The article examines the hidden costs of microservices through case studies from Amazon Prime Video, Segment, Uber, and others, showing how distributed architectures multiply complexity, latency, and operational overhead. Companies like Shopify, Stack Overflow, and WhatsApp demonstrate that monoliths can scale to billions of requests with proper modular design. Evidence suggests microservices only produce positive returns for organizations with $10M+ revenue and 50+ engineers—below that threshold, the coordination costs exceed the benefits. ## Full article daily.dev links to this article rather than hosting it.
