    Study Notes

    • Ingress is a door to your Kubernetes services that allows external access to the cluster.
    • An Ingress defines a Kubernetes API that allows external reachable URLs with load balancing.
    • An Ingress object sets specific rules for how to route incoming traffic.
    • An Ingress controller is an application that implements an Ingress API.
    • An Ingress is not enough by itself, so the community has been thinking beyond Ingress.
    • A service mesh is a cloud-native dedicated infrastructure layer application that controls service-to-service communication inside the Kubernetes cluster.
    • Like the other Kubernetes services, the service mesh needs an entrance, such as an Ingress, to the services running on top of the service mesh.
    • The Ingress API is simple and stable, but due to the lack of capabilities, vendors and others have created workarounds like extra APIs or annotations.
    • The Gateway API was created to address the issues with the Ingress API and its lack of capabilities.
    • Envoy is a popular edge and service proxy with over twenty thousand stars and almost four thousand forks on GitHub statistics. It's a very active and healthy community project.
    • Envoy incorporates all the learnings from the older versions, including the dynamic configuration based on xDS REST protocols and the ability to load dynamically.
    • Envoy includes filters that perform transformations on requests and responses, and can be chained together to add features like Intrusion Detection System (IDS), compression, rate limiting, and more.
    • With these filters, you can add features like Intrusion Detection System (IDS), compression, rate limiting, and more as layer 7 filters.
    • Envoy also has extensive statistics that can be exposed via Prometheus and Grafana, for example.
    • Tracing services can help you understand the flow of requests and the time spent on each step of the process.
    • Tracing services can be used with Envoy-based service meshes to create very detailed call graphs.
    • This information can be useful for understanding the flow of requests and for optimizing the performance of your services.
