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 data storage, servers, etc. Cloud
computing is an Internet-based service that helps users to
access 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 remote servers 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 offloaded to the cloud, freeing
up local memory.
HOW DOES CLOUD COMPUTING WORK?
Cloud computing can be divided into two parts: front end and the back end. The Internet is the
link that joins both these ends. The front end includes the users/clients who access the data via
the Internet, while the back end consists of the cloud computing infrastructure maintained by the
cloud service provider.
The front end includes computers, user interfaces, and all the means required to access the cloud
servers. The back end includes various applications and the dedicated servers for each 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
offers cloud storage services.
