GSA CAMEO FAS Cloud Migration Case Study

Karsun Solutions cloud modernization experts enable the safe transition away from expensive legacy technologies. As an Amazon Web Services (AWS) Advanced Consulting Partner, we leverage the AWS catalog as a key component in these cloud solutions. In this case study series, the Karsun Solutions Cloud Practice shares recent cloud migration success stories.


About the Customer

GSA Federal Acquisition Systems (FAS) was mandated to establish an AWS based integrated platform for applications, data and analytics. FAS Cloud Services platform would fast track cloud modernization for the entire GSA. This platform, FAS Cloud Services, went into full ATO 4 years ago and continues to be refined.

About Karsun Solutions GSA Portfolio

Karsun Solutions provides technical expertise and develops innovative products and services to solve complex challenges facing GSA. This includes a wide range of activities such as quality management and planning, enterprise data management, solution and enterprise architecture, information delivery, application development, testing, and sustainment efforts across the GSA portfolio.

Key Challenge

Based on the new GSA Regulation (Federal Register Notice), published on June 23, 2016, GSA mandated its MAS and Non-MAS vendors must electronically report the price paid for a product item or service purchased through GSA acquisition vehicles on a monthly basis. The existing legacy systems/processes were only capable of handling quarterly reporting and did not provide unified reporting capability to support the new GSAR ruling.


GSA’s FAS Sales Reporting Portal is a new modernization project successfully implemented in AWS in October 2016.  A web-based enterprise-wide application, it processes and stores monthly transactional data and quarterly sales reported by the MAS and Non-MAS GSA contractors while calculating Industrial Funding Fees and Contract Access Fees based on the total sales reported.

Results and Benefits

Karsun implemented a modernized transactional reporting system to support the government-wide category management initiatives by producing market intelligence. Now GSA and its partner agencies may use that information to make smarter acquisition decisions increasing the taxpayer dollars saved by those agencies. This significantly increased the FAS market share and resulted in cost savings for GSA. Other benefits included: Increased accuracy, traceability and transparency in sales and fees collection for both vendors and GSA Eliminated Price Reduction Clause (PRC) tracking and Commercial Sales Practice (CSP) submission requirements for vendors Reduced system footprint leading to lower Operation & Maintenance costs Decommissioned and/or consolidated over ten disparate legacy quarterly sales applications
