I am using an ec2 linux instance on aws, I am trying to stay inside the Free Usage Tier, but today I have noticed a charge for DataTransfer cost in Billing Management.
I don't know what the limits for DataTransfer are but I'm using aws for the host of a telegram bot
I would like to stay within the limits of the Free Usage Tier, is there a way to receive notifications just before exceeding the limit for data transfers or simply setting a limit not to be exceeded?
You can set up billing alerts, at any dollar amount you want, but keep in mind that if your service is getting slammed with requests, your account will still keep accumulating charges even after the alert is sent out - so depending on how long it takes you to respond to the alert (and turn off services for example), and how fast services are being consumed, you may still end up with an unexpected bill.

I am using AWS CloudFront and I'm currently free-tier.
I am close to going over 2.000.000 HTTP/S requests that is max allowed for free-tier.
Will AWS automatically charge me for the traffic that goes over those 2.000.000 requests (per on-demand prices) or will CloudFront become unavailable and stop receiving more requests? How do I upgrade to on-demand?
Cloudfront will still be available, however, you will be charged requests for over the max allowed free tiers.
Yes AWS will automatically charge for any excess usage over the free tier quota. Any resource you created in your account will not affect and they will work without any interruption. You do not need to do any upgrades from your side to cater to increased requests.
If you are budget concerned, you can create AWS Budget and create an alert so AWS will notify you before you reach a pre-defined budget. From there you can also define what to do if you reach the budget. For example, you can shut down ec2 instances if this resource consumed more than the allocated budget.
I'm hosting a static website in Amazon S3 with CloudFront. Is there a way to set a limit for how many reads (for example per month) will be allowed for my Amazon S3 bucket in order to make sure I don't go above my allocated budget?
If you are concerned about going over a budget, I would recommend Creating a Billing Alarm to Monitor Your Estimated AWS Charges.
AWS is designed for large-scale organizations that care more about providing a reliable service to customers than staying within a particular budget. For example, if their allocated budget was fully consumed, they would not want to stop providing services to their customers. They might, however, want to tweak their infrastructure to reduce costs in future, such as changing the Price Class for a CloudFront Distribution or using AWS WAF to prevent bots from consuming too much traffic.
Your static website will be rather low-cost. The biggest factor will likely be Data Transfer rather than charges for Requests. Changing the Price Class should assist with this. However, the only true way to stop accumulating Data Transfer charges is to stop serving content.
You could activate CloudTrail data read events for the bucket, create a CloudWatch Event Rule to trigger an AWS Lambda Function that increments the number of reads per object in an Amazon DynamoDB table and restrict access to the objects once a certain number of reads has been reached.
What you're asking for is a very typical question in AWS. Unfortunately with near infinite scale, comes near infinite spend.
While you can put a WAF, that is actually meant for security rather than scale restrictions. From a cost-perspective, I'd be more worried about the bandwidth charges than I would be able S3 requests cost.
Plus once you put things like Cloudfront or Lambda, it gets hard to limit all this down.
The best way to limit, is to put Billing Alerts on your account -- and you can tier them, so you get a $10, $20, $100 alerts, up until the point you're uncomfortable with. And then either manually disable the website -- or setup a lambda function to disable it for you.
We are using AWS Organisations service (with Consolidated Billing feature) with a large member of accounts. Can we set a max limit somehow for the usage cost ($) of the Member accounts?
Would you add a little more detailed description about how can I hook an activity on a billing alert?
I am not sure about your exact requirements, you may check the documentation:
Monitor Your AWS Charges with Billing Alerts.
Managing Your Costs with Budgets
In both cases you can setup alerts on cost/budget, where an alert event is sent to an SNS topic. SNS topic can further send a mail, but the same way you can implement any functionality listening on the topic (e.g. a lambda function)
This way you may monitor total cost/budget usage
usage cost ($) of the Member accounts
You can have a look at Cost Explorer where you can create cost reports per tag or as well per account
(I am not sure if you can create an alert for cost per account)
There is no out-of-the-box enforcement to limit the usage of your AWS account. Alerts can only notify you that you're not in your forecasted budget, but that's it mostly, the rest you should implement on your own.
Couple of thoughts:
Enforcing max limit on your production account is not best practice. You don't want a production interruption or user impact because of a needed scale up in infra.
What you can do is to map your needs and usage, and set quota limits to services. https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html - again, this is not really recommended. Just make sure you have visibility on your growth, set alerts and monitor your usage. Optimization is a key in the could, and the financial responsibility is yours, not AWS.
I just started using AWS services. I want to receive notifications if any service usage exceeds limit. After searching for the options I found that same can be achieved suing AWS Cloudwatch alarm and AWS Limit Monitor using AWS CloudFormation. My question is, will i be charged if i use these services to receive notifications?
Yes, you can setup all kinds of notifications to keep a handle on what you are being billed, but that doesn't stop you from actually getting billed if you exceed your limits.
For example I have alerts to notify me when I reach 25%, 50%, 75% and 100% of my typical monthly spend - so I roughly should get one notification each week - but a lot can happen between when you get sent the notification, and when you take action - especially if, for example, someone got access to your account and started crypto-mining on some big ec2 instances.
I was attracted by the AWS free tier to give EC2/S3 a try. However, one thing I'm worried about is the payment process. There's quite a few management menus and it doesn't seem entirely transparent when I would break the free usage tier (or if I decide to pay, when I break that usage tier).
You can download .csv usage reports, but I wish the billing/usage monitoring was a little more interactive so I don't get unpleasantly surprised. Does anyone have experiences EC2, is there some aspect of the management interface that makes this a easier/less worrisome?
You can monitor your AWS resource usage and the resulting fees here:
AWS Account Activity
https://aws-portal.amazon.com/gp/aws/developer/account/
You can see how current the report is at the top. In my experience it lags by a few hours, which is pretty amazing if you think of how many different customers AWS has and how many little things they have to keep track of to calculate your fees (e.g., every disk I/O request and network byte sent).
Click "Expand All Services" to see the usage/fees broken down even more.
Note: You don't "decide to pay". You already gave AWS your credit card and agreed to pay according to their fee structure. If your resource usage goes over the free tier, AWS will automatically charge your credit card at the end of the month. Monitor the above page regularly to make sure your charges are accumulating as expected.
Use AWS Billing Alerts to notify when you exceeds the fee tier,
If you currently use the AWS Free Tier, you can set a billing alert to notify you if you exceed the free tier by setting a threshold of $0.00.
