Introduction: the basic architecture adopted by B2B Mall and C2C Mall before is conventional: a load balancer back-end two web clusters plus a database server (average daily PV3~ 50, 000). The overall visit volume is not large, and the failure rate is not high. Business is only occasionally affected by sql query deadlocks.

Detailed explanation of the principle: divided into the following parts: first, security and monitoring 2, customer self-built application 3, background database 4, distributed service 5, storage

Module details:

Security and monitoring: security choice Aliyun comes with three free products: green net security, cloud shield and situational awareness, among which a high-defense fortress machine is always required (usually the high-defense machine in the IDC computer room, Aliyun high-defense IP is too expensive)

Customer-built applications: for e-commerce platforms, users generally build self-built applications include customer management center, commodity management center, marketing management center, order management center, points management center, store management center, payment, customer service, financial before the company mall has customer management center, commodity management center, order management center, points management center, store management center, payment, customer service, finance. In principle, the above modules should be written separately and placed in the elastic computing cloud. Because of the small number of visits, we write all the modules together and run them in flexible computing. One of the advantages of using Aliyun is that you don't need to worry too much about capacity expansion. In many cases, flexible expansion is very convenient, and such efficiency is not available in the traditional IDC computer room.

Background database: the background database uses a self-built SQL server database. You can consider the traditional expansion of the database (master-slave)

Distributed services: generally message services, I am not very clear about the application of message services, basically only at the deployment and maintenance level, later to strengthen the control of message services

Storage: using object OSS for file management

The architecture solution is (refer to the document Retail e-commerce architecture .vsdx):
