How to clone master user permissions in Amazon RDS for SQL Server

When you create a new Amazon Relational Database Service (Amazon RDS) for SQL Server instance, the master user is granted certain privileges for that database instance. We strongly recommend that you do not use the master user directly in your applications. Instead, adhere to the principles of least privilege and best practices by using a database user created with the minimal permissions required for your application. In this post, we discuss how to clone the master user to a new login and review it for the minimal permissions required.

Understanding Amazon Aurora MySQL storage space utilization

Storage in Amazon Aurora MySQL is managed differently from traditional MySQL databases. In this post, we explore the different types of storage available in Amazon Aurora MySQL, how Aurora uses those storage types, and how to monitor storage consumption. We also explore some of the database queries and Amazon CloudWatch metrics for Aurora that you can use to estimate Aurora storage billing.

How London Stock Exchange Group optimised blue/green deployments for Amazon Aurora PostgreSQL Global Database

In this post we share how the London Stock Exchange Group (LSEG) Capital Markets Business unit improved their Blue/Green software deployment methodology, by using continuous logical database replication. We show you the process of implementing a Blue/green deployment architecture using Aurora PostgreSQL Global Database. Specifically, we explore best practices and considerations when configuring the architecture. Blue/green deployment serves as a robust and efficient approach to make sure applications stay resilient and synchronized throughout the process.

AWS DMS homogenous migration from PostgreSQL to Amazon Aurora PostgreSQL

With AWS DMS homogenous migration, you can migrate data from your source database to an equivalent engine on AWS using native database tools. In this post, we show you an example of a complete homogeneous migration process and provide troubleshooting steps for migrating from PostgreSQL to Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL.

Use Spring Cloud to capture Amazon DynamoDB changes through Amazon Kinesis Data Streams

In this post, we demonstrate how you can use Spring Cloud to interact with Amazon DynamoDB and capture table-level changes using Kinesis Data Streams through familiar Spring constructs. We run you through a basic implementation and configuration that will help you get started.

Application Continuity for Oracle workloads with Amazon RDS Custom for Oracle

In this post, we show you how to implement Application Continuity in an RDS Custom for Oracle environment using a sample application. We also show you how to test the implementation to see that, when an outage occurs at the database tier, the application recovers and resumes without any data loss—automatically and transparently—along with the database failover. Finally, we show you how to verify the results before cleaning up the environment.

Optimize Amazon RDS costs for predictable workloads with automated IOPS and throughput scaling

In this post, we explain how you can use Amazon RDS IOPS and throughput provisioned settings, automate scaling around monthly and seasonal peaks, and decrease settings during slower weeks. By right-sizing IOPS and throughput levels to your workload’s typical cycles, you can reduce Amazon RDS spend while still getting great performance when you need it most.

Use Amazon DynamoDB incremental exports to drive continuous data retention

Amazon DynamoDB supports incremental exports to Amazon Simple Storage Service (Amazon S3), which enables a variety of use cases for downstream data retention and consumption. In this post, we show you how to maintain a continuously updating export of your table data by doing a bootstrap full export followed by an ongoing series of incremental exports.

Near zero-downtime migrations from self-managed Db2 on AIX or Windows to Amazon RDS for Db2 using IBM Q Replication

When you’re migrating your mission-critical Db2 database from on premises or Amazon Elastic Compute Cloud (Amazon EC2) to Amazon RDS for Db2, one of the key requirements is to have near-zero downtime. This post demonstrates how to use IBM InfoSphere Data Replication (IIDR) Q Replication to migrate data with minimal downtime.
