Overview

In a monolithic architecture, all components of the software—such as the user interface, business logic, and data access layer—are tightly coupled and managed within a single codebase and deployment unit.

Key Characteristics

  • Single Codebase: All functions are managed in one place.
  • Unified Deployment: The entire application must be redeployed for any change.
  • Shared Resources: Components share the same memory space and database.

Pros and Cons

  • Pros: Simpler to develop, test, and deploy initially; better performance due to lack of network latency between components.
  • Cons: Difficult to scale individual components; slow deployment cycles; high risk as a single bug can bring down the entire system.
