Why monolithic architectures are outperforming microservices for most teams

Short summary

The article argues that monolithic architectures outperform microservices for most teams, citing Prime Video's 90% cost reduction after consolidating a serverless setup into a monolith and Shopify's 2.8M-line monolith handling 32M requests/minute. Microservices impose hidden taxes: cloud data-transfer fees, sprint capacity lost to YAML and debugging, and resume-driven complexity. Companies like 37signals saved millions by leaving cloud entirely for owned hardware.

• •Prime Video cut infra costs 90% by moving from serverless to a monolith
• •Shopify runs a 2.8M-line monolith at 32M req/min using Packwerk for domain boundaries
• •37signals saved ~$10M over five years by buying Dell servers instead of using cloud
