Architecture Overview

The Enterprise Development Platform consists of several key components working together to provide a comprehensive development and deployment environment.

Key Components

OTC Foundry - Central management and orchestration layer
Per-Tenant EDP - Isolated development environments for each tenant
FaaS Environment - Function-as-a-Service deployment targets on Open Telekom Cloud
Cloud Services - Managed services including databases, storage, and monitoring

Deployment Environments

Development Environment (*.t09.de) - For platform team development and testing
Production Environment (*.buildth.ing) - For production workloads and tenant services

Component Details

The interactive diagram above shows the relationships between different components and how they interact within the system architecture. You can explore the diagram by clicking on different elements to see more details.

Infrastructure Components

Kubernetes Clusters - Container orchestration using OTC CCE (Cloud Container Engine)
ArgoCD - GitOps continuous deployment and application lifecycle management
Forgejo - Git repository management and CI/CD pipelines
Observability Stack - Monitoring (Prometheus, Grafana), logging (Loki), and alerting

Security and Management

Keycloak - Identity and access management (IAM)
OpenBao - Secrets management (Hashicorp Vault fork)
External Secrets Operator - Kubernetes secrets integration
Crossplane - Infrastructure as Code and cloud resource provisioning

Developer Experience

Backstage - Internal developer portal and service catalog
Forgejo Actions - CI/CD pipeline execution
Development Workflows - GitOps-based inner and outer loop workflows

Setup and Maintenance

To update or modify the architecture diagrams:

Edit the .c4 files in resources/likec4/

Regenerate the webcomponent:

cd resources/likec4
npx likec4 codegen webcomponent \
  --webcomponent-prefix likec4 \
  --outfile ../../static/js/likec4-webcomponent.js

Commit both the model changes and the regenerated JavaScript file
