We’re excited to present the first edition of the Microsoft SQL Server to Amazon Aurora MySQL Compatibility Migration Playbook. AWS Database Migration Service (AWS DMS) and AWS Schema Conversion Tool (AWS SCT) help you reduce the effort associated with migration from commercial engines to open-source and Amazon-managed databases. Thus, they help reduce cost and avoid […]

In this blog post, we show you how to configure the CloudWatch agent on Amazon EC2 Windows instances to capture custom metrics for SQL Server from Windows performance monitor. We also show you how to publish those custom metrics and monitor them on Amazon CloudWatch console. We also walk you through on how to store custom configuration in AWS Systems Manager Parameter Store used by CloudWatch agent to capture those metrics and reuse the same configuration across multiple fleets of SQL Server instances where similar kind of metrics are needed.

This blog post focuses on general data security patterns and corresponding AWS security controls that protect your data. Although I mention Amazon RDS and DynamoDB in this post, I plan to cover the implementation-specific details related to Amazon RDS and DynamoDB in two subsequent posts.

This post describes Amazon RDS Single-AZ RTO and RPO expectations for MySQL, MariaDB, PostgreSQL, Oracle, and Microsoft SQL Server databases. Amazon Aurora uses a different technology and storage subsystem designed for the cloud. Its single instance recovery process and scenarios are described in the Aurora FAQ.

In this post, I demonstrate several ways to use global secondary indexes to query your data, accelerate your application’s performance, and reduce your monthly DynamoDB bill.

Databases are core to many of our applications at Intuit. The database team has been working out which architecture to standardize on and what run books and tools to build in order to migrate and then operate in the cloud. We realized that the fastest way to resolve our questions would be to take one of our existing on-premises applications and run it through an actual migration to Amazon Aurora.

In this post, we look at how to use virtual partitioning to optimize your data warehouse migrations using AWS SCT. Virtual partitioning speeds up large table extraction using parallel processing. It is a recommended best practice for data warehouse migrations.

Update (December 14, 2020): The DynamoDB team recommends that you use Amazon CloudWatch Contributor Insights for Amazon DynamoDB, which is a diagnostic tool for understanding your traffic patterns and identifying frequently accessed keys. You can enable CloudWatch Contributor Insights for DynamoDB in the AWS Management Console, or in the AWS API or AWS CLI. August […]
