Assignment

Below are some questions related to the course of (Distributed Systems). Answer each question and provide support of your answer from legitimate sources (ACM or IEEE journals and conference papers. Use APA format. Refer to the course content and the textbook. Write at least two paragraphs for each question and elaborate in it. Give at least one source for each question.

1. Explain in details why heterogeneity is a challenge for distributed system designers. Give two specific examples.

2. Explain why/why not HTML, URLs and HTTP may be classified and used as core technologies for general-purpose client-server computing?

3. How does the openness of a distributed system impact its design? Give a specific example.

4. Most of distributed system discussions have yielded some relevance to system performance and thus relate to concept of quality of service. Discuss a mechanism in the life cycle of distributed systems and applications that supports the provision of quality of service.

5. In the course content we have highlighted the value of a standard communication protocol that provides a base for distributed activity and the challenges of heterogeneous components. Given the different transparency techniques highlighted in the course materials, choose one and give an explanation of how it applies to a heterogeneous system, the value, and how the transparency is accomplished (include hardware and software mechanisms and any decisions that are based upon them).

6. Within a distributed system many services are required to support the processing infrastructure. As these systems are extended, scalability of these services is critical to the success of current and future applications. Given a shared resource that has the potential for frequent access from many distributed processes, provide an example that includes the resource and a technique that addresses the scalability in this situation.
