Abstract: In a computer-implemented method for providing obfuscated data to users, first, a user request to access data is received; then, an authorization level associated with the request received is identified. Next, obfuscated data is accessed in a protected enclave, which data corresponds to the request received. The data accessed has been obfuscated with an obfuscation algorithm that yields a level of obfuscation compatible with the authorization level identified. Finally, the obfuscated data accessed is provided to the user, from the protected enclave. Related systems and computer program products are also disclosed.

Abstract: A computer-implemented method includes managing function calls between a plurality of nodes and a super node of a rack system having a distributed operating system (OS). The OS includes a plurality of functions divided into first class and a second class, and each of the plurality of nodes excludes functions in the second class. Managing the function calls includes detecting a call to a first function on a first node of the plurality of nodes. It is determined that the first function belongs to the second class of functions and is not available on the first node. The call to the first function is routed to the super node, responsive to determining that the first function belongs to the second class, where the super node includes code for the functions in the second class.

Abstract: A computer-implemented method includes managing function calls between a plurality of nodes (120) and a super node (130) of a rack system (100) having a distributed operating system (OS). The OS includes a plurality of functions divided into first class (160) and a second class (165), and each of the plurality of nodes (120) excludes functions in the second class (165). Managing the function calls includes detecting a call to a first function on a first node of the plurality of nodes (120). It is determined that the first function belongs to the second class (165) of functions and is not available on the first node. The call to the first function is routed to the super node (130), responsive to determining that the first function belongs to the second class (165), where the super node (130) includes code for the functions in the second class (165).
