Sooo...
What happens when your ONE (or combo of) "service(S)" goes TITSUP? An excavator installing new (gas, water, electric, sewer, etc), and your (AWS, cloud de joure) decides to take a break (s/w, h/w, F'ed update, "operator error", ect.) at 1400 on a Friday? You let the staff go for a (long) weekend? F. the (sales, updates/patches, support, etc.) - Sorry, XYZ, can't help (support, diagnose) ya, ALL our info is on the "Puffy Blue" cloud(s), and we let the staff go to the pub/bar....
Combo, "local" and cloud, is the best taste in my mouth. Age old adage - don't keep all your eggs in ONE basket(case).
Biting the hand that feeds IT
