Open Source in the Enterprise

An O'Reilly Radar Report

Using open source in the enterprise — the question is no longer "if," but "how?" The low cost, easy access, and expansive license terms of open source are certainly attractive — especially since IT budgets have decreased 3-5% every year, while software costs have increased, and IT staffs have been tasked to create web services and pursue Web 2.0 initiatives.
