Did the OP confirm Elon theory that most of the stuff is not needed?
> For four of those years I was the sole SRE for the Cache team. There was a few before me, and the whole team I worked with, where a bunch came and went. But for four years I was the one responsible for automation, reliability and operations in the team. I designed and implemented most of the tools that are keeping it running so I think I’m qualified to talk about it. (There might be only one or two other people)
If you only need one person for the caching department (which is, as I understand, is critical as it delivers most of the data); then maybe you need a handful other dozen engineers and there you have a functional Twitter.
That or the OP is full of himself. Kinda like Musk?
I read this as they built the “tools” (automation, orchestration, monitoring, etc.) for this system, not the system itself; which aligns with the common definition of SRE.
Yes that is the normal case. The post was refuting the assertion that one engineer can run these services indefinitely as previously the OP had the help of SWEs oncall and also fixing bugs.
