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.

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.
So Nigel is left handed and writing backwards? Impressive
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.
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.
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.
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
💡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.
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!
Finally I found a clear and clean explanation about these two confusing (at least for me) concepts.
Thank you for excellent presentation!
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!
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.
Finally, someone who knows how to demystify vague IT concepts; thanks brother for an absolutely lucid explanation.
Nigel's energy is infectious! Please more videos with him😊
Damn this was thoroughly explained and simplified
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!
This is best simplest explanation I have seen. Thank you NIgel. I'll look for other videos by you.
The easiest and best explanation that I have seen on youtube about containers vs VM! Nicely done!
Great video. You did an awesome job explaining the strength of both VMs and containers.👍🏽
Great video and explanation. I have went through training but this is one of the best explanations that I have had. Thanks for sharing.
It's 2AM and i'm watching tech videos for no reason, they just make me feel good idk why
🙌🔥
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!!!
Man, that was one of the greatest explanations I've ever seen! Congratulations Nigel and IBM!
Thank you, Leonardo! 🙏 Glad you found it useful!
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.
The best video in the internet explaining this concept. Period
Great video. I’ve been passively wondering what’s the difference for months. U gave me the answer spot on
Thanks for watching, Emil! 😃
This is super tastefully edited. Compliments to the editor/graphic designers (:
I am a AA female and I loved seeing you on this video tonight! Gave me so much inspiration thanks!!
That was actually very well explained. So clear.
Great explanation! And thank you for the education and representation 🙏🏾✊🏾
Clear, concise, digestible lesson. Very impressed
Nigel!!!! This is exactly how I remember you in Production School! lol. Great Teacher, Great Mind, Great Person! Tell mom I said Hi!
this bro is just amazing. I took notes of every word he said and understood every bit of it. Thank you bro.
Great explanation. Love the part about "...isolation of process." Makes Docker crystal clear.
Great video. I like the fact that at the end, when the thumbnails for other RUclips videos show up, the main video is turned off and the main screen goes black, but the main video's audio is still audible.
This is my third video on containers, and I finally get it. Excellent explanation!
Excellent concise explanation, thanks Nigel!
Dudes enthusiasm makes it easy to understand. Loved it! Love me some containers!
Finally I understand after hours and hours of reading information. Thanks Nigel!
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!
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.
Nigel, you explained PERFECT! Loved this presentation!
Great explanation Nigel, the concepts stuck in my head.
Thank you! That’s the exact difference I needed to hear. VM is at the OS level and containers are at the process level.
Dude, I want to hug you - that was a great explanation.
Beautifully and effectively presented!
Nigel's killing it. Sure-footed and warm.
Wow! What an awesome video! Thanks, Nigel!
Dude you know your stuff so easy to listen to--you are probably great to alongside with!!!
Simple and easy to understand. Well done. Thank you
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.
Such a great explaination. By illustrating how VMs vs Containers are built, you clarifed alot. Thank you good sir!
Excellent overview -- agree with Rick Chow on the isolation difference - thanks
Very well structured, Nigel
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 job Nigel..!! Glad you did this post...
This was a WONDERFUL explanation! Thank you!
This is the best explanation of this I've ever seen
Always wondered the differences. Thanks for the info.
Perfect, hats off to Nigel
Folks and IBM Cloud, any other videos by Nigel? I've been searching.... This was brilliant!
Finally someone managed to explain this in a way that even I could grasp.
Very well explained. Thanks Nigel. Looking forward for more of your 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. 😉
Can we get a video explaining how the presenter was able to write in reverse writing so well?
It's something called light board (ruclips.net/video/wCOuu0-o5YI/видео.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
Thanks, Nigel. Excellent work.
EXCELLENT explanation and presentation!
Very well explained, 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.
"Whats up ya'll"..... I immediately like this guy
Respect to Nigel! Very cool explanation!
Crystal clear presentation of conceptual application approach anchoring the basis of difference between elements and beyond environment.
Best explanation I found ! Thanks
Great job explaining this in human. Thanks Nigel.
wow I wish I had a teacher like you in my bachelors.
Wow! It was explained in a very simple way. I think I can show it to my grandma and she will get this
Great Explanation - you made it so easy for me to understand containers as compare to VM .
Great discussions of Virtual machines vs containers.
Awesome video. Awesome speaker. Clear and concise and easy to follow
Way to go, simply perfect!!
thank you for differentiating between vm and container in a clear manner
Smooth explained and in a simple way
Wow great and precise explanation
This helped a lot thank you Nigel.
Very clear explanation! Thanks 👍
Great explanation, made a lot of sense, very helpful.
Very good explanation! It helped me a lot. Thanks!
This was such an amazing explanation Nigel, hats off🙌
such a good video with great explanation. Thanks!
Nigel killed this. Get this guy in more videos!
This was the first explanation of containers that I actually understood!
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! 💙
Nice job Nigel, making us IBMers proud!
One comment -- none of this is specific to Linux, all of it can run on Windows, System z, etc, etc.
Excellent Explanation Nigel!!
what a great overview.
Great breakdown on isolation.
very well explained. thank you very much
