Transparency and Security Issues in Distributed System

Abstract

A distributed system is a network that consists of autonomous computers that are connected using a distribution middleware. A transparency is some aspect of the distributed database system that is hidden from the user (programmer, system developer, and application program). A transparency is provided by including some set of mechanisms in the distributed system at a layer interface where the transparency is required. A number of basic transparencies have been defined for a distributed system. This paper present an overview of different types of transparency such as (Access, Concurrency, Location, Replication, Failure, Migration, Performance, Scaling, Execution, Configuration, Network, and Naming), and three type of levels transparency which is (Fragmentation, Location, and Local mapping). In this paper, our focus is on understanding the types of transparencies, security issues, fault tolerance and synchronization issues that involved in distributed systems.
