Open source software ready for big business

But Microsoft clearly understands that it must interoperate with open source platforms, even closing earlier this year its first collaboration with Red Hat to test, validate and integrate their respective virtualization platforms.

Google on the other hand has always been a heavy user of open source technology, including software that runs its internal systems.

The company's Open SourceOpen Source Programs Office maintains a link to the open source software development community, releases Google-created code, and aids in the education of open source software developers through its Google Summer of Code program. Alles zu Open Source auf CIO.de

Google Android, Google Chrome, and later this year, Google Chrome OS are some of its most visible open source efforts.

But those three also offers threats to other open source projects. So while Google is more trusted than Microsoft, it still gets a long, critical review from the open source community.
