Definitin
“Cloud Application” is a subset of “cloud computing”, and the reflection of cloud computing technology in application layer. Its biggest difference with cloud computing is that, cloud computing has its existence as a concept of macro technology, while cloud application is a general name of cloud computing products aimed to solving practical problems for customers directly.

Principle
The operating principle of cloud application is to create a completely new application service which can be adopted immediately by transferring the local software installation and operation. This new application can complete logic operation or computing tasks through controlling remote server clusters via the connection of LAN or public networks. Finally realized through internet technology, “Cloud application” is represented in Thin Client or Smart Client, and its interface is the integration of HTML5，Javascript，or Flash technologies. Cloud application can not only help customers to cut down IT cost, but also largely improve work efficiency. Therefore, the transformation of traditional software to cloud application has become an irresistible trend which will be soon all the rage.
