A company runs code on AWS Lambda. Compared with running the same code on an EC2 instance, how does the customer's responsibility change?
With Lambda, AWS manages the operating system and server infrastructure, so the customer's responsibility narrows to their code, its permissions, and its data. Hardware patching, physical servers, and network backbone are always AWS responsibilities.
