This is a great step forward for Linux, as it opens the door for Linux to be deployed in more mission critical applications.
I should note that this is all within the Advanced Server line of products (and on a specific hardware platform to boot, but that’s another story). The basic Red Hat distribution doesn’t apply. But if you need that sort of stamp on your products, what’s a couple of grand (seeing as though your alternatives are much more expensive). Furthermore, the technologies used to obtain the certifications will be available to integrate into other distributions.
