The design of large-scale websites mainly comes from huge users, high concurrent access and massive data . Once any simple business needs to deal with data counted by P and face hundreds of millions of users, the problem will become tricky, such as double The eleven large-scale spike activities and the actual combat of the B2B mall project will cause a series of problems, such as:
- Image server separation
- Database cluster and database table hash
- Cache
- Website mirroring
- Load balancing
- Storage problem
As network concepts and WEB technology become popular, various B2B, B2C, C2C and other e-commerce models are likely to be integrated into various large-scale commercial websites in a three-dimensional manner.
Therefore, as a company’s technical staff and as a “checkered jersey rider” who is in danger, how should we deal with the problems of massive storage, massive access , and massive information retrieval ?
For this question, Ali P8 gave us a detailed answer:
Although the business scenarios faced by each project are different, the design and optimization ideas are inseparable, and they have mastered the core technical points of high-concurrency system design ( caching, asynchronization, load balancing, queues, etc. ), and deepened themselves. The optimized design system will solve these business problems.

The document includes 101 core technical points of the high-performance framework of Alibaba's large-scale website , mainly including business design , message queues, concurrency, data structure, load balancing, current limit resolution, timeout retry mechanism, isolation, caching, connection pool thread pool , Asynchronous concurrency, expansion and splitting, queues, distributed architecture, implementation logic, etc...
Business design
Business design mainly includes a series of knowledge points of anti-weight design, idempotent design, process definition, status, background system operation feedback, and document annotation

data structure
The data structure contains core technical points such as stacks, queues, linked lists, hash tables, binary trees, red-black trees, etc., which are all important core technical points that must be mastered in the interview.
Load balancing
Current limit analysis
Timeout retry mechanism
isolation
Cache
Connection pool thread pool
Asynchronous concurrency
Expansion and split

Distributed architecture
Implementation logic
epilogue
A systematic high-performance framework learning plan is very important. Whether it is an interview or an advanced architect in the future, this is a bonus item, which can raise the chance of success in the interview to a higher level, so don't underestimate "it".
