Furthermore, there are also valid security and privacy concerns.
A recent survey of chief information officers and IT executives
by IDC (International Data Corporation) rated security as their
main cloud computing concern and almost 75% of respondents
said that they were worried about security. Recently, the Electronic
Privacy Information Center (a not-for-profit organization),
has filed a complaint with the US Federal Trade Commission (FTC)
about the security standards of Google’s cloud computing, arguing
that Google does not encrypt information held on its servers
(Marshall, 2009). Moreover, various governments, such as those
in the European Union (EU), have privacy regulations that prohibit
the transmission of some types of personal data outside the EU. This
issue prompted companies such as Amazon and others to develop
offerings using storage facilities located in the EU.
