Cloud Computing

Introduction
Cloud computing is an advanced technology
in the field of computer science
It is a kind of process to transfer information
technology services by using internet and
web based servers
There are main three parts of cloud

Increase performance of mobile devices
Reduced cyber-attacks
Very cheap and easy to understand
Consumers can use this process as a backup
plan [1].

Disadvantages of cloud computing
Very expansive process
Limited resources
Increased security risks and threats
Very complex to design
Users can lose their private details
Vulnerability to attack [2].

Applications
