Pricing for using SQS within EC2 - amazon-web-services

If messages are both sent and received from different EC2 instances in the same region, there will be no cost right?
In other words, messages are only billed if it's coming from or going to non-EC2 instances/systems?

See the Amazon SQS Pricing page for details of SQS pricing.
It is charged as:
Price per 1 Million Requests after Free Tier (Monthly)
Plus data transfer
A request includes SendMessage, ReceiveMessage, DeleteMessage, etc.
The Data Transfer charge within a Region is free. For example, if requests come from an Amazon EC2 instance in the same region as the Amazon SQS queue, there is no charge. The Data Transfer charge only applies for data going out of the cloud, eg to the Internet or to another Region.
As per the page:
Data transferred between Amazon SQS and Amazon EC2 within a single region is free of charge (that is, $0.00 per GB). Data transferred between Amazon SQS and Amazon EC2 in different regions is charged at Internet Data Transfer rates on both sides of the transfer.

AWS pricing for S3 object download using site-to-site VPN

I would like to understand the monthly cost of using a VPN site-to-site link to transport data from S3 to my on-premises host. I will use AWS Lambda to transfer around 12 TB of data each month from S3.
Using AWS calculator, I checked the S3 and VPC tabs and noticed that there is a "Data Transfer OUT" in both services.
For this use-case will I have to pay the "Data tranfer out" fees for each service?
Thanks

You can create a VPC S3 Endpoint to make the S3 service accessible for your Lambda function without counting outbound data.
I will use AWS Lambda to transfer around 12 TB of data each month from S3
You will still pay internet outbound from VPC.
If you plan to transfer the data to your on-premise destination, you may consider establish the (already mentioned) AWS Direct Connect service
Data Transfer Out is charged when data goes from AWS to the Internet. It is only charged once, at the exit point.
If data is going across an AWS Direct Connect link, then the Data Transfer price is lower.

Cloudwatch log store costing vs S3 costing

I have an ec2 instance which is running apache application.
I have to store my apache log somewhere. For this, I have used two approaches:
Cloudwatch Agent to push logs to cloudwatch
CronJob to push log file to s3
I have used both of the methods. Both methods suit fine for me. But, here I am little worried about the costing.
Which of these will have minimum cost?
S3 Pricing is basically is based upon three factors:
The amount of storage.
The amount of data transferred every month.
The number of requests made monthly.
The cost for data transfer between S3 and AWS resources within the same region is zero.
According to Cloudwatch pricing for logs :
All log types. There is no Data Transfer IN charge for any of CloudWatch.Data Transfer OUT from CloudWatch Logs is priced.
Pricing details for Cloudwatch logs:
Collect (Data Ingestion) :$0.50/GB
Store (Archival) :$0.03/GB
Analyze (Logs Insights queries) :$0.005/GB of data scanned
Refer CloudWatch pricing for more details.
Similarly, according to AWS, S3 pricing differs region wise.
e.g For N.Virginia :
S3 Standard Storage
First 50 TB / Month :$0.023 per GB
Next 450 TB / Month :$0.022 per GB
Over 500 TB / Month :$0.021 per GB
Refer S3 pricing for more details.
Hence, we can conclude that sending logs to S3 will be more cost effective than sending them to CloudWatch.
They both have similar storage costs, but CloudWatch Logs has an additional ingest charge.
Therefore, it would be lower cost to send straight to Amazon S3.

Does AWS S3 charge requests for EC2 transfer?

I understood from the pricing sheet that data transfer is free between EC2 and S3 in the same region, but will I still be charged for GET, PUT etc. requests?
You are correct -- there is no Data Transfer charge for traffic between Amazon EC2 instances and Amazon S3 within the same region. (The same goes for other services, too.)
However, these charges still apply:
Storage pricing
Request pricing

aws sns, sqs and ec2 within single region for push messaging

I am willing to make a simple chat application in django.
After user sends message and the message in saved in Message model I would like to signal the publish event so that my mobile app gets message.
I went throught the SNS documentation and in its pricing I found Data transferred between Amazon SNS and Amazon EC2 within a single region is free of charge (i.e., $0.00 per GB)
My api is/will be hosted in ec2 in the same region lets say at Singapore the same region as sns. If I publish a event which I receive a message in my mobile application , will that cost me or it is considered as same region ? If it does than building a chat application using SNS will be very expensive.
If anyone can meke me clear about it that would be so helpful.
Thank you
Well I don't think it will be free even if they are in the same region but their prices for SNS are too low, if in free tier of Amazon you won't be charged for
1,000,000 Requests of Amazon Simple Queue Service every month**
1,000,000 Requests, 100,000 HTTP notifications and 1,000 email
notifications for Amazon Simple Notification Service every month**
as the SNS pricing suggests. Going above the limits will cost you :
It costs $1.00 to send one million mobile push notifications ($0.50 per million publishes, plus $0.50 per million mobile push notification deliveries). When you use SNS topics to broadcast identical messages to many recipients at once.

Amazon S3 Bucket data transfer charges applicable while mounted in EC2 server?

I have created an S3 Bucket and mounted into one of my EC2 servers in the same region. Then I put data into the bucket using FTP account created for that EC2 instance. Finally, I access the data by Http request.
I'm not accessing S3 bucket directly from Internet, either for writing or accessing. All the data transferred through EC2 instance.
So, I assume per month charges as below, for fully used up 1TB S3 bucket (standard storage),
Storage Pricing - $0.0300*1024 = $30.72
Request Pricing - $0.005*10 = $0.05 (Assumed 10,000 request per month )
Data Transfer Pricing - Nill (Since the bucket is not being accessed directly)
Is that correct? or data transfer pricing is applicable?
Ref: Pricing Details
You do not pay for data transfer between S3 and EC2 in the same region, however you pay for Data Transfer OUT From Amazon EC2 To Internet or EC2 instance in a different availability zone in the same region.
See EC2 pricing for more details.
If you transfer 1TB of data OUT to Internet from AWS, either directly from S3 or through EC2 instance, you will pay the same price.
TIP:
If you are transferring big amount of data from S3 out to Internet, look into CloudFront. Data transfer EC2/S3/ELB -> CloudFront is free of charge and CloudFront has cheaper rates per Gb compared to downloading files directly from S3.
EDIT:
see #Michael - sqlbot's comment, this is often but not always true depending on S3 Bucket's region and CloudFront edge location serving the content.
TIP 2:
For really large amounts of data it might be worth setting up DirectConnect connection (private connection from your office / on-premise setup to AWS). Then Data Transfer becomes even cheaper per Gb, however you start paying hourly rate for your DirectConnect link. Do the math to calculate what's best for you.
If you are reading data from S3 to your EC2 instance, and the S3 bucket is in the same region as your EC2 instance, then there are no data transfer costs.
Broken down:
There is no “data transfer in” costs to your EC2 instance if the data is coming from an S3 bucket in the same region: EC2 Instance Pricing – Amazon Web Services (AWS)
There is no “data transfer out” costs from your S3 bucket if the data is going to an EC2 instance in the same region: Cloud Storage Pricing – Amazon Simple Storage Service (S3) – AWS
There is no "data tansfer out" costs from EC2 to S3.
