List three architectural patterns that have been widely used in fault-tolerant systems. {Ans: · Protection systems · Self-monitoring architecture · N-version programming}What are the disadvantages of RESTful approach? {Ans: It can be challenging to design a set of RESTful services to represent a service that has a complicated interface and is not a simple resource. Services users must rely on informal documentation to understand the RESTful interface as there are no standards for its description. When using RESTful services, one must set up his/her own infrastructure for maintaining and monitoring the quality of service and service reliability.}Explain the two important assumptions made by resilience engineering. {Ans: · Resilience engineering assumes that it is impossible to avoid system failures and so is concerned with limiting the costs of these failures and recovering from them. · Resilience engineering assumes that good reliability engineering practices have been used to minimize the number of technical faults in a system. It therefore places more emphasis on limiting the number of system failures that arise from external events such as operator errors or cyberattacks.}List the five process stages to develop a system from concept to detailed object-oriented design. {Ans: · Understand and
