Abstract: A method of tenant user management in cloud database operation can be implemented. The method can receive an original job request from a user for a database service, wherein the original job request can include a login credential of the user. The method can authenticate the login credential of the user by a scheduler, verify the user has privileges for the original job request by the scheduler, create a modified job request from the original job request by the scheduler based on a predefined role corresponding to the privileges of the user, send the modified job request from the scheduler to a database service platform, and allocate an instance of database service to the user in response to the modified job request.

Abstract: Various examples are directed to systems and methods for operating a database management system (DBMS) in a cloud environment. An assembly worker executing at a first computing device may provide a first database protocol message generated by a process code executing at the first computing device. A translation engine executed at the cloud environment may translate the first database protocol message from a first format to a second format associated with a DBMS instance executing at the cloud environment to generate a translated first database protocol message. The translation engine may cause the translated first database protocol message to be provided to the DBMS instance and may receive, from the DBMS instance, a first reply corresponding to the translated first database protocol message. The first reply may be sent to the process code.

Abstract: Methods, systems, and computer-readable storage media for receiving, by an operation guard system executed within a cloud platform, session information representative of a session of a user within the cloud platform, the session information including user information and operation information, determining, by the operation guard system, that the user is signed into a technical group for execution of an operation represented in the operation information, and in response, providing, by the operation guard system, a risk score associated with the operation, and determining, by the operation guard system and at least partially based on the risk score, that the operation is a risk-oriented operation based on the risk score, and in response, preventing execution of the operation and transmitting an alert.

Abstract: Methods, systems, and computer-readable storage media for receiving, by a cross-process scheduling engine executed within a cloud platform, work scenario metadata and sensitivity metadata, generating, by the cross-process scheduling engine, a lineage graph representing relationships between one or more of data and processes to be executed for a work scenario represented by the work scenario metadata, defining, by the cross-process scheduling engine, a set of tile segments for the work scenario based on the lineage graph and the sensitivity metadata, dispatching, by the cross-process scheduling engine, a first sub-set of tile segments for execution in a private deployment including one or more private nodes, and dispatching, by the cross-process scheduling engine, a second sub-set of tile segments for execution in a public deployment including one or more public nodes.
