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. Note. The amount of time it takes to create a snapshot varies with the size your databases. There is latency involved while replicating data from source database region to a read replica in another region. C. Create another RDS for MySQL read replica in the secondary. It provides asynchronous copying of objects across buckets in different regions. In case of a regional disruption, you can promote the replica to be the new master and keep your business in operation. Herein, we are looking into a solution of RDS master-master replication.

Cross region replication helps to quickly recover from AWS region wide failures. RDS Multi-AZ Oracle and MSSQL are built to provide high availability within the region, but neither provides the ability to replicate across regions. Cross-Region Replication. B. Migrate the database to Amazon Aurora with cross-Region replicas. Scale Out Globally – If your application has a user base that is spread out all over the planet, you can use Cross Region Read Replicas to serve read queries from an AWS region that is close to the user. Basic tier servers only support same-region replication. For instance, you can schedule events to trigger Lambda functions to create snapshots of your source RDS SQL Server and then copy these to a target DR Region. All data transfers between regions are encrypted using public key encryption. To automate this DR plan, you can use a few AWS tools, such as AWS Lambda and Amazon CloudWatch Events. It's free to sign up and bid on jobs. The target is kept inside the private subnets as it is the best practice to do so. You can now create up to five in-region and cross-region replicas per source with a single API call or a couple of clicks in the AWS Management Console. A. Two Aurora MySQL DB clusters in the same region, by using MySQL binary log (binlog) replication. Cross-region replication allows a live replica to be created in one region, from a master in a different region. Using the cross region snapshot feature, we already transfer hundreds of GB of data from our primary US-East region to the EU-West every week.

To make sure that your cross-Region DR strategy works, you need to test it out regularly. 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 RTO of this DR strategy depends on how quickly to restore a DB instance from the copied snapshot. It is important to note that RPO & RTO comes with a cost, including the snapshots data storage costs as well as data transfer. © 2021, Amazon Web Services, Inc. or its affiliates. © 2020, Amazon Web Services, Inc. or its affiliates.

Instead, you must specify a KMS key valid in the destination AWS region. If you have a very small RPO that requires more frequent DB snapshots, you need to consider a different DR strategy, such as cross-region continuous replication. I recommend appropriate parameter values and metrics to monitor. All database queries (black lines) are directed to in-region or cross-region read replicas, as appropriate: Creating Cross-Region Read Replicas The cross-region replicas are very easy to create. This feature builds upon our existing support for read replicas that reside within the same region as the source database instance. Before you proceed, replicate the RDS and EC2 security groups we created in the Sydney region in the Singapore region. Dilip Kola.
