Amazon Goes After Oracle (Again) With New Aurora Database
Sez Zero writes with news about the latest from Amazon Web Services. "Once again Amazon Web Services is taking on Oracle, the kingpin of relational databases, with Aurora, a relational database that is as capable as 'proprietary database engines at 1/10 the cost,' according to AWS SVP Andy Jassy. Amazon is right that customers, even big Oracle customers who hesitate to dump tried-and-true database technology are sick of Oracle’s cost structure and refusal to budge from older licensing models. Still there are very few applications that are more “sticky” than databases, which after typically contains the keys to the kingdom. Financial institutions see their use of Oracle databases as almost a pre-requisite for compliance, although that perception may be changing."

Oracle's comparison of MySQL and the Oracle database
Can't get much clearer than that.
As to performance, I'd say it varies by application/configuration. I don't use Oracle myself, but last I heard, MySQL performed better in low-resource scenarios.
