Cloud Computing is latest technology in IT field, which distributed computing over a network where a program or application may run run on more than one computer at same time.

Ex:- Best example of cloud computing is online gaming. We thought i am only play this game but at the same time same game running on a number  of computers.

Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing data storage, processing and bandwidth.

An another  example of cloud computing is Yahoo email, Gmail,  Hotmail or any other mail. All you need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud  and is totally managed by the cloud service provider Yahoo , Google etc. The consumer gets to use the software alone and enjoy the benefits.

Cloud computing is broken down into three segments:

1.  Infrastructure as a Service (IaaS):  It΄s the demanded infrastructure for the provisioning of cloud servers.  Basic unit of IaaS is a Cloud Server without whom none cloud service would be possible.  What makes Interworks unique is the provisioning of not  just a Virtual Private Server (VPS) but a Cloud Server with capabilities like failover, escalating and cluster (the capability of combining cloud servers so a farm structure with active/passive or active/active cluster is possible) and dedicated resources (for example dedicated memory versus shared memory that is used by virtual private servers).   
2. Platform as a Service:  PaaS provides all the infrastructure needed to run applications over the Internet. Inter-works provides PaaS composed by two sections.  The first section includes the operational platform Web Serve. With Web serve, performing administration and distaned parametralization of IaaS as well as SaaS applications installed in Iaas is feasible.   The second section includes APIs (Application Programming Interfaces), supporting connectivity of a system (eg web service) with server capabilities. For example, an IT Manager doesn't have to set up a mail server from scratch, but he can use the specific API of PaaS to meet his need.
3. Software as a Service:   Its software applications operating as a service via the internet, also known as On Demand or Web Based or On line Software.   Inter-works, as Microsoft S+S Incubation Center (MIC) provides SaaS Applications of ISVs hosted at MIC.

Advantages of Cloud Computing:

Reduce IT cost:  Moving to cloud computing may reduce the cost of managing and maintaining your IT systems. Rather than purchasing expensive systems and equipment for your business, you can reduce your costs by using the resources of your cloud computing service provider. You may be able to reduce your operating costs because:

• the cost of system upgrades, new hardware and software may be included in your contract
• you no longer need to pay wages for expert staff
• your energy consumption costs may be reduced
• there are fewer time delays.

Scalability: Your business can scale up or scale down your operation and storage needs quickly to suit your situation, allowing flexibility as your needs change. Rather than purchasing and installing expensive upgrades yourself, your cloud computer service provider can handle this for you. Using the cloud frees up your time so you can get on with running your business. 

Collaboration : Collaboration in a cloud environment gives your business the ability to communicate and share more easily outside of the traditional methods. If you are working on a project across different locations, you could use cloud computing to give employees, contractors and third parties access to the same files. You could also choose a cloud computing model that makes it easy for you to share your records with your advisers. 

Flexibility: Cloud computing allows employees to be more flexible in their work practices. For example, you have the ability to access data from home, on holiday, or via the commute to and from work (providing you have an internet connection). If you need access to your data while you are off-site, you can connect to your virtual office, quickly and easily.
