Event-Driven Programming

In past chapters, you have learned OOP principles and approaches to easily handle ambiguities and issues with reusable, extendible, and easily usable software. On the other hand, to deploy software applications over the Internet, you use client-server or distributed applications architecture. These software applications’ major challenges are handling service failures, changing existing services, introducing new services, and replicating existing services to handle scalability issues. However, software must be flexible for any enhancements and extensions to handle these challenges. Moreover, novel software such as IoT, smart applications, gaming software, and distributed applications must be designed and developed to meet scalability, reliability, and flexibility expectations.
