Mendeley uses Amazon Web Services (AWS) to power its research collaboration platform. It stores over 16 terabytes of research papers and citations uploaded by over 1 million researchers on AWS Simple Storage Service (S3). It uses AWS services like Elastic Beanstalk, CloudFront, and Elastic MapReduce to process and render previews of papers, serve search queries across multiple AWS resources, and perform machine learning recommendations at scale. The AWS architecture allows Mendeley to focus on its core product instead of managing infrastructure, while scaling elastically to support over 17 million papers and growing usage from researchers worldwide.
