Cloud computing, an internet based computing where software, shared resources and information are served to devices such as computers, electricity grid. In this details about how the work is getting done is hidden from its users. It describes a new consumption, delivery and supplement model for IT services. It is kind of by-product that provide access to remote sites accessible through internet. Practically applications area of cloud computing not limited. It is latest technology in market.

When someone talks about the cloud computing system, it is very helpful to divide this system into two sections, one is front end and other is backend. They are connected with each other via a network and mostly internet is used for fulfilling the requirement. The front side is the interface for the user and the back end is the cloud section for the whole system.

Front end

The front end of the cloud computing system comprises the client’s device (or it may be computer network) and some applications are needed for accessing the cloud computing system. All the cloud computing systems do not give the same interface to users. Web services like electronic mail programs control some existing web browsers such as Firefox, Microsoft’s internet explorer or safari. Other type of systems has some unique application which provides the network access to its clients. Front end is a technical term which refers to the interface though which a user can use some kind of services, so don’t get confused with this term.

Back end

Back end refers to the some physical peripherals. In cloud computing  back end is cloud itself which may encompasses of various computer machines, data storage systems, servers. Group of these clouds make a whole cloud computing system. Theoretically, any cloud computing system can include practically any type of computer machine program that can be imagined by a human being such as from video games to data processing, software development to entertainment. Usually, every application would have its individual dedicated server for services.

A central server is established which is used for administering the whole system. It is also used for monitoring client’s demand as well as traffic to ensure that everything of system runs without any problem. There are some set of rules, generally called as protocols which are followed by this server and it uses a very special type of software known termed as middleware. Middleware allow computers that are connected on network to make communication with each other.

If any cloud computing service provider has many customers, then there’s likely to be very high demand for huge storage space. Many companies that are service providers need hundreds of storage device with digital in nature. Cloud computing systems require minimum twice the units of storage devices, system needs to keep all the information of its clients. That is because devices like, computer often break down. The cloud computing system must have a copy of all the data of its client’s. Making copy of data is called redundancy.
