Not worth trying if you are going to use the free AWS EC2 read the terms below.
You may not use AWS Services under any Offers to mine for cryptocurrency. If you use AWS Services under an Offer to mine for cryptocurrency, we may charge you standard rates for your use of the AWS Services, and we may suspend your right to access or use any portion or all of the Service Offerings.
If you are paying then it still not worth mining on AWS. Much better invest in buying ASIC or GPU compared to paying AWS EC2 service.
