My doubt is how the Amazon RDS instance is billed. I read somewhere that it is a component based billing based on the CPU/hour, number of input/output requests, etc.,
How are the I/O requests interpreted? I have a model in which I am trying to reduce the number of input queries that go into the cloud. Will it reduce my yearly cost to a good extent?
Full pricing information is available on the Amazon RDS Pricing page. It involves:
An hourly charge for the RDS instance
A charge for data storage based on amount of storage (including backup storage beyond the provisioned storage size)
A Data Transfer for traffic flowing out of AWS to the Internet
A minor charge for traffic flowing between Availability Zones
There are no charges relating to database requests. In fact, these requests are directly between client apps and the database and are not visible to AWS.
Update: Amazon Aurora also charges an "I/O request" charge. See comments below.

How Aws charges for data out transfer EC2 to internet? and also for first 100gb data out transfer is free for each month for that every month above 100gb data out transfer ec2 to internet. I mean, how they charge?
From EC2 On-Demand Instance Pricing – Amazon Web Services (in March 2022):
Data Transfer OUT From Amazon EC2 To Internet
AWS customers receive 100GB of data transfer out to the internet free each month, aggregated across all
AWS Services and Regions (except China and GovCloud). The 100 GB free tier for data transfer out to the internet is global and does not apply separately or individually to AWS Regions.
Pricing for data beyond 100GB is priced from 9c/GB, but it varies by regions. Please refer to that pricing page for current pricing.
I have aws setup for my website, What I am doing is when a user uploads an image , we are saving it to a folder on ec2 and then transferring it to s3, post which we are fetching images from s3.
I have also stored all the js and css on ec2 and fetching all from ec2 itself.
My data transfer cost is very high now, Please suggest if storing images on ec2 is costing me more ? should I directly store it on s3?
Always think of using CDN or dedicated web hosting services if your web traffics is high. EC2 are only recommended for back-office processing usage than serving web page. There is no free lunch in AWS if you are not careful. You must always check AWS bandwidth pricing before you want to host anything inside AWS. In certain extend, the data transfer costs can be many time more expensive than the EC2 server and (s3, EBS) storage.
AWS only give EC2 1 GB free data transfer to the Internet. After that, it is $0.09/GB. If you open your web server to everyone and 20 bots go download 100GB data daily from your EC2 web server, you will get a hefty bill, i.e. (100GB x $0.09 x 30days = $270 ) - $0.09 (Free 1GB) = $269.01
Also remember, S3 data transfer out to internet is NOT FREE. You only get free unlimited data transfer from S3 to your EC2/lambda within the same region. If you signed the S3 file as a URL to let people download the file, you get billed by "internet OUT" bandwidth charge.
Data Transfer charges only apply to data going from an AWS Region to the Internet. There is no charge for uploading to AWS, nor for moving data between S3 and EC2 in the same region.
If your data transfer costs are high, it suggests that you are serving a lot of traffic to the Internet, either from EC2 or S3.
I want help on understanding the AWS cost explorer graph to track the huge data transfer usage.
I have noticed the AWS account bills for jan, Feb and March (till current date) where it is showing a huge data transfer charge as a bill line item (image attached AWS Bill line Item)
regional data transfer - in/out/between EC2 AZs or using elastic IPs
or ELB
. Further i checked it in AWS Cost Explorer reports by applying Group by filter Region wise and can see that it has data transfer for each region but also for
No Region
, i am not able able to understand this bar graph (please see the image attached and yellow graph AWS Cost Explorer Reports Region Wise) with level "No Region".
A good starting point would be to enable VPC Flow Logs. VPC Flow Logs will show you where the source and destination of all the traffic within your VPC. After you've analysed the logs, you should have a good indication of where to begin investigating.
Out of context but adding it here as it might help you: for some services such as S3, you can enable object-level logging to help you understand what is accessing your objects, which could help you further understand why you're paying for data transfers.
You can avoid paying for data transfer charges between AWS services by using VPC Endpoints. VPC endpoints allow you to connect directly to the service rather than over the internet, which will avoid incurring extra data charges. More on VPC Endpoints here.

How to know the monthly cost of an Elastic Load Balancing instance?
Full detail
My team is using an AWS Elastic Beanstalk instance, and we need to know how much it costs per month.
My google lead me to this AWS page which suggests to view the cost of EC2 and ELB
The principal costs for a web application will typically be for the Amazon EC2 instance(s) and for the Elastic Load Balancing
We can use AWS Calculator to get the monthly cost of an EC2 instance; though we CANNOT find out how to compute the cost for the ELB there ie. using the AWS Calculator.
My google search results as this AWS page which shows a way to compute the cost manually i.e. basing on $0.025 per hour run, and $0.008 per GB of data transfer. But what is the average number of hours and/or transferred data? Why not just have it in the calculator too?
If the load balancer ended up transferring 100 GB of data over a 30 day period, the monthly charge would amount to $18 (or $0.025 per hour x 24 hours per day x 30 days x 1 load balancer) for the load balancer hours and $0.80 (or $0.008 per GB x 100 GB) for the data transferred through the load balancer, for a total monthly charge of $18.80.
To see how much your services are costing you, turn on Detailed Billing Reports. This will create highly detailed billing information, saved in files in Amazon S3.
You can also use the billing option in the management console to see high-level billing by service, but you'll need to turn on Detailed Billing to obtain more detail (and that detail is only available after Detailed Billing is activated).

I've been searching for details of this all day and cannot find any information. I'm using AWS and wanted to know if it is possible, with an amazon service or external, to monitor and log the EC2 compute usage of individual directories?
No, it is not possible to allocate Amazon EC2 usage costs to a fine-grained level, such as individual directory, application or user.
Amazon EC2 is charged on an hourly basis, with the cost varying by:
Instance Type (CPU, RAM, chipset)
Operating System (eg Windows instances include an hourly charge for Windows)
Billing type (On-Demand, Reserved Instance, Spot)
While the AWS billing system can allocate EC2 costs based on tags (eg Department), this is only done for a whole instance on an hourly basis.
Some ideas for fine-grained allocation of costs:
Record usage in CloudWatch via a Custom Metric, then extract data for billing purposes
Store usage information in log files and send them to CloudWatch Logs, then extra data for billing purposes
Track usage in a file, send it to Amazon S3 and then aggregate information each billing cycle
Each of these options would require custom coding and processing.
