Low Latency Servers

Network latency has a significant impact on user satisfaction, and the physical distance between users and servers is the biggest factor in the latency problem. 　　Problems such as application and processing latency can always be solved by adding more computing resources, but long-distance data packets always take time (for example, from London to New York), which depends largely on the physical constants of the speed of light. Because most cloud computing providers are currently located in the United States, the problem of network latency in the American continent can be tolerated by users. But if your big one ...

The role of the CIO position has been changing. And with the rapid rise of large data, analytics and cloud computing, and the size of the data itself, it is no doubt that CIOs are given a new definition of responsibility by the pressures of it innovation and continued high and technical complexity. Businesses want the IT department to handle more business with less, and CIOs need to find a balance between budget and IT service spending, and all of the problems seem to have erupted at this point. At such a critical juncture, outstanding CIOs and CEOs have come forward to Sloan at MIT.

With the continuous improvement of server hardware performance in recent years, many SME users who pay more attention to price ratio have found that many low-cost rack-type servers can also meet the needs of their own server applications. And, http://www.aliyun.com/zixun/aggregation/32268.html "> survey shows that a lot of x86 server utilization is only 10%-15%, rather than the choice of high price servers in the engine room" idle ", It's better to choose the price than the better performance ...

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."

Tcl's founder, academician of the American Academy of Engineering, and ACM fellow John Ousterhout are currently teaching at Stanford University, and his main research projects in recent years have been ramcloud--memory clouds. As the name suggests, Ramcloud is such a new data center storage system, which is a large-scale system composed of thousands of ordinary server main memory, at any time, all information is stored in these fast dram (dynamic random access memory, commonly known as memory), Memory replaces the traditional system in the hard drive, the hard drive only ...

In today's era, solid-state hard disk has become a hot technology in the enterprise. But the computer science team at Stanford University thinks there is a better solution. They have come up with scalable and high-performance storage methods called Ramcloud. This solution can store all the data in dynamic random memory. You can also aggregate memory resources across the data center. The scalability and performance aspects of Ramcloud make it a key technology for high-performance computing. In particular, data-intensive applications, which are typically performed in compute-intensive applications. R ...

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 NoSQL database distributed special ...

In a 10-storey office in the east of Beijing's eastern third ring, a few 100 square meters of offices, a few more than 20-year-old boys sit in front of their computers, playing the famous game of World of Warcraft. It's not a matter of working hours, it's their job to debug the stability and latency of their newly developed cloud gaming platforms on a few configured computers. Dundee, the founder and CEO of the new company, Beijing Yun Lian Technology Co., Ltd., a few years ago, led the team to develop a ...

The hybrid flash array is superior in performance to an array based on traditional hard drives, with lower latency and cheaper prices than most pure flash arrays. However, their prices are still higher than those based on traditional hard disks, and their structures are much more complex. 　　Given the price and complexity, what kind of applications and environments can derive the most benefit from a hybrid flash array? First, let's look at the purpose of developing a Flash array: High data growth rates have had a huge impact on the data center. Analysis of this problem can start from "3V", namely: Volume (volume) 、...
