Hi,

This very detailled guidance has exactly been written to compare those alternatives with differences, pros & cons, etc. : https://docs.aws.amazon.com/pdfs/prescriptive-guidance/latest/aurora-replication-options/aurora-replication-options.pdf

That should really help you in choosing the best one for your use case.

Best,

Didier

Thanks Didier for the document.

The comparison in document (in page 5) has all similarities, except replication lag of few seconds.

Still I didn't get exact difference between Aurora Global database and cross-region read replicas.
