WAX is a blockchain-based system designed for the unique demands of the gaming industry. It provides high transaction throughput and near-instant block finality. With WAX, game developers can decouple in-game digital assets from a single in-game world and let gamers use them in new contexts such as building walls of fame, creating personal online trophy […]

Run a serverless Arbitrum full node on AWS

Over the last 2 years, layer 2 technologies have gained traction and are solving the scaling constraints of Ethereum. L2beat provides a consolidated view of the different layer 2 projects. At the time of writing, Arbitrum represents approximatively half of the market value of layer 2 solutions. AWS offers a variety of services to help […]

Trigger an AWS Lambda function from Amazon RDS for MySQL or Amazon RDS for MariaDB using audit logs and Amazon CloudWatch

AWS Lambda is a serverless compute offering that helps you design event-driven architectures. It provides direct integration with multiple AWS services, including Amazon Aurora MySQL-Compatible Edition. In this post, we show you how to invoke Lambda functions from Amazon Relational Databases Service (Amazon RDS) for MySQL and Amazon RDS for MariaDB using Amazon CloudWatch and […]

Build a mortgage-backed securities data model using Amazon Neptune

As organizations adopt modern application architectures such as microservices, application teams tend to retrofit one-size-fits-all databases. The mortgage industry is going through unprecedented transformation due to changing generation technologies such as API adoption.

Introducing the Data API for Amazon Aurora Serverless v2 and Amazon Aurora provisioned clusters

Traditionally, applications that communicate with relational databases use drivers that provide a persistent connection between the application and the database server. With the advent of serverless applications, including those created using AWS Lambda, persistent connections from the application are no longer practical because serverless applications are, by nature, stateless. What’s more, traditional database drivers often […]

Join SQL Server on AWS to Microsoft Entra Domain Services

Many customers use Microsoft Entra ID (previously Azure AD) as their identity provider for Windows authentication. With the launch of support to join Amazon RDS for SQL Server to self-managed Active Directory, you can now join your Amazon Relational Database […]

Connect to MySQL and MariaDB from Amazon Aurora and Amazon RDS for PostgreSQL using the mysql_fdw extension

When dealing with multiple database engines or schemas that share data with each other, you’re faced with the difficulty of establishing cross-engine database connectivity. To overcome this challenge, PostgreSQL offers foreign data wrappers (FDW), which are libraries that facilitate communication with external data sources by abstracting the complexities of data source connection and data retrieval. […]

Schedule scaling for Amazon Aurora replicas using AWS Application Auto Scaling

In this post, we demonstrate how to modify the Amazon Aurora reader auto scaling configuration on a schedule using AWS Application Auto Scaling, on top of the existing auto scaling policies. When your application grows, the load on your database will most likely grow as your application saves larger amounts of data. Whether it’s the […]

Automatically scale Amazon RDS storage using Amazon CloudWatch and AWS Lambda

Customer databases are constantly growing. When you increase storage for a database in Amazon Relational Database Service (Amazon RDS), you can’t make further storage modifications for either 6 hours or until storage optimization has completed on the instance, whichever is longer. Amazon RDS storage autoscaling increases storage by 10 GiB, 10% of currently allocated storage, […]
