This document discusses some of the key legal issues related to cloud computing. It covers 3 areas: 1) personal data protection laws which cloud computing exposes issues with due to reduced user control and complex application of laws across borders, 2) contracting issues where cloud contracts often limit liability to levels below potential risks and include other problematic clauses, and 3) liability for illegal data where cloud providers need to balance storage protections with processing activities and respond to takedown notices. Compliance with various regulations is also challenging for cloud services.
