Benefits of Cloud Computing
The benefits of adopting a vendor-provided cloud solution are:
1.
Economies of scale
2.
Hardware spare capacity can be fully utilized
3.
Smoothing out many peaks of demand; elasticity through internal virtualization
4.
Vendor infrastructure can be used to piggy back the client organization's mobile
apps - mass localization of previously internal applications
5.
Vendor derives value from the data that they can pass onto the users in terms of lowering
costs e.g. salesforce.com selling client information through data.com. Though this may be
seen as a security disadvantage.
6.
Fast startup - scalability
7.
Can act as competitive lever to enable a company to gain better value from internal
functions
