Amazon Web Services targets MongoDB users for database migration

Public cloud leader Amazon Web Services is making another move aimed at winning over some of its rival’s customers.

The Amazon.com Inc. unit on Monday extended its Database Migration Service with support for MongoDB, the open-source NoSQL database that’s proved to be a massive hit with developers. Amazon said that its DMS service now supports migration of all NoSQL databases from on-premises infrastructures to its own servers, though many lack official support.

However, the statement means it’s likely Amazon will announce official DMS support for other databases in future. Currently, DMS supports Oracle, Microsoft SQL Server, MySQL, Amazon Aurora, PostgreSQL, and SAP SE’s ASE database.

AWS launched DMS back in 2015, saying it reduces the complexity, cost and downtime of database migration and makes it possible for customers to migrate terabyte-sized on-premises Oracle, SQL Server and open-source databases to the Amazon Relational Database Service or to another database running on Amazon’s Elastic Compute Cloud.

In December, AWS chief executive officer Andy Jassy boasted in a tweet that the service had performed 16,000 migrations in the last year, and last month in a second tweet he said that figure had risen to 22,000 migrations in total.

At the time of his first tweet, Jassy seemed to suggest the DMS feature was a useful way for companies to avoid vendor lock-in, saying “DB freedom is a powerful thing.” But critics, including Oracle Corp.’s Larry Ellison, have argued that migrating via a service like DMS just means being locked-in with a different vendor.

“Build an app on Redshift and you will be running it forever on Amazon – you are locked in, baby,” Ellison said during his keynote at Oracle OpenWorld in September. “So if Amazon raises its prices, you’d better get out your checkbook.”

In any case, Amazon hasn’t slowed down. By targeting MongoDB, which also offers a managed version of its database on the AWS cloud, the cloud giant is now directly challenging one of its own customers, and not for the first time either.
