This longer article will attempt to summarize many core strategies and tactics used for migrating legacy applications from on-prem to the cloud.
“Traditional Production Applications” (TPA) are those like:
1) x86-based client/server architectures, especially those utilizing older versions of Linux or Windows Servers not supported by cloud vendors like Azure.
2) Applications based on “mid-range” systems like IBM Power AIX (running UNIX).
3) Applications based on mid-range systems like IBM Power IBMi, AS/400.

This will be an ongoing edit. Like Fashion, “It will never be finished.” It will be refined over time.
