Do you want to use a microservices architecture? Are you looking for a solution to manage access to single services from clients? How can you ensure resilience and security for your entire system? Spring Cloud Gateway is a project based on Reactor, Spring WebFlux, and Spring Boot which provides an effective way to route traffic to your APIs and address cross-cutting concerns.
In this session, I’ll show you how to configure an API gateway to route traffic to your microservices architecture and implement solutions to improve the resilience of your system with patterns like circuit breakers, retries, fallbacks, and rate limiters using Spring Cloud Circuit Breaker and Resilience4J. Since the gateway is the entry point of your system, it’s also an excellent candidate to implement security concerns like user authentication. I’ll show you how to do that with Spring Security, OAuth2, and OpenID Connect, relying on Spring Redis Reactive to manage sessions. Finally, I’ll show you how to improve the observability of your system using Spring Boot Actuator and Spring Cloud Sleuth and relying on the Grafana stack.

What a presentation @Thomas. Big Kudos. I am newbie to Spring Boot and went through couple of presentations. My investigation to use Spring Cloud Gateway vs. Nginx ended after this presentation.

Excellent video, thanks for sharing! I have a question, if we had multiple instances of SCG balanced by an apache proxy, how we would prevent session cookie loss? I have used sticky session but I don't know if this is the way to go with Spring, and also I want to keep my app stateless. How can I address this issue?

[@user-us9rl1ex2q]

Can we have both Retry and Circuit Breaker configuration?? On applying CircuitBreaker, Retry is not working.

Thomas what he do in spring
