Disadvantages of Cloud Computing
Connectivity. Cloud computing requires access to the internet to function. Given that most
organisations are now completely reliant on email, electronic order processing and
potentially VoIP to run their business all of which need continuous access to the web this is
less of a consideration.
Security. Perceived security of cloud computing services is contentious and may be delaying
its adoption. It is argued that physical control of the Private Cloud equipment is more secure
than accessing equipment off site under someone else’s control. This physical control plus
the ability to visually inspect data links etc. is required to ensure data links are not
compromised and some parts of the private and public sectors unease lies in external
management of security-based services. To balance this, cloud computing service providers
prioritize building and maintaining strong management of secure services with their
reputations and client base contingent on these practices.
Physical location of the data. Certain vertical markets legal, insurance, banking etc. are
heavily regulated with stringent regulations surrounding the location of their own and their
clients’ data. This is dealt with by choice of provider and publication of the location of their
Privacy. Cloud computing allows a client to log in from any location to access data and
applications, so it seems possible the privacy could be compromised. Cloud computing
companies protect client privacy using authentication techniques with user names and
passwords and authorization format so each user can access only data and applications
relevant to their job. Also cloud computing providers are completely reliant on their
reputations for protecting client data; consequently they are focussed on the most advanced
Legal/philosophical issues. These relate to concerns over who actually owns the data; is it
the property of the user or the cloud computing service provider? And is it possible for a
cloud computing service provider to deny a client access to said data? These are the subject
of debate in academic and legal circles relating to cloud computing.
