Does Amazon AWS cost reset every month - amazon-web-services

Does Amazon price for GB storage reset every month? Say in January I used 1000GB of storage and pay it off for $40. Do I get charged $40 in February even if I don’t use any storage or do I pay $0 in February? Basically is AWS storage price static or does it reset every month?

Amazon S3 is charged on two main dimensions:
Storage: A charge for the amount of data kept in Amazon S3, charged per GB per month
Requests: A charge for the number of requests made to S3, charged per 1000 requests
If you keep 1000GB of data in Amazon S3 as Standard storage charged as $0.023 per GB, then you would be charged 1000 x $0.023 = $23 for that month of storage.
If you kept 1000GB of data in Amazon S3 for half a month, then it would be only half that cost.
Think of it like parking your car in a parking garage -- they charge you for every hour that you keep your car parked. However, if your car isn't parked in the garage, then they don't charge you anything.

abnormal AWS billing charges at every first day of the month

So I am using multiple resources in AWS. The charges make sense for most services. however, at every first day of the month, I am getting charged more than I should.
For example; charges for services such as, Aws active directory service, EC2, step function, the elastic search is normal throughout the day. as I can drill down daily charges for these services. but every first day of the month, AWS charging more than what it usually charges. For example; if the average charge for EC2 instances for the day is $5 then at every 1st date(let's say 1st January) of the month, the charges end up for EC2 instance somewhere around $15 and again on 2nd January charges would back normal to $5.
also, for the AWS Contact center telecommunication service, my usual charges for the day would be around $10. but again on the first day of the month, I am getting charged around $150. This is way more than what it charges on regular days.
I don't get this behavior. is it done on purpose or am I missing something?
Thanks.
This is Tax, which appears on the very first day of each month.

AWS billing on demand EC2 price fluctuation

AWS is sending an invoice at the end of each month with the price of the EC2 instance and the number of used hours. Since the price fluctuates, which price is taken to compute the bill? The price at the end of the month, at the beginning of the month or the real price for each used hour?
Thanks
If you are using on-demand EC2 instances, the prices don't fluctuate. When AWS does reduce prices, the new pricing takes effect on a specific date and your bill should reflect the reduced prices as of that date.
There are some complexities in billing when you have credits or Reserved Instances, especially when you use multiple accounts with Organizations or Consolidated billing.
There are some products that have thresholds - for example, S3 standard storage gets cheaper the more you use - the first 50TB are $0.023/GB, the next 450 TB are $0.022/GB, etc.

Are S3 storage costs based on total current usage or on total volume ingested

Suppose I have a script which uploads a 100GB object every day to my S3 bucket. This same script will delete any file older than 1 week from the bucket. How much will I be charged at the end of the month?
Let's use pricing from the us-west-2 region. Suppose this is a 30-day month and I start with no data in the bucket at the beginning of the month.
If charged for maximum bucket volume per month, I would have 700GB at the end of the month and be charged $0.023 * 7 * 100 = $16.10. Also some money for my PUT requests ($0.005 per 1,000 requests so effectively 0).
If charged for total amount of data that had transited through the bucket over the course of that month, I would be charged $0.023 * 30 * 100 = $69. (again +effectively $0 for PUT requests)
I'm not clear on which of these two cases Amazon bills. This becomes very important for me, since I expect to have a high amount of churn in my bucket.
Both of your calculations are incorrect, although the first one comes close to the right answer, for the wrong reason. It is neither peak nor end-of-month that matters.
The charge for storage is calculated hourly. For all practical purposes, this is the same as saying that you are billed for your average storage over the course of a month -- not your maximum, and not the amount you uploaded.
Storing 30 GB for 30 days or storing 900 GB for 1 day would cost the same amount, $0.69.
The volume of storage billed in a month is based on the average storage used throughout the month. This includes all object data and metadata stored in buckets that you created under your AWS account. We measure your storage usage in “TimedStorage-ByteHrs,” which are added up at the end of the month to generate your monthly charges.

This is true for STANDARD storage.
STANDARD_IA and GLACIER are also billed hourly, but there is a notable penalty for early deletion: Each object stored in these classes has a minimum billable lifetime of 30 days in IA or 90 days in Glacier, no matter when you delete it. Both of these alternate storage classes are only appropriate for data you do not intend to delete soon or retrieve often, by design.
REDUCED_REDUNDANCY storage follows the same rules as STANDARD (hourly billing, no early delete penalty) but after the most recent round of price decreases, it is now only less expensive than STANDARD in regions with higher costs. It is an older offering that is no longer competitively priced in regions where STANDARD pricing is lowest.
Your bill will for storage will be closer to your #1 example, perhaps a bit higher because for brief amounts of time, while uploading the 8th day, you still have 7 days of storage accruing charges, but you won't be charged anywhere near your #2 example.
Firstly, you don't need a script to delete files older than 1 week. You can set a transition cycle on the bucket which will automatically do that; or might be transfer contents to Glacier ( with 10% cost ) if you might need them later.
Secondly, storage cost might not be huge.. Probably better idea would be to that script first deletes data from S3 ( if u want script to do that ) and then you add more data.. so that your bucket overall never have more data and you are always charged on consistent storage basis.
Thirdly, your main charges could be bandwidth charges (if not handled well) which can be really huge as you are transferring so much data. If all this data is generated internally from your grid then make sure u create VPC endpoint to your S3 so that you don't pay "bandwidth charges" as then this data transfer will be considered to be transferred on intranet.

will I be charged by aws s3, if I create a post then delete it through admin?

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 ÷ 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.

Amazon EBS pricing: monthly? daily? hourly?

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.
