Cloud Computing Overview | What is Cloud Computing

Cloud Computing Overview

Cloud Computing provides us a means by which we can access the applications as utilities, over the
Internet. It allows us to create, configure, and customize applications online.

What is Cloud? Cloud Computing Overview!

The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is
present at remote location. Cloud can provide services over network, i.e., on public networks or on private
networks, i.e., WAN, LAN or VPN.
Applications such as e-mail, web conferencing, customer relationship management (CRM), ERP all run in cloud.

What is Cloud Computing? Cloud Computing Overview!

Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online
data storage, infrastructure and application.

We need not to install a piece of software on our local PC and this is how the cloud computing
overcomes platform dependency issues. Hence, the Cloud Computing is making our business
application mobile and collaborative.

Basic Concepts of cloud computing these below:

There are certain services and models working behind the scene making the cloud computing feasible and
accessible to end users. Following are the working models for cloud computing:

• Deployment Models
• Service Models

DEPLOYMENT MODELS :

Deployment models define the type of access to the cloud, i.e., how the cloud is located? Cloud can have any of
the four types of access: Public, Private, Hybrid and Community.

These are 4 types of Deployment Models below

• Public Cloud
• Private Cloud
• Hybrid Cloud
• Community Cloud

PUBLIC CLOUD

The Public Cloud allows systems and services to be easily accessible to the general public. Public cloud may be
less secure because of its openness, e.g., e-mail.

PRIVATE CLOUD

The Private Cloud allows systems and services to be accessible within an organization. It offers increased
security because of its private nature.

HYBRID CLOUD

The Hybrid Cloud is mixture of public and private cloud. However, the critical activities are performed using
private cloud while the non-critical activities are performed using public cloud

COMMUNITY CLOUD

The Community Cloud allows systems and services to be accessible by group of organizations.
