Learn about cloud computing and its various uses,features and advantages.

3.  Cloud computing is providing different
facilities and amenities like databases,
servers, storage, applications, etc.,
through the Internet.
 Instead of storing data in local storage on
a hard drive, cloud computing helps us in
storing and saving data on a remote
database.
 Given that the device we are using has
access to the internet, it will have access
to the data as well.

5.  Cloud computing is so named because the
information and data that we are trying to
access are discovered remotely in the cloud,
which is nothing but virtual space.
 Users can store files, data, and applications
on remote servers and access this data with
the help of the Internet.

6. We have various functions that can be
achieved with the help of cloud computing
services, like:
 Email
 Storage, backup, and data recovery
 Scrutinizing data
 Building and testing apps
 Providing software on demand
 Audio and video streaming
 Working of cloud computing

8.  It is easy for users to come up with resources on demand
for nearly any type of application functionality; hence
there is no need for IT administrators to provide
resources.
 Organizations can scale up as requirements rise and scale
down as requirements fall. This reduces the investment
cost in infrastructure.
 It allows users to pay merely for the resources and
infrastructure they are using.

10.  There are three kinds of cloud deployments
or cloud computing architecture to choose
from for implementing our cloud services.
We could deploy these services on public,
private or a hybrid cloud.

11.  Public clouds are owned and maintained
by third-party providers of cloud service
that offer their resources like servers,
databases, and storage over the Internet.
Microsoft Azure and Salesforce are
examples of public clouds.
 By means of a public cloud, all the
infrastructure is managed by the third-
party cloud provider.

12.  A private cloud suggests that cloud
computing resources are being used
entirely by a single entity, either a
business or an organization.
 Physically, a private cloud is usually
located on the company site.
 The network used in a private cloud is a
private network that is responsible for
its services and infrastructure.

13.  A hybrid cloud uses elements from both the
public cloud and private cloud and combines
them, binding them with technology that
permits their data and applications to be
shared.
 By consenting data and applications to travel
between public and private clouds, a hybrid
cloud provides more flexibility,in turn
helping in optimizing the existing
infrastructure.

15.  Mainly, cloud computing services can be
infrastructure as a service (IaaS),
platform as a service (PaaS) and
software as a service (SaaS).

16.  Infrastructure as a service (IaaS) falls under
the simplest kind of cloud computing
service. In IaaS, we rent the IT infrastructure
that we need, like servers, databases,
storage, etc., from the cloud provider.
 A few examples of IaaS comprise of
Microsoft Azure and IBM Cloud.

17.  Platform as a service (PaaS) is a type of cloud
computing service that delivers a platform or
an environment on a demand basis to
develop, test and manage software
applications.
 It is one of the most complex cloud services.
A few examples of PaaS are Heroku and
Force.com.

18.  Software as a service (SaaS) is a cloud
computing service where we deliver
software applications to users over the
Internet on a subscription and demand
basis.
 With the aid of a web browser, users can
easily connect to the application over
the Internet.
