He's writing on a panel of glass that has been placed between the camera and the presenter. And then, in post-production, the video is flipped horizontally. (Notice that his shirt pocket is on the wrong side!)
This guy's really deserves respect. In the year when we were not knowing about digital board this guy just made video on light board . Respect gained sir 👏👏👏
IBM ...please find a way to clone this guy. The world needs more excellent instructors like him. Excellent presentation and gives a clear understanding of the material .
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.
I am working 12+ hours a day right now trying to learn as much as I can about web dev, so I'm currently ingesting a lot of tutorial content. With that in mind I can say that you are by FAR the best orator/tutor I've come across in a long time! Max respect :)
This is helpful. So in essence, containers and VMs are similar in that they're both ways to scale computing resources. Containers are more scalable than VMs because they don't need to virtualize the OS every time.
Excellent job! This succeeded in explaining containers to me where all else failed. Thank you very much for your time and research into making this digestible.
A few reasons to use containers rather than VMs: 1. Lighter weight: no need to run an OS in a container comparing to a VM 2. More resource efficient: 1. no extra OS needed to be run in containers; 2. resources in the hosted node can be shared dynamically
I have not seen any business package/host application in VMs as their deployment solutions. Virtualization use case is more of abstracting hardware (bare metal hypervisor). I think the whole idea of Containerization is built around the benefits that you have explained.
A great overview. Seen multiple resources on containerization. Since I don't need to understand it in-depth, this has really helped me and I have to say I really get what it's all about for the first time. Thank you!
Man, you're great! keep it up! I was really suffering with the many useless resources about the same exact thing! but you just did it right! realllllllly thanks!
actually, Solaris 10 added Containers in 2004 .. from BSD jails.. but in a production ready context. ;-) Linux C-groups came much later.. as did so many things, once OpenSolaris published is source code.
What a great presentation! Very engaging and doesn't require amazing feats of concentration to learn the information from you! :-) Good work presenter.
There's an INCORRECT assumption being made in the accounting for resource consumption at @1:45: The presenter is assuming that VM's are hosted on a Type II hypervisor (i.e., A hosted hypervisor). Production workloads are run on Type I hypervisors that don't have an underlying O/S . (e.g., Bare metal hypervisors like Xen, VMware ESX, etc). Therefore Type I hypervisors consume fewer host resources and don't incur the performance penalty of Type II hypervisors.
Barely related to the video, but it occurred to me while I was watching that see-through lightboard videos are probably just flipped horizontally after recording so that the instructor can write forwards.
As long as the apps are designed for scalability in mind then these things can be taken advantage of. There's still a lot of monolithic codebases though.
Thanks great presentation. Can you share what presentation tools you used on this video? It's cool to see a transparent board with you in the background.
I missed the WHY we don't need the "guest OS" in containers. I see you said its better coz it would be light weight without the OS but what compensates for the OS

For a moment, I was super impressed that he could write backwards!

@@epretorious Thanks, I was having a tough time visualizing what was happening here.
notice they all left-handed
Wow this dude is great I need him for my exams
2:54 Agile DevOps
3:25 3 steps to create Container:
1.manifest: Docker file or YAML(Cloud Foundry);
2. image:Docker image or ACI "Application Container Image"(Rocket);
3.container itself:
4:16 Docker Engine
5:45 example: cognitive API + Python application + .js application
This guy's really deserves respect. In the year when we were not knowing about digital board this guy just made video on light board . Respect gained sir 👏👏👏
What a clear and crisp presentation Sai. The way IBM is advocating for Cloud is totally appreciable. count me in...soon.
This video 'Contains' almost everything that will help to get a good overview of Containerization. Great Work!
IBM ...please find a way to clone this guy. The world needs more excellent instructors like him. Excellent presentation and gives a clear understanding of the material .
The comparative example made it much easier to understand the concept of containerization.
One of the best explanation of why containerization is important
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.
I think they flipped the video.
My man is killing it. I'm gonna watch the entire playlist. Thank you in advance!

Hi Adam! Honored to be able to help with your educational journey. Best of luck to you in your future endeavors! -Sai
how did it go working those hours - where are you now compared to where you were 3 years ago? 🙂
@@IBMTechnology how can i sign up to have classes with you ?
@@IBMTechnology how can I register for a class with you guys and get the certification.

before watching this, didn't have any idea about containers. Now its all clear. thanks.
Great high-level overview of containers vs VMs.
Wow one of the more amazing tech presenters out there!
Absolutely, one of the best explainers I've seen so far. His handwriting is gorgeous as well.
nice to read from you
I'm most impressed by the flawless backwards writing
One of the ONE trainers, Sai Vennam. Thank you! Great content in all of your videos.
This is helpful. So in essence, containers and VMs are similar in that they're both ways to scale computing resources.
Containers are more scalable than VMs because they don't need to virtualize the OS every time.
Finally... a clear run-through of containers. good lad
Excellent job! This succeeded in explaining containers to me where all else failed. Thank you very much for your time and research into making this digestible.
Explained the concept in Simple and Crisp way.... Amazing work Sir......
so after months of research, i now understand the docker / K8 architecture. It was a damn long process but this video helped put as well

