System Architecture
GSA Advantage is an on-prem system that is currently making plans to move the FAS Cloud.
User Interface: The GSA Advantage user interface was migrated in recent years to Angular web application framework, supported by RESTFul endpoints implemented by Advantage Web Java Enterprise applications.
GSA Advantage is integrated with other GSA systems like PICS, SIP, OMS, and Pegasys to offer buying and e-commerce experience to Federal Govt, DoD and State & Local customers across the globe.
Core Technologies: The Apache Web servers are the entry point to the GSA Advantage application. The core service components of GSA Advantage are implemented using Java Enterprise (JEE) technologies and the core application components are deployed on JBoss. The current data store for Advantage is Sybase. Additionally, the search capabilities are driven by Apache Solr.
