Layer detail

01 / 07

Layer 01 · Visible

Interface and user experience

The point of contact between people and the system.

  • Screens, forms, and dashboards
  • Navigation, search, and filters
  • Visualization and feedback
  • Accessibility and responsive design
  • Loading, error, and recovery states
  • Performance and compatibility

Role Turn internal complexity into a clear, usable experience.

Layer 02 · Control

Identity, authentication, and authorization

  • ERP, CRM, payments, email, and messaging
  • Errors, concurrency, and idempotency

Role Execute reliably what the interface requests.

Layer 05 · Memory

Data and information

Preserves the permanent record on which the system operates.

  • Data model and databases
  • Integrity and consistency
  • History, auditing, and traceability
  • Search and indexing
  • Migration and data quality
  • Retention, backup, and recovery

Role Keep information accurate, available, and verifiable throughout its lifecycle.

Layer 06 · Technical foundation

Security and infrastructure

Supports and protects every layer of the system.

  • Servers, cloud, and storage
  • Networks, DNS, TLS, and firewalls
  • Secret and certificate management
  • Encryption in transit and at rest
  • Environments, scalability, and availability
  • Vulnerabilities and incident response

Role Provide a secure, isolated foundation sized for the operation.

Layer 07 · Continuity

Quality, operations, and continuity

Makes it possible to deploy, observe, maintain, and recover the system.

  • Testing and version control
  • Deployments, migrations, and rollback
  • Monitoring, metrics, logs, and alerts
  • Backups and disaster recovery
  • Support, maintenance, and updates
  • Privacy, auditing, and compliance

Role Keep the system reliable and able to evolve without losing continuity.

↕ Security, quality, and observability extend across every layer.
