After posting the article "a sns strategic casual game development Note 01-Distributed System Logical Architecture Design ()", I was very happy to receive some bloggers, in addition, some friends enthusiastically gave some suggestions: @ Phantaci.com: "We recommend that you design a DB front-end. The DB front-end is used to connect multiple databases of the game. The DB front-end is a data access proxy serv

Abstract: With the development of the motherland's modernization, the construction of new urban transportation-underground railway is in the ascendant. With the continuous development of automation technology, the centralized control and management of subway mechanical and electrical equipment, especially the environmental control equipment, provides the possibility for the scientific and efficient operatio

Ganglia: distributed monitoring system 1. Environment installation and configuration1.1 dependent Software Download Ganglia is a cluster monitoring software developed by Berkeley. Monitors and displays various status information of nodes in the cluster, such as cpu, mem, hard disk utilization, I/O load, and network traffic, historical data can also be displayed on the php page in a curve. Ganglia depends on

Baidu's high-performance computing system (mainly backend data training and computing) currently has 4000 nodes, more than 10 clusters, and the largest cluster Scale is more than 1000 nodes. Each node consists of 8-core CPU, 16 GB memory, and 12 TB hard disk. The daily data volume is more than 3 PB. The planned architecture will have more than 10 thousand nodes, and the daily data volume will exceed 10 pb.The underlying computing resource management l

Ansible Getting Started experience What does Ansible do? Why does it need to be used in a distributed system?If I have a Java service a now, you can deploy only one server when the volume of traffic is small and availability requirements are not high. When service A to launch online, you can log in directly to the server to publish work. But because of the growth in business volume and the need for availab

This article is a note of a speech by Google Academician Jeff Dean at this year's socc conference. It mainly introduces some models used to design distributed systems, the video address of this speech (Silverlight needs to be installed ). Splitting a large and complex system into multiple services with as few dependencies as possible helps test, deployment, and independent development by small teams

There is a single point of failure for the centralized algorithm, so let's take a look at the non-centralized algorithm.Assuming that a copy of the shared resource is replicated n times, each copy has its own collaborator control access, and if a process is to access the shared resource, it is primarily M>N/2 to allow the co-authors to vote.1, if process 0 is to initiate access requests, only 5 of the 8 collaborators (including themselves) are allowed
