This article mainly introduces the advantages and disadvantages of web distributed system architecture, the content is detailed and easy to understand, easy to operate, and has a certain reference value. I believe you will gain something after reading this article on the advantages and disadvantages of web distributed system architecture. Let's take a look.

A distributed system is a software system that supports distributed processing and is a system that executes tasks on a multiprocessor architecture interconnected by communication networks. It includes distributed operating system, distributed programming language and its compiler system, distributed file system, distributed database system and so on. Of course, these are also the key technologies of distribution.

The main ways to use distributed systems are:

1. Increase the system capacity. Our business volume is getting larger and larger, and in order to cope with the increasing business volume, the performance of one machine can no longer be satisfied, and we need multiple machines to cope with large-scale application scenarios. Therefore, we need to split the business system vertically or horizontally into a distributed architecture.

two。 The enhancement system is available. Our business is becoming more and more critical, and we need to improve the availability of the entire system architecture, which means that there can be no single point of failure in the architecture. In this way, the whole system will not become unavailable as a result of a machine failure. Therefore, it is necessary to use distributed architecture to redundant the system to eliminate single point of failure, so as to improve the availability of the system.

3. Because of modularity, system modules are more reused.

4. Because the software service module is split, the development and release speed can be faster in parallel.

5. The system is more scalable

6. The team collaboration process will also be improved.

There are three types of distributed systems:

1. Distributed processing, but only one master database, no local database

two。 Hierarchical processing, with each layer having its own database

3. In a fully distributed network, there is no central control part, and there can be a variety of contact ways between nodes, such as loose connection, tight connection, dynamic connection, broadcast notification connection and so on.

Then compare the advantages and disadvantages of a single application and a distributed architecture:

1. As can be seen from the table above, although the distributed system has some advantages, it also has some problems.

two。 The architecture design becomes complex (especially the distributed transactions)

3. Deploying a single service can be fast, but if multiple services are required for one deployment, deployment can become complex

4. The throughput of the system will be larger, but the response time will be longer.

5. The complexity of operation and maintenance will become very complex because there are more services.

6. Complex architecture leads to a larger learning curve

7. The complexity of testing and error checking increases

8. There are many kinds of technologies, which will bring complexity of maintenance and operation.

9. Managing services and scheduling in distributed systems becomes difficult and complex
