You probably have seen Google docs or any web app, well in all web apps there is one common thing that they run on some remote servers and use their resources but still you can use them as they or we can say they will create the feeling that they are installed in our own system.
In cloud computing you can say that there are web apps are SaaS but as cloud computing is just a marketing term. All there web app providers were present even before cloud computing name came into market, now they are just changing name of their services by adding cloud to it or adding taglines like Into the cloud! but in real cloud computing the implementation of saas is bit different.
As we earlier said cloud computing is also on-demand computing... Suppose there is some CRM software which is very high cost and you need such a software for your company. But you don't want to pay for the times when you are not using the software or you may just need it for a particular time according to your need. You can buy this software from a local CRM provider which originally buys the full licensed version of the software and provide it's client with this software according to their needs.
The main thing in this is resources like CPU, RAM, processing power even the internet speed are of the server's and client can use this even he do not fulfill system requirements for the software.
In our project we will be providing as many software as you like to clients but the condition is the software must be installed in your operating system because the client will just get a live interactive personal display of your installed software.
For ease we will be providing Firefox to client as it is preinstalled in your redhat. You can later add as many softwares as you like.
In case of firefox note that when client will launch firefox which will be not installed in his os, will use the internet speed of server.
Fun will be more when we will give Gnome terminal of rhel7.2 to a windows client.
