In Memory Database Cluster

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

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 ...

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

MapReduce: Simple data processing on large cluster

Translation: Esri Lucas The first paper on the Spark framework published by Matei, from the University of California, AMP Lab, is limited to my English proficiency, so there must be a lot of mistakes in translation, please find the wrong direct contact with me, thanks. (in parentheses, the italic part is my own interpretation) Summary: MapReduce and its various variants, conducted on a commercial cluster on a large scale ...

Using the latest 4, 8-way IA server architecture of High-performance server cluster system, the use of the leading VI (Visual Interface) technology, effectively eliminates the communication bottleneck between nodes in the system, and the system uses load balancing technology so that user equipment can be fully utilized,    and achieves 4 9 reliability, has the extremely high product price-performance ratio, provides a strong database server platform for the Internet application. ...

Today's world is a large data age of the information world, our life, whether life, work, learning are inseparable from the support of information systems. The database is the place behind the information system for saving and processing the final result. 　　Therefore, the database system becomes particularly important, which means that if the database is facing problems, it means that the entire application system will also face challenges, resulting in serious losses and consequences. Now the word "Big Data age" has become very popular, although it is unclear how the concept landed. But what is certain is that as the internet of things 、...

With the advent of cloud computing, there are many new nouns, such as cloud database, cloud storage, elastic expansion, resource isolation and so on. 　　The following is the hot "shared database" for everyone to explain what is called "shared database". I introduce myself first, I am engaged in IT industry 10, was an architect many years ago. 　　Below is a personal experience, as well as with some Google, BAT, Jingdong and other companies cloud computing architects to get the summary of the experience, for you to analyze what is a "shared database." What is shared data ...

I first http://www.aliyun.com/zixun/aggregation/7415.html "> Self-introduction, I engaged in IT industry 10, years ago is an architect, now in an internet company as product manager, below is personal experience , as well as with some cloud computing architects to exchange the experience of the summary, the following on the Beijing-East Cloud Database For example, there are improper please forgive me. What is a shared database talking about "shared database", what puzzles us most is "...
