Updated: An introduction to cloud computing right from the basics up to IaaS and PaaS, hybrid, public, and private cloud.
Cloud computing is a system that combines a large number of computer resources and high-level services. It relies on the sharing of different resources.
the appearance of cloud computing may rise some concerns about the privacy protection.Ā Cloud computing is based on an existing distributed network, where every computer can be considered as a node. When a computer is connected to the Internet, it becomes part of the Internet. Without effective security protection, every computer in the "cloud" can access other nodes through certain means. For example, some commercial companies use coolies to spy on the activities and web pages when users surf the Internet. Also, by using the āTrojan horse programā, the hackers canĀ control Ā other computers and in doing so, they can know what services users are using in the cloud, etc. It can be said that any operation of the user will leave traces on his computer, and can be obtained through a certain way.
Privacy protection is a great challenge for the development of cloud computing. In fact, it is far from enough to protect the right of privacy by a single means. A complete system is needed, involving multiple levels.
