Question

Define cloud computing​

Answer 1

Cloud is the software and databases that run on servers on the internet. Data centers throughout the world support cloud servers.

Since data can replicate at redundant sites on the cloud provider's network, cloud computing makes data backup, recovery, and continuity straightforward and less expensive.

The 3 primary types of cloud computing services:

Infrastructure as a Service (IaaS)

Platforms as a Service (PaaS)

Software as a Service (SaaS)

IaaS provides IT infrastructure to users over the internet.

PaaS provides software and hardware to software developers. PaaS enables users to create, manage, and run programs without needing to develop and maintain the infrastructure.

SaaS is a licensing model that enables subscription-based access to software through external servers.

Answer 2

Cloud computing is Internet-based computing where shared resources, software, and information are provided to devices and computers on demand. (pay-for-what-you-use model)

ex. servers, storage, databases, networking, software, analytics, and intelligence
