Amazon RDS April 2019 Update

Released on April 26th, 2019

Amazon RDS now Supports Per-Second Billing

Starting today, Amazon RDS is billed in one-second increments for database instances and attached storage. Pricing is still listed on a per-hour basis, but bills are now calculated down to the second and show usage in decimal form. There is a 10 minute minimum charge when an instance is created, restored or started.

Per-second billing is applicable to instances that are newly launched or already running in all AWS Regions except AWS GovCloud (US). Please visit the Amazon RDS pricing page for more information.

Amazon RDS for PostgreSQL Now Supports Data Import from Amazon S3

Amazon RDS for PostgreSQL now supports importing of data stored in a Amazon Simple Storage Service (S3) bucket into a PostgreSQL table. A new extension aws_s3 has been added and will be used to perform the import operations. You can import any data format that is supported by the PostgreSQL COPY command using ARN role association method or using Amazon S3 credentials.

PostgreSQL versions 11.1 and above are supported with this feature. To learn more, please visit the documentation page.

Amazon RDS for PostgreSQL makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. See Amazon RDS for PostgreSQL Pricing for regional availability.

Amazon Aurora and Amazon RDS Enable Faster Migration from MySQL 5.7 Databases

You can now restore MySQL 5.7 backups stored in Amazon S3 to Amazon Aurora with MySQL compatibility and Amazon RDS for MySQL.  

If you are migrating a MySQL 5.5, 5.6, or 5.7 database to Aurora with MySQL compatibility or RDS for MySQL, you can copy database backups to an Amazon S3 bucket and restore them for a faster migration. Both full and incremental backups of your database can be restored. Restoring backups can be considerably quicker than moving data using the mysqldump utility, which replays SQL statements to recreate the database.

Restore your database backups with just a few clicks on the AWS management console or alternatively, use the latest AWS SDK or CLI. Refer Aurora with MySQL compatibility and RDS for MySQL documentation to learn more about migrations using database backups.

Amazon RDS for PostgreSQL Now Supports Multi Major Version Upgrades to PostgreSQL 11

Amazon RDS for PostgreSQL now supports Multi Major Version Upgrades for PostgreSQL which allows you to perform major version upgrades across multiple different major versions.

Previously, major version upgrades could only be done to one higher version at a time. For example, PostgreSQL version 9.6 could only be upgraded to PostgreSQL 10, and PostgreSQL version 9.4 to PostgreSQL version 9.5. So, if you wanted to upgrade your older instances to the latest major version, you would have to perform multiple major version upgrades until you reached your target version. For example, upgrading PostgreSQL 9.4 to PostgreSQL 11 involved upgrading from version 9.4 to 9.5, then 9.5 to 9.6, and then 9.6 to 10 and finally from 10 to 11. This caused extended downtime for each of the upgrade operations.
With the new multi major version upgrade feature you can perform any of the following upgrades seamlessly in a single step, thus reducing downtime substantially.

  • Upgrade from PostgreSQL version 9.4 to PostgreSQL version 11
  • Upgrade from PostgreSQL version 9.5 to PostgreSQL version 11
  • Upgrade from PostgreSQL version 9.6. to PostgreSQL version 11

In addition, if you are still running any PostgreSQL version 9.3 which has already been out of support, you can upgrade your instance(s) to 9.5 or 9.6 directly.

Please refer to the major version upgrade documentation on details around the PostgreSQL versions that are supported as source and target versions and also any limitations associated with the upgrade process.

With this release, RDS for PostgreSQL now also supports upgrading from PostgreSQL 10 to PostgreSQL 11.

Amazon RDS for PostgreSQL makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. Learn more about upgrading your database instances from the Amazon RDS User Guide. See Amazon RDS for PostgreSQL Pricing for pricing details and regional availability.

Amazon RDS Enhnced Monitoring Adds New Storage and Host Metrics

Amazon Relational Database Service (RDS) Enhanced Monitoring, which provides visibility into the health of your Amazon RDS instances, now reports physical storage device metrics and secondary instance host metrics.

When the Amazon RDS storage is using more than one underlying physical device, Enhanced Monitoring collects the data for each device. In addition, when the DB instance is running in a Multi-AZ configuration, the data for each device on secondary host is collected as well secondary host metrics.  

Both physical device and Multi-AZ secondary host metrics are available on RDS for Oracle, PostgreSQL and MySQL. With data reported on each physical device, you can see how many physical devices make up their volumes, if I/O is balanced across physical devices, and see if latency is consistent across physical devices.

For a complete list of available metrics and more information on how to use this feature, see Enhanced Monitoring documentation. You can seamlessly integrate Enhanced Monitoring with third-party applications to monitor your Amazon RDS DB instances. Once you enable Enhanced Monitoring, you will incur standard CloudWatch Logs charges. For more details on pricing, go to CloudWatch Logs pricing.  

AWS Backup is Now Available in the AWS Asia Pacific (Sydney) and EU (Frankfurt) Regions

AWS Backup is now available in the AWS Asia Pacific (Sydney) and EU (Frankfurt) Regions.

AWS Backup is a fully managed backup service that makes it easy to centralize and automate the back up of data across AWS services in the cloud as well as on premises. With AWS Backup, protecting your AWS resources, such as Amazon EFS file systems, is as easy as a few clicks in the AWS Backup console. Customers can configure and audit the AWS resources they want to back up, automate backup scheduling, set retention policies, and monitor all recent backup and restore activity.

Using AWS Backup, you can centrally configure backup policies and monitor backup activity for AWS resources, such as Amazon EBS volumes, Amazon RDS databases, Amazon DynamoDB tables, Amazon EFS file systems, and AWS Storage Gateway volumes. AWS Backup provides a fully managed, policy-based backup solution, simplifying your backup management, enabling you to meet your business and regulatory backup compliance requirements. As customers build their applications in the AWS Cloud, data can become distributed across multiple AWS services, including database services, block storage, object storage, and file systems. While these services have backup capabilities, customers often create custom scripts to automate backup scheduling, enforce retention policies, and consolidate backup activity across AWS services.

AWS Backup is available in the US East (Northern Virginia), US East (Ohio), US West (Oregon), EU (Frankfurt), EU (Ireland), and Asia Pacific (Sydney) Regions. For more information on where AWS Backup is available, see the AWS region table. Learn more on the AWS Backup page and the latest blog.
