The Design of the C++ Runtime for AWS Lambda
summary
Explains how the C++ runtime makes native code run reliably on AWS Lambda by bundling exact system libs and invoking the program through ld-linux.so with a controlled library path; dependency list comes from query the package manager so glibc and libstdc++ sets are complete, avoiding host conflicts. Shows bootstrap shell that unzips libraries, calls ld-linux, and runs the handler. Notes limits: dlopened libraries aren’t auto-packaged, TLS cert paths vary, adding glibc ~10 MB, and startup is reported fastest among runtimes.
