Difference between Cloud Services and Cloud Computing
When speaking of services and computing using cloud technologies, it is often
referred to as merely cloud or as a metaphor for the Internet itself (Bufithis, 2010).
However according to Gens (2008) “cloud computing is the IT foundation for cloud
services and it consists of technologies that enable cloud services”. In other words,
cloud computing is the driving factor that only allows cloud services to benefit from
it by providing the proper hardware, software, databases, and overall IT
infrastructure. Thus cloud services are able through cloud computing.
The following table shows the key cloud computing attributes:
