I have a small doubt regarding the AWS free micro tier instances. If i run a EC2 micro instance and RDS micro instance for one month (720 hours each) will i get billed since the 750 hours free quota will be crossed when both are combined ?? Or free tier usage is calculated separately for each instances
The free tiers are independent by service, so as long as your EC2 instances don't go over 750 hours per month (and the instance types are eligible), and your RDS instances don't go over 750 hours per month (and the instance types are eligible), you'll be within the free tier.
So in your case, using 720 hours for EC2 and 720 hours for RDS with small enough instances would be free (for the first 12 months of AWS membership).

I use AWS free tier to spin up t2.micro boxes and use it to practice Docker since the download speed is vastly great when pulling large images in mere seconds.
I am assuming download is free and upload -pushing images for example- is chargeable although not sure the exact amount.
How much are the costs here?
You incur upload costs when you exceed more than 1 GB upload per month. Please see: https://aws.amazon.com/ec2/pricing/on-demand/#Data_Transfer
Note that I'm providing a link here rather than providing values because the costs may differ from Region to Region, and from year to year.
For more information on the Free tier limits have a play with: https://aws.amazon.com/free/
Also, remember that it is 750 hours of t2.micro or t3.micro a month. You could spend all these 750 hours with 1 instance and that would take 750 hours. If however you decided to run 750 instances then you would use up your whole months 750 hours in 1 hour.
Lastly remember your EBS limit is 30 GiB. If you launched 4 Ubuntu instances with 4 root volumes of 8 GiB then you would be exceeding your free tier limit by 2 GiB.
Data Transfer IN To Amazon EC2 From Internet: No charge
Data Transfer OUT From Amazon EC2 To Internet is charged at 9c/GB (in US regions).
Also: "As part of AWS’s Free Usage tier, new AWS customers will receive free 15 GB of data transfer out each month aggregated across all AWS services for one year except in the AWS GovCloud region."
I'm new to AWS and trying to learn its concepts. This one is really confusing to me about the AWS Free Tier.
This says 750 hours of free COMPUTE each month, (24 hours * 31 days = 744 hours).
My question is when will I end up overusing it? As I don't want to pay any money in first year.
The full description is:
750 hours per month of Linux, RHEL, or SLES t2.micro instance usage
This can be used as one instance running all the time, or two instances running for 375 hours or 10 instances running for 75 hours, etc. It is applied as a billing discount, giving the first 750 hours at no charge.
If you run ONE t2.micro instance, then there will be no charge for the instance during the first year.
However, there might be some associated charges such as Amazon EBS Volumes, Elastic IP addresses (if not attached to a running instance), data transfer, snapshots and T2 Unlimited. There is a free tier for each of these, but charges will apply if the free tier is exceeded.
I'm set a website using the Amazon free tier in an EC2 instance. The free tier is giving me 750 hours of EC2 Linux t2.micro instance usage. I would like to know how the instance hours are counted to ensure the usage doesn't exceed the free tier limit.
I suppose if my website is not down the instance should be running 24 hours a day which will result in a maximum of 24 hours x 31 days = 744 hours per month usage.
Is that the case?
The AWS Free Tier provides 750 hours per month for a t2.micro Linux instance.
Therefore, if you keep one t2.micro Linux instance running for an entire month, then there is no charge for Amazon EC2.
You could, alternatively, run two instances for half a month each, since that would combine to the same total hours.
EC2 instance usage is calculated by the second or by the hour, depending on which AMI you're using:
per-second for most Linux distributions
per-hour for Windows, and for Linux distributions that have a separate hourly charge
If your instance is per-second, then you're billed a minimum of 60 seconds each time an instance starts.
If your instance is per-hour, then you're billed a minimum of one hour each time an instance starts.
An instance is considered to be 'started' when it enters the running state.
I have an Amazon AWS account, with a few EC2 running instances (3) in different locations. I subscribed the 12 month trial. Suddenly, my billing dashboard started to stack up costs, updating every day.
The instances are virtual machines with windows server 2012, all configured under the free tier settings. I use them mainly form testing, with few downloads/uploads and streaming.
They Are charging for a few bucks for data transfer,and also a reasonable amount described as EC2.
I've read somewhere that one could create more than one EC2, and for what i supposed, the 750 hours limit is for each instance, But this probably is Wrong.
So, what can one do and not do, under the free Absolutely free tier limit ?
Based on the documentation you can run 750 hours of a Linux t2.micro or t1.micro instance plus 750 hours of a Windows t2.micro or t1.micro instance each month for the first 12 months under the free tier. So in your case you have exceeded the free tier limitations, by starting 3 Windows Server 2012 instances and keep them running more than 2/3 of the month.
Since AWS Free Tier involves 750hrs of Free Time per month, you could ideally start 750 EC2 instances, 1 hour/per month.
Is there any changes for "traffic" when using basic version of EC2 instance, by basic I mean:
750 hours per month of Linux, RHEL, or SLES t2.micro instance usage
Traffic: If we setup a server and there are some hits on my server then is there any charge for this setup. I am not using ELB, just EC2 instance with a server on it.
The full pricing for On-Demand Amazon EC2 instances can be found at: https://aws.amazon.com/ec2/pricing/on-demand/
The AWS Free Usage Tier gives 750 hours per month of a t2.micro instance. This means you could run one instance for a full month, or two instances for half a month. Simply stop the instance(s) to stop the charges.
You can have this free usage tier for a Linux AND a Windows instance.
However, please note that there are additional charges that also apply:
Data Transfer: This is charged for data leaving the AWS Region going to the Internet. The free usage tier includes "15 GB of bandwidth out aggregated across all AWS services" in the first 12 months. The EC2 pricing page also says that the first 1 GB/month is free, but I'm not sure if they overlap.
EBS Volume storage: Elastic Block Store (EBS) runs the disks attached to your instance. The free usage tier includes "30 GB of Amazon Elastic Block Storage in any combination of General Purpose (SSD) or Magnetic, plus 2 million I/Os (with EBS Magnetic) and 1 GB of snapshot storage", so you will be charged if your disk storage exceeds this (which is likely if you run both a Windows and a Linux instance). This storage charge continues to apply when an instance is Stopped, but not when an instance is Terminated.
Bottom line: Stop or turn off things when you don't need them. You can also activate a billing alert to warn you when you have been charged some actual money.
Yes, there are varying charges for traffic into and out of your EC2 instance.
in very rough numbers, if you budgeted $0.01 per GB of traffic, you would come in under that, but the complete breakdown is here:
