Spring Boot 4 Application Development

A backend that runs locally is not necessarily a backend that is ready to maintain, secure, test, and deploy.
A successful implementation depends on more than choosing tools. Turning a working backend prototype into a service that is maintainable, testable, secure, and ready for real operating conditions is a different challenge from following a short tutorial.
This hands-on resource explores HTTP endpoints, service layering, persistence, security, integration testing, application configuration, packaging, monitoring, and deployment. It connects these subjects to the work developers actually perform: defining requirements, breaking projects into manageable steps, evaluating design options, testing results, and preparing applications for delivery.
What You'll Explore Inside:

1. Design cohesive service boundaries, request handling, validation, and clear error responses.
2. Examine authentication, authorization, configuration, and secure handling of application data.
3. Understand relational persistence, transactions, migrations, and integration strategies.
4. Compare monolithic and service-based architectures with attention to operational tradeoffs.
5. Plan automated tests, observability, deployment, and troubleshooting procedures.
6. Evaluate performance and reliability concerns before treating a system as production-ready.
