About Object Storage mode replication
If you want to migrate your data center assets to AWS, you have an option to choose between Object Storage mode replication and Direct mode replication. To enable the Object Storage mode replication, you need to deploy a Data Gateway in AWS environment.
See About Data Gateway.
The following are some of the advantages of using the Object Storage mode replication in Resiliency Platform:
Automatically scales according to the requirements of the user by utilizing the AWS services to achieve scalability.
Facilitates resiliency for the Replication Gateway. Since the data keeps getting replicated and stored in S3 bucket, failure of Replication Gateway on the target data center does not hamper the replication.
In case where the Replication Gateway at target data center goes down, data synchronization is performed after the Gateway is restored back or replaced. If the Replication Gateway at the source data center goes down before the synchronization gets completed, you may loose some of the data if you are using the Direct mode of Replication. But if you are using the Object Storage mode replication, then the data can be pulled from S3 bucket and you do not loose any data.
