This course explores real-life scenarios of digital solution implementations in various industry settings. Our case studies examine how today's companies build large-scale software platforms and transform their business models using modern technologies such as the cloud, internet-of-things (IoT), machine learning, blockchain, and robotic automation. Architecture is the art of designing complex structures. Enterprise architecture (EA) is the art of designing software solutions. It is an enterprise architect's job to translate a company's goal into a business capability, design a technology solution, and fit it into the operations of a working organization. Digital technologies, with their high potential, intricate complexity, and disruptive nature, demand highest competency in enterprise architecture. Any business software application designed today becomes part of an enterprise ecosystem with architectural demands of interoperability, extensibility, scalability, security, and data integrity. We read case papers and discuss them in class.
