>so in some sense, Slack is paying AWS a premium to not pay them for unneeded resources at 3:30 AM. If you're running a server for 1/3 of the day (8 hours), you're probably better off using dedicated instance (60% discount with 3 year reservation) than trying to optimize around on-demand instances (66% discount with perfect allocation, ignoring the engineering cost). The economics are even worse if you consider imperfect allocation, or consider self-hosting (probably cheaper if you're as big as slack). |
