Yup. At the last place I worked me and a colleague would joke that given the traffic our ecommerce platform actually had, we should be able to run the whole thing on a single Raspberry PI. I think he even ran some numbers on it. What we actually had was two containerized app servers and a separate large RDS instance and SES, SQS, SNS, ELB and all the other bits and pieces AWS buy in gets you. The cloud bills for the traffic we handled were ridiculous.
