Abstract: A method for processing a software application workflow using a workflow engine includes receiving a workflow configuration defining the workflow including a plurality of nodes and a plurality of connections between the nodes, each of the nodes associated with a corresponding software processing task. The method includes determining a first set of nodes of the plurality of nodes to be executed based on the workflow configuration and the plurality of connections. The method includes causing execution of the software processing tasks associated with the first set of nodes, resulting in an execution result. The method includes determining a second set of nodes of the plurality of nodes to be executed based on the workflow configuration, the plurality of connections, and the execution result. The method includes causing execution in parallel of the tasks associated with the second set of nodes.

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.
