I've been struggling with AWS private keys as I try to keep all of my AWS credentials safe, secure, and organised. Should I be using the same AWS key for multiple EC2 instances or should each instance have its unique private key?
I've been looking around for a best practice regarding this. If you can explain why in addition, I'd appreciate it very much.
I've been leaning towards the practice of giving each instance its unique private key to compartmentalise security.
Thanks in advance!
