Oracle's (ORCL) database will be available in the second quarter as part of Amazon Web Services (AMZN)' Relational Database Service, the companies announced Tuesday. The move comes shortly after Salesforce.com announced Database.com, a pay-as-you-go product that is also powered in part by Oracle's database. Like Amazon's other cloud infrastructure offerings, the upcoming Oracle database service will feature hourly fees, with no long-term contract required. Amazon already offered support for MySQL on the Relational Database Service. The addition of Oracle will give those users the same benefits of reduced database administration efforts and elastic scalability of the underlying storage and computing resources, Amazon said. Hourly pricing, which wasn't disclosed Tuesday, will depend on the Oracle database edition and instance size, Amazon said.
