Message server for ABAP Netweaver

SAP Traditional Applications Classic three-tier architecture:

The Message Server, which acts as a Load Balancer, is not represented in the figure. Message servers, however, play an important role in our daily work with SAP GUIs.

For example, Jerry does the system AG3 for CRM development, and the message server maintenance is as follows:

Using the transaction code SMLG, AG3 is found to consist of three different application servers, numbered 54, 55 and 56.

When a user logs in using the SAP GUI, the message server automatically returns the application server instance with the least current load to the user for login. All application servers participating in the Load Balancer scenario also periodically notify the Message Server of their load.

CloudFoundry Application Router

In SAP Cloud Platform CloudFoundry environments, the Application Router serves as the entry point for all application access.

The illustrations in Figures 1 - 8 above depict how Web applications deployed on SAP Cloud Platform CloudFoundry environments access services on On-Premise systems through Cloud Connectors.

1. The App Router acts as an entry point for user access.

2. User access requests are redirected to XSUAA. XSUAA requires users to log in. After the user completes the login operation, a JSON Web Token(abbreviated as JWT1) is created, sent to the App Router, and cached in the App Router.

3. The App Router forwards the request to the Web app along with the JSON Web Token generated in step 2.

4a. The Web app again requests a JSON Web Token(JWT2) from XSUAA to access the destination instance.

4b. The Web application requests a third JSON Web Token(JWT3) from XSUAA in parallel for access to the connectivity instance.

5. The Web app uses JWT2 to get the destination configuration.

6. The Web forwards the request and JWT3 to the connectivity instance.

7. SAP Cloud Platform Connectivity forwards the request to Cloud Connector via Secure Tunnel.

8. Cloud Connector sends the request to the On-Premise system.
