Why does CA API Developer Portal 4.2 requires minimum 32 GB RAM to run? 
What requires those 32GB RAM?
What is the least they can configuration to run API Portal 4.2?
The CA API Developer Portal 4.2 in docker based.
Bundled in it is the CA Jarvis (for Analytics and reporting) and this one alone will consume at least 12GB RAM.
Add to it the Portal/Gateway/Internal DB/OAuth/SMTP/Internal Messaging containers and we get more RAM usage.

For production environment it is recommended to have even more, around 64GB RAM and 8 core CPU.

One can install the Portal without the Analytics component and then only 16GB RAM would be needed, as a minimum.
