If you are serious about reliability you always need infrastructure experts.
AWS is pretty good about documenting the limits of their systems, SLAs, how to configure them, etc. They don't just say you should wave a magic wand -- and even if they did say that, professional software engineers know better.
"a hosting provider that allows allocation of resources via API" is exactly what AWS is. Your infrastructure experts come into the picture because they need to know which resources to request, how to estimate the scale they need, and how to configure them properly. They should also be doing performance testing to see if the claimed performance really holds up.
