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.

What is cloud engineer?

If you’re aspiring to become a cloud architect or a cloud engineer or even a cloud manager right and we’ll finally look at how great learning and retakes together can help you in getting up to that particular no aspired position or your next career transition right so I hope that that the agenda becomes a little clearer if you have any questions to start with I’m happy to answer now do you guys any of you have questions as yet okay so no questions now all right let’s start in that case.

If you look at the first slide here really don’t have a title slide right I don’t have a slide just telling you the name of this particular session and so on just to keep it really simple and straightforward and to drag the point with what the market leaders are saying right so what people like phones and Gartner and even the best of the companies write Microsoft Amazon Google Oracle Alibaba everybody’s saying the future is cloud right.

Now when you say the future is cloud it’s really not entirely true because the present is also cloud right that’s what I mean not just the future the present also is cloud and as you will see in the following slides more than 90% of organizations with small-large and medium are using cloud and some of the other form and not just organizations it’s also individuals individual professionals students at universities everybody is literally using cloud and some of the other form right.

What are people telling here so it’s a four hundred billion-plus dollar market, so globally that’s a huge market to be a part of as a professional as a company it also shows you the amount of investment that people are doing as far as cloud is concerned almost over 80 80 percent of the workloads of enterprise workloads will be sent to cloud by next year right it’s already 2019 so almost all the workloads in enterprises are going to cloud right they already are and they will continue to do so more than 80 percent of companies have a multi-cloud strategy forget using one cloud right.

What we are saying here is four out of every fifth company is using more than one cloud platform right it’s not just one cloud platform, so the approach has matured the number of options has grown the number of use cases people need to use has grown over time and the number of professionals because of all these reasons the number of professionals that companies need will continue to grow right in the next three four-five years now in India specifically the cloud services market has over four billion dollars right.

This will increase definitely with the adoption of all kinds of services that you have on the cloud including advanced services like IoT machine learning AI etc right some of you might even be surprised that even things like satellite imaging will come as a service and cloud right very recently in fact if you read about you know what ADA braces up to recently even if you want the satellite out there to grab some images or do some weather forecasting for yourself even as an individual you can go and get a cloud service for that right.

So that’s really fascinating with what L options do we have on the cloud right so I hope this sets the initial understanding and context of how exciting and how broad and promising this cloud market has become and it is certainly a great time for you if you really interest it in something that’s cloud to become a cloud professional right now let’s understand what is stored in the first place okay there are a lot of definitions if you go to Wikipedia there’s a definition if you go to n is T which is an us-based standards organization there’s another definition but to put it in an in a layman’s term right cloud is essentially a different way of how you consume your IT services right.

Everything else remains the same in principle right when I say that you still have computed you still have you know microprocessors you have storage Ram hard drives network cable subnet all of that stuff as far as computer computers are concerned computing and its science is concerned and as far as programming is concerned all of that is same right so if you’re an infrastructure person a few things will change right.

How you do your job will also change when you talk about cloud but what you want to as he really doesn’t change that much right you still want reliability you still want efficiency you still want scalability still want a backup server you still want you to know geolocation and being close to the customer and all of that right, so the cloud is really a different way to use information technology and its services right so both hardware and software right so when you talk about cloud it’s really a utility model, okay it’s a leased based model it’s a model where you can consume something which is created by somebody else right so, for example, this is very clear examples you can think about electricity right.

If you want electricity tomorrow in a house that you recently purchased you don’t have to set up a power station for that right you can simply apply for a connection and start consuming electricity similarly if you have a new electronic device two more if you buy a new refrigerator or you know even an electric car for example again you don’t have to set up a power station you can simply plug that refrigerator into a socket which essentially is a plug-and-play model and you can start consuming electricity.

Now take this analogy into computing and think about if you wanted an extra machine is there a plug-and-play model right can you just call up somebody can you just go to a website write a digital socket in that case and just plug and say hey I want an extra computer can you give it to me for like two days I want to run an experiment right, so that’s what cloud is you need something either hardware or software right you get it for X amount of time it could be a year it could be five years it could be you know five hours you use it and then you give it back to the owner right.

For example, if you’re not consuming electricity somebody else will right so if you’re not using a cloud resource, of course, somebody else will unless you have reserved it okay, so that’s in very simple terms that’s what cloud essentially is it’s a utility model of computing it’s a model of computing where you can get services both hardware and software from a service provider which we call cloud provider right so it’s the least based model, of course, there are a lot of other aspects to it without going into that I just wanted to you know kind of help you understand what cloud is in very simple terms.

Now, what our company is doing with cloud why is it so famous if you look at the last two decades there have been a lot of revolutions one is the hardware evolution right if you look at the networking equipment’s if you look at the switches and routers that you have if you look at the telecom boom if you look at the data speeds that you have now if you look at the satellite evolution the number of satellites India’s launching if we look at the cost of a hard drive right that has gone way cheaper if you look at the amount of RAM storage that you have in your smartphones.
