time is lost that's the same thing as d2 like more journey which is exactly this so if you have a longer journey to cover you have it will take you more time what else luggage I mean if you can convince the driver then it's going to be fine what else have you ever felt one thing that is missing from as compared to a non shared cab versus a shared cab one major thing privacy yes privacy is missing right there are more people more possibilities of an argument isn't it I had an argument once in a cab with a girl I just asked her why she was late and she was like आप कोन होते पूचने आले आप उबर को बोलो ये वो I mean her being a girl is irrelevant thing here it could have been with anyone but what are the advantages why do you still take a shared cabin you agree that there are issues but why do you take the shared cab what money money is the issue right you got to save the money right you got to buy that bike that phone right need to save the money what else is the advantage here less traffic do you see that if you travel in a shared cab this is the picture I just shot few days ago in front of the IT main gate you can see if you take a shared cab there are less number of cabs on the roads see the other side of the road less number of cabs I mean I'm not saying there are all shared cabs on the other side but let's just say I mean you're getting my point right two people have two cars instead of that if you share it one car right instead of two cars you have one car so there is less traffic less number of cars less amount of fuel used and less pollution right so there is a less you know smaller footprint of the whole thing so now coming back to the disadvantages the detour right sir so you said that there is a detour what if all the passengers have the same pickup and drop locations is the detour still going to be a meaningful thing it is not and the time factor also will go simultaneously right if there is no detour means all the passengers are going to take the same time to travel which is equivalent to the time that you would have taken otherwise in a non shared cab correct what about the privacy thing right the privacy issue is still there right what if somehow you can make yourself invisible from the other people and likewise for them no one can interfere with you and you cannot interfere with anyone while you're in the shared cab the food for thought right that's why literally food for thought so let's say these three people take a shared cab you know these three people are right who are these three people yes who is the first one is he who is the first guy I am sure a lot of you like I saw people you know I heard them saying the Marvel fans you know these three people are right they take a shared cab now this is the fancy car that came you know as a shared cab so they had this driver for the shared cab he will sit in his driver's seat then he goes to pick up the first person first person happens to be the Hulk Bruce Banner he comes he sees the car he's like I'll sit in the first seat he sits there now is the isolation part that I'm trying to explain when the car goes to pick up the second person what does the second person see nobody in the car because it's isolated right he cannot see anybody he cannot feel or sense anybody and similarly for the other person the other person happens to be Tony so he just comes he sits in the car again the car moves ahead wants to pick up the third person the third person happens to be the God so even he when he sees the car it's empty he just he wants some space to relax and he wants a larger space also so he goes at the back of the car so each of them in their minds they feel that they're the only ones in the car right I mean look at this Tony feels he's alone Banner feels he's alone and even Thor feels he's alone right but what is the reality you and I know the reality they're all in the same cab they're isolated they don't know about each other's existence exactly the same thing is the technology that your internship if you go for internship under my mentorship then this is the technology that you'll be working with it's called Docker Docker will provide you the isolation for your different services on the same operating system now does this sound familiar to something you've already seen running multiple things on the same operating system multiple operating systems on one operating system something yeah virtualization right so there's a huge huge debate now this will be your homework when you go back this will be your homework you can Google what is the difference between Docker and virtualization so it is similar to virtualization but there are lots of subtle differences that you can Google out and find out but let's discuss more so this picture it'll give you a rough idea about I mean of course I can't expect you to read the whole image I know sitting here in a few minutes but this is the Docker ecosystem so what are the possibilities with Docker there are dev tools there are different operating systems there is infrastructure there is networking there is storage there is security logging is there all these things are packaged in something a service known as Docker which will help you ship your programs your software now why is this why is this important why am I even talking about it the reason is I'll just put this slide up and I'll let you read it at the same time I'll talk about why I'm discussing this so developers they love their code but do you know that as a developer in practical life you're going to spend a lot of time doing things other than coding for example somebody says that you know you wrote this code on your system but it's not working on my system that's the basic the number one problem someone says the dependencies that you've installed they're not available for my operating system for example pip it doesn't work well on windows what are you going to do something is not working on Mac how are you going to test it you're not going to run it run a development or a production thing on that OS but you want something to test it right you're writing some code and your boss uses Mac now he says it doesn't work on my system you spend a couple of days just going through the dependencies even though it's working on your system and then you go back to him two days later and again he's like no it's not working you're frustrated you go back you you hate your job you hate being a developer right that's why docker comes into the picture and docker will save you from that because what docker does is it's the shared cab for all those services so what what docker helps you is that it'll take the services and you can ship it with the cab so you can take Tony Stark and ship him with his own cab you can take Thor and you can ship him with his own cab anybody who wants to use Thor he has to use it from within the cab the cab itself will be invisible docker itself is going to be totally oblivious to the whole thing you're not going to notice that something is there it's just going to work so I already gave you a homework I'm sure you'll be you'll hate me for that because your teachers already give you enough homework but still go back and Google about what is the difference between docker and virtualization and that's it so the shipping service for developers the shared shipping services you will get your own ship but we know that there will be other people on the ship also so you can just email one of us my name is also Gaurav and my colleague's name is also Gaurav so that's why our team's name is G-square team so you can email us in case you have any doubts but hopefully you won't have any doubts if you Google that virtualization versus docker oh what was that did the God do something anyway thank you
