Chapter 1. Adding and accessing OpenShift API Management Red Hat OpenShift API Management is a managed API traffic control and program management service based on the Red Hat 3scale API Management platform. It includes an implementation of Red Hat Single Sign-On. You can add OpenShift API Management to an existing OpenShift Dedicated or ROSA cluster in the OpenShift Cluster Manager. 1.1. Introduction to Red Hat OpenShift API Management Application Programming Interface (API) management refers to the processes of distributing, controlling, and analyzing the APIs that connect applications and data across cloud environments. You can streamline API management in a unified service by using Red Hat OpenShift API Management. Red Hat OpenShift API Management is a managed service that is based on the Red Hat 3scale API Management platform and is available as an add-on in Red Hat OpenShift Dedicated. With OpenShift API Management you can secure, manage, and monitor APIs at every stage of the development lifecycle. Use OpenShift API Management to manage users, oversee the API gateway, and configure APIs for increased accessibility. You can deploy Red Hat OpenShift API Management on Amazon Web Services (AWS) versions of OpenShift Dedicated and the Red Hat OpenShift Service on AWS. OpenShift API Management includes capabilities of the following Red Hat products: Red Hat Single Sign-On provides single sign-on (SSO) authentication to secure web applications. Red Hat 3scale API Management is a management platform that allows users to share, secure, distribute, control, and monetize APIs. After setting up authentication and user accounts, OpenShift API Management developers, also referred to as API providers, can configure, and publish 3scale API products. The following actions are important to understand before you use Red Hat OpenShift API Management: Configuring your identity provider to provision OpenShift Dedicated and secure APIs. Note The email address and the User Principal Name (UPN) must be paired for Red Hat Single Sign-On configured with OpenID to work between OpenShift and Red Hat 3scale API Management. The UPN and email must match or the OpenID UPN and email fields must map to the username field and email field of the customer in the OpenShift IDP configuration.
