AWS RDS MySQL Cross-region replication


AWS RDS MySQL Cross-region replication

will be helpful for those in need I highly recommend switching from RDS MySQL to RDS Aurora, which is MySQL compatible. You won't have to change anything in your code, the database will still appear to be MySQL to any apps that connect to it. Among the many advantages Aurora has over MySQL is that it supports cross-region replication.

it should still fix some issue It appears the Cross-Region Replication in Amazon S3 cannot be chained. Therefore, it cannot be used to replicate from Bucket A to Bucket B to Bucket C.
An alternative would be to use the AWS Command-Line Interface (CLI) to synchronise between buckets, eg:
code :
aws s3 sync s3://bucket1 s3://bucket2
aws s3 sync s3://bucket1 s3://bucket3

I wish this help you You are right. As is, the setup won't work because KMS keys can't be shared across regions.
Let's say you are replicating data from region R1 to R2, which have KMS keys K1 and K2 respectively. I can suggest the following alternatives:

This might help you There is not such thing as multi-location GAE apps (at least not yet). The app's unique location can be selected when the app is created and cannot be changed. See App Engine - How to create project in region us-central and gae app moving to eu-datacenter or re-opening

help you fix your problem The issue with bi-directional replication always boils down to "who has the correct version" of data. It's not so hard right now when there is only one source of data but what about when there are two? If one process writes to one region and another writes the same thing to another, what adjudicates the conflict?
This is why you don't see documentation about bi-directional replication - it's hard to solve in a generic way. I would look at something like s3 sync or a custom script to get the buckets back in sync.

wish of those help There might be a timing delay between bucket replication -- this is why replicated buckets require Versioning to be turned on, so that delayed propagations will still have access to the source data.
Also, any objects in the source bucket prior to turning on replication will not be replicated to the target.
