Coupling leads to fragility
Fragility leads to legacy
Legacy leads to suffering

Hexagonal Architecture in Practice, Live Coding That Will Make Your Applications More Sustainable
By Julien Topçu
Hexagonal Architecture in Practice, Live Coding That Will Make Your Applications More Sustainable
There always comes a point where software becomes so complex and old that it becomes unmaintainable. Updating the technical stack without breaking everything becomes impossible, implementing new features takes longer, and the technical debt is so overwhelming that refactoring becomes exorbitant. What if we told you that all of this is more of a practice problem than a software aging problem? Come and discover through hands-on experience in this 100% live coding session how Hexagonal Architecture can tackle software complexity, making it possible for you to be adaptable and sustainable while helping you manage your technical debt more effectively.
