Application modernization

A computer system comprising:

• a number of processor units, wherein the number of processor units executes program instructions to:
• analyze each application in applications in isolation from other applications to identify issues in code for the applications and a number of common code components;
• create a directed graph structure using the issues identified in the applications and the number of common code components, wherein the directed graph structure includes relationships between the applications, the number of common code components, and the issues identified;
• determine a common code component modernization cost for the number of common code components using the directed graph structure;
• and
• determine an application modernization cost for a set of the applications using the directed graph structure, wherein the application modernization cost for the set of the applications takes into account the common code component cost for modernizing the number of common code components a single time.

A computer program product for modernizing applications, the computer program product comprising:

• a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer system to cause the computer system to perform a method of:
• analyzing, by a number of processor units, each application in the applications in isolation from other applications to identify issues in code for the applications and a number of common code components;
• creating, by the number of processor units, a directed graph structure using the issues identified in the applications and the number of common code components, wherein the directed graph structure includes relationships between the applications, the number of common code components, and the issues identified;
• determining, by the number of processor units, a common code component modernization cost for the number of common code components using the directed graph structure;
• and
• determining, by the number of processor units, an application modernization cost for a set of the applications using the directed graph structure, wherein the application modernization cost for the set of the applications takes into account the common code component cost for modernizing the number of common code components a single time.
