Rule: RDS DB Instance Multiple AZ Should Be Enabled
This rule ensures that RDS DB instances have multiple availability zone enabled for high availability.
| Rule | RDS DB instance multiple az should be enabled |
| Framework | GxP 21 CFR Part 11 |
| Severity | ✔ Low |
Rule Description:
In order to ensure compliance with GxP regulations and 21 CFR Part 11 requirements, it is necessary to enable multiple Availability Zones (AZs) for Amazon RDS (Relational Database Service) DB instances. By enabling multiple AZs, you ensure high availability and fault tolerance for your database environment. This is particularly important for GxP systems as it helps to minimize the risk of data loss and downtime.
Troubleshooting Steps:
If multiple AZs are not enabled for your RDS DB instance, follow these troubleshooting steps:
- 1.Check the current configuration of your RDS DB instance.
- 2.Determine if multiple AZs are currently enabled or not.
- 3.If multiple AZs are not enabled, proceed to the next step.
Necessary Codes:
There are no specific codes required for this rule. The configuration change needs to be performed through the AWS Management Console or using AWS CLI commands.
Step-by-Step Guide for Remediation:
To enable multiple AZs for your RDS DB instance, follow these step-by-step instructions:
- 1.
Open the AWS Management Console and navigate to the Amazon RDS service.
- 2.
Select the appropriate region where your RDS DB instance is located.
- 3.
In the left navigation panel, click on "Databases" to view your existing RDS DB instances.
- 4.
Locate the DB instance for which you want to enable multiple AZs and click on its identifier.
- 5.
On the details page for the DB instance, click on the "Modify" button.
- 6.
Scroll down to the "Multi-AZ deployment" section and check the box labeled "Enable Multi-AZ deployment."
- 7.
Optionally, you can specify the backup retention period under the "Backup" section. This determines how long automated backups should be retained.
- 8.
Click on the "Apply immediately" checkbox to apply the changes immediately or choose a specific maintenance window for the change.
- 9.
Review the modifications and click on the "Modify DB instance" button to save the changes.
- 10.
Wait for the modification to complete. The process may take a few minutes depending on the size of your database instance.
- 11.
Once the modification is complete, your RDS DB instance will be configured with multiple AZs, providing enhanced availability and data protection for GxP compliance.
Note: Enabling multiple AZs may incur additional costs due to the replicated resources in the additional AZ. Make sure to review and understand the associated cost implications before making the changes.
Conclusion:
By enabling multiple AZs for your RDS DB instance, you ensure compliance with GxP regulations and 21 CFR Part 11 requirements. This configuration provides improved availability and data protection, reducing the risk of data loss and downtime. Following the step-by-step guide mentioned above will help you successfully enable multiple AZs for your RDS DB instances.
