Cloud
Computing: who should use it?
•Cloud
computing definitely makes sense if your own securityis weak, missing features,
or below average.
•Ultimately,
if
–the cloud provider’s security people are
“better” than yours (and leveraged at least as efficiently),
–the web-services interfaces don’t introduce
too many new vulnerabilities, and
–the cloud provider aims at least as high as
you do, at security goals,
then
cloud computing has better security.
