Karsun Solutions enterprise 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 solutions.

The Customer

GSA Federal Acquisition Systems (FAS) was mandated to establish an AWS based integrated platform for applications, data and analytics. The Office of Systems Modernization (OSM) needed to centralize and modernize fee remittance to reduce costs. This web site is used by GSA vendors when reporting their sales made under GSA contracts.

The 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.

Building a Modern Web Application Framework

Karsun Solution proposed Sales Reporting Portal (SRP), a solution utilizing modern web application framework. This implementation combines an AngularJS and NodeJS based presentation layer with a Java Spring based Rest API services layer. This solution was deployed in FAS AWS Cloud Service platform (FCS) utilizing DevSecOps tools. The logical architecture implemented for FAS SRP is as follows:

Karsun also adopted AWS best practices to implement this solution. This includes using managed services such as S3, highly available infrastructure, and deployment automation. The production deployment architecture was as follows:

Some of the capabilities provided by SRP include:

  • Automated process for calculating IFF providing auditability
  • Collecting and comparing transactional data across GSA Contracts will result in market-driven price reductions, increasing FAS market share and saving money for customer agencies which ultimately benefits the taxpayer.
  • Ability to compare transactional data across contract vehicles consistently

The Result

Karsun developed a customized application hosted on AWS platform using Agile and DevSecOps methodology, open source tools, user-centered design approach. As shown in the above diagram, this application was successfully deployed to production on GSA’s FCS platform. Karsun Solutions IT modernization portfolio includes Modern Software Development, Cloud Solutions, and Data Solutions.
