Monolithic Systems
Monolithic systems are software architectures where all components of an application are tightly integrated into a single, indivisible unit. This includes the user interface, business logic, and data access layers, all deployed together as one executable or process. While simple to develop and deploy initially, monolithic systems can become difficult to scale and maintain as they grow in complexity.
Developers should understand monolithic systems when working on small to medium-sized projects where simplicity and rapid development are priorities, such as prototypes, internal tools, or applications with predictable, low-traffic loads. They are also relevant for legacy systems maintenance, as many older enterprise applications were built using this architecture, requiring knowledge for updates and troubleshooting.
