Modernizing POS Data Submission in Industrial Manufacturing

Our client, a major company in the industrial manufacturing sector, focuses on developing solutions that improve machine productivity, reduce emissions, lower energy consumption, and enable electrification. As part of their ongoing digital transformation, they required a modern tool for distributors to submit Point of Sale (POS) data.

The initiative was framed as a greenfield project, aimed at replacing an outdated, on-premises system that had become cost-prohibitive and difficult to scale. The legacy system featured slow development cycles and dated deployment procedures, creating bottlenecks in feature delivery and operational efficiency.

The goal was to build a modern microservices-based solution on the cloud, leveraging serverless technologies and establishing a CI/CD pipeline that would allow for frequent, reliable releases.

The project had to be delivered in just 3 months, which included provisioning the entire infrastructure, enabling CI/CD workflows, and deploying fully functional environments (dev, qa, uat and prod).

One of the key client requirements was the use of Pulumi for infrastructure as code (IaC), despite our team's stronger background in Terraform. This presented a learning curve, requiring rapid upskilling to meet the client's preference without compromising delivery timelines.

The engagement began with a series of stakeholder interviews and planning workshops to clarify the end-to-end requirements and define a clear delivery strategy. The team adopted a Scrum-based Agile delivery approach, enabling iterative development and regular feedback loops.

The solution architecture was defined as a microservices-based, serverless, event-driven system, designed with scalability, modularity, and cost-efficiency in mind. It was built to seamlessly integrate into the client's existing, modernized enterprise architecture.

Key Architectural Decisions:

• Event-driven communication via Azure Service Bus
• Use of serverless Azure App Services for hosting .NET microservices
• Pulumi for infrastructure automation and reproducibility
• Support for horizontal scalability and rapid onboarding of new environments
• Critical services deployed behind Private Endpoints to avoid public exposure
• Deployed DNS Zones for name resolution over private endpoints

Despite the ambitious 3-month timeline, the entire infrastructure and CI/CD pipeline were successfully delivered. Our DevOps expertise was critical in aligning practices with both technical needs and business objectives.
