From a management standpoint, it takes <i>at least 2 developers</i> to run something equivalent.  Perhaps not full time, but it doesn&#x27;t scale out that much - not more than 10 highly available services per team.  A good example of this is roughly a 3 instance RabbitMQ cluster used by ~100 people.<p>1.

Context switching - if you have a developer that also works on coding or other things.<p>So maybe it&#x27;s not a full $240k&#x2F;year for only 1 service, but the price in the door IS that.  2 to 3 extra services will cost no more - that&#x27;s where AWS will make the money.
