AWS Public Datasets
///////////////////////////////
Location: https://aws.amazon.com/public-datasets/

AWS hosts a variety of public datasets that anyone can access for free.
    Previously, large datasets such as the mapping of the Human 
    Genome required hours or days to locate, download, customize, 
    and analyze. Now, anyone can access these datasets via the AWS 
    centralized data repository and analyze them using Amazon EC2 
    instances or Amazon EMR (Hosted Hadoop) clusters. By hosting 
    this important data where it can be quickly and easily processed 
    with elastic computing resources, AWS hopes to enable more innovation, more quickly.
