        TECHNICAL DETAILS AT A GLANCE<\/h2>\n \n \n
        \n\n
        \n\n
        \n\n \n

        High Availability<\/h3><\/div>\n <\/div>\n\n

        To ensure seamless availability and performance of the application, a scalable architecture based on Amazon Web Services (AWS) was implemented. This includes the use of load balancers for optimal distribution of incoming data traffic, in-memory caching to accelerate data access, and auto scaling groups that dynamically adjust to load requirements.<\/p>

        • Load balancing<\/b>: Use Amazon Elastic Load Balancing (ELB) to distribute network and application traffic across multiple server instances.<\/li>
        • In-memory cache<\/b>: Use Redis or Memcached to minimise latency and maximise throughput.<\/li>
        • Automated scaling<\/b>: Configure Auto Scaling to automatically adjust resource capacity according to current demand.<\/li>
        • Error monitoring and correction<\/b>: Implement automated tests in the CI\/CD pipeline to detect possible errors early on and use continuous monitoring to monitor system status in real time and take immediate action.<\/li>
        • Redundancy<\/b>: Set up a duplicate infrastructure in different AWS Availability Zones to ensure seamless failover.<\/li><\/ul><\/div>\n <\/div>\n
          \n\n
          \n\n \n

          Clearing & Settlement<\/h3><\/div>\n <\/div>\n\n

          Processing and financial clearing of voucher transactions across different locations requires a sophisticated and automated system that seamlessly supports both the purchase and redemption of vouchers. An automated clearing system has been developed that ensures an efficient flow of funds between the parties involved.<\/p>

          • Transaction management<\/b>: Automatic recording and administration of all voucher transactions between points of sale.<\/li>
          • Balance calculation<\/b>: Monthly calculation of the financial balances between the parties involved to ensure correct billing.<\/li>
          • Document generation<\/b>: Automated creation of detailed transaction histories and billing documents that contribute to transparency and traceability.<\/li>
          • Financial reports<\/b>: Integration of reporting tools for the creation of comprehensive financial reports in real time.<\/li><\/ul><\/div>\n <\/div>\n
            \n\n
            \n\n \n

            REST-API<\/h3><\/div>\n <\/div>\n\n

            The application was developed using an API-first approach, whereby an OpenAPI document was created first to ensure consistency and predictability of the API implementations. The REST API is the backbone of system interactions, including integration with point-of-sale systems and the Print@Home service.<\/p>

            • API-first design<\/b>: structured development based on predefined OpenAPI specifications.<\/li>
            • Integration:<\/b> Connecting various external systems such as point-of-sale systems and online services to enable broad use of the API.<\/li>
            • Security measures:<\/b> Implementing modern security protocols and authentication mechanisms to ensure data security and integrity.<\/li>
            • Maintenance and documentation:<\/b> Providing extensive developer documentation and regular updates to the API to improve usability and customisability.<\/li><\/ul><\/div>\n <\/div>\n
              \n\n
              \n\n \n

              Print@Home<\/h3><\/div>\n <\/div>\n\n

              The Print@Home system allows customers to purchase, print and immediately redeem vouchers from the comfort of their own home. The technology seamlessly integrates payment processing and the printing process, supported by a robust API that guarantees secure and immediate voucher issuance.<\/p>

              • User-friendliness<\/b>: Simple interface for the end user to purchase and print vouchers.<\/p><\/li>

              • Instant validation<\/b>: Automatic verification of incoming payments and immediate issuance of the voucher.<\/p><\/li>

              • QR code functionality<\/b>: Integration of QR codes that enable quick and secure verification of the voucher when it is redeemed.<\/p><\/li>

              • API integration<\/b>: Seamless integration of functions into the central REST API to ensure a consistent user experience.<\/p><\/li><\/ul><\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n\n \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
