Amazon Redshift is the managed data warehouse solution offered by Amazon Web Services. It has a collection of computing resources called nodes, which are organized into a group called a cluster. The first node you create is called the leader node. If customers add more, they are called a compute node. Each cluster runs an Amazon […]
AWS Database Migration Service
AWS Database Migration Service helps AWS customers migrate databases to AWS quickly and securely. The source database remains fully operational during the migration, minimizing downtime to applications that rely on the database. The AWS Database Migration Service can migrate customers data to and from most widely used commercial and open-source databases.
The AWS Database Migration Service works by setting up and then managing a replication instance on AWS. This instance unloads data from the source database and loads it into the destination database, and can be used for a one-time migration followed by on-going replication to support a migration that entails minimal downtime. Along the way DMS handles many of the complex details associated with migration, including data type transformation and conversion from one database platform to another (Oracle to Aurora, for example). The service also monitors the replication and the health of the instance, notifies you if something goes wrong, and automatically provisions a replacement instance if necessary.
With AWS Database Migration Service, customers can continuously replicate their data with high availability and consolidate databases into a petabyte-scale data warehouse by streaming data to Amazon Redshift and Amazon S3. Learn more about the supported source and target databases. AWS customers can set up their first migration with a couple of clicks! they can simply create the target database, migrate the database schema, set up the data replication process, and initiate the migration. After the target database has caught up with the source, users can simply switch to using it in their production environment.

- AWS Database Migration Service can migrate customers data to and from most of the widely used commercial and open source databases. It supports homogeneous migrations such as Oracle to Oracle, as well as heterogeneous.
- AWS Database Migration Service is a low cost service. Clients only pay for the compute resources used during the migration process and any additional log storage. Migrating a terabyte-size database can be done for as little as $3.
- AWS Database Migration Service helps clients migrate their databases to AWS with virtually no downtime. All data changes to the source database that occur during the migration are continuously replicated to the target, allowing the source database to be fully operational during the migration process.
