Redis Implement distributed lock In the cluster and other multiple servers often used to synchronize the business, then the ordinary transaction is to meet the needs of the business, the need for distributed locks. Distributed locks are implemented in a variety of ways, such as redis implementation of distributed lock

With the development and popularization of network, especially the rapid development and popularization of Internet application, network security has been paid more and more attention by users at all levels. People in the enjoyment of the many benefits of information, but also faced with the increasingly prominent issues of security. For example: the protection of state secrets and trade secrets in the network environment, in particular, the government after the Internet to protect sensitive inf

"Abstract" in this paper, a two-tier distributed database architecture is established by introducing the memory database layer. This scheme is used to solve the problem of data storage and access in massive and high concurrency systems, especially for the complex and complex Internet stations of electronic commerce and other data models. These years the Internet station develops rapidly, in order to deal with the high concurrent access under the massi

This project is also a first glimpse into the Python crawler project, is also my graduation design, at that time, found that most people choose is the site class, it is common but, are some simple additions and deletions, business class to feel a very common system design, at that time also just in the know to see an answer , how do you use computer technology to solve the practical problems of life, links are not put, interested can search, and then use this topic. Abstract: Based on the Python

Label:Creating a horizontal distributed database requires a two-step implementation: dividing subsets and working with subsets. The advantage of distributed database is that the IO is dispersed, so it is easy to read the data quickly and disadvantage is to consume a lot of network bandwidth resources. Dividing a subset is to divide the original table horizontally into several smaller member tables, each of

This algorithm is considered to be the most effective in similar algorithms.Chinese namePaxos al

Introduction to Distributed File Systems 1. The origin of the story Or many years ago, I had a small system, a small system related to payment. Because it is a small system, everything is so simple. An application server and a database server. Files and images are stored on the application server. Everything is so plain that everything is taken for granted. Suddenly one day, payment became a fashionable topic. suddenly one day, the platform was about

In DOTNET Enterprise Architecture Application practices a few days ago-the history and development of enterprise management software architecture (Computing) (I, this section describes the host-terminal structure, client-server structure, and browser-server structure in the release of enterprise management software architecture. This article introduces you to the distributed computing and SOA architecture. Generalized

Open source has become the basic principle of some large web sites. And as these sites grow, some of the best practices and rules appear in their structure. The purpose of this paper is to introduce some key problems in the design of large web sites and the basic work to achieve them.This article focuses on the introduction of network systems, although some of the guidelines are also applicable in other distributed systems.1.1. Design principles for W

In the first part of "Designing Data-intensive Applications" (see above), the basic theory and knowledge of the data system are introduced, all based on single node. In the second part of the Ddia (distributed data), the field of view is extended to the distributed Data system. There are three main reasons for the distribution of data: Scalability Fault Tolerance/high Availability Reduce Latenc

I've heard of it. Distributed due to the need to find jobs so learning, all know that there are distributed clusters (hdoop), distributed Storage (GFS,NFS), distributed Database (hbase,redis,memcaced), distributed systems, distributed
