Thomas is a Software Architect specialized in building highly-scalable, resilient, and secure enterprise applications. He develops software solutions at Systematic, Denmark, where he’s been working on modernizing platforms and applications for the cloud-native world, focusing on developer experience and security. Thomas likes contributing to open-source projects like Spring Security and Spring Cloud. He’s the author of “Cloud Native Spring in Action - With Spring Boot and Kubernetes”, published by Manning, where some of his main interests converged, such as Kubernetes, Buildpacks, Knative, and other cloud-native technologies.
Kubernetes is now a standard to deploy and manage containerized applications. How do functions fit into the cloud-native space in 2022? What does it take to write a function in Java or any other language and get it up and running in a Kubernetes cluster?
We’ll show with practical examples and a live demo how developers can focus on the business logic while the platform takes care of supporting event-driven and serverless workloads in a polyglot environment.
To demonstrate how all these tools can work together, we will show how Knative `func` combines them and provide developers with a Dockerfile-free and Kubernetes YAML-free experience.
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.
