Yeah. By the time you have woken up and read your billing alert email it’s too late.
However the reason it doesn’t exist I suspect is twofold. Firstly because it is bad business. All the cloud providers make a lot of money from mistakes and small things sapping cash. Secondly it’s hard to rationalise what to do when the budget runs out. What do they nuke?
There's a third reason, which I suspect is the biggest. The billing is not real-time, and it's hard to make it even nearly so, especially in such a complex and heavily distributed infrastructure like AWS.
They have realtime insights into how much read/write capacity or IOPS happens on the majority of their services. Their throttling has millisecond resolution. They have no problem giving you realtime insight into when you need to push the magic button to spend more money and increase your write/read capacities. If billing isn't realtime, it's due to sheer laziness or malfeasance (plausible deniability, my guess), because the data is there.
I asked about this a few years ago. The answer I was given by various friends throughout AWS was consistently that of "oh, our customers don't want that" for whatever that's worth.
This is probably technically accurate. After all, I'm sure Amazon, as any business, weights customer voices by the amount of spend. The people spending millions don't want a hard stop (i.e., kill our production services when we hit a certain amount of spend); the only people who want it are the people spending comparatively small amounts, pre-revenue startups, individuals, etc.
This is an example where being data driven to the exclusion of all else can hurt a company; I suspect having this feature would pay dividends down the road (by being the first to provide a safety net for a startup with a fixed budget that doesn't have production workloads yet you offer a competitive advantage between cloud providers), but the effect is completely impossible to predict or track currently since it doesn't have an immediate impact on revenue or the satisfaction of large, paying customers.
Pro-tip: "the data is there" doesn't mean it's cheap to use.
There's a very simple explanation for this; realtime billing would increase the cost of the product they sell to create something most people don't need.
>Besides, if they can trigger alerts at a particular spend then they should be able to create a limit.
That's not really true. The alerts happen when the billing is re-calculated (periodically) and you've exceed a predefined, not when you hit that exact threshold.
>When you enable the monitoring of estimated charges for your AWS account, the estimated charges are calculated and sent several times daily to CloudWatch as metric data.
Real time billing is actually a Hard Problem to solve.
> Real time billing is actually a Hard Problem to solve.
I refuse to believe there is no workaround. I can understand it is not easy to fix for corporations who need AWS to make money but that is not the use case for students.
If it were, Azure for students couldn't exist. Signing up for Azure for students does not require a credit card so they must have figured out a way to prevent / stop the bleeding?
Well stop the service on that periodic cycle then if it’s over the limit?
Non-realtime limits are better than no limits at all. Besides the cloudwatch documentation seems to suggest it’s reporting on a 5 minute frequency for most of AWS.
Billing is very tricky from the metering to the final PDF bill which includes taxes, promotions and whatnot. So this is hard if you want to put limits on a certain dollar amount. You could also put hard stops on resource usage (say, no more than 500 CPU/hr/month)
Besides, AWS already complicates things way too much by handling VAT like other billable items instead of just adding it at the final step like any sane company would
I think the solution would be to allow customers to set hard limits, so they at least have an upper bound on their monthly spend, while still being charged on their actual usage (in a nonrealtime fashion).
This also solves the problem of "what to cut". If I hit my bandwidth limit AWS simply stops routing requests to my servers, if I hit my CPU limit AWS should throttle me, etc.
This feels (no disrespect to you) like a huge cop out. How many more small, "let's hack this together and hope for the best" projects are they missing out on because developers feel uncomfortable with the black box that is AWS billing? I suspect it would be a significant number, believe it or not.
Both AWS and shared hosting providers run on a “F you. Pay me!” model. The difference is that small hosting resellers knew they couldn’t collect on debts while Amazon knows it can.
Even if not realtime, it sounds like a better option than AWS' current "not supported at all; you'll have to manually shut things down if costs overrun".
AWS sorta has something like this already with CloudWatch, but it'd be nice if it was simpler and immediate instead of reactive. I just run a little reserved EC2 instance so my main billing risks are excessive data out or forgetting to renew a reservation and reverting to by-the-hour billing. So that I don't worry about it much I have three alarms that notify me if either "estimated charges > $x for 1 datapoints within 6 hours", or there's "anomalous" NetworkOut over a day, or "there's more than X total NetworkOut over a day", and another alarm that's "NetworkOut > Y for 1 datapoint within 15 minutes" that notifies me and shuts the instance down. I'd like to have a hard cap of "my instantaneous billing running total for the month, not my 'estimate', has exceeded $x, shut everything down" but what's there is something.
I use AWS for a very small side project. I used about $10 back in July, and I don't expect any more costs for several months (aside from S3 hosting).
