How to calculate workload for cloud migration

in SQL Performance (MOSC) 5 commentsAnswered

Hi,

We have a production database that is currently running on 24 cpu, but in a shared environment with many other databases.

We're trying to figure out a way to calculate if it that single database can fit into a single pluggable instance in IaaS Azure running oracle 19c with only 2cpu's allocated.

current calculations using DB_BUSY/(DB BUSY+IDLE TIME) over a 7 day period on prem comes up to ~20%.

Would it be accurate to say that we should expect the same ~20% increase onto our Azure Cloud platform as well?

Or am I missing something and there's more things to consider.
