I browsed the Amazon RDS pricing site today and now do want to know how they actually calculate the I/O rate? What does "$0.10 per 1 million requests" really mean?
Can anyone give some simple examples how many I/Os a simple query from EC2 to a MySQL on RDS produces?
In general it is a price for EBS storage service. Amazon claims something like this for EBS (section Projecting Costs):
As an example, a medium sized website database might be 100 GB in size
and expect to average 100 I/Os per second over the course of a month.
This would translate to $10 per month in storage costs (100 GB x
$0.10/month), and approximately $26 per month in request costs (~2.6
million seconds/month x 100 I/O per second * $0.10 per million I/O).
If you have a running application on Linux, here is an article how to measure cost for EBS:

We're gathering logs into Graylog and then store these logs in Elasticsearch. There are 3 i3.xlarge nodes collecting the last 30 days of logs, and 3 r5a.xlarge nodes holding another 700 days of logs older than one month. The warm storage drives are 6144 GiB GP3 EBS with 3000 IOPS and 125 MiB/s throughput.
Just these 6 instances take up about two thirds of our monthly budget.
I'd like to know if storage IOPS limits on both instance types are saturated enough, as I'm looking for possible savings.
CloudWatch gives me numbers like:
Up to 40k DiskReadOps on instance store volumes
Up to 29k DiskWriteOps on instance store volumes
Up to 30k EBSReadOps on warm logs EBSs
Up to 27k EBSWriteOps on warm logs EBSs
Given the EBS limits, I'm not quite sure if the numbers mean that only 3k out of 30k requests per second get processed and the rest is queued. Or is there any burst even with GP3s?
Is my storage saturated IOPS-wise, or is there any space for optimization?
Zoom provides video streaming services, and I made one of my own and considering deploying it on google compute, it says the bandwidth will cost $110 for 1TB if I use it in a month. The cost is pretty much high if we charge a fee like zoom.
If I want to deploy such service it would cost very high considering only bandwidth. What will be an estimate if i had 100 meetings rooms open and in each meeting room 50 participants are there , What would be the estimated cost if they are active for 8 hours per day?
What will be approximate bandwidth they would use considering variable quality of stream, may be 240p, 360p or 720p, considering on the user side they are able to receive the full quality of stream?
Is google calculates egress on the basis of computed data or the amount of data sent to the user regardless of computation of data or a direct download of file?
Person having a good knowledge of google compute please answer.
Thanks in advance.
Google simply calculates the egress or the data sent from the VM considering what goes out of the VM whether it is processed or not.
The price of egress is roughly $0.12/GB, for latest rates visit gcloud pricing calculator.
The egress totally depends upon the number of users downloading or accessing the data on the VM.
So suppose at 240p 40kbps of data is needed on the client side, so
considering 100 rooms with 50 persons each comes to be 5000 clients connected to the VM at an instance.
So, conducting a meeting which lasts 8 hours a day, the egress from the VM would be
5000*(40kbps)*(8*3600 seconds)
= 5*40*8*3600 MB
= 5760000 MB
= 5760 GB
And the cost of such egress would be
5760 GB * $0.12/GB
= $691.2
So, if you have such high bandwidth usage and you want a cheaper option try using digital ocean, their bandwidth is cheaper than gcloud and AWS
There are to many variables to be able to calculate a price, or even egress, however there is a tool available for platform pricing that you can use based on estimates. Cloud Platform Pricing Calculator Hopefully this will be able to give you the information you are seeking
I'm using django and elastic beanstalk. I just made a new post and saw I was charged 0.01$ from aws which kinda worries me. Does this mean every time I make a post this amount will be charged? what if I make one then delete it, will I still be charged? can someone with an experience of elastic beanstalk help me out?
Why not delete it and see what happens to the cost? Deleting doesn't account for data transfer thus my guess is you won't pay a thing. Putting items on the queue does account for data transfer and you will pay. Keeping items on the queue (data storage) will cost you as you can see here: https://aws.amazon.com/elasticbeanstalk/pricing/
