I can't find an answer for this, what are the key differences between ATP & Apex workload for autonomous database.
I find out that , in the cost estimator with exact same ecpu & storage, ATP costs 3x more tham Apex workload. Why ecpu is way expensive. Hourly prices around for atp - 0.3$ / hour , apex - 0.08$/h . Storage price are the same but i didn't get why ecpu is that much differs.
My usage → I'm using oracle for apex based web applications with some PL/SQL backend. Also i'm releasing my apps from my dev database to prod database with apex apps & plsql packages , triggers etc.
In that condition which one should i choose for future development.
