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 ...

Recently a series of pre-sales demos of Microsoft Virtualization Solutions in fact, for most customers will not be a complete set of "relatively perfect" program in the first time to see very in-depth, but usually more care about some of the most basic functions and configuration options, especially the technical post people will often have "preconceived" mood, This is normal, assuming that the customer is using n years of VMware or that he is a Si jie powder, then you have a Microsoft environment to speak to others, the other party will ask some Hyper-V ...

Apache Hadoop is now widely adopted by organizations as the industry standard for MapReduce implementations, and the Savanna project is designed to allow users to run and manage Hadoop over OpenStack. Amazon has been providing Hadoop services over EMR (Elastic MapReduce) for years. Savanna needed information from users to build clusters such as Hadoop's version, cluster topology, node hardware details, and some other information. In mentioning ...

Network Load Balancing allows you to propagate incoming requests to up to 32 servers that can use up to 32 servers to share external network request services. Network Load Balancing technology ensures that they can respond quickly even in heavy loads. Network Load Balancing must provide only one IP address (or domain name) externally. 　　If one or more servers in Network Load Balancing are unavailable, the service is not interrupted. Network Load Balancing is automatically detected when the server is unavailable, and can be quickly in the remaining ...

This issue will be discussed in the following two topics: 1. Wave released 5 Smartrack new products, pointing to the integration of the architecture market, 2.VMware upgrade NSX expansion users, the latest vsphere 6 also full of confidence! So many sound column links: http://voice.zdnet.com.cn/2015/0206/3046088.shtml guests point of view refining: "00:00" Wave released 5 Smartrack new products, pointing to the integration of the architecture market this wave released in fact, the main ...

After more than eight years of practice, from Taobao's collection business to today to support all of Alipay's core business, and in the annual "Double Eleven Singles Day" continue to create a world record for the transaction database peak processing capacity.

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 ...

Hadoop is a highly scalable, large data application that can handle dozens of TB to hundreds of PB of data through fewer than thousands of interconnected servers. This reference design realizes a single cabinet of Hadoop cluster design, if users need more than one cabinet of Hadoop cluster, can expand the design of the number of servers and network bandwidth easy to achieve expansion. Hadoop solution The features of Hadoop design Hadoop is a low-cost and highly scalable large data place ...

Vsphere Big Data Extensions (BDE) supports multiple deployments to build Hadoop clusters. By: Store/COMPUTE binding model: Deploy Storage nodes (Data node) and compute nodes (Task Tracker) in the same virtual machine. 　　This is the most straightforward and simple deployment model that can be used to validate concepts and carry out data processing tasks for small-scale clusters. Single Computing model: Deploy only COMPUTE nodes (Job Tracker and task Tracker) ...
