Future-Proof Your Web App: Upgrade .NET Framework to .NET 9 Serverless & Angular 18

challenges

A financial services company faced significant challenges with its legacy .NET Framework-based web application, which was hosted on Azure Virtual Machines (VMs). The system suffered from performance bottlenecks, high operational costs, and limited scalability. To modernize their infrastructure and future-proof their application, they migrated to a serverless architecture using Azure Functions (.NET 9) and an Angular 18 front-end. This transition not only reduced costs but also enhanced system performance, security, and scalability.

Challenges in the Existing Infrastructure

  1. Monolithic Architecture Leading to Scalability Issues
  2. High Operational Costs Due to VM-Based Hosting
  3. Outdated .NET Framework Codebase

Proposed Serverless Solution

To overcome these challenges, we implemented a serverless-first approach leveraging Azure Functions (.NET 9) for backend services and Angular 18 for the frontend UI.

Serverless Migration with Azure Functions (.NET 9)

  • Microservices-based FaaS – The monolithic backend was broken into microservices using Azure Functions.
  • Event-driven execution – Functions only execute when triggered, reducing idle compute time and costs.
  • Durable Functions – Used for long-running workflows like guest check-in automation and payment processing.

Replacing Windows Task Scheduler with Serverless Job Execution

  • Azure Functions Timer & Queue Triggers replaced Windows Task Scheduler for job execution.
  • Auto-scaling capabilities ensured high availability during traffic spikes.
  • Azure Storage Queues & Service Bus were implemented for reliable, event-driven job processing.

Cold Start Optimization

  • Azure Premium Plan enabled always-on instances, reducing cold start latency.
  • Pre-warming strategies using HTTP warm-up triggers kept key functions active.

Database Optimization for a Stateless Serverless Model

  • Implemented connection pooling using Azure SQL Managed Identity for secure and efficient database access.
  • Azure Cache for Redis was added to store frequently accessed data, reducing database query loads.

Frontend Modernization with Angular 18

  • Implemented Angular Universal (SSR) to improve SEO and page load times.
  • Used Progressive Web App (PWA) features for offline access & enhanced user experience.
  • NgRx state management ensured efficient data flow between frontend & backend.

Improved Monitoring & Observability

  • Azure Application Insights provided real-time performance monitoring.
  • Azure Log Analytics & Distributed Tracing enabled better debugging and error tracking.
  • Automated alerts helped detect and resolve anomalies before impacting users.

Results & Business Impact

Migrating to Azure Functions and Queues boosted job processing speed by 50%, while switching to a serverless model cut infrastructure costs by 60%. The system scaled instantly during peak booking seasons, and modern authentication (Azure AD B2C) strengthened security. Real-time monitoring reduced downtime by 40%, and a microservices-based architecture accelerated CI/CD deployments.
