Explore the nuances of software architecture in this 46-minute conference talk from GOTO London 2016. Delve into the concept that one size does not fit all when it comes to structuring software components. Learn about information hiding, separation of concerns, and the Single Responsibility Principle. Examine indicators of strong and weak cohesion, and understand the forces that drive separation in software design. Investigate common traits of microservices and explore real-world examples of different-sized components, from nano-services to medium-sized structures. Identify and avoid antipatterns such as decoupling illusion, anemic services, and unjustified re-use. Gain insights into effective software architecture practices and discover what truly works in creating scalable, maintainable systems.
