How the services of the cloud get delivered to the customer ?

And there's basically three different ways, three different models for delivery.


Let's look at infrastructure as a service.

There what we're doing is to provide computer hardware in terms of processors, disks, network. We are allowing people to use those services, to rent them. We're providing a infrastructure as a service that you can go to, you can declare how many computers you want, what are the hardware facilities you want. Then it is up to you to put your own software on top of that system, even your own operating system on top of that system. And you just provide your customers with all that software, but you've rented the hardware.

The next level is Platform as a Service, PaaS.

Here what you're doing is deploying customer-created applications. So the applications are running on what you're providing in terms of operating system and hardware, as a cloud provider. So, App Engine is an example. Google provides App Engine, you write your application with App Engine. And all of a sudden, you can run from 1 to however many, 200,000, 600,000 machines on Google.

Then we have Software as a Service. Here what we're using is the user's applications, we're providing the user applications over a network and they would just interact with those applications.

So for example, if you're doing email, if you're doing Office 365, there are companies out there that are making huge amounts of money out of providing services to customers. And one of them is SalesForce. What SalesForce does, it provides customer relationship management software, amongst others. It tailors that, it has a whole suite of software that allow customers to pick and choose particular forms of CRM, or whatever, and allows them to use that for their businesses.
