The Problem I run a production SaaS on AWS Lambda (Python 3.12, 7 source files, boto3 + MCP dependencies). All functions on x86_64. AWS Graviton2 offers 20% cheaper duration charges — but switching without verifying ARM64 compatibility is risky. The manual audit process: Check every pip dependency for native C extensions Verify no inline assembly or architecture-specific intrinsics Confirm container base images support linux/arm64 Cross-reference AWS docs for runtime support For a small codebase, this takes a few hours. For larger projects with numpy, pandas, or compiled extensions — days. The Setup: Kiro Web + Graviton Migration Power Kiro Web is AWS's agentic IDE in public preview. It runs an autonomous agent in a remote sandbox with Docker support, MCP servers, and installable "Powers" (domain- specific tool packages).…
