It&#x27;s been true five times in the last three years for me.  The elasticity isn&#x27;t always there and service limits are not always granted when needed.<p>I don&#x27;t know what an AWS TAM is but the SAs have tried and failed.<p>Make a new account and try to run 1000 c4.4xl in parallel for 1 hour.  It won&#x27;t happen.<p>That&#x27;s not what happened the five times, but it&#x27;s illustrative.<p>And who defines what is a need and what is a want?
