If you don&#x27;t have people on hand who can &quot;open the hood and troubleshoot&quot; I&#x27;d argue you don&#x27;t have people that can run a service on AWS reliably.  The number of gotchas I&#x27;ve run into with AWS is far higher than what I&#x27;ve had to deal with with managed hosting or even bare metal hardware.<p>(I&#x27;m assuming you&#x27;re talking metaphorically, as for my part we use onsite repair warranties to deal with failure of new hardware, and just replace old hardware except when it&#x27;s something very obvious like a failed drive - it&#x27;s rarely worth the trouble to do a lot of diagnostics at smaller scales; in any case you can still save and avoid this by using a managed hosting provider)
