Modern software architecture
Scalable, maintainable, and high-performance architectures for your digital projects
Software architecture determines a project's ability to evolve, scale, and remain maintainable over time. A poor architectural choice can doom a project to permanent refactoring or premature obsolescence.
Our expertise covers modern architectures: headless decoupling frontend and backend, microservices for complex systems, API-first for multi-channel integration. We apply the principles of Clean Architecture and Domain-Driven Design for solid foundations.
This page presents our approach to software architecture and the patterns we use to design performant, scalable, and maintainable systems.
Headless Architectures
Frontend/Backend Decoupling
Headless architecture separates content management from its presentation:
- Headless CMS: Directus, Strapi, Contentful
- Modern frontends: Astro, Next.js, Nuxt
- Flexibility: same content on web, mobile, IoT
- Performance: static pages, SSG, ISR
Benefits
- Freedom of choice in frontend technologies
- Independent scaling of each component
- Enhanced security (reduced attack surface)
- Optimized user experiences
API-First Architecture
API Design
- REST: standard and documented RESTful APIs
- GraphQL: flexible and optimized queries
- OpenAPI/Swagger: automatic documentation
- Versioning: evolution without breaking changes
Best Practices
- Authentication and authorization (JWT, OAuth2)
- Rate limiting and protection
- Intelligent caching
- Consistent error handling
Our Process
- Needs analysis: understanding context and constraints
- Design: architecture design and documentation
- Validation: review and adjustments
- Implementation: architecture-guided development
- Documentation: ADRs and technical guides
Architectural Patterns
Clean Architecture
- Separation of concerns
- Inverted dependencies
- Maximum testability
- Framework independence
Domain-Driven Design (DDD)
- Business modeling
- Bounded contexts
- Ubiquitous language
- Aggregates and entities
Event-Driven Architecture
- Asynchronous communication
- Service decoupling
- Horizontal scalability
- Failure resilience
Technologies and Tools
Backend
- TypeScript: strong typing and maintainability
- Node.js: performance and ecosystem
- PostgreSQL: robust database
- Redis: cache and sessions
Infrastructure
- Docker: containerization
- Kubernetes/Coolify: orchestration
- CI/CD: deployment automation
- Monitoring: complete observability
Backup Services - Custom Solutions
The existing system audit analyzes your current backups: evaluation of existing solutions, identification of vulnerabilities, recommendations for improvement, and estimation of optimization costs. We start from your actual situation.
The setup includes custom backup architecture, configuration and deployment, integration with your existing infrastructure, and comprehensive documentation. A backup solution that adapts to your constraints.
The OVH catalogue also includes Public Cloud (scalable instances, managed databases), S3-compatible Object Storage for your media and large files, and advanced network services: failover IP, vRack (private network), permanent anti-DDoS protection.
These services scale with your project growth without complex migration.
OVH infrastructure is built on a global proprietary network with high availability and recognised certifications (ISO 27001, HDS for health, SOC). French datacenters benefit from redundant power and very high-speed fibre connectivity.
This reliability allows us to guarantee our clients stable, performant hosting.
Source/sync workflow and data management
The source/sync workflow is the heart of IWHWI. For each content type, the framework provides commands: new (create an empty aXXXX folder), source create (push to Directus), source update (update), sync (pull from Directus), source set (copy between spaces). Each operation is atomic and traceable.
This cycle keeps local files and Directus in sync at all times.
Data files are in JSON format, stored in numbered folders (aXXXX) and versioned in Git. Each file is timestamped: default files have a fixed timestamp (1970), directus and ia files carry the actual creation date. Auto mode automatically selects the latest files across all spaces.
This organisation allows comparing, restoring and auditing every content version.
Automatic translation is built into the workflow. IWHWI detects missing content per language and translates via Gemini or Google Cloud Translate. Translations are generated in the ia space, reviewed, then pushed to Directus. The system supports five languages (fr-FR, en-US, es-ES, de-DE, it-IT) and is extensible.
Translation becomes an automated step in the content pipeline, not a manual task.
Choosing our software architecture expertise means benefiting from:
- an architecture adapted to your real constraints, not oversized,
- solid foundations for a serene evolution of the project,
- proven patterns applied with pragmatism,
- clear technical documentation for maintainability.
You get an architecture that supports your growth instead of hindering it.
