"At this point, it's helpful to stop treating RDS as a
competitive action against Sun/MySQL. The rest of this post could
apply equally to another open source project, the related open-core
or dual-licensed product and the related open source vendor. I
fully expect to see Amazon continue to offer open source middleware
components; RDS is the first step. I only mention Sun/MySQL below
to help explain my thinking, not to draw any conclusions to its
current or future market position."
