Cloud Computing is just a newspeak way of redefining pre-existing concepts and turning them into a botnet. Look at the terms with me:
Infrastructure as a service (IaaS):
Wikipedia definition:
"Infrastructure as a service" (IaaS) refers to online services that provide high-level APIs used to dereference various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup etc.
So it's literally just a CDN.
Platform as a service (PaaS)
NIST Definition:
The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.
So it's literally an online library.
Software as a service (SaaS) (GNU Prefered: SaaSS, Service as a Software Substitute)
NIST Definition:
The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
This is the equivalent to a limited loan shell. DaaS (Desktop as a Service) is word-for-word a full Loan Shell.
There are three newer-forms of the Cloud-Computing platform which are cancer that a person in the field couldn't even explain to me. It is all newspeak, redefining terms, and making buzzwords for the computer illiterate and the idiot millennial "Web Dev" to latch on-to proprietary services.
