Scaling

• Independence of resources: Each customer tenant is logically isolated with dedicated database schemas and separate API authentication contexts. Rate limiting prevents any single tenant from monopolising shared resources. Background processing jobs are queued independently per tenant. Cloud infrastructure auto-scales based on demand, with resource quotas ensuring fair allocation. Critical data processing pipelines use isolated compute resources. Performance monitoring tracks per-tenant metrics, enabling proactive intervention before degradation affects other users. Load balancing distributes requests across multiple service instances to prevent hotspots.

Availability and resilience

• Guaranteed availability: The service is hosted in AWS. AWS SLAs apply to the service.
• Approach to resilience: TailPipe is hosted on AWS with multi-availability zone deployment for high availability. Application instances run behind load balancers with automatic health checks and failover. Database services use AWS RDS with automated failover and point-in-time recovery. Data is replicated across availability zones with automated daily backups. The application is stateless, enabling rapid horizontal scaling and instance replacement. Circuit breakers prevent cascade failures when dependent services are unavailable. Infrastructure is defined as code, enabling rapid environment recreation. Monitoring and alerting ensure issues are detected and addressed promptly.
• Outage reporting: Service outages are notified via the Tailpipe website (hosted separately) and email alerts.

Role-based access control restricts administrative functions to users with appropriate scopes. Operations are tenant-isolated using verified tenant IDs from authentication tokens.; ; Support Channels:; Support is provided through authenticated channels linked to verified customer accounts. Staff access customer data only via role-restricted interfaces with audit logging.; ; Cloud Credentials:; AWS uses External ID patterns with least-privilege IAM. Azure uses Managed Identity.

Operational security

• Configuration and change management standard: Supplier-defined controls
• Configuration and change management approach: Configuration Management:; All infrastructure and application configuration is version-controlled in Git. Environment-specific settings are managed through externalised configuration files, with secrets stored in cloud-native vaults (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager). Configuration changes require pull request review and approval before deployment.; ; Change Management:; Changes follow a structured process: development on feature branches, peer code review, automated testing, staged deployment through development, staging, and production environments. All changes are logged with full audit trails. Rollback procedures are documented and tested. Emergency changes follow an expedited review process with retrospective documentation.
• Vulnerability management type: Supplier-defined controls
• Vulnerability management approach: Dependencies are monitored continuously using automated scanning tools (Dependabot, Snyk) integrated into our CI/CD pipeline. Security patches are prioritised based on severity: critical vulnerabilities addressed within 24 hours, high within 7 days, medium within 30 days. Container images are scanned before deployment. Infrastructure undergoes regular vulnerability assessments. Third-party penetration testing is conducted quarterly. All findings are tracked to resolution with root cause analysis. Security advisories from cloud providers, multiple security forums, framework maintainers are monitored and actioned promptly.
• Protective monitoring type: Supplier-defined controls
• Protective monitoring approach: Application and infrastructure logs are collected centrally and retained for 12 months. Real-time alerting monitors for anomalous activity including failed authentication attempts, unusual API usage patterns, and privilege escalation. Cloud-native security services (AWS CloudTrail) track all administrative actions. All access to customer data is logged with user identity, timestamp, and action performed.
• Incident management type: Supplier-defined controls
• Incident management approach: We have pre-defined processes for incident responses. We also practice these at least twice a year to ensure that all staff are familiar with the process.; ; Incidents are reported through two separate systems (this is used in case one were compromised).
• Post-quantum cryptography secure: No

Secure development
