S3 Bucket Cross-Region Replication for GxP EU Annex 11 Compliance
Rule Description
Cross-region replication (CRR) for Amazon S3 buckets is a key strategy to ensure that data is replicated across geographic locations, which can be an important factor for regulatory compliance such as GxP EU Annex 11. GxP regulations encompass Good Practice quality guidelines and regulations for the pharmaceutical and medical device industries. EU Annex 11 pertains specifically to computerized systems and the data they manage, emphasizing the importance of data integrity and availability in European Union member states.
To comply with GxP EU Annex 11, companies must ensure that critical data is stored securely and remains accessible, even in the event of regional disruptions. Enabling cross-region replication on S3 buckets is one step towards achieving this by providing a geographically distant replica of your data.
Step-by-Step Guide for Enabling Cross-Region Replication
Prerequisites:
- Two S3 buckets in different AWS regions (source and destination).
- Appropriate IAM permissions to manage S3 and replication policies.
Steps:
- 1.
Log in to AWS Management Console: You'll need to securely login to the AWS console with credentials that have the necessary permissions.
- 2.
Select the S3 service: Find and click on the S3 service within the AWS Management Console.
- 3.
Create a new S3 bucket (if necessary): If the destination bucket does not exist, create it by clicking "Create bucket" and following the on-screen instructions, making sure to select the desired region.
- 4.
Enable versioning: Versioning must be enabled on both the source and destination buckets. Select each bucket, go to the "Properties" tab, and click "Enable versioning."
- 5.
Set up replication: From the source bucket:
- Go to the "Management" tab.
- Click "Replication" and then "Add rule."
- Choose to replicate all or some of the objects. For GxP compliance, it may be necessary to replicate all objects.
- Specify the destination bucket and the storage class for the replicated data.
- 6.
Configure IAM Role: During the setup, you'll be prompted to create a new IAM role or select an existing one that will be used to perform the replication. Follow the instructions to ensure the role has the necessary permissions.
- 7.
Review and save: Review the configuration settings and save the replication rule.
Troubleshooting:
- Replication not starting: Check if versioning is enabled on both buckets.
- Permissions issues: Ensure that the IAM role has the correct policies attached to perform replication tasks.
- Replication limited to certain object tags: Confirm that replication rules are correctly configured to include all necessary objects.
Necessary AWS CLI Commands:
To setup CRR via AWS CLI:
- 1.Enable versioning on the source and destination buckets:
aws s3api put-bucket-versioning --bucket SOURCE_BUCKET_NAME --versioning-configuration Status=Enabled aws s3api put-bucket-versioning --bucket DESTINATION_BUCKET_NAME --versioning-configuration Status=Enabled
- 1.Create a replication configuration on the source bucket (JSON file
needed):replication-config.json
aws s3api put-bucket-replication --bucket SOURCE_BUCKET_NAME --replication-configuration file://replication-config.json
AWS CLI Replication Configuration JSON Example:
{
"Role": "arn:aws:iam::123456789012:role/replication-role",
"Rules": [
{
"Status": "Enabled",
"Priority": 1,
"DeleteMarkerReplication": {
"Status": "Disabled"
},
"Filter": {
"Prefix": ""
},
"Destination": {
"Bucket": "arn:aws:s3:::DESTINATION_BUCKET_NAME",
"StorageClass": "STANDARD_IA"
}
}
]
}
Ensure the replication role has necessary permissions and replace
