  Abstract: Cloud Computing is rapidly emerging and the new development in Information Technology. There are many patterns, or categories, in the world of cloud computing that are needed for the enterprise architecture. Some of the categories of services are storage, database, information, process, application, platform, integration, security, privacy, management/governance, testing, and infrastructure. Scalability is one of the important features applied on any of the services. The existing analysis specially focuses on Architectural and policy Implications without exploring the data privacy issues. In this paper, the application scalability and data privacy initiatives on various services in cloud environments are presented, with an overview of the trends they follow.
