Reflectoring: Reactive Architecture with Spring Boot

Based on asynchronous event processing, message-driven data streams, and non-blocking I/O reactive programming is a popular paradigm for developing web and cloud applications, particularly large-scale and distributed ones using a microservices architecture.

Instead of relying on a third-party service, OpenCost allows you to run your own cost monitoring service in your Kubernetes cluster, which might be a useful alternative, especially for enterprise environments where Kubernetes experience and DevOps resources are often readily available.
