On 27 July 2015, Amazon Web Services (AWS) put Amazon RDS for Aurora (Aurora), its MySQL equivalent RDBMS platform as a service (dbPaaS), into full public availability as a managed RDBMS engine for Amazon Relational Database Service (Amazon RDS). Although accessible from anywhere in the world, it is available in the US East (Northern Virginia), US West (Oregon) and Europe (Ireland) regions, with other regions to follow. Aurora is fully compatible with Oracle MySQL 5.6 with InnoDB and is the first RDS RDBMS engine built by AWS. Aurora was originally announced at AWS re:Invent 2014. More than one thousand AWS customers participated in a nine-month preview, and many have applications in production.
