Gotcha. On this forum we've guessed what Tesla can and can't do before and been very wrong. Very related, it used to be said that Tesla couldn't enable Model 3 passive entry with the key fob since it doesn't have the necessary hardware. That turned out to be completely wrong and we were just handing them excuses. (It did require new key fob hardware, but nothing on the car). My understanding is that the bulk of the power usage when awake is the AP computer. It could need to be on for some reason, but the car also operates perfectly fine without it (it has to in case that system faults - it's not a critical component). In this regard I don't think anyone here is being a petulant child - expectations are absolutely reasonable on such an expensive purchase. I don't see anything unreasonable about expecting my car to be able to open at a moment's notice while also using minimal power, and have remote access capability. ICE vehicles have done this for years (and had to with much smaller batteries), why not the "leader" of EVs?
I've done work in SaaS too. Keeping resources hot is indeed absolutely part of it, and those resources will be under-utilized (if at all). I incredibly highly doubt those are in a busy-wait state though, consuming maximum CPU power. They are allocated, provisioned, and available, but in a reduced power state if not being actively used. Someone the size of Instagram is also definitely mindful of load patterns and will be optimising for cost for sure (and thus optimising their portion of power usage, directly or indirectly). To be perfectly truthful I don't know how the numbers compare to, say, my personal computer. But "idle" server resources are consuming a relatively idle amount of power, not full power. Probably under 20% of their full load power?
