The SAP HANA Administrator is responsible for the deployment and monitoring of the SAP HANA Cloud service.
If a migration from an on-premise database to SAP HANA Cloud is required, the administrator should develop skills around the tooling available to automate and ensure a successful migration.
A key responsibility of the administrator is the ensure that SAP HANA Cloud is fully available. This means developing and implementing a fail-over approach. This might include the setting up of redundant backup servers (scale-out).
SAP HANA Cloud provides the SPA HANA Cockpit for monitoring and tracing. Administrators should learn how to use these tools so they can ensure applications that run on SAP HANA Cloud are fully optimized.
With SAP HANA Cloud, the role of the administrator is significantly reduced compared to the on-premise deployment of SAP HANA. This is because the installation of SAP HANA hardware and software is not required. SAP HANA Cloud is deployed using a simple interface and requires no IT skills. But the administrator will certainly be involved with sizing the required cloud tenant and that includes the database memory disk and also if required the data lake. They will also be needed to support the connection of on-premise and other cloud applications to SAP HANA Cloud. But the day to day administration tasks of keeping SAP HANA running, plus backups are the responsibility of SAP or hosting partners and this is the big difference between cloud and on-premise platforms.
