Cloud Computing    !!!!!!!! Its a big name companies are moving into now a days. But What actually is cloud computing ??? In simple terms, I would like to explain you is : Accessing, editing, providing & storing all your data and applications for you or your customers from any place in the world. Only the minimum requirement that the cloud ask for is “ The Internet with a computer. Now suddenly the next question rises in your mind is : What are the services vendors provide in the cloud ? Basically, there are three main services that are provided by vendors in the cloud : 1. IaaS : This is the service that resides in the most bottom layer of all the other services. The service is called “ Infrastructure As A Service “. The name itself suggests that in this service, the vendor provides the whole infrastructure (Storage, networking & access) to you for your usage or to upload to web for your customers. They maintain all the hectic hardware and you just need to pay them the rent according to your usage. 2. PaaS : Coming exactly above this IaaS is the PaaS also known as the “ Platform As A Service. PaaS is specifically for Developers. What cloud computing companies like Google do is, they provide the platform of different languages to you like java,Python etc. So that you can develop your app and provide your work to the customers and charge from them in return. Benefit of this service is that the deployment and testing of your app becomes a lot easier. 3. SaaS : A lot more of people now a days might be using Dropbox, Google Drive etc for storing their photos and their other personal stuff. That is nothing but the SaaS known as Software As A Service. So this term will not need any more explanation. You can just use the services that the provider or vendor provides you. Getting your picture clear on the different services, another question that pops up in your mind is : How many types of cloud are there? Well the answer is : 1. Private : One can setup their own cloud with all the required hardware and IT team for maintainance. 2. Public : You can rent a cloud for that and you will have to pay for whatever services you use. All the headache of the IT team and maintainance will be taken care of by the cloud provider. 3. Hybrid : It is a combination of both public and private cloud in which you rent some services by using public cloud and other services reside in your private cloud. So the general picture might be clear to you now on what is actually Cloud Computing and how you can be benefited by using the same
