Reliability

The previous chapters have described the underlying technologies such as consistent hashing, ID generator, and now using these techniques we can develop a URL shortener that can generate 100 million URLs per day. Design consists of the following elements: API endpoints URL redirecting URL shortening Data model Hash functions: Hash + collision resolution vs Base-62 conversion Additional topics to consider: Rate limiter Web server scaling Database scaling Analytics Availability, consistency, and reliability These items are disclosed in a very interesting Chapter 8 of the book:

Earlier this year the book club of our company has studied excellent book: Martin Kleppmann - Designing Data-Intensive Applications This is the best book I have read about building complex scalable software systems. 💪 As usually (to better learn) I prepared an overview and mind-map. Chapter 1: Building blocks of the apps What is Reliability, Scalability and Maintainability. Examples and definitions. Faults and Failures Performance, Load, Latency and Response Time Operability, Simplicity, Evolvability Why you should randomly kill your servers 😅 How Twitter delivers 12,000 tweets per second to 300,000 readers per second.
