What are the Cloud Services?
Doesn't the Application Software itself provides a Service?
Besides Software as a Service (SaaS) (the application part of
Utility Computing
), there are
Infrastructure as a Service (the equipment part of Utility Computing)
Platform as a Service (Utility Computing)
Storage as a Service (Disk, databases)*
Network as a Service (Guaranteed bandwith)
Monitoring as a Service(special application)
In general,
XaaS
.
This is like renting the car instead of buying it.
In XaaS, "X" is a product that provides a service, just as your car does. But what's being sold is the outcome the user wants, which includes the convenience of not owning the product.
Cloud services are not necessarially
web services
though they may be web-based services.
