Cloud computing is the on-demand delivery...
of computing resources such as...
servers, storage, databases, networking,
applications and services over the Internet.
Cloud computing offers several benefits.
It eliminates the need for expensive infrastructure...
supported by technical teams...
and replaces it with a variable expense...
where you only pay for what you consume.
It provides quick access to vast amounts of computing resources,
saving on time...
and increasing the agility of the organization.
It allows businesses to scale elastically,
accessing resources to match...
the level of user demand as required,
leading to efficient capacity planning.
It offers better security and reliability...
since the cloud is regularly upgraded...
with the latest fast and efficient computing hardware.
Cloud computing falls into three broad categories.
With IaaS, you can quickly and easily provision...
full computing resources...
including processing, storage and networks.
With PaaS, you can get access to an on-demand environment...
for developing, testing, delivering and managing software applications.
With SaaS, you get on-demand access to software applications...
typically on a subscription basis...
without having to manage or control the underlying infrastructure.
There are three types of clouds.
A public cloud is owned, managed and operated...
by a cloud service provider...
with delivery of resources happening over the Internet.
A private cloud is used exclusively by a single organization...
with the services and infrastructure maintained on a private network.
A hybrid cloud uses a private cloud with strategic integration...
and use of public cloud services.
In short, cloud computing offers...
a quick, easy and cost effective access to computing resources...
that has revolutionized the way business is done.
