Cloud computing

English translation: cloud; cloud computing; cloud computer; cloud-based. The concept of "cloud computing" was proposed by Google. As the name suggests, this is a beautiful network application model. Cloud computing is the development of distributed processing (Distributed Computing), parallel processing (Parallel Computing) and grid computing (Grid Computing). It automatically splits huge computing processing programs into countless smaller subroutines through the network. , and then transfer the processing results to the user after calculation and analysis by a huge system composed of multiple servers. Through cloud computing technology, network service providers can process tens of millions or even billions of information within seconds, achieving network services as powerful as "supercomputers". Cloud can be a comprehensive name that unifies a series of resources such as hardware, software, and networks within a wide area network or a certain local area network. Quoting the definition from the Berkeley University Cloud Computing White Paper: Cloud computing includes application services on the Internet and the software and hardware facilities that provide these services in data centers. Application services on the Internet have always been called Software as a Service (SaaS), so we use this term. The software and hardware facilities of the data center are what we call the cloud.

Cloud storage

Cloud storage is a new concept that is extended and developed from the concept of cloud computing. In the era of cloud computing, you can abandon mobile devices such as USB flash drives. You only need to enter the Google Docs page, create a new document, edit the content, and then directly share the URL of the document with your friend or boss, who can directly open the browser to access the URL. We no longer have to worry about data loss due to damage to the PC hard drive.

Cloud security

Following cloud computing and cloud storage, cloud security also appeared. Cloud security is a concept created by Chinese enterprises and is unique in the international cloud computing field. The "Cloud Security" plan is the latest embodiment of information security in the Internet era. It integrates emerging technologies and concepts such as parallel processing, grid computing, and unknown virus behavior judgment, and uses a large number of meshed clients to monitor software behavior in the network. Abnormal monitoring, obtains the latest information on Trojans and malicious programs on the Internet, sends it to the server for automatic analysis and processing, and then distributes virus and Trojan solutions to each client. In the future, anti-virus software will not be able to effectively handle the increasing number of malicious programs. The main threat from the Internet is shifting from computer viruses to malicious programs and Trojans. Under such circumstances, the signature database identification method used is obviously outdated. After the application of cloud security technology, identifying and killing viruses no longer relies solely on the virus database in the local hard disk, but relies on huge network services for real-time collection, analysis, and processing. The entire Internet is a huge "anti-virus software". The more participants there are, the safer each participant will be, and the entire Internet will be safer. After the concept of cloud security was proposed, it caused widespread controversy, and many people thought it was a false proposition. But facts speak louder than words, and cloud security is developing like a gust of wind. Rising, Trend, Kaspersky, MCAFEE, SYMANTEC, Jiangmin Technology, PANDA, Kingsoft, 360 Security Guard, etc. have all launched cloud security solutions. The 2009 new product developed by Rising based on cloud security strategies intercepts millions of Trojan attacks every day, including more than 7.65 million attacks on January 8. Trend Micro Cloud Security has established five major data centers and tens of thousands of online servers around the world. It is reported that Cloud Security can support an average of 5.5 billion click queries every day, collect and analyze 250 million samples every day, and the first hit rate of the database can reach 99%. With cloud security, Trend Micro now blocks up to 10 million virus infections every day.
