Overview

NOUS CMS is a multi-tenant museum content management platform serving 50+ cultural institutions worldwide. The microservices architecture combines an Angular WebCMS frontend with a Node.js REST API backend, supported by five specialized services handling community engagement, synchronization, translation, payments, and device management.

The platform manages 100,000+ content items per tenant with a four-level hierarchical structure (Exhibitions → Tours → Stations → Content Items), distributing content across web applications, iOS/Android native apps, and kiosk systems in 20+ languages including right-to-left scripts.

The Challenge

Museums faced overwhelming complexity managing thousands of artifacts, exhibitions, and multimedia content across multiple platforms (web, native mobile apps, kiosk systems) in 20+ languages including right-to-left scripts. Curatorial staff spent 60% of their time on manual content management tasks using fragmented systems. Content updates took days to propagate across hundreds of devices. Multi-language management required external translation services with 5-day turnarounds.

The platform also required a zero-downtime migration from Angular 6 to 20 and Node.js 18 to 24, offline-capable SQLite database generation for native apps, and automated media processing for thousands of images and videos across multi-provider cloud storage.

The Solution

Built a sophisticated microservices architecture with Angular 20 WebCMS and Node.js 24 backend, supported by five specialized microservices. MongoDB provides flexible document storage for hierarchical museum content. Keycloak handles multi-tenant authentication with UUID-based tenant separation ensuring complete data isolation.

Key innovations include automated media processing pipeline with multi-provider storage (Azure Blob, AWS S3), SQLite sync service generating offline-capable databases for native mobile apps, simultaneous multi-language editing in 20+ languages, and type-driven content configuration supporting images, videos, audio, and 3D models. The zero-downtime migration from Angular 6→20 was achieved through phased upgrades.

Results

The platform achieved 70% reduction in content management operational costs, 85% increase in visitor engagement, and reduced content update cycles from multiple weeks to 30 minutes–2 hours. 50+ museums now serve thousands of daily visitors globally through a single platform. The multi-language system reduced translation management time by 60%, and automated media processing handles 75% of tasks that previously required manual effort.
