In this blog, I will explore how to enable cross region replication in different AWS regions. One is Tokyo and one is in Ohio region. Replication copies recently created objects & object updates from a source bucket to a destination bucket. Replication is the automated, nonsynchronous copying of objects crosses buckets in the different or same AWS Regions.
