Spring Boot is a framework that simplifies the development and deployment of microservices, enabling developers to focus on innovation rather than infrastructure. An example application demonstrates these principles by using an API gateway to return processed weather data, sourced from a private weather resource server within a microservice network. The system utilizes a Eureka discovery server for decoupling service providers from clients and enabling client-side load balancing. Feature flags, managed by Split by Harness, allow for dynamic application behavior, facilitating controlled rollouts and real-time adjustments without redeploying code. The application also incorporates HTTP Basic authentication with Spring Security 5, and Split's event logging to track API usage, showcasing the integration of various tools to build a scalable and flexible microservices architecture.
