Take it to the Cloud: SAP HANA Cloud Connector

SAP-hana-cloud-connector blog-post-image1 JR So you made an SAP App in HANA Cloud and you successfully registered from the device. Now we can get to the part this has all been about: the backend systems. Before we CRUD on-premise data, we must tell HANA Cloud how to connect to the on-premise systems. This is achieved through the HANA Cloud Connector.The HANA Cloud Connector (HCC) is a piece of software that allows you to securely connect and register on-premise systems with HANA Cloud. SAP supplies a succinct tutorial for configuring the HCC. During the HCC configuration, note your Virtual Hostname and Port. The values can be set to any value you like, as they are only linked to your SAP HANA Cloud account. They are the unique identifiers for your on-premise systems. Ensure you have added at minimum a “/” resource path so all calls will be directed to the proper source (unless explicitly unwanted). Once the HCC has been configured, we will configure the app in the HANA Cloud Platform Mobile Services Cockpit. This is the cockpit we used in Part 1 to setup the app. Once in the cockpit, select the app you are working on, click Configure, and choose the tab labeled Back-End. Enter the Virtual Hostname followed by port and endpoint you wish to hit.

Ping your endpoint from the Cockpit to ensure the connection was established. If the ping is successful, you are ready to move on to the fourth part, CRUD oData (which we’ll be covering in a future blog post).
