Here is an introduction to Spring Cloud Gateway for VMware Tanzu, including key features and specialized information depending on whether you are an operator and app developer.
About Spring Cloud Gateway for VMware Tanzu
The open-source Spring Cloud Gateway project is an API gateway built on Spring ecosystem projects, including Spring 5, Spring Boot 2, and Project Reactor. It provides an effective solution for routing diverse client requests to APIs and addresses cross-cutting concerns such as security, monitoring and metrics, and resiliency. For more information about the open-source project, see the documentation.
Spring Cloud Gateway for VMware Tanzu automates the deployment of an API gateway service by adding it to the Marketplace, so that developers can use Apps Manager or the Cloud Foundry Command Line Interface (cf CLI) tool to deploy their own API gateway based on Spring Cloud Gateway. Binding an app to this new Gateway service instance will provide service instance information to the app's environment.

- Addition of a Spring Cloud Gateway app to the Marketplace as a managed service
- Integration of Spring Cloud Gateway service with the VMware Tanzu Application Service container network security model, including Mutual TLS support
