From the last thirty years the trends within the Computing trade is towards Distributed, low price unit, and high unit volume product. additional computer code development activity is changing into a lot of decentralized thereby increasing more development efforts for organizations. The performance of system has enhanced drastically with the inclusion of data processing and Multi computing. This paper presents a scientific literature review on the problems, Recent Innovations, Challenges and advantages of Distributed Systems. With AN example. This paper presents a the safety problems related to those systems. Four usually used distributed systems were thought-about for careful analysis in terms of technologies concerned, security problems sweet-faced by them and resolution projected to avoid those problems. Finally the safety problems and also the solutions were summarized and compared with one another. This paper is additionally aimed to grant a report on the Distributed Computing Technologies in activity.
