ive been using/managing/fixing computers and servers for 40+ years. from old AS400 to full on cloud bullshit. i can remember only a single time where boot time mattered… when microsofts DNS failures caused servers to take 15 minutes to boot… other than that there hasnt been a single time it has ever been a problem or discussed as an issue to be resolved.
so why the fuck is it constantly touted as some benefit!? it grinds my gears when i see anyone stating how fast their machine booted.
am i alone in this?
For large scale compute clusters with elastic load I absolutely care. The difference between one and five minutes of boot time when I ask for a hundred new instances to be provisioned is huge in terms of responsiveness to customer requests.
I run massive, global kubernetes clusters in AWS for a company you’ve probably heard of. There is no queue of clean VMs–not like you’re thinking anyway. And provisioning a new node can take Too Long under not-all-that-uncommon scenarios.
The next best option is overprovisioning the cluster, but even 1% overhead has big costs at this scale.
