The Ops people there were pretty proud of their infrastructure, but they took it to a pretty extreme level. I think they were racking their own stuff and even running their own routers etc.
We actually haven’t had a hardware failure (apart from HDD that have all been replaced with SSD) in something like 7 years.
We don’t even pay big bucks for Dell, HP etc. Just cheap SuperMicro boxes.
There is nothing "extreme" about any of that.
If you own the hardware or use debt it appears on side of the balance sheet where as if you just pay a provider then it is a cost of business like any other software license so it makes the company look finally better even if the overall actual cash cost is 10-20% more.
Also Etsy has had all Senior Management replaced so new technology leader could just be leading the charge as Etsy was a bit of an anomaly running their own infrastructure because that isn't really a competitive advantage for them from the business customer side.
