AmebaPico is a social networking game launched in 2010. It uses AWS services like S3, CloudFront, EC2, and MongoDB. The game had 60 million monthly active users at its peak. It was developed using Flash for the front-end and ran on AWS infrastructure with a MongoDB database. Scaling issues arose as traffic grew, which required optimizing the database and EC2 instance configurations.
