AWS: can i use all the 18 free tier eligible products at the same time

Question

Based on the information posted in aws website at http://aws.amazon.com, AWS Free Tier is designed to enable you to get hands-on experience with AWS at no charge for 12 months after you sign up. After creating your AWS account you can use any of the 18 products and services, listed below, for free within certain usage limits. I have created one EC2 instance and I also want to create Oracle RDS at the same time.

The thing that is confusing me is, whether I could use only one of the 18 products or one from each product at the same time?

Answer 1

You can use all of the free tier services at once, but you will have to be within the limits of each of those services to not be billed. Also, the usage per month is fixed and it doesn't roll over to the next month.
