  Cloud based development is a challenging task for several software
engineering projects, especially for those which needs development with
reusability. Present time of cloud computing is allowing new professional
models for using the software development. The expected upcoming trend of
computing is assumed to be this cloud computing because of speed of application
deployment, shorter time to market, and lower cost of operation. Until Cloud Co
mputing Reusability Model is considered a fundamental capability, the speed of
developing services is very slow. Th is paper spreads cloud computing with
component based development named Cloud Co mputing Reusability Model (CCR) and
enable reusability in cloud computing. In this paper Cloud Co mputing
Reusability Model has been proposed. The model has been validated by Cloudsim
an d experimental result shows that reusability based cloud computing approach
is effective in minimizing cost and time to market.
