I am interested in setting up an AWS host that needs to occasionally pull data from another Internet site.
According to the AWS pricing calculator, inbound Internet data transfers are free but outbound data transfers are not. Does this mean I am only charged for the size of the HTTP request but the HTTP response is free? I searched but cannot find an answer to this question. Thanks.
Yes, you are correct. In your scenario, only requests incur charges. Also note that the first 100GB is free. From the docs:
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.

If we have a requirement on 24 hours max for RPO on data stored in Amazon S3, would S3IA be able to satisfy that?
Yes, you can say it could because Amazon S3 data is automatically replicated to 3 AZs in the region, so having a 24 hrs max RPO can ba handled. But what if disaster happens in the entire region?
Would we need a cross region replicate to satisfy this RPO requirement?
Part of your business's recovery objective goals should include identifying what type of outages are worth spending the money to guard against. Do you want to protect your business from a temporary regional AWS outage? Do you want to protect your business from a huge natural disaster that permanently destroys an entire AWS region? Do you want to protect your business from some sort of social or political upheaval that causes AWS to be shutdown in an entire country? Your business has to evaluate the level of outage that they anticipate to be an actual threat, as well as the level of outage that is worth the investment of capital to guard against.
I'm saying all this to explain why asking random strangers on the Internet if you need to implement cross region replication makes no sense. Only your business can answer that question, and simply staging an RPO number does not provide enough information.
Cross region replication, not only to a different region but also to an S3 bucket in a different account, is always a good idea. This gives you protection not only from an AWS regional outage, but also from your AWS account being hacked. Depending on what sort of outages you want to guard against, you may want that bucket to be in a different country, or even in a different hemisphere.

S3 has a storage pricing some $ per GB. Do I get unlimited retrievals or Am I charged when I retrieve or download an object from S3 bucket?
#hephalump only mentioned data transfer costs in the answer. Just so you are aware, you are also charged for object retrieval API calls. The detailed S3 pricing is listed on Amazon S3 pricing page. You can click the "Requests and data retrievals" tab and read the details.
Yes, you pay data transfer charges based on the amount of data transferred. As per the AWS documentation here:
You pay for all bandwidth into and out of Amazon S3, except for the following:
- Data transferred in from the internet.
- Data transferred out to an
Amazon Elastic Compute Cloud (Amazon EC2) instance, when the instance is in the same AWS Region as the S3 bucket.
- Data transferred out to
Amazon CloudFront (CloudFront).
Pricing varies based on the destination and volume but data transfer out to the Internet range from $0.00 on the free tier to $0.09/GB for the first 9.999TB/month.

I am new to AWS and have this basic question. The data stored in S3 bucket, will it incur PUT/GET cost in addition to the storage cost?
Example scenario: (Outside free tier) I am storing objects of size 1GB for 1 day, will I be charged for Storage cost of 1GB in addition to the PUT request cost of those objects.
Thanks for the answers in advance.
As described on Amazon S3 pricing, costs are incurred for:
Storage (per GB per month)
Requests (GET, PUT, etc)
Data Transfer (if the data is going out to the Internet)
All three costs apply.

I am studying first time about Amazon Web Services. I want to know what is the difference or relation between Amazon s3 and Amazon Redshift.
Amazon S3 is storage service.Amazon S3 a simple web services interface to store and retrieve any amount of data from anywhere on the web. With Amazon S3, you pay only for the storage you actually use.
Amazon Redshift is a fast, fully managed, petabyte-scale data warehouse.
Amazon Redshift gives you fast querying capabilities over structured data using familiar SQL-based clients and business intelligence (BI) tools using standard ODBC and JDBC connections. Queries are distributed and parallelized across multiple physical resources.
The relationship between Redshift and S3 is that data can be pumped into your warehouse from s3. More instructions can be found here.

I run a EU-based website on Amazon EC2, and currently send around 13,000 emails a day through Amazon SES. Much of the email throughput is during the early hours of the morning.
Now that Amazon SES has instances in Europe, are there any advantages to me switching from the current US-west SES servers into Europe? Does it make any difference in terms of deliverability or anything else?
The only benefit I can really see is one of slight speed increase; but email sending is done away from anything user-facing anyway.
The only advantage would be in terms pricing, only if you have the servers that are sending email in the same EC2 region as the SES region. In other words if both of them are in the same region, you wouldn't get charged any "OUT" data.
Otherwise you would get charged $0.02 /GB . If you look at the AWS EC2 pricing here: http://aws.amazon.com/ec2/pricing/ , it would be here:
Of course, if your clients are outside Amazon you would get charged "IN" and "OUT" data.
