 So, hello everyone, I am Irfan, I work as a lead QA in one of the education startup in Mumbai called as UpGrad.com. Basically, we are an online learning platform. We help other startups grow and learn. So, if you are planning to do that, just browse us sometime. This is my Twitter handle critical. So, the icon is of one of the tools related to Docker. He is just a very naughty octopus. He is just trying to catch these Elenium tools and he is trying to pack it in containers so that he can actually ship things properly. How many of you have worked with Docker? Let's work with Docker. So, I think we can start now. So, you might have heard a lot about testing as a practice, then testing as a service, testing as a container. So, what is it? Something new or the same thing, just wrapping in new words. Let's see and find out. So, why do I need to think about Docker? Why should I even think about it? What is the use for me? Or for you? Like, you guys are coming. What is the use? What will happen to you after this talk or demo? So, we are here. We all are Gangadhar. So, this is a normal guy like me. I have a bad side. I have a good side. Nothing is focused. Like, I have a lot of energy but nothing is focused. I have a lot of things but nothing is packaged into right format. Now, if I know something, how many of you know about Shaktimaan? So, in 97, 98, I used to be a fan of Shaktimaan. I used to wonder what makes Shaktimaan different from Gangadhar. Like, he is the same person. And what I came to know after few years of my childhood research is, it's all about packaging.
