The Software Engineering module, in all its parts: syllabus, guidelines, lectures, discussion questions, technical notes, images and any additional material is copyrighted by Laureate Online Education Module: SE Seminar 7 Seminar 7 Distributed Software Engineering and Service-Oriented Architecture Study Chapter 18 and 19 Seminar 7 provides you with an understanding of the fundamentals of designing and implementing distributed software systems. The idea of software as a service will be introduced. Web services and service-oriented application development are studied. Part 1: Distributed System Architectures Business e-environments are evolving such that it is often impossible to know who is doing what and where. Today, many of our corporations operate globally, 24 hours a day, seven days a week. We see a rapid melding of a global economy. Work and tasks are quickly updated and changed based on global information, often reducing business cycle times to a fraction of previous work-time. The term, information economy, has been used to describe the integration of communication and data technology into information technology using the Internet as the communication method. Global corporations can only work through information technology, and the only way technology can work is through information systems which are readily available, flexible to changing environments, regularly monitored, and represent the “real world”. Distributed systems technology allows corporations to create the information systems which can be adapted for the needs of 21st century business. It would be difficult to find any large computer-based system today without some type of distributed system. Most information systems distribute processing over several processors. Worldwide, the top priority in the next decade will be updating architectures for implementing or improving distributed computing platforms. The primary…
