AWS DMS provides the capability to validate your data as you migrate from various supported sources to AWS. Data integrity and accuracy is one of key requirements we often hear about from our customers that determines a successful migration project. In this post, we delve deep into AWS DMS data validation feature. We explore its benefits, configurations, and use cases.

Different types of blockchain applications and users demand varying types of private key management solutions, referred to as wallets. Custodial wallets are managed by third-party vendors such as a centralized crypto exchange, whereas non-custodial wallets give you full control and ownership over your private keys and funds. In this post, we focus on multi-party computation (MPC) wallets. We introduce the core concepts of MPC wallets, including the security features they offer that make MPC wallets uniquely well suited for institutional customers. We also detail the most critical aspects of implementing a distributed, highly secure MPC wallet on AWS, including a design for a single MPC cosigner that uses AWS Nitro Enclaves to protect the most sensitive information: the key shards.

In this post, we explore the key considerations and best practices for implementing effective DR strategies for your Amazon Neptune database deployments.

In this post, we show how you can use the Timestream for LiveAnalytics Prometheus Connector to use Timestream for LiveAnalytics as remote storage for Prometheus with one-click deployment.

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.

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.

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.

In this post, we show how to use Aurora Global Database to build a resilient multi-Region application and the best practices for this setup.

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.

In a previous post, we described how to connect Amazon Neptune to metaphactory, securely, and then how to explore and search the Neptune graph data using metaphactory. In this post, we show how you can use metaphactory to build an end user application using its dynamic model driven components, driven by SPARQL queries.
