Amazon has announced general availability of its AWS Database Migration Service, aimed at helping organisations to move production database systems from their own infrastructure to the AWS cloud with minimum disruption and at minimum cost.
The AWS Database Migration Service was first announced as a preview at the firm's AWS re:Invent user conference in Las Vegas last autumn, but is now officially available to all AWS customers.
Amazon claims that the fully managed service enables an IT professional to migrate a database to AWS securely, cost-effectively and with no downtime, and also enables them to migrate the data set itself from one database engine such as Oracle, to another such as PostgreSQL.
The service has been developed to tempt organisations into offloading some or all of their database deployments from their own infrastructure and onto Amazon's cloud platform, either using the Amazon Relational Database Service (Amazon RDS) or by provisioning clusters of Amazon EC2 virtual machines running the database management system of their choice.
Until now, a major stumbling block has been the need for the customer to take their database offline while they copy the data, or else purchase migration tools that typically cost hundreds of thousands of dollars, Amazon said.
In contrast, the AWS Database Migration Service can accomplish the process with just a few clicks in the AWS Management Console, and because customers pay only for the compute resources used during the migration process, a terabyte-sized database can be migrated for as little as $3, Amazon claims.
The service supports Oracle, SQL Server, PostgreSQL, Amazon Aurora, MySQL, or MariaDB as sources for the migration, while an AWS Schema Conversion Tool can also be used to convert database schemas and stored procedures from one database platform to another.
This will typically be used to let customers migrate their applications from Oracle or SQL Server to Amazon Aurora or one of the open source engines supported in Amazon RDS, the firm said.
Hundreds of customers have already used the AWS Database Migration Service to successfully migrate thousands of databases during its preview period, according to Hal Berenson, AWS vice president, for Relational Database Services.
"Customers repeatedly told us they wanted help moving their on-premises databases to AWS, and also moving to more open database engine options, but the response to the AWS Database Migration Service has been even stronger than we expected," he said.
The AWS Database Migration Service is available now from Amazon's US Regions; from the EU Ireland and Frankfurt Regions; and from the Asia Pacific. Amazon said it will expand to additional Regions in the coming months.
