Abstract:      The cloud computing emerges as a new
computing model which aims to offer consistent, custom-
made QoS assured dynamic computing environments for end-
users. This paper includes the definitions, features, CDLC
and services provided by the cloud computing Technology.
Keywords: Cloud computing, Platform as a service,
Performance, Software as a service, CDLC.
