Abstract

Application splitting for network edge computing including identifying an application split point; identifying a split type for the application split point; splitting the application into subcomponents in accordance with the split type; and moving a subcomponent to an edge network. Identifying an application split point may include identifying a class of the application that calls an EJB. Identifying an application split point may include identifying a class of the application that updates an enterprise database. Identifying an application split point may include identifying a class of the application that calls a JCA function. Identifying a split type for the application split point may include identifying a silo split type for the application split point. Identifying a split type for the application split point may include identifying an EJB split type for the application split point.
