Distributed systems have multiple events across different servers. Many events depends on each other. However, some events have concurrent relationship. a. What is the role of events ordering and why it is important? b. What if, a data center does not implement the mechanism to order the events. How this will effect the system? c. How, time synchronization helps to order the events? How effective this approach is ? d. What is the best algorithm to achieve 100% time synchronization? Explain the complete methodology of the algorithm, also describe shortcomings if there is any. e. What is the best recommended approach to order the events in distributed system. How it is effective?
