After the weeks and weeks of hype surrounding IBM buying Sun, Oracle today announced it was buying Sun -- for $7.4 Billion.

With Sun in tow, Oracle will now finally have its own operating system with Solaris, instead of just its own Oracle Enterprise Linux (which is based on Red Hat). Perhaps more importantly, with one swift stroke Oracle has effectively cornered even more of the database market than it already owned.

With MySQL, Oracle will have one of the leading open source databases, and a vendor that has been a bit of a competitor to Oracle over the last several years. It's a win-win for Oracle. They'll be able to continue to push their proprietary Oracle database offering, while chewing away at the open source and Web 2.0 sides of the market they didn't already hold.
