How to work on multiple cloud platforms?

Now offering as well right and for the question of who is using cloud today like I said more than 85% of the companies have been using cloud and not to multiple cloud platforms but if you also look at the right scale 2018 state of the cloud report almost 96 percent of the respondents are using the cloud right in what form and shape that is not really the concern here but what you really want to understand here is how many people are using cloud and the answer is almost everyone.

Let me take a pause here let me see if you have any questions are you are okay so I have I think I have two questions from chat Anya Japanese these are I think real related questions would you mind if we take them in the second half of this session just in a little of time when we talk about specific skills for couriers yes please stay tuned I’ll definitely answer your question, okay Sheet has a question what is an idea to use private cloud over public cloud our societal I’m assuming you’re asking when would you use private cloud instead of public cloud right okay.

So essentially there are two reasons why you would use private cloud right there are multiple use cases of course if you just go to Google and try to search what’s when to use a private cloud you will get multiple use cases, but there are essentially two factors to it one is what kind of business are you in it so for example if you are a bank right you might go for a private cloud set up if you are if you’re a forensics laboratory you can go for a private cloud if you’re a security agency like police like a CBI like an FBI you might want to go for a private cloud shut up.

When businesses are concerned about the nature of the data the security of the information the security of the infrastructure and the control that they want right that’s when the private cloud is essentially used right and also if you want to customize a lot of things according to yourself so for example, if you wanted to create a cloud where you know the type of virtual machines available would be as per your specification right all of them in that case you would go for private cloud so essentially it’s about control and security and customization right if you want all of that to a high degree you would want a private cloud that’s briefly about it Septal does that help you okay.

I already have a thumbs up from you so I’ll take it as a positive thing okay Jain Prakash is asking how do you differentiate between private cloud and public cloud in cloud okay, so that’s already a question which can confuse anybody by the way but yeah good question as far as this point in time is concerned what I will suggest you when you look at a cloud infrastructure to answer your question he should again ask a question who is going to use this cloud right you should ask of who is going to use this cloud infrastructure if the answer to that question is everybody can use and subscribe to this cloud publicly it’s a public cloud right.

If the answer is hey people only in my organization can use this cloud infrastructure that becomes a private cloud it’s not open to everyone yon does that answer your question, in that case, it becomes a private cloud sun Prakash this help you does that answer your question [Music] yes you are right cloud is essentially based on the idea of multiplexing and virtualizing and sharing resources but sharing resources does not make it public you can share the sources within a development team also right which is the closed team yeah.

Sharing a free source and resource pooling is a generic computing concept and it happens everywhere, but the public cloud is essentially about who can subscribe to your cloud services right is it the public is it individual or is it anybody if that is true then it becomes public cloud ok Shiva is asking please tell me about virtualization Shiva a good question what I will do is I will quickly tell you about what virtualization is and we’ll keep it limited in the context of this particular session right because it’s a technical topic and it might you know the kind of confuse a lot of people, so virtualization is essentially about consolidating your hardware right as well as software so if you look at a single operating system just to give you an example right.

Let’s say you have Windows on your laptop or desktop and if you wanted to use Linux right the first approach and the first brute-force approach is to make two partitions in your hard drive and install Windows and Linux as well right and you log in separately to both of them right so when you are using Windows you can’t access Linux files when you’re using Linux you can’t access Windows files and vice-versa now virtualization is a technology which will help you create a Linux machine within the windows’ ecosystem right without create Hard well partitions essentially at a fundamental level and also allowing you to switch between Linux and Windows right at the same time without rebooting.

So that is OS virtualization operating system virtualization and you also have hardware virtualization so essentially it’s about sharing software or Hardware resources between multiple tenants right multiple uses Shivani does that help you at a high level right we’ll need more time to understand yeah yeah so just as a basic definition I think it helps you okay great all right so let’s okay since the questions are all done.

Let’s move on with the next slide right so continuing our discussion here as I was saying the growth in the cloud is not just happening globally it’s also happening in India now the numbers here are a little dated but to give you a sense of the trend if you look at the green sections here now the green sections represent traditional data centers right and traditional data centers are the ones where virtualization is not used right where cloud-based technologies are not used and the green will keep reducing right it has gone much further again and both the Blues that you see here are either public or private subsystem, so the message here is right.

There are a lot of traditional data centers in the world more so in India and we need to transform all of these data centers from traditional set up to a virtualized and cloud-based data center-right, so that is also propelling the growth as far as cloud is concerned the adoption trend again is very very strong you know more than 90 percent of the folks are using cloud and some of the other forms now we’ve spoken enough about the market itself.

We’ve spoken about a lot of numbers you know what is the trend how many people are using flower how many companies are using cloud and so on let’s take a to from here and talk about what about the technical aspects of you know what what’s driving cloud so if you thought about cloud as a place where you can just get virtual machines or some extra storage like Dropbox or something else where you’re right but if that is all you think about the cloud that’s a very narrow perspective right today cloud is about more than hundreds of services right when I say service it is essentially an information technology concept and item that you want to use so, for example, a hard drive.
