What is Spring Boot? How does it simplify the development of Java applications? Answer: Spring Boot is a framework that simplifies the development of Java-based applications by providing pre-configured setups and conventions. It eliminates the need for manual configuration and boilerplate code, allowing developers to quickly set up and deploy production-ready applications with minimal effort. Can you explain the concept of microservices architecture? How does it differ from monolithic architecture? Answer: Microservices architecture is an architectural style that structures an application as a collection of loosely coupled services, each responsible for performing a specific business function. These services are independently deployable and scalable. In contrast, monolithic architecture is a traditional approach where all components of the application are tightly integrated into a single codebase, making it difficult to scale and maintain.
