Decomposition of monoliths into multi-account provider network structures

Abstract

Remapping mainframe functional components from a mainframe computing environment onto a network of distinct but communicating accounts of a provider network. The mainframe computer (or network of such computers) is analyzed hierarchically through one or more of physical separation between logical partitions (LPARs), LPARs within the mainframe computer(s), separation of batch and transactional workloads, separation of batch and transactional accounts, or security of the mainframe architecture. Mainframe application artifacts obtained through the analyzing are used to generate a graph model representing relationships among the mainframe application artifacts. The graph model includes nodes representing the mainframe application artifacts and edges connecting pairs of the mainframe application artifacts, where the edges represent use relationships between the pairs of mainframe application artifacts. The nodes are then clustered, where the clusters represent sets of mainframe artifacts having high density of use relationships, and the clusters correspond to the distinct accounts in the provider network.
