Multi-Tenant Mobile Application Platform Modernization on Microsoft Azure

Executive Summary

A North American digital services organization partnered with atQor to modernize a legacy mobile application platform built on outdated frameworks and manual release processes.

atQor designed and delivered a cloud-native, multi-tenant CMS-driven platform on Microsoft Azure that enabled business users to independently manage content, features, and branding for multiple community-specific mobile applications—without ongoing dependency on technical teams.

The solution established a scalable, microservices-based foundation that significantly improved agility, governance, and innovation velocity.

The customer operates a multi-community digital engagement platform, delivering mobile applications to distinct user groups, each with unique branding, content, and feature requirements.

Key characteristics:

  1. Multiple communities with independent mobile apps
  2. Legacy .NET Framework and Apache Cordova–based architecture
  3. Heavy reliance on technical teams for content and app updates
  4. Need for faster customization, releases, and innovation
  5. Desire to reduce operational overhead while improving scalability

Business Challenges

The existing platform faced several limitations:

  1. Legacy Technology Constraints
    Applications were built on older frameworks, limiting scalability and flexibility.

  3. Fragmented App Management
    Each community required tailored artifacts, but lacked a centralized management model.
  4. Slow Release Cycles
    Manual intervention slowed updates and app store deployments.
  5. Limited Future Readiness
    The architecture did not easily support integration with new services or channels.
