So maybe AWS isn't the right solution for you. You say in another comment that warnings about billing overages aren't enough. AWS can't hold your hand and provide Netflix-capable services at the same time.
Amazon chose the latter. I would recommend you not choose AWS until you have the time to dedicate to it.
I don't want to "play" with VPS servers, I want to work knowing that I won't go bankrupt just because I'm using at the same time a service that won't let me set up a limit, and a pull payment system (ie. credit cards, as opposed to push systems like Bitcoin).
It's like saying "this website is stupid, it's storing passwords in plaintext", and you answering "hurr, it's the user's responsibility to create and manage cryptographically secure passwords".
And as an analogy, Aws is more like C; if you are willing to put the time in to learn, you can do some amazing things that are impossible with other providers. But you must take responsibility for them.
I'd love to hear use cases where legitimate businesses, who make money off of the products or services they offer, can literally afford to have their business just stop working. It sounds totally contrived.
In fact, we use an SNS->Slack gateway running on a free Heroku dyno to get out alerts in a Slack channel (which is pushed to phones/etc), along with other CloudWatch alarms related to performance.
Honestly, this issue of "I don't have any visibility into what I'm spending" is a waste of energy. You do, and you can have AWS bug you as intensely as you want with updates as frequent and as urgent as you need
It's always best to leave termination of your client's systems up to the client than to pull the plug out from under them... at least I'd like to think that's how they would have reasoned it internally.
Amazon is very easy to work with, if you simply tell them that you are an idiot and fucked up. You're not the only one.
Amazon probably should do a credit check before offering thousands of pounds in credit...
(I am not a lawyer and this should not be taken as legal advice)
(They also almost always help out or completely forgive someone that accidentally ran up a massive bill in a short period of time.)
But, and I don't say this lightly, your behavior in this thread makes me think you just want to complain.
