10-Page PDF Document
Prepared for learning & presentation purposes.
Introduction to Spring Boot 3
Spring Boot 3 is the latest version of the Spring framework.
Simplifies application development with auto-configuration.
Focuses on cloud-native and microservice-ready apps.
Supports Jakarta EE 10, improved native image support, and GraalVM.
Why Spring Boot 3?
Faster startup times and reduced memory footprint.
Enhanced observability with Micrometer and tracing.
Upgraded security and authentication mechanisms.
Seamless integration with Kubernetes and Docker.
Microservices Architecture Overview
Architectural style for building distributed applications.
Applications are broken into smaller, independent services.
Each service is responsible for a specific business function.
Promotes scalability, flexibility, and resilience.
Benefits of Microservices
Independent deployment and scaling.
Technology diversity across services.
Improved fault isolation and resilience.
Faster development and release cycles.
Spring Boot & Microservices
Spring Boot makes microservice development easy.
Provides built-in support for REST APIs and messaging.
Works with Spring Cloud for distributed systems.
Supports service discovery, load balancing, and configuration.
Key Components in Microservices

2. API Gateway – Handles routing and authentication.
Service Registry (Eureka) – For service discovery.
Config Server – Centralized configuration management.
Circuit Breaker – Fault tolerance with Resilience4j/Hystrix.
Deployment with Docker & Kubernetes
Spring Boot apps are packaged into Docker containers.
Kubernetes manages deployment, scaling, and networking.
Supports rolling updates and auto-healing.
Enables cloud-native microservice ecosystems.
Challenges in Microservices
Complexity in managing distributed systems.
Network latency and inter-service communication.
Data consistency and transaction management.
Requires strong DevOps and monitoring setup.
Future Trends in Spring Boot & Microservices
Increased adoption of serverless with Spring Boot.
Enhanced use of reactive programming.
AI-driven monitoring and observability.
Integration with edge computing and IoT solutions.
Conclusion
Spring Boot 3 simplifies microservice development.
Provides cloud-native readiness and modern features.
Microservices architecture ensures scalability and resilience.
Together, they power modern enterprise applications.
