David Kimura PRO said about 1 year ago on AWS App Runner :
That would be my assumption. I'm not sure what the architecture is on the App Runner, but I would assume that it is a x86/amd64 CPU. I too am working on an Apple Silicon chip and whenever I deploy, I do need to take into consideration the difference in the chipsets. I normally catch any issues in my CI/CD (which runs on an Intel CPU) so it hasn't been too big of a deal here.
