Restful Web Service

Major Internet services are required to process a tremendous amount of data at real time. As we put these services under the magnifying glass, It's seen that distributed object storage systems play an important role at back-end in achieving this success. In this chapter, overall information of the current state-of –the-art storage systems are given which are used for reliable, high performance and scalable storage needs in data centers and cloud. Then, an experimental distributed object storage system (CADOS) is introduced for retrieving large data, such as hundreds of megabytes, efficiently through HTML5-enabled web browsers over big data – terabytes of data – in cloud infrastructure. The objective of the system is to minimize latency and propose a scalable storage system on the cloud using a thin RESTful web service and modern HTML5 capabilities.

Distributed Object Systems

Security requirements have become an integral part of most modern software systems. In order to produce secure systems, it is necessary to provide software engineers with the appropriate systematic support. This chapter discusses a methodology to integrate the speci?cation of access control policies into UML. The methodology, along with the graph-based formal semantics for the UML access control speci?ca-tion, allows to reason about the coherence of the access control speci?cation. The chapter also presents a procedure to modify policy rules to guarantee the satisfaction of constraints, and shows how to generate access control requirements from UML diagrams. The main concepts in the UML access control speci?cation are illustrated with an example access control model for distributed object systems.
