# 🪁 Monolith Architecture Style > In **Monolith Architecture**, the entire application is built as a single, tightly coupled unit. All components (e.g., Api, business logic, and data access) are part of the same codebase and deployed together. # Table of Contents - [Key Features](#key-features) - [When to Use](#when-to-use) - [Challenges](#challenges) ## Key Features 1. **Single Codebase**: All components (UI, business logic, data access) are part of one project. 2. **Tight Coupling**: Components are highly dependent on each other, making changes riskier. 3. **Simple Deployment**: The entire application is deployed as a single unit. 4. **Centralized Database**: Typically uses a single database for all data storage and access. ## When to Use 1. **Small to Medium Projects**: Ideal for applications with limited complexity and scope. 2. **Rapid Development**: Suitable for projects requiring quick development and deployment. 3. **Small Teams**: Works well for small teams with limited resources. 4. **Low Scalability Needs**: Best for applications with predictable and low traffic. ## Challenges - Harder to maintain as the codebase grows. - Limited scalability (scaling requires scaling the entire application). - Difficult to adopt new technologies incrementally.
