This is a three-part series in which we discuss the end-to-end process of building a data lake from a legacy SQL Server database. In this post, we show you how to build data pipelines to replicate data from Microsoft SQL Server to a data lake in Amazon S3 using AWS DMS. You can extend the solution presented in this post to other database engines like PostgreSQL, MySQL, and Oracle.

In this post, we delve into the intricacies of configuring AWS DMS replication instances to use an S3 bucket in a different account. We also explore the process of establishing a connection between AWS DMS Serverless and S3 buckets across distinct accounts.

Immutable tables are a feature of Oracle Enterprise Edition, or Oracle Standard Edition database 19c and higher. In this post, we guide you through the features of immutable tables when creating, storing, and managing data on Amazon Relational Database Service (Amazon RDS) for Oracle.

In this post, we demonstrate an architecture pattern in which we migrate BLOB column data from Amazon RDS for Oracle tables to Amazon S3. This solution allows you to choose the specific columns and rows containing BLOB data that you want to migrate to Amazon S3. It uses Amazon S3 integration, which enables you to copy data between an RDS for Oracle instance and Amazon S3 using SQL.

Amazon RDS for SQL Server now supports Amazon EBS io2 Block Express volumes. These volumes are designed to support all your critical database workloads that demand high performance, high throughput, and consistently low latency. io2 Block Express volumes support 99.999% durability, up to 64 TiB storage, up to 4,000 MiB/s throughput, and up to 256,000 Provisioned IOPS for your most demanding database needs, at the same price as EBS io1 volumes. In this post, we share best practices to use the io2 Block Express volumes with RDS for SQL Server DB instances.

In September 2022, Ethereum transitioned to a Proof of Stake (PoS) consensus model. This change allows anyone with a minimum of 32 ether to stake their holdings and operate a validator node, thereby participating in network validation and earning staking rewards. In this post, we explore the technical challenges and requirements of operating an institutional-grade Ethereum staking service. Additionally, we outline a solution for deploying an Ethereum staking service on AWS.

For those seeking to achieve consistent database transaction performance, Amazon RDS has introduced a new feature: dedicated log volume (DLV). This feature is an additional storage volume specifically for database transaction logs. In this post, we examine common DLV performance benefits, use cases, monitoring capabilities, and the cost of deployment.

In this post, we showcase AWS Backup and CloudFormation support feature of AWS Backup to automate the backup of Amazon RDS for Oracle, including customized database resources such as database parameter group, option group, and security group across AWS accounts.

In this post, we show how you can use AWS Database Migration Service (AWS DMS) to migrate relational data from Amazon RDS into compressed archives on Amazon S3. We discuss partitioning strategies for the resulting archive objects and how to use S3 Object Lock to protect the archive objects from modification. Lastly, we demonstrate how to query the archive objects using SQL syntax through Athena with seconds latency, even on large datasets.

AWS has introduced a new feature in AWS Database Migration Service (AWS DMS) that simplifies the migration of data from IBM Db2 databases with the Database Partitioning Feature (DPF) databases to Amazon Simple Storage Service (Amazon S3), a highly scalable and durable object storage service. With this new capability, you can now migrate your data from IBM Db2 DPF databases to Amazon S3, paving the way for building robust data lakes in the cloud. This new feature streamlines the migration process, provides data integrity, and minimizes the risk of data loss or corruption, even when dealing with large volumes of data distributed across multiple partitions and databases of varying sizes. In this post, we delve into the intricacies of this new AWS DMS feature and demonstrate how to implement it. We explore best practices for orchestrating data flows and optimizing the migration process, achieving a smooth transition from on-premises IBM Db2 DPF databases to a cloud-based data lake on Amazon S3.
