1.	Explain how cloud service model change the way we use computers.
Answer» It is an emerging computing technology. Here with the use of Internet and central remote servers to maintain data and applications. Example for this is Email service, Oce Software(word processor, spread sheets, presentations, data base etc), graphic software etc. The information is placed in a central remote server just like clouds in the sky hence the name cloud computing. Cloud service models (3 major services) (1) Software as a Service (SaaS): A SaaS provider company provides more services on demand such as they allow to access both resources and applications. Examples are Google Docs, Adobe creative cloud, Microsoft Oce 365, Facebook.com etc. (2) Platform as a Service(PaaS): A PaaS provider company provides subscribers access to the components that they, require to develop and operate applications over the Internet. Example : LAMP platform(Linux,Apache Server,MySQL and PHP), ASP.NET, PHP and Python, Google’s App Engine, Microsoft Azure, Force.com, etc. (3) Infrastructure as a Service(laaS): It provides basic storage devices and computing capabilities as standardized services over the network. Example: Amazon Web Services, Joyent, AT&T, GoGrid etc. It’s offloading and centralizing applications for teams to work on applications collaboratively, more efficiently, and removing a huge burden of operating services. The concept isn’t new, it’s just a fresh coat of paint on the old school time sharing and mainframe style computing systems. As for changing the way we work, it’s allowing companies that have neither the inclination nor need to operate their own services and datacenters. Businesses can now spend more time doing actual productive work rather than spent time running the systems that allow them to work. Also especially for the small to midsize companies it’s allowing them to run applications and services that were simply logistically and financially impossible to operate before on premise.
