The evolution of the IT sector influences the development of other systems related to this, and the present trend seems to be the cloud concept. As information and corporate knowledge are directly involved in these processes, they represent major risks and require a high security in fields like usage or control, and IT governance establishes a solid best practice set of rules for companies. The next generation of IT governance will migrate towards Cloud computing, the data lifecycle, social media as models and will integrate existing data in multiple sources, in which security, privacy and control remain critical, vital subjects. Traditional security issues could no longer be effectively solved in the cloud, and as a result other solutions were developed to focus on Governance in the Cloud. IT governance can best manage and ensure the efficiency and effectiveness of IT as a corporate resource, but on the other hand the rapid transition to cloud technologies has fuelled some critical issues in accomplishing success for information systems, communications and security. IT governance offers visibility and IT control, therefore the efforts in corporate governance can reduce operational risks, can establish compliance and protect the invested value. As a consequence, the paper aims to recognize the importance and impact of IT governance in the evolution of IT systems and to emphasize the importance of Governance in Cloud Computing at the business level.
