Abstract: A distributed database management system includes a centralized management module for managing resources within a customer network. The management module software, e.g., vCenter, or a health state plugin of the management module, accesses health state information from distributed database nodes within the customer network. The health state information may be or may include a simple signal, analogous to a heartbeat signal, that each functional node generates periodically and sends to the management module. The nodes may include a primary node to maintain a database and one or more secondary nodes to replicate the database. The primary and secondary nodes may be nodes within an edge node cluster of the customer network. The edge node cluster may be implemented within an infrastructure appliance, e.g., VxRail. The management module shares the health state information with the nodes and controls, based on the health state information, the designation of a primary node and secondary nodes.

Abstract: A secured virtual container is enabled to securely store personal data corresponding to a user, where such data is inaccessible to processes running outside the secured virtual container. The secured virtual container may also include an execution environment for a machine learning model where the model is securely stored and inaccessible. Personal data may be feature engineered and provided to the machine learning model for training purposes and/or to generate inference values corresponding to the user data. Inference values may thereafter be relayed by a broker application from the secured virtual container to applications external to the container. Applications may perform hyper-personalization operations based at least in part on received inference values. The broker application may enable external applications to subscribe to notifications regarding availability of inference values. The broker may also provide inference values in response to a query.
