I read through the post, and the way it was written, I was expecting it to be an extended analogy for something else. Does "Lubricate Your Keyholes" mean that you need to plan efficient ingress/egress strategies for your cloud services?<p>But no, this was not an extended analogy. This is really just about applying lubricant to physical keyholes.<p>While it is possible that this shaves off a couple of seconds every time you use your key, there are a few things it does not fully take into account.<p>Unless you already have the lubricant at your disposal and understand how to properly use it, you need to take into account the cost and time to acquire it and the time to research how to apply it properly and then actually do the task.<p>That time needs to be subtracted from the time you expect to save via the intervention. And the thing about time is that its value is not static. The author admits as much: "But some seconds are worth more than others, and some seconds have little worth at all." But the author gets the proportion wrong. In the vast majority of cases, you'll likely find that whether it takes you 1 second or 4 seconds to unlock a door, it makes no practical difference to you. Sure, in an emergency, ever second counts, but outside of that (hopefully rare) case, I don't see high ROI.
