Im learning about AWS for a subject in the university.
About 20 days ago I started to learn about Elasticsearch because I need querys that DynamoDB can't do.
I'm trying to use only the Free Tier and I created some domains, put data through Lambda (like 100 KiB) and then deleted it.
Then I checked the Billing and I realized that 4.9GB has been used for EBS storage. The Free Tier provide 10GB per month but the problem is that I don't know how I used all that storage and if there is a way to limit it because I dont want to exceed the usage limits.
I will be grateful for any kind of explanation or advice to not exceed the limit.
I'm unaware with preventive step which can restrict your billing.
However, using Cloudwatch billing alarm, you'd be notified immediately as soon as it breaches billing threshold.
Please have look at here for detailed AWS documentation on it.

Recently i discovered my bill raising without using anything above free tier of with very minor charges.
On the bill management page it was clear that the charges are coming from CloudWatch Alarms as you can see in the picture below.
My question is why and how can i stop them? I can see that the alarms are been created by DynamoDB
auto-scaling, but i can't continue being charged for such a simple thing, i'm sure there is an option to disable it but i can't figure out.
Edited I checked "hide auto-scaling alarms" box but i think it's not the fix, fingers crossed to be:P
This is part of DynamoDB AutoScaling. For a small project, you should consider using DynamoDB without Provisionned Throughput.
AWS Free Tier includes 10 Alarm metrics (not applicable to high-resolution alarms).
See How can I determine why I was charged for CloudWatch usage, and then how can I reduce future charges?
I want to use a DynamoDB (specifically with boto3) but I want to avoid getting charged? Most practical way to do this? What sort of usage surpasses free limits?
Please note that the AWS Free Tier is intended as a means of trying AWS services. It is not provided to run production systems.
The Free Tier is a pricing discount provided each month, either for the first 12 months of your AWS Account or, for some services, for every month even after 12 months.
If your usage goes beyond the free usage amount for a service, you will be charged the normal cost of the service.
The free usage tier for DynamoDB provides:
25GB of storage (Value: $6.25)
25 Read Capacity Units (Value: Under $0.01)
25 Write Capacity Units (Value: Under $0.02)
So, the free tier is only saving you $6.28/month at best. If you go a little over this amount, you're probably not going to be spending much.
The AWS free tier page has extensive information on the 60 or so services which provide a free tier, including DynamoDB. You can find the free tier services page here.
As far as avoiding going over DynamoDB free tier limits, there’s a number of potential ways you could handle this. One way might be to use CloudWatch alarms to notify you that you’re approaching the limits, and you could take action when you receive the notification. Another way would be to use CloudWatch events to trigger a Lambda function that sets read and write capacity to 1 when you’re near the limits and thus minimizing your potential overage. In any event, you’ll have to decide what you want to do when you hit those limits, and handle it accordingly.
I am currently signed up to the free tier of AWS. I am enjoying experimenting with various services including those not affording by said free tier. Can AWS's enhanced budgets be used to stop services like EC2 instances if I accidentally spend too much? Or do they merely act as alerts?
This is available for EC2, I don't think it is available for all of the AWS resources.

Hope it helps.
There are several posts which looks it from different perspectives, such as this and this.
Having a cost cap might be a crucial requirement based on the usage, especially when considering how complex it is to set the things up properly and keeping everything secure on the cloud for an average user. At least we can expect to have a feature to switch on/off a cost-cap service, so a user can decide their own scenario easily.
Closest solution that I found is here:
Serverless Automated Cost Controls
https://aws.amazon.com/blogs/compute/serverless-automated-cost-controls-part1
It explains how to trigger AWS Lambda function to change IAM permission from EC2FullAccess to EC2ReadOnly when the budget exceeds the limit.
There is no built-in way to terminate services based on budgets or billing alarms.
You can get notified automatically, but it is then up to you to determine how to handle it.
Would you really want AWS automatically terminating your production infrastructure because you went $1 over your estimated monthly spending?
Edit: There is now a way to monitor and alert on free tier usage, and when your predicted usage will exceed the free tier. See here for details. You could probably come up with a way to terminate infrastructure based on an alert using SNS & lambda.
Edit 2: In Oct. 2020, AWS released Budget Actions - the ability to trigger an action when a budget thresholds are reached. This should give you the ability to automate a response - you can shut down servers, change IAM permissions to prevent additional infrastructure from being created, etc.
Recently, Amazon has given "budget action" to carry out actions like stop services automatically if the budget has exceeded.

About a month ago I opened an AWS account to try out Amazon's own tutorial for EC2 services, only to give up after encountering an error.
Today I accessed my account once again, only to find out three tasks have been running in the background the whole month. My Billing Management Dashboard shows a hefty total in the upper right, but in the "free usage" tier the only exceeded entry is S3 Puts, of about 10%.
I can't seem to find a soruce anywhere in the documentation explaining whether the total billing in the upper right takes into account the Free Tier or not. At the end of this month, will I be billed entirely or only the % difference? I'm more or less okay with the latter, but I can't really afford the former.
I've obviously opened a support ticket right away, but since I'm on the basic plan I'm afraid they might answer me after the current bill becomes active.
Thank you for any answers.
You will be billed only for the % difference.
All services that offer a free tier have limits on what you can use without being charged. Many services have multiple types of limits. For example, Amazon EC2 has limits on both the type of instance you can use, and how many hours you can use in one month. Amazon S3 has a limit on how much memory you can use, and also on how often you can call certain operations each month. For example, the free tier covers the first 20,000 times you retrieve a file from Amazon S3, but you are charged for additional file retrievals. Each service has limits that are unique to that service.

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.
