The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...

Statistics show that China's printing industry for the first time 2013 output value exceeded 1 trillion yuan, up to 1,039,850,000,000 yuan. Why does the printing of such a large plate not have a vertical electric commodity card that is so loud? The article will be discussed from 5 aspects. China's vertical electric business industry in the 2014 is still in the ascendant. Under the trend, some enterprises began to break through the siege to open up new Horizons, and some began to gradually exit the market. Because the vertical electric business has pays attention to the industry brand, the depth service as well as the channel specialization and so on the superiority, enables it to be independent in the existing large-scale electric business platform to grow and develop unceasingly. We are used to ...

This article describes how to build a virtual application pattern that implements the automatic extension of the http://www.aliyun.com/zixun/aggregation/12423.html "> virtual system Pattern Instance nodes." This technology utilizes virtual application mode policies, monitoring frameworks, and virtual system patterns to clone APIs. The virtual system mode (VSP) model defines the cloud workload as a middleware mirroring topology. The VSP middleware workload topology can have one or more virtual mirrors ...

Absrtact: About Lenovo using the public-chip model to do the PC brand small new discussion is continuing to ferment, it is seen by some people as Lenovo to the Internet thinking of the study of water test. A participant in the project, Lenovo staff to the sharp observation that this product and the public-chip mode is not related to Lenovo's use of public-chip model to do the PC brand "small new" discussion is continuing to ferment, it is considered by some people as Lenovo to the Internet thinking of the test water. A Lenovo employee involved in the project said to the sharp observation that this product and the public-chip model is irrelevant, but only a coincidence of time, but small new system ...

Domestic about Cassandra more detailed information or too little, the following is based on some foreign data translation summary of the content, we have the need to refer to the reference! Not finished, I will write side upload! When planning a Cassandra cluster deployment in a formal production environment, you must first consider the amount of data that you plan to store, as well as the load (read/write) pressure of the main front-end application system and extreme conditions. Hardware selection: For any application system, reasonable hardware resources ...

Often see people talking about cloud storage, but without seeing the actual figure, it's hard to imagine what cloud storage looks like, and here's a simple architecture diagram of a cloud storage. The Orange storage node (storage node) is responsible for storing files, and the blue Control node is indexed as a file and is responsible for monitoring the balance of capacity and load between storage nodes, which together form a cloud storage. Storage node and control node are simple servers, just storage node of the hard disk more, storage node server ...

Why the more prosperous and developed cities, people's survival pressure, and in poor and backward rural areas, people's survival pressure is very small, this is determined by the inherent rules of the wealth system, not because of people's subjective desire to change. 　　For example, if the United States wants to really solve the economic crisis under the bustling imagery, it needs to really understand the human wealth system and fundamentally find a solution to the crisis.
