For effective resource management in SAP HANA, what should be done for each tenant in a multi-tenant system?

For effective resource management in SAP HANA, providing dedicated operating system (OS) users for each tenant in a multi-tenant system is essential. This approach allows for the isolation of resources and enhances security, as each tenant operates under its own user account with specific permissions. By doing this, administrators can manage and control access to system resources efficiently, ensuring that no single tenant can affect the performance of others.

Dedicated OS users facilitate better monitoring and troubleshooting, as all actions and resource usage can be traced back to a specific tenant. This level of granularity is particularly important in multi-tenant environments, where different business units or clients might have varying needs and performance requirements.

In contrast, assigning all tenants to the same resource group or sharing network resources could lead to contention and performance issues, where one tenant's high usage could negatively impact others. Similarly, limiting memory access for each tenant could hamper their ability to function optimally, reducing the overall effectiveness of the system. Therefore, providing dedicated OS users is a best practice in deploying multi-tenant systems within SAP HANA.
