AWS

“AWS is defensible across nearly every moat. Physical infrastructure (data centers, hardware, global footprint) cannot be replicated by an LLM. Regulatory compliance (FedRAMP, HIPAA, PCI-DSS certifications) are real barriers. Network effects are massive — enterprises are locked in by integrations, team expertise, and ecosystem lock-in. Proprietary data on infrastructure performance, customer patterns, and service reliability compounds daily. The coordination layer (IAM, VPC, service orchestration) requires actual infrastructure, not just reasoning. An LLM can suggest what to build; AWS actually builds and runs it. The only replaceable pieces are advisory and documentation — the core value is execution.”
