Monolithic architecture combines all components into a single codebase and deployment unit, while microservices architecture breaks an application into small, independent services that communicate through APIs.

Monolithic architecture is generally easier for beginners because it has one codebase, simpler development workflows, and a straightforward deployment process.

No. Microservices offer flexibility and scalability but come with operational complexity. Monolithic architecture is often better for small teams, MVPs, and early-stage projects.

Choose monolithic when you're building an MVP, working with a small team, or developing an application with limited features that doesn’t require independent scaling.

Microservices work best for large, complex, and rapidly growing applications that need independent scaling, faster deployments, and greater reliability.

Microservices offer better fault isolation. If one service fails, the rest of the system can usually continue running. In monolithic architecture, one failure can impact the entire application.
