Cloud computing is the on-demand delivery of computing resources like servers, storage, databases, networking, software and analytics over the internet. It provides advantages like on-demand self-service, broad network access, resource pooling, rapid elasticity and pay-as-you-go pricing. Major cloud providers like Amazon Web Services (AWS) offer infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Large companies like DBS Bank, Grab and Netflix leverage AWS's capabilities for tasks like hosting web services, matching drivers to passengers efficiently and video transcoding.

9. What is Cloud Computing .?
Cloud computing is the on-demand delivery of IT
resources over the Internet with pay-as-you-go
pricing.
Instead of buying, owning and maintaining
physical data centers and servers, you can access
technology services, such as computing power,
storage and databases, on an as-needed basis
from a public cloud provider, like Amazon Web
Services (AWS)

10. What is Cloud Computing ... ?
And what if you needs to change?
You have to go through the time, effort and cost
required to change, upgrade all of the above.
Software is flexible
If your needs change, your software can re-
configure much more quickly, easily and cost
effectively than the hardware.
