For a moment, I was super impressed that he could write backwards!
smart board technology
me too
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!)
@@epretorious Thanks, I was having a tough time visualizing what was happening here.
notice they all left-handed
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 video 'Contains' almost everything that will help to get a good overview of Containerization. Great Work!
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.
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.
Great high-level overview of containers vs VMs.
My man is killing it. I'm gonna watch the entire playlist. Thank you in advance!
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 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 :)
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.

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.
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 .
Wow this dude is great I need him for my exams
One of the ONE trainers, Sai Vennam. Thank you! Great content in all of your videos.
I really love these videos; great information presented cleanly and concisely.
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
before watching this, didn't have any idea about containers. Now its all clear. thanks.
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.
I liked the way you compare VMs with Containers. It made it very easy to understand the fundamentals with details. Thanks!!
The comparative example made it much easier to understand the concept of containerization.
I'm most impressed by the flawless backwards writing
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......
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!
We're so glad to hear this! And thank you for the appreciation! 👍
Finally... a clear run-through of containers. good lad
One of the best explanation of why containerization is important
Informative overview of the relative merits of VMs and containers. In integrated modular avionics, some safety-critical RTOS implementations have been using containers of kinds (ARINC 653 partitions) since around 2003. It's interesting to see how similar concepts can be applied to deeply embedded and cloud native at different scales.
He's really good at writing backwards
Really good stuff! Perfect for when you'd like to get a basic understanding of the technology and the differences between them!
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
Thanks.
You explained such way that I could capture it easily.
Simply straightforward.
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
Wishing you smiles through it all.
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
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!
He made containers so amazingly simple.
I comment really rarely - this is the best out there.
Absolute clear and crisp articulation
Thank you! 😃
Thanks a lot. Enjoyed and Understood. It was nice that you explained it with example.
You're welcome!
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
Brilliant comparison and conceptualisation. Keep posting more videos guys. Thanks Sai!!
Best explanation of VMs vs containers to date... thanks!!!
this is best expleination i found on youtube...
I just realized that you had to write backwards for this. Awesome.
They filp the video. He is right handed
Thanks for explaining the containers in a very simple way
That is one of the best explanations I've ever seen! Amazing job, Sai. Congratulations!
Amazing explanantion of what containers are and how they are used. Thank you!
This is the best explanation I have ever heard. Great job!!!
Men I thought IBM had such really nice content
This video really helped me understand containers....thanks Sai Vennam!
Very Well Explained. I am sure I am not going to forget this "vision" about containers. Keep up the good work.
No one mentioning how natural you wrote BACKWARDS on the glass? Kudos
See ibm.biz/write-backwards
@@IBMTechnology wow thanks!
Thanks for helping me with learing about Containers
lucid explanation, thanks! Keep posting more.
Yes Sir, Thunderbolt Bridge is the Future!!! Thank for This and That!!!
Is it me or is anyone else noticing how good his backwards writing is?
finally clean explanation on containerization, thank you
You're welcome, Fateh. Be sure to check out our channel for more videos on containerization. 👍
Great presentation which clearly demonstrates many of the benefits of lightweight containers v heavyweight virtual images
This helped me out a LOT as an IT recruiter. Thanks!
Sai you are a wizard at explaining some of these concepts. Keep it up!
Something I don't get is - if we want to just run applications and choose vm, why do we need multiple virtual machines for each app?
Container is containariazation of container based app. Great!
great video!! do "What is Cloud Native?" next!
Excellent explanation of the benefits of containers. Great overview!
Great video. Super useful
Good explanation for each term. Easy to understand.
This guy is really good sharing his knowledge. Thanks!!!
Great informative explanation. Thank you
Hey Sai, excellent illustration on containerization. appreciate your time for sharing your knowledge. Thanks !!. Mat.
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.
Perfect, simple and straightforward
Glad it was helpful Carolyn. Appreciate you watching!
just starting to learn--very helpful as an overall explanation!
Every single video that I watch actually gets me more irritated at the lack of some details. The biggest missing details are these:
* Storage - when my application says to save a file to disk, where does it store it? Am I able to see the underlying OS filesystem? Or it creates a home directory like SFTP and prevents you from seeing the underlying filesystem?
* How EXACTLY does docker resolve the issue where something runs on my computer, but doesn't run on someone else's? If my app runs great on my computer, but for whatever reason, it doesn't run on another computer, how does docker resolve that issue? If I were to put docker on that computer that fails to run, it will magically solve that issue?
* When talking about the host OS, please specify what do you mean by that? For instance, I can run VMs two different ways: 1) Have a Dell physical hosts that runs vSphere, which allows us to spin up VMs. 2) Have a standard machine running Windows 10 Professional, and setting up multiple VMs via Hyper-V.
* When talking about running "applications", can you specify what you mean by it. Can I run Microsoft Word on it? Can I run a video game via docker (I know this is a rhetorical question, but imagine if it wasn't)? Do I only run web apps there? Or can I run command line applications?
So is the host OS a typical operating system like Windows 10, Ubuntu, even MacOS? Or it is Hypervisor OS like vSphere, ESXi, Nutanix?
Step0 my thinking model (3D model) Step1 its been Container Step2 Provide Space Step3 put LT5 Objects (3D printing)
Very well explained containerisation concepts.
Love the series
Thanks, very simple and straight to the point!
Thank you, Javier!
Another great presentation from Sai, really easy to follow and very personable. Well done!
Thanks it was a very nice explanation.
IBM videos = 👍🏻
You make it really easy, thank you for the explanation
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.
Totally to the point! Glad I viewed this video.
bro I have been looking for you. Million Thanks
This explanation helped me a lot.
coolest thing in this videos is this blackboard
Nicely explained Sai
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.
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
Outsanding skills. You are one in a million!
Thank you, RJ!
Wow, great explanation!
Yes, Indeed!
Great explanation!
In the first case, Could we don't use VM and just deploy applications on host OS? We don't need to install Linux VM, just use Linux Server.
great explaination!!!!!!!!!!!!!!!!!!
Amazing !!! Couldn't have explained it better.
Thank you for watching and for your feedback! 🙏
Really great presso. However, you did not tell the downsides of the containers vs VMs.
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.
Very good explanation
I think I get, how it is possible to write like this:
- Left-handed(?) writing skill tips and pocket location on a shirt
- Glass of course
- Plus post editing
