How They SRE
From my experience, the $500 Intel NUC in my basement has greater reliability than nearly every single company which calls their IT departments "SREs" now.As an old school IT professional, I would recommend considering most of these companies' advice "how not to engineer reliability".It's possible beyond a certain scale real reliability just isn't possible anymore, but then, anyone below that scale should also avoid SRE practices. Aka, do not use this for your side project.