It would be really nice if I could preload $100 into the account and remove my credit card. I don't have ANYTHING sensitive behind my username and password- except my CC #
I know they are never going to implement this because I'm small potatoes, but it would be nice
For data out I have some alerts set similar to yours to shut down the instance if NetworkOut becomes unusually high—over three different time scales. Since the alerts are delayed, though, I also set up traffic shaping rules in the VM to throttle the NetworkOut to something reasonable so that it doesn't incur a huge bill before the first alert triggers. Officially the VMs have 5 Gbps network links; at that rate you can accumulate quite a large bill in a very short time if the VM starts saturating the link.
I came here to basically say something like this: if there's a hard limit, your business will basically shut down entirely. It's hard (impossible) for cloud providers to automagically shut down services based on each customer's priorities.
I don't think there's a magical solution to this. There might be a company that sets a $1K USD/month limit, forgets about it, and suddenly the cloud provider shuts down everything a year later, while "everyone" is unavailable or something like that.
There are so many scenarios, and I honestly feel that the cloud providers have decided on the most fool-proof solution both for them and their clients.
Ok. But the Auto Scaling Groups are free - so I can keep that on, right? Oh, look! They just launched more EV2s, how convenient. Should I back these up to S3? With CRR enabled?
That scenario implies that someone has made a mistake. They forgot to turn off a service or turned on a service by accident. How does AWS know that the billing cutoff wasn't the accident? Maybe I accidently set a $20 cutoff during building my MVP instead of $200, but now that I have a paying customer I'm going to hit $100/month. AWS could disable my very first customer because I forgot to fix my billing setting.
Doing nothing is generally better from a legal liability point of view. The customer should be liable for turning services on and off.
[Disclosure] I'm Co-Founder and CEO of a company named http://vantage.sh/ that helps developers track and reduce cloud costs - I also previously worked at both AWS and DigitalOcean.
We hear about this all the time from AWS customers and its a large reason why people connect their account to Vantage which will help alert you if costs change intra-month. The first $2,500 in AWS costs per month are tracked for free so I thought I'd mention this here for potentially being helpful to the community.
If you don't want to remember to set up billing alerts, we provide basically a turn-key experience around this that takes less than a few minutes to setup: http://vantage.sh/
The list of permissions is a whittled down version of what's available in the AWS managed policy of "ReadOnlyAccess" and doesn't allow us to do things like read from S3 Buckets or read from RDS instances. Basically just List/Describe actions.
IAM permissions are written about more here in our documentation and are ultimately handled gracefully if you want to remove some. For example, if you just want to hand Vantage access to billing, S3 and EC2, it will do the job as best it can with just those permissions: https://docs.vantage.sh/permissions/
Use a disposable credit card (like lastcard or privacy) and set the limit to $5. Add it to your account, and the max they can charge is $5. If they let you run past it, the billing will fail, and if they don't shut it off it's on their dime.
To everyone claiming "ohhh that's illegal/unethical" I say to you: take it in your favor for once. For every 100 clients aws bills unexpectedly and with no controls in place to mitigate, you can be the 1 who gets a free month of service. They will not pursue you for $5. Imagine making the argument for welfare on a company that is worth a trillion dollars.
> To everyone claiming "ohhh that's illegal/unethical" I say to you: take it in your favor for once.
The rationale against doing this is as much practical as it is moral --- unless you're just doing this once for a single month and don't care if your account gets banned. AWS isn't like an auto-renewing subscription, where if the card declines, your service is cut off. They won't charge the card with a $5 limit until the end of the billing period. If you rack up more than $5 in charges in a billing period, you will be in debt to Amazon. They will certainly ban your account, so you'd have to make a new throwaway account with a new disposable CC each month.
You'd be humbled (perhaps not) by how little human capital gets assigned to review and correct anything under 5-figures at AWS. The account gets put into overdue and the services stay paused, you get an email every so often (if you even put in a valid email). Pretending they have a crack team of hundreds of analysts sitting there waiting to ban every account associated to an IP for $5 is pretty farcical. I have several 6-figure AWS accounts at present, and I can barely get ahold of a human being when there are issues related to wire payments not being applied to an account, let alone imagine they'd have anyone worrying about this beyond putting a dev on it to set up an ignore filter on such accounts. They have a manual process to allow any accounts to spend above $2000 or $5000 (I can't remember) where you fill out a credit application and they vet you to see if you are indeed good for it before allowing you to provision further. If you default on that, they will carefully weight the cost of collecting you or even reporting it to a credit bureau vs the amount due.
Not advocating for mass fraud here, or even petty fraud, just making it a bit more fair to those who have 0 provisions in the platform to prevent involuntary overspending.

You are not doing delivering some sort of poetic justice, you are just showing your lack of self-preservation instinct. For your own welfare, just don't poke the bear. You don't wanna get blacklisted for doing some dumb crap that will come bite you in the ass someday.
There are enough stories running around of people getting their job accounts banned by association for pulling idiotic stunts like these, and we don't know what crap Amazon will be running in the future.
