Thank you.
This was such an amazing explanation Nigel, hats off🙌
Excellent overview -- agree with Rick Chow on the isolation difference - thanks
Well this is the most clear I've been on the difference, but I'm still gonna need like another 5 hours of these discussions before it actually clicks for me from the type 2 perspective.
Great Explanation - you made it so easy for me to understand containers as compare to VM .
I am a AA female and I loved seeing you on this video tonight! Gave me so much inspiration thanks!!
thank you for differentiating between vm and container in a clear manner
Awesome video. Awesome speaker. Clear and concise and easy to follow
Wow! What an awesome video! Thanks, Nigel!
Smooth explained and in a simple way
Always wondered the differences. Thanks for the info.
This is the best explanation of this I've ever seen
This is a great explanation! I’ve been seeing more and more docker and kubernetes and just couldn’t figure out why somebody would want a container if they both technically make Virtualization. But seeing that one happens at the hardware lvl and one happens at the OS level that makes a lot of sense. I wonder if there is a security risk between the containers if somebody is able to gain access to the OS.
EXCELLENT explanation and presentation!
Very well structured, Nigel
I so loved this. Im working with VMs and interested in moving to containers so this helps a lot
Glad you found it useful! Thanks for watching! ✌️
Be sure to check back on our channel from time to time (or even subscribe). We've got more interesting videos coming up.
Very well explained, thank you!
Very good presentation. I am a type I virtualization guy. I have been looking to get into containers to build my skills. Solid down to earth explanation.
Thanks for watching, Dewayne! 💙
very well explained. thank you very much
Respect to Nigel! Very cool explanation!
Great explanation, made a lot of sense, very helpful.
Perfect, hats off to Nigel
Wow! It was explained in a very simple way. I think I can show it to my grandma and she will get this
Its so to the point meaning in so simple way , salute to the kind of ur investment to explain so deep in clear crystal policy, where as in internet even videos are unable to a clear picture on it.
Can we get a video explaining how the presenter was able to write in reverse writing so well?
It's something called light board (ua-cam.com/video/wCOuu0-o5YI/v-deo.html).
The footage you're seeing is already flipped.
Hint: mirror image.
That's correct! 👍 Here is a blog post we wrote that explains how we do it. ➞ ibm.co/3eItmz7
they probably flipped/mirrored the video
hint: he's not left-handed
Awesome explanation. Thank you, Nigel! One thing is I just couldn't ignore the sharp scratching noise caused by the marking pen which can really drive my brain crazy.
I'm 100% with that, the scratching noise is really troubling- wonder why it was not there in some other videos.
Bloody hell man, that was brilliant. This type of video really puts IBM on the map for me. Very informative in a very easy to understand format. This was a precursor for me to understanding Kubernetes for a work project. That's a totally different beast. But for now, I learnt what was essential. Many thanks.
You're welcome, Steve, and thanks for the great feedback! 🙏 Be sure to subscribe for more videos like this one. 😉
Nice video and explanation was nice , anyone new to these terms also understands this.
Finally someone managed to explain this in a way that even I could grasp.
This helped a lot thank you Nigel.
Great discussions of Virtual machines vs containers.
very clear explanation, thanks for the nice work
Thanks for the explanation Nigel!
Best explanation I found ! Thanks
It's 2AM and i'm watching tech videos for no reason, they just make me feel good idk why
🙌🔥
Clear and concise explanation
Dude, I want to hug you - that was a great explanation.
Subscribed.
Nigel, it would appear, has found a really good niche and format IBM.
Chase after it!
Great job explaining this in human. Thanks Nigel.
Thank you Sir, clear and straight forward explanation...
Way to go, simply perfect!!
That is honestly very helpful. Thank you so much!
Folks and IBM Cloud, any other videos by Nigel? I've been searching.... This was brilliant!
Thank you , this helped me understand difference between VMs and Containers
We're so happy to hear this! 🙏 Be sure to also check out the links in the video's description for more resources. ⤴️
This guy is awesome!!! So well explained...Thank you.
,
such a good video with great explanation. Thanks!
Most understandable explanation. Thanks so much!
Very clear explanation! Thanks 👍
