Even if you watch and rein in costs well, when a service actually goes down or a design hits a wall, you need someone's help. AWS knows that the level of help each customer needs differs, and it offers Support Plans at multiple tiers. Today we'll organize the differences across the four tiers from Basic to Enterprise, the dedicated support person TAM, and Trusted Advisor — an automatic-check tool anyone can use.
There's one core question: "How fast a response and how deep a level of help does this organization need?" The answer determines the right plan.
