Bitcoin Full Node on AWS Free Tier

Provisioning

• Launch one T2 micro instance, using Ubuntu 14.04 LTS AMI.
• Open SSH and Bitcoin Protocol TCP ports: 22, 8333.
• Attach 40GB EBS (General-Purpose SSD) volume for blockchain storage to /dev/sdf.

The pricing should be ~3$ for the first year (assuming 30GB upload per month). See here for more details.
