Need for Async - In Pursuit of Internet-Scale Apps
Explore the critical need for asynchronous programming in developing high-performance, internet-scale applications in this comprehensive talk. Dive deep into the underlying reasons and techniques used to achieve scalability, from kernel-level intricacies to high-level abstractions. Begin with an examination of network transports and their impact on system latency, then progress to operating system socket selector implementations and the famous C10K problem. Discover how these implementations evolved to handle increasing numbers of concurrent connections. Analyze processor and thread utilization effects, and learn how parallel programming paradigms like message-passing and stream processing contribute to achieving stable, low-latency systems. Gain valuable insights into the pursuit of optimal performance for modern web applications.
