(Video) What is the cloud Computing?

Hi. My name is Roger and today I would just like to do a brief synopsis of what the cloud is and why we are using the cloud.

Well the cloud we are using nowadays has a number of reasons. 1) It’s inexpensive, 2) it reduces your infrastructure costs and there is no capital [Indiscernible 00:00:20]. And it also becomes not a capex but it is an operational expense.

And that is some of the reasons. It’s no longer a case of you have to spend thousands of dollars to buy a server and another thousands of dollars to find an operating system and then put that over in a corner and you have power to it and Ethernet cables and lots of stuff. So cloud is like buying electricity.

It’s now a resource that we can consume and utilize and then get rid of as we need. But there are three types of cloud. There’s the public cloud, which is everybody. So things like Dropboxes are a public cloud environment.

Office 365 is a public cloud environment. So anybody can use it and anybody can get on it. Then we have a private cloud. Now a private cloud is a cloud that’s supplied by a cloud provider but only one customer can utilize it. And that information on that customer is where this information is going to be stored. And then manage it for you. And then on top of that you got a hybrid cloud. So you can have a bit of public and a bit of private.

Even though at most times they won’t talk to each other but you can have storage in one place. You can have operating systems in another. But what do we use the cloud for? Well, utilization of the cloud, there are three main levels. So we can have infrastructure as a service. That’s where I go and buy a virtual server.

I manage the server but they manage the hardware. So with them looking after the infrastructure, everything that’s above the infrastructure is our responsibility. And again you need people to be able to — who know operating systems, you need people who know applications, you need people who know SQL and Web Data and all of that.

The second component is we have platform as a service. This is where you have – the cloud provider provides the server and the operating system – and that gives you a platform to be able to do everything else that you need to do.

But in both of those cases when it comes to things like antivirus, updates, how you manage it, that’s all your responsibility. And then finally we have software as a service. Software as a service is just the data. So you don’t have to manage every Exchange because Office 365 does — all that does is connect to the Exchange that you have got and then it can send out your email.

Office 365 for instance, for things like Dropbox and OneDrive and any of those Microsoft products that have a component that is in the “cloud”. So you have access to that data because it’s the storage area but that is what the cloud is. So those three things: infrastructure as a service, platform as a service and software as a service is way that derivatives of cloud is coming from.

And you can utilize any components of those. You no longer have to spend $25,000/- getting a server and putting in plugs because you can spend $1000/- a month doing everything you need to do from the server which you’ve got as infrastructure as a service.

Thank you very much.
