This post discusses how to create a reliable cross-Region DR strategy for Amazon RDS for SQL Server. In case of a regional disruption, you can promote the replica to be the new master and keep your business in operation. Typically, on-premises customers set up synchronous replication for SQL Server in a single data center where they are preventing hardware failure, and they set up either an asynchronous replication or snapshot in a different data center or possibly a different site. The following steps show how to optimize DR strategy, read workload, and healthy source instance while minimizing replication lag. This feature builds upon our existing support for read replicas that reside within the same region as the source database instance. For more information about performance considerations, see Best practices for AWS Database Migration Service. First, you need to understand how DR changes in the AWS cloud. The RTO of this DR strategy depends on how quickly to restore a DB instance from the copied snapshot. Being a managed service, Amazon RDS for SQL Server helps automate time-consuming tasks like patches, backups, high availability, and more. Install MySQL on Amazon EC2 in the secondary Region. Two Aurora MySQL DB clusters in the same region, by using MySQL binary log (binlog) replication. For more information, see Amazon RDS for SQL Server. Cross-region replication allows a live replica to be created in one region, from a master in a different region. You can only replicate from the source bucket to only ONE another bucket. You simply select the desired region (and optional availability zone) in the AWS Management Console: You can also track the status of each of your read replicas using RDS Database Events. Simply create the replica, ensure that it is current, promote it to be a master database instance, and point your application at it. C. Create another RDS for MySQL read replica in the secondary. To make sure that your cross-Region DR strategy works, you need to test it out regularly. I have a db instance in aws region us-east-1 running through terraform code.

When you create an s3 bucket and turn on replication, it replicates from one region to another, by default this is done using SSL. If X wants to copy its objects to Y bucket, then the objects are not copied immediately. The cost of this DR strategy is mainly the storage cost for the snapshots and data transfer cost to copy these snapshots from your primary region to DR region. To learn more about cross-region replication for RDS PostgreSQL, please refer to the RDS documentation. We use Amazon RDS to store mission critical clinical development data and tested many data migration scenarios between Asia and USA with the cross region snapshot feature and found it very simple and cost effective to use and an important step in our business continuity efforts. We now look forward to the Cross Region Read Replica feature, which would make it even easier to replicate our data along with our application stack across multiple regions in AWS. The first snapshot of a DB instance contains the data for the full DB instance. The target is kept inside the private subnets as it is the best practice to do so. Share this item with your network: By It is important to note that RPO & RTO comes with a cost, including the snapshots data storage costs as well as data transfer.
