DISCLAIMER: This is not a comment on Reddit’s future profitability or any reflection on the stock performance. This is a technical discussion on how a relatively simple link-aggreggator can be hosted, with the trade-offs. Reddit went public today. Its IPO document states1 that they use AWS and GCP. But I cannot find a break-down of infrastructure costs separately. That makes me wonder: what does the infrastructure costs of a pure link-aggreggator look like?
