Data transfer costs in AWS

How do I estimate for data transfer costs for applications running in AWS

  1. Will there be a data transfer cost for traffic from AWS loadbalancer to the application running in a EC2 environment
  2. Will there be a data transfer cost for files uploaded into S3 through an application running AWS EC2
  3. Will there be a data transfer cost for files retrieved using AWS Cloudfront in a web application, by end users from within the country (say Russia)
  4. Will there be a data transfer cost if the application running in AWS EC2 makes a call to an Elasticsearch instance running in https://cloud.elastic.co
Solution

  • Data Transfer is only charged for traffic exiting AWS and going to the Internet, although there is also a small charge for traffic between AZs and Regions.
