Reverse Proxy Node

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 this case, if you throw away the existing device to do a lot of hardware upgrades, this will cause the waste of existing resources, and if again ...

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.

Research on high concurrency key technology for public cloud storage and its system implementation the South University of south of the bridge first, this article describes two key technologies that can provide concurrent capability: Load balancing and reverse proxy caching. This paper takes LVs as an example to study the algorithms and working modes commonly used in load balancing, and briefly studies the implementation principle of reverse proxy caching. Secondly, we analyze and study OpenStack's object Storage Swift project, build a multi-node public cloud storage model based on load balancing, and increase the concurrency of the system by horizontally expanding the number of proxy nodes.

HBase as an open source implementation of BigTable, with the popularization of its application, more and more enterprises are applied to mass data system. This article will brief readers on the basics of Apache HBase and expand on IBM's HBase enhancements and extensions, HBase Master Multi-node high-availability support, and how to leverage IBM Biginsights for HBase in the IBM Hadoop cluster Service and job submission for monitoring and management. This article ...

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 ...

Translator: Alfredcheung on the topic of building high throughput Web applications, Nginx and Node.js are natural couples. They are all based on the event-driven model and are designed to easily break through the c10k bottlenecks of traditional Web servers such as Apache. Preset configurations can be highly concurrent, but there is still work to do if you want to do more than thousands of requests per second on inexpensive hardware. This article assumes that readers use Nginx's httpproxymodule for upstream node ....
