WHAT IS CLOUD COMPUTING?
In computers, we use the term cloud to represent a
network or internet. The term cloud is used for various
services like storage, servers, etc. Cloud computing is an
Internet-based service that helps users get the shared
resources, software, and information over a network on
demand. It also helps users store and access the data
and services. It is not required to install all the software
or resources for accessing them. We can use these services directly through a remote server and
web-based applications. The information and data can be accessed from anywhere at anytime.
BENEFITS OF CLOUD COMPUTING
Following are some benefits of cloud computing:
Easy Accessibility: Cloud services are available and accessible globally to everyone who has
a computer or any device with an Internet connection. No specialised hardware or software
is required.
Cost-effective: One has to pay minimal to no subscription charges to avail the services. It
saves us from buying expensive specialised hardware or software.
Flexibility: The services provided by cloud computing are available 24 hours a day and seven
days a week, and can also allow us to increase and decrease computing needs, hence,
providing users with the flexibility to work as per their requirements.
Shares Workload with User: The user’s computer is not burdened with different types of
software and programs, and the space required for software is lifted off the user’s memory.
HOW DOES CLOUD COMPUTING WORK?
Cloud computing can be divided into two sections: the front end and the back end. The Internet
is the link that joins both these ends. The front end belongs to the users/clients from where they
access the Internet for data, and the back end belongs to the cloud computing provider.
The front end includes computers, simple applications, and all means required to access the cloud
servers. The back end includes various applications and dedicated servers for each computer
program. This gap between the client and the cloud is then bridged by the Internet.
CLOUD STORAGE SERVICE PROVIDERS
Cloud computing provides a facility to store, organise and edit data through the network. The
data can also be shared with others using cloud storage. There are many service providers that
give the facility of cloud storage. Let us discuss some of them.
