The 2011 Cloud Computing Development Outlook survey, released by three Open-source cloud service providers cloud.com, Bitnami and Zenoss, shows that open source software is becoming increasingly dominant in the cloud computing world. The survey noted that in all of the cloud deployments they surveyed, there were only 3% cloud projects that did not use open source software at all, and 69% of cloud projects used Open-source software where possible. The above figure is a number of important data extracted from the survey. For the open source community, other important data is that there are still 5 ...

Public cloud computing was once popular in the IT world. In the 2010, the industry's focus went to the private cloud after it people expressed concern about the security of the public cloud. At present, because everyone wants to require the flexibility of the operation, the hybrid cloud will naturally enter people's view. The results of several recent cloud computing surveys have also confirmed the growing interest in mixed clouds. The Unisys survey, conducted in 2010, found that 21% of IT organizations were focusing on the hybrid cloud, while a 2010 Sand Hill group had more than 500 IT managers ...

Once upon a time, those familiar with the name of the program hero gradually away from us. With the advent of Windows and the Internet era, the strength of the individual has become increasingly small. Just as we were beginning to believe that the era of singles was gone, cloud computing was born. Its powerful computing power, storage capabilities, and simple and efficient programming interfaces make it easy for a programmer to manipulate thousands of computers without having to worry about too much detail. The age of cloud computing seems to make us feel the personal hero of our time. The fading of the program Hero era WP ...

The Facebook company unveiled the memcached performance test file in a recent International Green Computing Conference in Orlando, Florida, where TILEPRO64 processors, Intel Xeon processors and AMD The Opteron processor's standard server performs performance testing. Tilera, Seamicro and Calxeda have been selling Hadoop's massive data and memcached Web caching as a marketing point to promote their own micro-server products, but when it comes to distributed ...

Introduction Cloud Computing (Cloud Computing) is an internet-based Super computing model in which thousands of computers and servers are connected to a cloud of computers in remote data centers. The user uses the computer, the notebook, the handset and so on the way to pick up the data center, according to own demand carries on the computation. There is still no universally agreed definition of cloud computing. Combined with the above definition, we can sum up some essential features of cloud computing, that is, distributed computing and storage characteristics, high scalability, user-friendly, good management. 1 Cloud storage schema orange as storage node (Sto ...)

From the Institute of Software Research, Chinese Academy of Sciences, National Engineering Research Center system security and Trusted computing, Ms. Ding Liping for you to share "cloud computing environment covert channel analysis." 　　She described in detail the three aspects of covert channels, security threats and covert channels in cloud computing environments, and their work. ▲ Software Institute of Chinese Academy of Sciences the concept of covert channel covert channel at operating system level refers to the way that malicious process realizes information leakage through collusion information system (Ding Liping), and the covert channel analysis is the security standard at home and abroad.

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

We have all heard the following predictions: By 2020, the amount of data stored electronically in the world will reach 35ZB, which is 40 times times the world's reserves in 2009. At the end of 2010, according to IDC, global data volumes have reached 1.2 million PB, or 1.2ZB. If you burn the data on a DVD, you can stack the DVDs from the Earth to the moon and back (about 240,000 miles one way). For those who are apt to worry about the sky, such a large number may be unknown, indicating the coming of the end of the world. To ...

We should understand that cloud computing is not just a collection of services provided by business entities. Instead, from a security standpoint, cloud computing is just a single, interoperable system designed to provide interdependent subsystems that provide a specific combination of on-demand services across multiple entities. Therefore, for this understanding, we define a system of "a set of interacting or interdependent components that form a complete whole" and a "set of subsystems that contain separate but interrelated elements of a unified whole." In short, they provide the service either voluntarily or involuntarily. However, improving our cloud computing ...
