Modernizing Code Older than You Are: One Student Takes a COBOL Bank App to Hybrid Cloud
summary
A student extracts a 60‑file COBOL banking monolith into four services (sign‑on, account balance, update contact, loan calculator), deploys them to AWS Enterprise Server regions, and wires modern UIs: Android, PHP/HTML/CSS web pages and a Flask app. Tools used include Micro Focus Enterprise Analyzer, Enterprise Developer and Kickstart; the loan calculator becomes a standalone DLL called from Python via ctypes calling COBOL DLL. All demos run and documentation + code live on GitHub.
