The Ultimate Guide to Data Migration Service of AWS

AWS DMS is a cloud-based server that runs replication software. Once a user creates a connection between the source and the target databases for migration, AWS DMS automatically picks up from where to migrate data and to which location. A task is then set up that moves the data on this server even if the related primary keys and tables required for migration are not present in the target database. Users can also create the target tables or use the Schema Conversion tool to create the target tables, views, indexes, and triggers.

AWS DMS migration helps to replicate changes and incremental data so that the source and the target databases are always in sync. But if migration is required to a different database engine, the SCT is used to transform the database schema to a new platform after which the AWS DMS migration can take place. AWS DMS migration is an integral part of the AWS Cloud and hence, migrating to the cloud with AWS DMS offers a lot of benefits.
AWS DMS migration has several cutting-edge advantages.

• Database migration before was a complex and time-consuming procedure. Additional hardware and software had to be installed and administered and systems tested and debugged before migration. But with AWS DMS migration, deploying, managing, and monitoring all infrastructure needed for migration are done automatically. The process is started within a few minutes of the configuration of AWS DMS.

• Data storage facilities during migration can be scaled up or down as per needs and the user has to pay only for the quantum of resources used. If additional resources are required AWS DMS allocates it within a few minutes and the data migration is resumed immediately after. In traditional licensing models, upfront fees and substantial maintenance charges had to be paid.

• Automatic fail over in case of an outage during database transfer is a critical feature of AWS DMS migration. If there is a failure of the primary server during migration, other servers in the same region or any other take up the slack, and migration through secondary servers goes on without a break. Once the outage is resolved, the primary server is updated with the incremental changes, and the migration is resumed as before.

• Everything that is required for migration and the related infrastructure is managed by AWS DMS including monitoring of hardware and software, error reporting, and software patching.

• AWS DMS enables businesses to switch over to a more cost-effective database engine than the ones being used traditionally. With AWS DMS migration, users get the benefit of managed database services from Amazon Aurora or Amazon Relational Database Service. It is also possible to move to fully managed data warehouse services like Amazon Redshift, NoSQL platforms like Amazon DynamoDB, or cost-effective storage platforms such as Amazon S3.

All these benefits make AWS DMS migration a preferred platform for moving databases to the Cloud.
