Cloud architecture as a term encompasses the system architecture of all the software’s that form a crucial part in the delivery of cloud computing and generally includes the communication of multiple cloud componentswith each other over a messaging queue(has loose coupling mechanism). Cloud servers provide a significant improvement in virtualization with its elasticity feature that implies intelligence in whether to use tight or loose coupling as the mechanism to be applied. Another provision that differentiated cloud server from the traditional servers is the “Intercloud”, which implies an interconnection through cloud of clouds and an extension of network of networks Internet.

A cloud computing system architecture is based on two sections: the front end and the back end that have connectivity together through a network, usually the Internet. The side that computer user forms the front end whereas the cloud section of the system is regarded as the back end of the system know more at The system leverages the use of either applications designed uniquely for the system or the existing we browsers like internet explorer, MozillaFirefox, etc.

Several providers also take the use of computers, servers and data storage systems to create the Cloud together at the back end of the system. This signifies the use of dedicated servers for cloud computing services and can practically include anything imagined ranging from data processing to the video games.

Then there is also a central server that is designed to follow a set of rules designated as protocols. The centre acts as the heart and is responsible in administering the system and monitoring traffic and client demands to ensure smooth application of the system. Middlewareis also to create a bridge between the networked computers for communication. Virtualization technology provides the efficiency for reducing the need of large number of physical machines by increasing the individual servers output.
