The document discusses the transition from monolithic applications to a more modular architecture using HMVC and microservices. It highlights the problems associated with legacy systems and the benefits of adopting HMVC for better organization, reusability, and maintainability. The author emphasizes the importance of modernizing software architecture and provides insights into implementing ColdBox modules for streamlined development.

Revamp your monolith with Hierarchical MVC at CFSummit 2018
- 1. Hierarchical MVC Transform your Monolith
- 2. WHO AM I? ⢠Luis Majano ⢠Computer Engineer ⢠Born in El Salvador ->Texas ⢠CEO of Ortus Solutions ⢠Sandals -> ESRI -> Ortus @lmajano @ortussolutions
- 3. The Legacy Problem Monolithic Applications HMVC Architecture ColdBox Modules API Demo
- 5. LEGACY PROBLEM ⢠Gives CFML a bad name ⢠Security Issues ⢠Performance Issues ⢠Employee Issues ⢠Development Issues ⢠Finding Developer Issues
- 6. LEGACY PROBLEM â˘>35% No MVC â˘>60% No DI â˘>55% No Testing FuseBox is NOT MVC
- 7. LIKE MY CFML APP? ⢠MVC Framework or spaghetti hell? ⢠OO or cďŹnclude hell? ⢠Automated Tests? Continuous Integration? ⢠Agile/Scrum Methodologies? ⢠Source Control? (Zip ďŹles donât count!) ⢠Continuous Delivery? Container Strategy? ⢠Developer Automation?
- 9. Legacy Fun Comments <!â- Do not remove the following lines or things break â> <!â Dontâ know what this variable does, but donât touch it â-> <!â- Remove at your own risk â-> <!â- I have no idea where this variable is set â>
- 10. âSoftware is always bound to changeâ
- 11. BACK TO THE SCHOOL OF ARCHITECTURE
- 12. 1. COHESION - COUPLING
- 13. 2. MVC ⢠Separates layers of concerns ⢠Helps enforce OO ⢠Specialized team members ⢠butâŚ.. ⢠Layers are still tightly coupled ⢠MVC Monoliths
- 14. 3. N-TIER - MEXICAN CHALUPA ⢠Add more layers for organization ⢠Layers are still tightly coupled ⢠Still monolithic! ⢠Yummy, but hard to eat!
- 15. 4. HMVC
- 16. 4. HMVC ⢠Evolution of MVC ⢠Independent MVCTriads ⢠BeneďŹts ⢠Higher Cohesion ⢠Lower Coupling ⢠Modularization ⢠Better ⢠Organization ⢠Reusability ⢠Extensibility ⢠Testability

"In structured design and data-driven design, a module is a generic term used to describe a named and addressable group of program statementsâ ⨠by Craig Borysowich (ChiefTechnologyTactician) âA software module is a deployable, manageable, natively reusable, composable, unit of software that provides a concise interface to consumers.â ⨠by Kirk Knoernschild
