Aravind M you’re correct, checking the documentation from AWS it indicates that changing storage size won’t require downtime while changing instance class will result in down time
what is the performance and availability impact when CMK is rotated? assuming there's a few million rows in the database, it means millions of the data keys need to be re-encrypted, how much time this process would take? when key rotation happens, what happens to the automated backups?
loved the deep dive for RDS, good and clear understanding of what RDS is and how to use it.
15:50 He says there will be downtime when you scale storage but i think he means there will be downtime when you scale cpu/memory

Yes. Downtime occurs only when you scale verticaly
In fact, also, when you increase storage or take backups you'll see a degradation in your storage performance.
that is precisely he was mentioning backups need to taken from the secondary.

what is the default RAID configuration used by RDS?
