It has been shown that the current SOA-Based approaches used to improve the  reusability of SaaS applications in Cloud Computing don{u2019}t provide SaaS application  developer with a simple and understandable reusable and customizable model. This leads  SaaS application developer to: a strict model that can{u2019}t be customized easily to meet  each tenant{u2019}s unique requirements, and can{u2019}t be stored in a database to be reused in the  future   aIssued also as CD 4aArchitecture 4aComputing reusability  4aService oriented 0 aAbdelaziz Khamis , eSupervisor0 aAshraf Shahin , eSupervisor  uhttp://172.23.153.220/th.pdf
