Containerization Explained

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

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 👏👏👏

[@indiclock1577]

What a clear and crisp presentation Sai. The way IBM is advocating for Cloud is totally appreciable. count me in...soon.

[@lcsxwtian]

Absolutely, one of the best explainers I've seen so far. His handwriting is gorgeous as well.

This video 'Contains' almost everything that will help to get a good overview of Containerization. Great Work!

[@ponessa]

Great high-level overview of containers vs VMs.

[@reeteshhurkhoo9231]

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.

[@cevxj]

I think they flipped the video.

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 .

One of the ONE trainers, Sai Vennam. Thank you! Great content in all of your videos.

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 :)

[@johnstory9981]

I really love these videos; great information presented cleanly and concisely.

[@bjaMoke]

Finally... a clear run-through of containers. good lad

[@ReflectionOcean]

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

[@justinching9317]

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.

[@rmaleshri]

before watching this, didn't have any idea about containers. Now its all clear. thanks.

[@DanishAnsari-hw7so]

The comparative example made it much easier to understand the concept of containerization.

[@blackmagic5343]

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.

[@KaziMeraj]

Totally to the point! Glad I viewed this video.

[@kavitasoni4947]

Explained the concept in Simple and Crisp way.... Amazing work Sir......

[@freebk161]

I liked the way you compare VMs with Containers. It made it very easy to understand the fundamentals with details. Thanks!!

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.

[@bsummer]

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

[@dannyfogel9156]

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?

[@Daantjec1]

Really good stuff! Perfect for when you'd like to get a basic understanding of the technology and the differences between them!

[@rameshrudra861]

[@sub-harmonik]

It's true that if you run docker containers on windows or macos it still has to run in some kind of linux virtualization though, right? I think the virtualization would still be shared between the containers at least though, instead having to be recreated for each unit.

[@Billy-sy4bt]

This might be a dumb question , but isn’t hypervisor doing the virtualization on the hardware and not the host OS?

[@grownupgaming]

2:56 Are all incompatibility problems resolved when dev/customer apps/libs are the same? Or some issues get squashed by making dev/customer's guest OS be the same as well?

[@davidlouda3305]

Thank you for this video. One question - images are often build upon an OS-base such as "FROM ubuntu:22.04" etc. Even though they are more ligthweight, they are still OSes. In your schema, wouldn't it be more accurate to keep the OS layer for containers too? The difference between VMs and conts. could be then attributed to the kernel. (VM its own drivers etc?)

[@m8111806]

Container is containariazation of container based app. Great!

[@amzxa7574]

When we talk about "the shared pool of resources", does it refer to the RAM and CPU?

[@jag7450]

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

[@BodySurfer119]

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.

[@awjones6050]

Great explanation ! ! but, Where are the manifest, image, and the container located? and what resources are they drawing from?

[@Pruuc]

You mentioned applications might work on your local machine during development but break when pushing to your VM, which screws up CI/CD, however I missed why containers fix this. Why is that?

[@嘉然今天吃战斧牛-u1h]

Because of its portability, your application is running in a container, which is an isolated environment which provides everything you need for running an application, so you just need to build an image for your application once, and run it everywhere, whatever it is in physical server, virtual server or cloud environment. And it also standardize the process of deployment, you just need to run a command docker build/run to deploy.
