Write in front

Many companies are now resuming work one after another, and many programmers have to catch the small tail of Yinsi, but if the technology is not related to everything, it is in vain, and the home has compiled a core technology of a hundred million traffic website architecture. It covers a lot of knowledge points such as high availability, high concurrency, isolation, current limiting, load balancing and reverse proxy, multi-level cache, application-level cache, HTTP cache, cases, and how to expand capacity . Today I will share with you, I hope it will be useful to you.

Talk to Alibaba P7 architect about the core architecture of 100 million-level traffic, build a high availability and high concurrency system

This book is divided into four parts: overview, high availability principle, high concurrency principle, case study, from load balancing, current limiting, downgrade, isolation, timeout and retry, rollback mechanism, pressure test and plan, caching, pooling, Asynchronization, capacity expansion, queues, etc., the core technology of the billion-level traffic website is introduced in detail, so that readers can quickly apply it in practice after reading it.
