What is Cloud Computing ?
Cloud computing is
the delivery of different services through the Internet. These resources
include tools and applications like data storage, servers, databases,
networking, and software.
Cloud computing is
a popular option for people and businesses for a number of reasons including
cost savings, increased productivity, speed and efficiency, performance, and
security
Cloud Computing
takes the technology, services and applications to those on the Internet and
turns then into a self-service utility. Cloud sever are located in data centers
all over the world. Using cloud computing, users and companies don't have to
manage physical servers themselves or run software application on their own
machines.
The cloud enables
users to access the same files and applications from almost any device, because
the computing and storage takes place on servers in a data center, instead of
locally on the user device. This is why a user can log into their Instagram
account on a new phone after their old phone breaks and still find their old
account in place, with all their photos, videos, and conversation history. It
works same for Facebook also, and any social accounts. It works the same way
with cloud email providers like Gmail or Microsoft Office 365, and with cloud
storage providers like Dropbox, Google Drive or Google photos.
Cloud Computing
Services:
There are three
types are as follows-
1.Software as a Service (SaaS)
A
vendor provides clients pay as you go access to storage network, operating
system, servers and other computing resources in cloud. Organisation use their
own platforms and application within a service provider infrastructure instead
of purchasing hardware users pay for IaaS on demand. Infrastructure id scalable
depending on processing and storage needs.
2.Platform
as a Service (PaaS)
It
provides users with cloud environment in which they can develop, manage and
deliver application to provide platform with tools to test and host application
in some environment. It facilitates collaborative work even if team works
remotely.
3.Infrastructure
as a Service (IaaS)
It
is cloud computing that provides users with access to vendors cloud based
software. Data is secure in cloud, equipment failure does not result in loss of
data application are accessible from at most any internet connected device
virtually from anywhere in cloud.

google cloud service. Azure (the service) is a competitor to AWS Windows Azure
Platform is a competitor to Google’s App Engine.
Google
