I work on a very technically trivial service at a large company. It's the kind of thing that people run at home on a raspberry pi, docker container or linux server and it consumes almost no resources. But at our organization this needs to scale up to millions of users in an extremely reliable way. It turns out this is incredibly hard and expensive and takes a team of people and a bucket of money to pull it off correctly. When I tell people what I work on they only think about their tiny implementation of it, not the difficulty of doing it at an extreme scale.
