Monolithic Architecture
Monolithic architecture is a software design pattern where an application is built as a single, unified unit with tightly coupled components, such as the user interface, business logic, and data access layers, all deployed together. It typically runs as a single process on a server, with all code and dependencies packaged into one executable or deployment artifact. This approach contrasts with distributed architectures like microservices, where functionality is split into independent, loosely coupled services.
Developers should consider monolithic architecture for simpler applications with limited scope, where development speed, ease of debugging, and straightforward deployment are priorities, such as in startups or small projects. It is also suitable when the application has low complexity, minimal scaling requirements, and a small team, as it reduces operational overhead and simplifies testing and maintenance compared to distributed systems.
