Modernising Healthcare Solutions on AWS

Interway is a Macedonian software company developing tailored digital solutions for clients in the financial and healthcare sectors. With new product opportunities emerging and compliance standards tightening, the company recognised the need to modernise its platform to ensure future readiness, improve reliability, and reduce operational overhead. They partnered with PCG to deliver a secure, cloud-native transformation aligned with AWS best practices.

As with many software vendors serving regulated industries, Interway was facing increasing strain from an ageing application architecture. Their healthcare platform, in particular, needed to scale more easily, meet data security expectations, and support faster delivery cycles.

While these goals were familiar across the market, Interway’s challenge was made more acute by a monolithic architecture that slowed deployments and created barriers to innovation. Manual operations, patchy observability, and inflexible authentication all contributed to mounting technical debt.

Ultimately, the company needed a modern, scalable environment that would support secure healthcare data handling, reduce deployment friction, and enable product teams to deliver faster.

• Monolithic architecture limited scalability
• Manual deployments increased risk and effort
• Authentication lacked healthcare-grade security
• Limited automation across the delivery pipeline

Interway’s leadership saw this as not just a technical upgrade—but a strategic shift to support sustained product growth and market trust.

To meet Interway’s requirements, PCG designed and delivered a fully containerised, cloud-native solution using AWS services. This modernisation initiative included decomposing the legacy monolith, automating CI/CD, integrating identity management, and optimising data access—all within a compliant, high-availability framework.

• Microservices Architecture
  The existing monolithic backend was split into containerised microservices deployed on Amazon ECS with Fargate for scalable, serverless orchestration without infrastructure management.
• Automated CI/CD Pipelines
  Deployment pipelines were built using AWS CodePipeline and CodeBuild, connected to GitHub triggers for both backend and frontend codebases—ensuring rapid, repeatable releases.
• Secure Identity and Access
  Amazon Cognito was implemented to meet healthcare-specific authentication standards, with AWS Lambda used for post-authentication workflows.
• FHIR-Based Data Layer
  AWS HealthLake was adopted for storing structured health data, with Amazon Athena enabling real-time querying in a SQL-like interface for accessibility.
• Observability and Notifications
  Amazon CloudWatch and SNS were configured for comprehensive logging and proactive alerting to support fault detection and ongoing system health monitoring.

The AWS services selected offered the right balance of scalability, automation, and compliance. Fargate removed infrastructure complexity; Cognito provided robust identity management; and HealthLake brought native support for healthcare data. Together, these services formed a resilient foundation that’s easy to evolve over time.

The modernised architecture resolved key bottlenecks and delivered a more reliable, manageable system aligned with AWS best practices.

• Transitioned from monolith to microservices architecture
• CI/CD pipelines reduced deployment time and manual errors
• Improved observability across all services and environments
• FHIR-compliant data layer enables fast, structured access to clinical data

Stronger business value and client experience

Beyond the technical improvements, Interway is now better positioned to serve clients, pursue growth, and build trust in regulated markets.

• Reduced time to market for healthcare updates
• Increased platform scalability to support future products
• Enhanced security and compliance with healthcare standards
• Lower operational overhead—more time for innovation

The result is a more agile, future-ready business with a solid cloud foundation. Furthermore, as Interway continues to grow its healthcare and financial offerings, several key priorities have come into focus:

1. Platform Expansion. Exploring how the new infrastructure can support additional services across multiple domains.
2. Continuous Optimisation. Refining pipelines, authentication flows, and cloud architecture as team needs evolve.
3. Innovation Enablement. Laying the groundwork for future analytics, AI integration, and new AWS capabilities.

Pragmatic Cloud Transformation for Regulated Industries

A key takeaway from this case is that digital transformation doesn’t have to be disruptive to be effective. By focusing on practical, modular upgrades—containerisation, automation, identity, and data handling—Interway achieved a secure, scalable platform without overhauling its entire product.
