Service oriented architecture is a popular service business that processes client application software and stores client data. Cloud computing centres provide a collection of services on a for-use basis. Before discussing the complete cloud infrastructure and service management, it is important to understand the concept of cloud computing in more detail, including its characteristics, benefits, services, and deployment models. The cloud computing services providers keep track of the actual customer usage with a metered service system. They then provide billing and chargeback information for the Cloud resource used by each consumer with a detailed usage file available for customer inquiry. Operating a corporate data centre also involves employing and training a variety of technical personnel. Among these are operational personnel for running the applications, supporting the networks, and proving help desk support to end-user customers who access the data centre to make use of the offered computing services.
