Your system worked fine at a thousand users. Then it didn't. Software Architecture Insights is Lee Atchison's podcast about building software that holds up. Scaling, availability, cloud cost, and what AI is doing to how we build. Most episodes run about 15 minutes. Lee takes an idea from his weekly newsletter and goes further than the article could. Sometimes he revisits an old call to see how it aged. Sometimes he talks with someone doing the work. Lee Atchison is a software architect and author who helps companies architect and operate AI-powered SaaS at scale. He wrote Architecting for Scale (O'Reilly) and The Software Conductor, and writes for architects, engineers, and the leaders who depend on them. Get the newsletter at softwarearchitectureinsights.com.
