Understanding Extended Support Versions¶
What is Amazon RDS Extended Support?¶
Amazon RDS Extended Support allows users to run their PostgreSQL databases on RDS for an extended period after the community has ceased support for a major version. For an additional three years, Amazon will provide critical security patches and bug fixes, ensuring your databases remain secure and operational despite the standard support phase ending.
Benefits of Extended Support¶
Here are several reasons why choosing Extended Support versions is beneficial:
- Extended Security Patches: More time to upgrade while maintaining access to essential security updates.
- Stable Operation: Continued support ensures the databases won’t be left vulnerable or unstable.
- Improved Performance: Upgrading to the latest minor versions enhances database reliability, speed, and efficiency.
Key Features of the New Minor Versions¶
Security Updates¶
Minor versions 11.22-rds.20250508 and 12.22-rds.20250508 come packed with critical security updates that protect your databases from vulnerabilities. Making timely upgrades can greatly mitigate risks associated with outdated security protocols.
Bug Fixes¶
Alongside security updates, these versions tackle various bugs previously reported by users. By upgrading, you not only enhance security but also resolve underlying issues that may impact your database’s performance.
How to Upgrade to Extended Support Versions¶
Pre-Upgrade Considerations¶
Before you embark on the upgrade process, consider the following factors:
- Compatibility Checks: Ensure your applications and frameworks maintain compatibility with the new versions.
- Performance Testing: Run benchmarks to understand your database performance pre- and post-upgrade.
- Backup: Always take a complete backup of your database to prevent data loss in case of an error during the upgrade.
Step-by-Step Upgrade Process¶
- Log into the AWS Management Console: Choose your RDS instance running PostgreSQL.
- Modify Instance: Click on the “Modify” button.
- Select New Version: Choose the desired Extended Support version from the options available in the “DB Engine Version” dropdown.
- Review Changes: Confirm changes and click on “Continue.”
- Scheduling: Choose a maintenance window that fits your database’s traffic patterns, ensuring minimal disruption.
- Apply Changes: Apply the changes to begin the upgrade process.
Using Automatic Minor Version Upgrades¶
You can utilize the automatic minor version upgrade feature to ensure that your PostgreSQL databases are consistently updated during scheduled maintenance windows:
- Navigate to the Management Console: Find your RDS instance settings.
- Enable Automatic Upgrades: Under the “DB Instance” settings, check the option for automatic minor version upgrades.
Leveraging Amazon RDS Blue/Green Deployments¶
Amazon RDS Blue/Green Deployments facilitate a seamless upgrade process by allowing you to create a separate, isolated environment for testing the new version, minimizing downtime:
- Create a Blue Environment (Current Version): Maintain your stable database in the existing environment.
- Set Up Green Environment (New Version): Launch a parallel environment with the new version.
- Data Synchronization: Use physical replication to sync data between the two environments.
- Testing: Rigorously test the Green environment to ensure there are no issues before switching.
- Switch Traffic: Carefully redirect traffic to the Green environment once satisfied with its performance.
Managing PostgreSQL Databases in the Cloud¶
Scaling Your Database¶
With RDS for PostgreSQL, managing scale is straightforward:
- Vertical Scaling: Increase the instance size with more CPU and memory resources.
