Quick Facts

What is Spring Boot?

Spring Boot is a Java backend framework used to build APIs, microservices, data-driven services, and production-ready enterprise applications.

Why Learn Spring Boot?

Spring Boot is valuable because it turns Core Java knowledge into real backend delivery skills used in APIs, enterprise services, and modern microservice programs.

Where is Spring Boot used?

Spring Boot is used in enterprise APIs, internal platforms, customer-facing backend systems, microservices, and Java teams building production-ready backend services.

Interview Preparation