The only problem is that they'll let you go negative for awhile before they shut you off. Then they won't let you use any services until you pay your balance. So unless you're willing to make a new account each time you go over your $5 max, you'll still be paying for the extra usage
Do you think it's an important feature for their paying customers? I've worked at places that care a lot about their AWS bill but I don't think any of them would have wanted a genuine hard stop before they'd do anything about it as a result of the soft alerts.
I've used AWS for my personal projects and at work. When I started at work, I didn't fully realize that "when an EC2 is spun up, you are charged for 1 hour, even if you terminate it" - so I accidentally racked up a big bill.
I was thinking it would be useful if Organizations could pre authorize users at $X before preventing them from doing more - of course the better solution is to manage releases through a pipeline that checks for stuff created and code scanning and... whatever
In the end, we use cost monitoring, but no AWS billing alerts
Do you think it's an important feature for their paying customers?
I think it is.
A few jobs ago, the boss of my boss got fired for a cloud service overage. Not a huge amount; the number on the grapevine was around $10,000. But it was enough.
For many (numerically "most," probably) companies, the IT department is a black box to upper management, and any unexpected budget overages are a serious problem.
The users who actually pay AWS decent money or are likely to pay AWS decent money in the future don't ask for this afaik. People paying $5/month for AWS aren't AWS's target audience and likely contribute negligible revenue to AWS.
People do ask for alerting and monitoring but that's not a hard stop.
Then you get complex issues such as S3 and EBS. As long as there is data you will keep paying so what do you do? Have a hard limit but not really since it doesn't cover them? Delete people's data?
You don't get to be the biggest by not charging people. They probably make more off accidental billing than the people who contest those accidents, so it's worthwhile. That's why Columbia House was so hard to cancel back in the day - it wasn't the $0.01 CD where they made the money, but on the monthly fees that were way more than the cost of one CD.
I don't think it has anything to do with wanting to collect money from accidents. That's not very reliable revenue anyways. That's just an unfortunate side effect for us plebs.
The real reason is that if you give companies a budget feature, they will inevitably, you know, use it. They'll set a budget that seems 'reasonable', and then freak out when everything turns off when it's exceeded, and then go raise it a little bit, and repeat the cycle.
Compare that to now where every place I've ever worked basically seems to forget that cloud hosting costs even exist, based on how much most companies balk at paying for simple SaaS tools for developers but will happily let the hosting costs grow to astronomical amounts. They're happy to do it cause they just see a line item and accept it. If you give them budgets, that won't happen any more.
>I don't think it has anything to do with wanting to collect money from accidents. That's not very reliable revenue anyways.
It's worked well enough for the entire fitness industry forever. No reason it can't work here as well, and at scale I'm sure it's pretty profitable. You're right, too, that we'd use it, but I think this is a situation where we can both be right.
At the scale of Joe's Chicken Shack, accidental revenue is not reliable. But at the scale of a Google or an Amazon, while it will fluctuate month to month, a certain minimum revenue stream should be statistically predictable.
I'm sure it's a terrible idea for some reason, but I love the idea of setting up a service with a wallet that pays for itself. Anyone can add funds to the wallet. As long as the wallet has funds, the service keeps running. I especially love the idea of the provider (AWS, GCE, Azue, whatever) setting up the wallet, and guaranteeing there's no way to withdraw from the wallet, so you know the funds you deposit really do go to funding that service. Then, give the service a way to see which account has deposited funds, so they can credit you for funds you deposited... I mean, I would just love to see more services running "self-funding" like this.
Not that easy to do. I don't think any major users are requesting this, and what to do when you go over the limit? Start deleting resources automatically? What about the data? Backups?
Azure has quotas that can limit things such as the number of VM's you can have running per region. It won't provision more vm's than you have in your quota. This helps you, for example, avoid automatically provisioning more vm's than you expect. These quotas can be edited manually or via API.
Have you visited their S3 console recently? It's gotten pretty striking visual markers now for Public visibility. I don't have a screenshot handy, but thought I'd mention it
If you mistakenly spend a small (to AWS) amount of money, they'll refund it. They're not out to get individuals.
AWS is for businesses and hard limits on spending is a liability for their pricing structure. Imagine you run a small business built on AWS and you hit your limit -- you're basically asking AWS to dismantle your business. They'd have to null-route traffic directed to you, shut down your servers, delete your data, de-allocate your IP addresses, etc. Your business won't be any better off than if you went bankrupt from a huge AWS bill.
Or Google. When I was a student I forgot about a TPU instance and spent over $10K in a single month, on track for $100K. Google refunded me since the server was at idle for most of that month outside the one hour I used it for.
However the reason it doesn’t exist I suspect is twofold. Firstly because it is bad business. All the cloud providers make a lot of money from mistakes and small things sapping cash. Secondly it’s hard to rationalise what to do when the budget runs out. What do they nuke?
