Navigating The Scale: How Design Patterns Power LinkedIn’s Infrastructure
- Saira Khanum tl;dr: “We’ve found the Producer-Consumer pattern to be exceptionally effective in reaching these goals. This pattern has been successfully implemented in several of our core infrastructure systems, including the distributed server query system, server console monitoring, and network security monitoring. In this process, we have identified and built general solutions that are repeatable in similar environments, greatly improving engineering efficiency by leveraging proven methodologies.”featured in #567
Faster Continuous Integration Builds At Canva
tl;dr: In April 2022, the average time for a PR to pass continuous integration and merge into our main branch was around 80 minutes. As shown in the following diagram, we’re now getting our build times down below 30 minutes, as low as 15 minutes. This post shares what we’ve done to improve CI build times in our main code repository, including: (1) Finding the best opportunities (2) Experimentation (3) Deliver fast and incrementally (4) The importance of everyone’s contributions.featured in #537
Google Zanzibar For The Rest Of Us
- Greg Sarjeant tl;dr: Google Zanzibar powers authorization for hundreds of Google’s apps so you might think it's a great model for your authorization service. But does Zanzibar's promises of scale, high availability, strong consistency mean that it’s the right solution for the rest of us? Zanzibar's defining characteristic is actually centralization, which is a massive tradeoff that’s not practical for most. The Googles of the world can pull it off, but is there a Zanzibar for the rest of us?featured in #497

Switching Build Systems, Seamlessly
- Patrick Balestra tl;dr: Patrick chronicles Spotify's shift to Bazel. The move was driven by the need for a scalable build system for their growing codebase. The transition, which began in earnest in 2020, involved running two build systems side by side, adapting existing tools, and extensive testing. By 2023, the iOS Spotify app was fully built with Bazel, resulting in significant improvements in build times and developer experience.featured in #461
