Abstract: Methods and apparatuses are described for decentralized authorization of user access requests in a distributed service architecture. A gateway node receives a user access request from a remote computing device. The gateway generates a signed and encrypted access token based upon the user access request using an authorization service node and a key management service node. The gateway transmits the access token, the user access request, and a security certificate received from the authorization service to a security proxy node of a microservice container. The security proxy validates the certificate and the access token. The security proxy decrypts the access token using a public key from the certificate, and determines user authorization to access a service endpoint node based upon the decrypted token. The security proxy transmits the user access request to the service endpoint, which provides the remote device with access to services based upon the user access request.

Abstract: A processor identifies that at least one value of a primary shortage metric triggers an exception to a rule. The processor retrieves a list of items that have a non-zero value for the primary shortage metric and retrieves at least one secondary shortage metric value for each item in the list of items. The processor then generates report data for a report that includes at least one item in the list of items and the values of the first and second shortage metrics for the item.