Amazon EC2 Pricing (includes pricing for instances, load balancing, elastic block storage, and data transfer)
Amazon S3 Pricing (includes pricing for storage and data transfer)
The actual issue here seems to be a misunderstanding of the terminology used in pricing.
S3 charges $0.005 per 1,000 PUT/POST/LIST requests (some regions are somewhat higher, but this pricing is used through the rest of the answer).
This terminology does not mean that each request will actually be billed as $0.005 รท 1000 = $0.000005, even though this is a close approximation of what they will ultimately cost.
It actually means you are billed CEIL(TOTAL_REQUESTS / 1000) * $0.005...
...where TOTAL_REQUESTS is the number of that type of request you made during a monthly billing interval within one S3 region.
So making 1, 2, 500, 999, or 1000 requests is still a total monthly usage of $0.005, rounded up to $0.01. Not $0.01 each.
Making 1001 through 2000 total requests is a total of $0.005 + $0.005 = $0.01.
Making 2001 through 3000 total requests is a total of $0.015, which rounds up to $0.02.
...ad infinitum...
You wouldn't billed more than $0.01 total until after the first 2000 requests.
I have an instance hosted on Amazon EC2 where the C drive has the following configuration :
Volume type = io1 , IOPS= 2700 .
I was checking the monthly bill and i came across the following cost :
$0.0650000001 per IOPS-month provisioned -US West (Oregon) (blended price)*
4,132.083 IOPS-Mo $268.59 .
Then i started checking the volume via cloud watch (average IOPS counts for each minute) to understand when this IOPS consumption happens on a daily basis
I am confused about the parameters to choose while showing the graph (average ? , sum ? or what it exactly the way to proceed) .
Another graph i made is the consumption during the entire month
But this one is not helping as it is saying i have average consumption less than 200 IOPS on the 26th which is in contradiction with the graph above .
Do you have any better idea to track on the cloud watch my IOPS consumption with parameters that are reflecting the reality to help me make decision .
The dashboard was showing that i am not consuming the allocated IOPS . I then changed the configuration of my Volume to be gp2 instead of io1 . I did not notice any bottleneck since then . You will notice that this alarm supposed to monitor the consumption of IOPS called VolumeConsumedReadWriteOps (Count) is not available for volumes of type gp2.
Here is a great article detailing why you may waste your money on provisioned IOPS .
With Amazon Elastic Block Store, you only pay for what you use. Volume storage is charged by the amount you allocate until you release it, and is priced at a rate of $0.10 per allocated GB per month.
This is priced per month. Other things are priced per hour (and that means that if you use something for two minutes, you still pay an hour).
So what if I allocate 10 GB at 8 AM every day, and deallocate it at 10 PM, so that at no time I am using more than 10 GB. Will I be charged for 10 GB or for 30 times 10 GB?
What if I allocate 100 GB, but only for one day? Will that be the same cost as having the 100 GB for the whole month, or just 1/30th of that?
I have been reading the FAQ and other docs for a while, but could not figure it out.

I've read the FAQ too but let me tell you that if Amazon charged me the $0.10 with a monthly rate I'd be broke by now. I spin up (and spin down) ebs-backed servers several times (30-40) a day and still receive a bill that is not much more than a few dollars.
My guess is that they charge you hourly and this question on serverfault seems to confirm that experience
EBS pricing page at https://aws.amazon.com/ebs/pricing/ makes this clear:
Volume storage for General Purpose SSD (gp2) volumes is charged by the amount you provision in GB per month, prorated to the hour, until you release the storage.
And same for other volume types. So basically the pricing is hourly, just that they put the number in months as it'd be too small to have a reasonable judgement if they put it per hour.
update.
AWS now does per second billing for EC2 and EBS and a few other things too
See this announcement for an overview
https://aws.amazon.com/blogs/aws/new-per-second-billing-for-ec2-instances-and-ebs-volumes/
According to this form page they charge by the day:

See this section:
Sorry, maybe my answer was not clear enough. Let me put it in another
way: No, you will not be charged for the full month. One day only in
that case. That's how "gigabyte months" works.
