Migrating relational databases to Amazon DocumentDB (with MongoDB compatibility)
If your data is stored in existing relational databases, converting relational data structures to documents can be complex and involve constructing and managing custom extract, transform, and load (ETL) pipelines. Amazon Database Migration Service (AWS DMS) can manage the migration process efficiently and repeatably. With AWS DMS, you can perform minimal downtime migrations, and can replicate ongoing changes to keep sources and targets in sync. This post provides an overview on how you can migrate your relational databases like MySQL, PostgreSQL, Oracle, Microsoft SQL Server, and others to Amazon DocumentDB using AWS DMS.
Streaming data to Amazon Managed Streaming for Apache Kafka using AWS DMS
AWS Database Migration Service (DMS) announced support of Amazon Managed Streaming for Apache Kafka (Amazon MSK) and self-managed Apache Kafka clusters as target. With AWS DMS you can replicate ongoing changes from any DMS supported sources such as Amazon Aurora (MySQL and PostgreSQL-compatible), Oracle, and SQL Server to Amazon Managed Streaming for Apache Kafka (Amazon MSK) and self-managed Apache Kafka clusters.
In this post, we use an e-commerce use case and set up the entire pipeline with the order data being persisted in an Aurora MySQL database. We use AWS DMS to load and replicate this data to Amazon MSK. We then use the data to generate a live graph on our dashboard application.
Automating database migration monitoring with AWS DMS
AWS Database Migration Service (AWS DMS) is a cloud service that makes it easy to migrate relational databases, data warehouses, NoSQL databases, and other types of data stores. During data migration with AWS DMS, it’s important to monitor the status of the ongoing replication tasks, which you can do on the task’s control table and with Amazon CloudWatch.
Effectively migrating LOB data to Amazon S3 from Amazon RDS for Oracle with AWS DMS
In this post, I walk through an effective way to migrate and continuously replicate tables with LOB columns from Amazon RDS for Oracle to Amazon S3 using AWS Database Migration Service (AWS DMS). This service helps you migrate on-premises databases to AWS quickly and securely. In this post, we explore its heterogeneous replication feature.
Achieving minimum downtime for major version upgrades in Amazon Aurora for PostgreSQL using AWS DMS
AWS provides two managed PostgreSQL options: Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL. When Amazon RDS or Aurora support a new major version of a database engine, for example, PostgreSQL 10 to 11, you can upgrade your DB instances to the new version. Major version upgrades can contain database changes that may not be […]
Rolling back from a migration with AWS DMS
When migrating a database to a new system using AWS Database Migration Service (DMS), it is prudent to have a fallback strategy if the new system doesn’t work as expected. At a high level, there are four basic strategies for rolling back from a migration: basic fallback, fall forward, dual write, and bidirectional replication. Depending […]
Configuring SSL encryption on Oracle and PostgreSQL endpoints in AWS DMS
AWS Database Migration Service (DMS) helps you migrate databases to AWS securely. It supports homogeneous and heterogeneous migrations between different database platforms, such as Oracle to Amazon Aurora. AWS DMS supports continuous data replication while maintaining high availability and has been widely adopted for database migrations because it is easy to configure. For more information, […]
Continuous database replication using AWS DMS to migrate from Oracle to Amazon Aurora
This is a guest post from IPG. In their own words, “IPG, based in Japan, specializes in TV-related data. We use data from broadcasters across Japan, format it for easy use and understanding, structure it with metatags, and make it simple to use on any platform, like smartphones.” This post discusses the different optimizations we […]
Migration tips for developers converting Oracle and SQL Server code to PostgreSQL
PostgreSQL is one of the most popular open-source relational database systems. It is considered to be one of the top database choices when customers migrate from commercial databases such as Oracle and Microsoft SQL Server. AWS provides two managed PostgreSQL options: Amazon RDS and Amazon Aurora. In addition to providing managed PostgreSQL services, AWS also […]
Automating table mappings creation in AWS DMS
AWS Database Migration Service (AWS DMS) helps you migrate on-premises databases to AWS quickly and securely. It supports homogeneous migrations as well as heterogeneous migrations. The source database remains operational while the migration is running or being tested. Migration takes place using a DMS replication server, source, target endpoints, and migration tasks. If you are […]
