LEGAU

The five-layer industrialised foundation that ensures you never start from scratch.

LEGAU is the shared backbone of every BETC Fullsix digital project: a five-layer architecture (L0 to L4) that pools infrastructure, shared services and reusable business code across all engagements. Each new project inherits a battle-tested foundation, already audited and already running in production elsewhere, and can go live in weeks rather than months.

It is not another framework to learn: it is the same technical spine running every headless site, every conversational platform and every internal tool we build. A developer joining a LEGAU project finds the same branching conventions, the same CI/CD pipeline, the same observability stack - only the L4 layer changes from one project to the next.

Never from scratch

Layers L0 to L2 are shared across every project. Kubernetes infrastructure, Redis/PostgreSQL/S3/MinIO services, Keycloak SSO - all already running and already proven on other engagements. Client-specific code (L3/L4) is the only genuinely new work per project, which cuts technical risk and time-to-production accordingly.

Full reversibility

Open code, industry standards (Helm, ArgoCD, Kubernetes) and zero proprietary lock-in. No closed PaaS, no in-house data format: hand the project over to another agency or take it in-house tomorrow, and it is portable, documented and readable by any DevOps team that knows Kubernetes.

Industrialised delivery

CI/CD with semantic-release, automatic versioning and reproducible deployments. One identical pipeline covers every stage - code quality, tests, security, performance - from feature branch to BSO production, with a human sign-off gate before every release.
