Cloudgene system architecture. Cloudgene consists of two independent modules, Cloudgene-Cluster and Cloudgene-MapRed. Both implement a client–server architecture using open source technologies. The client is implemented in JavaScript utilizing Sencha Ext JS and communicates with the Restlet server via a secured connection (HTTPS). The program parameters are read out from its manifest file written in YAML. Both modules are username/password secured and store all required metadata in the relational SQL database H2.
