Infrastructure as a service

In Infrastructure as a service ,the service provider provides the necessary servers,hardware and networking components to an organisation for a fee.The organisation in turn installs the necessary programs in the service provider's server and uses them.The service provider is responsible for the maintenance of the servers.

Platform as a service

In Platform as a service ,the service provider provides the necessary softwares and the tools for creating softwares which are installed in their server to an organisation for a specified amount.The organisation creates the necessary softwares on his platform and uses them.Its like renting in a house which has all the necessary things.

Software as a service

In Software as a service , the applications hosted in the service provider s server are made available to customers via the internet.The provider also interacts with the user through a front end panel.The provider provides the necessary support to the customer.The services range from e-mail to data processing.

Advantages of cloud computing

I really appreciate your contribution to explain cloud computing. No doubt, this phrase will become a common concept in the near future, but it’s still confusing for many. I appreciate the graphics near the top of the Hub to clarify the benefits of cloud computing. Pictures (or graphics) are worth a thousand words. I look forward to your future contributions.

With cloud computing, you eliminate those headaches because you’re not managing hardware and software—that’s the responsibility of an experienced vendor like salesforce.com. The shared infrastructure means it works like a utility: You only pay for what you need, upgrades are automatic, and scaling up or down is easy.

Cloud-based apps can be up and running in days or weeks, and they cost less. With a cloud app, you just open a browser, log in, customize the app, and start using it.

Businesses are running all kinds of apps in the cloud, like customer relationship management (CRM), HR, accounting, and much more. Some of the world’s largest companies moved their applications to the cloud with salesforce.com after rigorously testing the security and reliability of our infrastructure.

As cloud computing grows in popularity, thousands of companies are simply re-branding their non-cloud products and services as “cloud computing.” Always dig deeper when evaluating cloud offerings and keep in mind that if you have to buy and manage hardware and software, what you’re looking at isn’t really cloud computing but a false cloud.
