Differences between clusters and Distributed Systems The difference between clusters and distributed systems. Cluster: A cluster is a group of service entities that work collaboratively to provide a service platform that is more scalable and available than a single service entity. In the client's view, a cluster is lik

Introduction"Theory advanced in Distributed Systems-Paxos" introduces the consistency protocol Paxos, today we will learn two other common consistency protocols--raft and Zab. By comparing with Paxos, we understand the core ideas of raft and Zab and deepen the understanding of conformance agreements.RaftPaxos is biased toward theory, which mentions less about how to apply to engineering practice. The diffic

IntroductionIn distributed systems, time is a huge problem, because there will be their own physical time on different computers, and how to achieve the consistency of state affairs is often difficult. The lack of a global physical time makes it difficult to find out how the state of execution of a distributed program is.clock, event, process state, and time sync

1 purpose of process migration One of the characteristics of distributed systems is to allow information to move through the system, but some systems only allow data (files, database records, etc.) to migrate in the system, and some systems allow only those tasks that have not yet started to be migrated, some

all levels of the distributed system, single database system, and even memory variables.Scenario 1: high read response speed requirements There is a type of system that is frequently updated and requires high read response speeds, such as stock trading systems. Under the lock mechanism, write will block read, so when there is a write operation, the response speed of the read operation will be affected; whi

When I first saw the first version of this book, it seemed like it was in, and I was shocked when I remembered it. I was able to reach this level as a teaching material for my undergraduate sophomore year, and I also got in touch with a lot of content for the first time, I was very ashamed. Later, I spent some time studying it carefully. Unfortunately, there were no specific experiments on many important points. At that time, I felt that this

This past weekend I read Joe Armstrong's paper on the history of Erlang. Now, HOPL papers in general is like Candy for me, and this one does not disappoint. There ' s more in this paper that I can cover in one post, so today I ' m going to concentrate on one particular feature of Er Lang highlighted by Armstrong.Although Erlang is designed to encourage/facilitate a massively parallel programming style, it error handling may be even More noteworthy. Like everything else in Erlang, it error handli

These two methods have some drawbacks, reference: Lease mechanism IntroductionTherefore, a lease mechanism can be introduced. During the lease term, you can ensure that the data cached by the client is up-to-date. When the lease expires, the client needs to re-ask the server for data and renew it.Definition of Lease: A lease is a

A brief introduction to XML-RPC, SOAP, REST Three Web service implementations and RPC, message, Resource three kinds of patterns.Web Service Implementation Scenarios There are three major Web services implementations, because XML-RPC is gradually replaced by soap, so it can be said that the mainstream Web services implementation is only REST and SOAP two kinds.

Distributed File System1. the increasing volume of data, which cannot be stored in a range of operating system jurisdictions, is allocated to more operating system-managed disks, but is not easily managed and maintained, so a system is urgently needed to manage the files on multiple machines, resulting in a distributed file system.2. It is a file system that allows files to be shared across multiple hosts o
