How do different server architectures, such as microservices and monolithic architectures, impact server performance, scalability, and maintenance?

Microservices architecture divides an application into smaller, independent services, which can improve scalability and make maintenance easier by allowing teams to update or scale individual services without affecting the entire system. However, it can introduce complexity in terms of deployment, inter-service communication, and data consistency. Monolithic architectures, where all components are interconnected and deployed as a single unit, might be simpler to develop initially but can become difficult to scale and maintain as the application grows, often leading to performance bottlenecks.
