What is Spring Boot Used for?

Spring Boot is a framework used for building Java-based applications, particularly web applications and microservices. It is built on top of the Spring Framework and provides a streamlined way to develop standalone, production-ready applications with minimal configuration.

Key Uses of Spring Boot:

1. Microservices Development – Simplifies the creation of independent, deployable microservices.
2. REST API Development – Makes it easy to develop RESTful web services with built-in support for JSON and XML.
3. Web Applications – Supports the development of full-stack web applications using Spring MVC.
4. Enterprise Applications – Suitable for large-scale applications with complex business logic.
5. Database Connectivity – Provides seamless integration with databases using Spring Data JPA, Hibernate, and JDBC.
6. Security – Offers built-in security features via Spring Security for authentication and authorization.
7. Cloud and DevOps – Works well with cloud platforms (AWS, Azure, Google Cloud) and containerization tools like Docker and Kubernetes.
8. Batch Processing – Supports batch processing with Spring Batch for handling large data sets efficiently.
9. Messaging and Event-Driven Applications – Integrates with Kafka, RabbitMQ, and ActiveMQ for asynchronous processing.

Why Use Spring Boot?

✅ Reduces Boilerplate Code – Eliminates the need for extensive configuration.
✅ Embedded Servers – Comes with built-in servers like Tomcat, Jetty, or Undertow.
✅ Auto-Configuration – Automatically configures components based on dependencies.
✅ Spring Ecosystem Integration – Works seamlessly with Spring Cloud, Spring Security, Spring Data, etc.
✅ Production-Ready Features – Provides metrics, health checks, and logging via Spring Boot Actuator.
