A developer on a new app team pings you.
"๐๐ฆ๐บ, ๐ค๐ข๐ฏ ๐ธ๐ฆ ๐จ๐ฆ๐ต ๐ข๐ฏ ๐๐๐ ๐ง๐ฐ๐ณ ๐ต๐ฉ๐ข๐ต?"
You know exactly which service program holds the logic. You've maintained it for years. It's solid, it's fast, it's never failed.
You just don't have an endpoint to give them.
So they build a workaround. A nightly export. A flat file nobody trusts. A "temporary" bridge that's still running three years later.
Your IBM i isn't the problem. The missing front door is.
Here's the 3-step pattern we use to fix that:
๐ญ. ๐๐ถ๐ป๐ฑ ๐๐ต๐ฒ ๐๐ฒ๐ฟ๐๐ถ๐ฐ๐ฒ ๐ฝ๐ฟ๐ผ๐ด๐ฟ๐ฎ๐บ.
Not the whole application โ just the callable logic that actually does the work.
๐ฎ. ๐ช๐ฟ๐ฎ๐ฝ ๐ถ๐.
A REST-enabled wrapper in ILE RPG, or a lightweight Node.js bridge sitting in front of it.
๐ฏ. ๐๐
๐ฝ๐ผ๐๐ฒ ๐ถ๐.
Push it through an API gateway with auth and rate limiting โ and it's live.
That's it. Your decades-old business logic is now something a modern app can call directly.
No rewrite. No rip-and-replace. Just a door where there wasn't one before.
Where does your team usually get stuck โ Step 1, 2, or 3? ๐
