Project Summary

ScaleTech Solutions developed a modular microservices architecture for T-Systems International GmbH to integrate with the Infonova Digital Business Platform, enabling billing, data management, API routing and automated workflows using Camunda BPM. The work included CloudBill Sync, Report Sync (with AWS S3 and AWS Athena), an API distribution gateway, import and bulk-processing services, and a search service for dynamic data retrieval. The project delivered significant improvements in billing accuracy and reporting speed, and the team used agile project management with regular updates.

Key Challenges

Develop independent yet interconnected microservices for billing, data management, and API routing.
Automate billing and reporting processes with accurate synchronization and cloud storage.
Enable efficient bulk data processing, account updates, and customer creation.
Build secure API management with validation, routing and multi-tenant support.
Implement dynamic data retrieval allowing flexible inclusion/exclusion of related entities.
Leverage Camunda BPM to automate order processing, notifications, and status updates.
Ensure cloud scalability and high availability for large data volumes.

Project Deliverables

Fully functional microservices integrated with Infonova.
Billing and financial data synchronization system.
Automated reporting and data query execution.
Secure and scalable API Gateway for request handling.
Comprehensive customer operations, including bulk processing.
Camunda BPM-based automated workflow for order processing.
Seamless data flow between microservices and cloud storage solutions.

Project Solution

ScaleTech designed and implemented a set of independent microservices to integrate with Infonova and external cloud storage. They built a CloudBill Sync service for billing synchronization, a Report Sync service that uses AWS S3 and integrates with AWS Athena for dynamic SQL queries, an Import service for bulk uploads, a Distribution API gateway secured with Keycloak for validation and routing, a Search service for dynamic data retrieval, and a Camunda Engine service to automate order-event workflows and notifications. The architecture was modular and designed for multi-tenant support, high availability, and scalable cloud deployment.