We're so glad to hear this! And thank you for the appreciation! 👍
I have no idea why the other RUclipsr's forgot to mention the Guest (Host OS) which is everything for this concept, you're Amazing
I just realized that you had to write backwards for this. Awesome.
They filp the video. He is right handed
I really love these videos; great information presented cleanly and concisely.
I liked the way you compare VMs with Containers. It made it very easy to understand the fundamentals with details. Thanks!!
This video really helped me understand containers....thanks Sai Vennam!
Thanks.
You explained such way that I could capture it easily.
Simply straightforward.
He made containers so amazingly simple.
Man, you're great! keep it up!
I was really suffering with the many useless resources about the same exact thing! but you just did it right! realllllllly thanks!
Liked the simple way of explaining the concept and impressed by the graphics!
Glad to hear that! Thank you!
very eloquently explained Sai...Great job. Love your explanation and presentation skills
this is best expleination i found on youtube...
Best explanation of VMs vs containers to date... thanks!!!
Absolute clear and crisp articulation
Thank you! 😃
Thanks for explaining the containers in a very simple way
I comment really rarely - this is the best out there.
This is the best explanation I have ever heard. Great job!!!
Amazing explanantion of what containers are and how they are used. Thank you!
Hi Sai! Greetings from Argentina! I want to thank you for your video! And I want you to know that they are helping us very much with our learnings!
Stefania we are really happy this was so helpful to you! Thank you for watching.-Sai
Thanks for helping me with learing about Containers
No one mentioning how natural you wrote BACKWARDS on the glass? Kudos
See ibm.biz/write-backwards
@@IBMTechnology wow thanks!
Is it me or is anyone else noticing how good his backwards writing is?
Excellent explanation of the benefits of containers. Great overview!
He's really good at writing backwards
Very Well Explained. I am sure I am not going to forget this "vision" about containers. Keep up the good work.
Really good stuff! Perfect for when you'd like to get a basic understanding of the technology and the differences between them!
finally clean explanation on containerization, thank you
You're welcome, Fateh. Be sure to check out our channel for more videos on containerization. 👍
Hey Sai, excellent illustration on containerization. appreciate your time for sharing your knowledge. Thanks !!. Mat.
Men I thought IBM had such really nice content
That is one of the best explanations I've ever seen! Amazing job, Sai. Congratulations!
Good explanation for each term. Easy to understand.
actually, Solaris 10 added Containers in 2004 .. from BSD jails.. but in a production ready context. ;-) Linux C-groups came much later.. as did so many things, once OpenSolaris published is source code.
Thanks a lot. Enjoyed and Understood. It was nice that you explained it with example.
You're welcome!
bro I have been looking for you. Million Thanks
Sai you are a wizard at explaining some of these concepts. Keep it up!
Brilliant comparison and conceptualisation. Keep posting more videos guys. Thanks Sai!!
This helped me out a LOT as an IT recruiter. Thanks!
great video!! do "What is Cloud Native?" next!
Very well explained containerisation concepts.
just starting to learn--very helpful as an overall explanation!
Outsanding skills. You are one in a million!
Thank you, RJ!
Great explanation ! ! but, Where are the manifest, image, and the container located? and what resources are they drawing from?
Wishing you smiles through it all.
coolest thing in this videos is this blackboard
This explanation helped me a lot.
Great video. Super useful
Yes Sir, Thunderbolt Bridge is the Future!!! Thank for This and That!!!
Superbly explained
Great presentation which clearly demonstrates many of the benefits of lightweight containers v heavyweight virtual images
Container is containariazation of container based app. Great!
What a great presentation! Very engaging and doesn't require amazing feats of concentration to learn the information from you! :-) Good work presenter.
Thanks for watching, Chris! Appreciate your feedback.
Fantastic explanation
Nicely explained Sai
Step0 my thinking model (3D model) Step1 its been Container Step2 Provide Space Step3 put LT5 Objects (3D printing)
Another great presentation from Sai, really easy to follow and very personable. Well done!
This guy is really good sharing his knowledge. Thanks!!!
lucid explanation, thanks! Keep posting more.

Best explanation ever
Great overview! I'm subscribed. Looking forward to more presentations.
Thanks for watching and for the awesome feedback! 😃 🎉
very beautifully explained can we have series on docker concepts !!!
Thank you! We appreciate your suggestion and will keep that in mind for future videos.

Awesome explaination!
Thanks great presentation. Can you share what presentation tools you used on this video? It's cool to see a transparent board with you in the background.
Really great presso. However, you did not tell the downsides of the containers vs VMs.
You make it really easy, thank you for the explanation
Very good explanation
Amazing !!! Couldn't have explained it better.
