To retain CDC configurations, customers can specify the KEEP_CDC option when restoring a database backup. This option ensures that the CDC metadata and any captured change data are kept intact. Refer to the Amazon RDS for SQL Server User Guide to learn more about KEEP_CDC. This feature is available in all AWS Regions where Amazon RDS for SQL Server is available.

Amazon Relational Database Service (Amazon RDS) for SQL Server now supports Multi-AZ deployment for SQL Server Web Edition. SQL Server Web Edition is specifically designed to support public and internet-accessible web pages, websites, web applications, and web services, and is used by web hosters and web value-added providers (VAPs). These applications need high availability, and automated failover to recover from hardware and database failures. Now customers can use SQL Server Web Edition with Amazon RDS Multi-AZ deployment option, which provides a high availability solution. The new feature eliminates the need for customers to use more expensive options for high availability, such as using SQL Server Standard Edition or Enterprise Edition. To use the feature, customers simply configure their Amazon RDS for SQL Server Web Edition instance with Multi-AZ deployment option. Amazon RDS automatically provisions and maintains a standby replica in a different Availability Zone (AZ), and synchronously replicates data across the two AZs. In situations where your Multi-AZ primary database becomes unavailable, Amazon RDS automatically fails over to the standby replica, so customers can resume database operations quickly and without any administrative intervention. For more information about Multi-AZ deployment for RDS SQL Server Web Edition, refer to the Amazon RDS for SQL Server User Guide. See Amazon RDS for SQL Server Pricing for pricing details and regional availability.

https://aws.amazon.com/rds/sqlserver/ now supports differential and transaction log restores for instances configured with Multi-AZ and instances with read replicas in the same region. The native SQL Server backup and restore component provides an essential safeguard for protecting critical data stored in your SQL Server databases, and it allows you to migrate your databases between different environments, such as from on-premises to Amazon RDS for SQL Server. Differential backups are cumulative backups of all data changes that have occurred since the most recent full backup, while transaction log backups record every single transaction in the database. Combining these with full backups you can create a disaster recovery strategy to minimize data loss. Previously, customers who needs to use native SQL Server differential and transaction log restores were required to remove Multi-AZ and Read Replica so that the instance is in Single-AZ mode, restore the databases, and then reconfigure the instance back to Multi-AZ and Read Replica. Now customers can reduce the restore time by using differential and transaction log restores directly on these instances without having to convert them to Single-AZ first, while keeping Multi-AZ working for high availability, and read replica working to serve read workloads in the same region. For more information about using differential and transaction log restores, see the https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/SQLServer.Procedural.Importing.html. This feature is available in all AWS Regions where Amazon RDS for SQL Server is available.

Amazon RDS for SQL Server launches optimize CPU with support for M7i and R7i instance families, which reduce prices by up to 55% compared to equivalent previous generation instances. Optimize CPU optimizes Simultaneous Multi-threading (SMT) configuration to reduce commercial software charges. Customers can lower cost by upgrading to M7i and R7i instances from similar 6th generation instances. Furthermore, for memory or IO intensive database workloads, customers can get additional cost reduction by fine tuning optimize CPU configuration. RDS for SQL Server price for database instance hours consumed is inclusive of Microsoft Windows and Microsoft SQL Server software charges. Optimize CPU disables SMT for instances with 2 or more physical CPU cores. This reduces the number of vCPUs, and the corresponding commercial software charges by 50% while providing the same number of physical CPU cores, and near equivalent performance. The most significant savings are available on 2Xlarge and higher instances, and instances that use Multi-AZ deployment, where RDS optimizes to reduce SQL Server software charges for only a single active node for most usage. For workloads that are memory or IO intensive, customers can fine tune the number of active physical CPU cores for further savings. RDS for SQL Server supports M7i and R7i instances in all AWS Regions. With unbundled instance pricing, database costs are calculated with separate charges for third party licensing fees per vCPU hour, and third party licensing fees are not eligible towards your organization’s discounts with AWS. You can view Microsoft Windows and SQL Server charges associated with your usage on AWS Billing and Cost Management, and in monthly bills.
