Reports are suggesting that Amazon Web Services will announce a PostgreSQL-compatible managed cloud service at its re:Invent conference next week.

Fortune reports that the new PostgreSQL-compatible database engine will be similar to AWS’s Aurora service, the MySQL-compatible relational database engine it launched last year, which it now claims is the fastest-growing service in its history. The motivation is simple enough, of course: It’s all about pulling in more managed services revenues, Fortune said in its report, which cites several sources “familiar with the plan.”

Those sources told Fortune that the move “makes sense given Amazon’s focus on winning Fortune 500 accounts,” as an affordable PostgreSQL database would be compared to MySQL via larger vendors. AWS’s existing Relational Database Service already lets users access PostgreSQL, as well as Amazon Aurora, MySQL, MariaDB, Microsoft SQL Server and Oracle.

In addition to the new PostgreSQL-compatible managed cloud service, AWS is also planning to make the machine learning technology that powers its personal assistant Alexa available to cloud and developer customers, an area where the company lags behind rivals Microsoft and Google, Fortune’s sources said.

AWS may also introduce a new, more flexible option for its basic cloud computing service, Elastic Compute Cloud, which will let customers add or delete memory or processor cores as needed, Fortune reported. The new option would be similar to the Google Custom Machine Types announced early this year.

AWS declined to comment on Fortune’s report.
