Architecure Evolution & DevOpts

Conway's Law states that " organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations. " This principle, introduced by Melvin Conway in 1967, has profound implications for software development, particularly in the era of microservices, DevOps, and cloud-native architectures. In this article, I will explore how organizational structures influence software design, how companies can use this law to their advantage, and best practices for aligning teams with software architecture for maximum efficiency.

In this article, I will explore how to create a complete application that implements a CRUD API using Spring Boot 3. I will perform Create, Read, Update, and Delete operations on a database, implement authentication and authorization with JSON Web Token (JWT), and develop a REST API for managing orders in an e-commerce system. Finally, I will test the API using JUnit.
