As part of our sustainability efforts, I would like to understand how to measure and reduce the carbon footprint of application built on Pega CS (AWS Cloud offered by Pega).

Could you please advise:

1. What metrics (e.g. CPU, storage, transactions) are available to approximate application-level energy / carbon use?
2. What best practices do you recommend to optimize applications for lower resource consumption?
3. Is there or will there be integration with AWS carbon reporting tools?
