Worship, Alibaba distributed system development and core principle analysis manual

#Foreword
With the increasing number of scenarios such as high concurrent access and massive data processing of large websites, how to achieve the goals of high availability, easy scalability, scalability, and security of the website is becoming more and more important.important.In order to solve such a series of problems, the architecture of large websites is also constantly evolving.To improve the high-availability architecture of large-scale websites, it is necessary to mention distributed.
In the book "Concept and Design of Distributed Systems", the following definitions are made for a distributed system:
A distributed system is a hardware or software component distributed on different network computers, and only communicated with each other throughMessaging system for communication and coordination

In simple terms, it is a collection of independent computers that provide services to the outside world, but to the users of the system, it is like a computer providing services.Distributed means that more ordinary computers (relative to expensive mainframes) can be used to form a distributed cluster to provide external services.The more computers, the more CPUs, memory, storage resources, etc., and the greater the amount of concurrent access that can be handled.
From the concept of distributed system, we know that the communication and coordination between various hosts are mainly carried out through the network, so the computers in the distributed system have almost no restrictions in space, and these computers may be placed in different cabinetsIt may also be deployed in different computer rooms, may also be in different cities, and may even be distributed in different countries and regions for large-scale websites.

Is the distributed system design concept difficult?(Anyway, the editor thinks it's difficult) Why don't you learn if it's difficult?This is not our style!When the demand comes, we have to implement it; how to get started with distributed systems and understand the design concept of distributed systems must be a problem that many developers have encountered.I would like to take this opportunity to recommend to you an Alibaba distributed system development and core principle analysis manual that I just came into contact with (strongly recommended, really fragrant).

The manual makes a comprehensive summary of the principles of distributed systems, and at the same time, it is supplemented by a large number of practical cases. You can easily get started with distributed systems with it.The manual is divided into two parts, with a total of 1015 pages. Below the space limit, I will only show you the catalog and part of the content.

Not much bb, look at the manual content:
