Amazon Web Services Debuts Database Cloud Migration Service
For enterprise customers of Amazon Web Services (AWS) that have wanted to migrate their databases over to the AWS cloud, the wait is finally over. The service, which was first announced in preview in October at the Re:Invent conference in Las Vegas, has been made generally available to all AWS customers.
The AWS Database Migration Service is a fully managed service that allows customers to migrate their production Oracle, SQL Server, MySQL, MariaDB, and PostgreSQL databases from on-premises data centers to AWS. Yesterday's announcement comes just in time for AWS’ 10-year anniversary, which the company is celebrating this week.
No More Difficult Migration Choices
More than a thousand such databases have used the service to migrate to AWS’ cloud since the beginning of the year, including companies like travel Web site Expedia and industrial trade print publisher Thomas Publishing, according to Amazon.
“Customers migrating their databases to the cloud have faced a difficult choice: either take their database out of service while they copy the data (losing revenue and traffic in the process), or purchase migration tools that typically cost hundreds of thousands of dollars,” the company said in a statement.
The AWS Database Migration Service solves this problem by reducing the complexity, cost, and downtime of database migration, according to Amazon. The new service allows enterprises to migrate terabyte-size on-premises Oracle, SQL Server, and open source databases to the Amazon Relational Database Service or to a database running on Amazon Elastic Compute Cloud, the company said.
The AWS Database Migration Service monitors the progress of replication and migration, notifies customers of any network or host failures, and automatically provisions a host replacement in the event of a failure. Customers pay a simple hourly fee for the compute resources they use for migrating their database, Amazon said.
Migration Takes 30 Minutes
The migration can be done for as little as $3 per terabyte, and in under 30 minutes, according to the company. Customers can use the service to perform one-time migrations, or they can maintain continuous replication between databases without having to install or configure any complex software.
Amazon said many customer of the Database Migration Service are also using the AWS Schema Conversion Tool, which allows them to switch database engines from their existing commercial databases, converting database schemas and stored procedures from one database platform to another. About one-third of clients also switched database engines, said Hal Berenson, vice president, Relational Database Services, AWS, in the statement.
“Hundreds of customers moved more than a thousand of their on-premises databases to Amazon Aurora, other Amazon RDS engines, or databases running on Amazon EC2 during the preview of the AWS Database Migration Service,” said Berenson. “Customers repeatedly told us they wanted help moving their on-premises databases to AWS, and also moving to more open database engine options.”
