SaaS-Optimized Cloud Platform

Xelon provides the infrastructure foundation for SaaS and software platform companies. Whether you're building vertical SaaS, developer tools, or enterprise platforms, Xelon delivers the performance, security, and economics required for sustainable growth.

Core SaaS Infrastructure:**

• Managed Kubernetes: Multi-tenant microservices with namespace isolation (CNCF-certified K8s 1.28+)

• Managed Databases: PostgreSQL, MySQL, MongoDB with read replicas for multi-tenant data

• API Gateway: Kong, Traefik, or custom API gateways with rate limiting and authentication

• Object Storage: S3-compatible storage for user uploads, exports, backups (zero egress)

• Message Queues: RabbitMQ, Kafka for async job processing and event-driven architectures

• Caching: Redis clusters for session management, rate limiting, feature flags

Multi-Tenancy Patterns:**

• Database per Tenant: Complete data isolation with dedicated PostgreSQL/MySQL instances per customer

• Schema per Tenant: Shared database with per-tenant schemas (cost-efficient for SMB SaaS)

• Shared Schema: Single schema with tenant_id column (highest density, lowest cost)

• Kubernetes Namespaces: Per-tenant namespaces with RBAC and network policies

Developer Experience:**

• GitOps: ArgoCD or Flux for declarative infrastructure and application deployments

• CI/CD: GitLab CI, GitHub Actions, CircleCI integration with Kubernetes deployments

• Infrastructure-as-Code: Terraform provider for automated provisioning

• Observability: Prometheus, Grafana, Loki, Jaeger for metrics, logs, and tracing

• API-First: RESTful API with OpenAPI 3.0 for programmatic resource management

Security & Compliance:**

• Data Residency: 100% Swiss data for GDPR/FADP compliance (no US CLOUD Act exposure)

• Tenant Isolation: Network policies, RBAC, dedicated databases for enterprise customers

• Encryption: AES-256 at rest, TLS 1.3 in transit, customer-managed keys (BYOK)

• SSO Integration: SAML 2.0, OAuth 2.0, OIDC for enterprise customer authentication

• Audit Logging: Comprehensive audit trails for SOC 2, ISO 27001 compliance

Cost Economics for SaaS:**

• Zero Egress Fees: API responses, data exports, backups have no bandwidth charges

• Predictable Pricing: Compute + storage only (no hidden load balancer data fees, NAT gateway fees)

• Per-Customer Economics: Lower infrastructure costs = higher gross margins (60-80% vs. 40-50% on AWS)

• Growth Scaling: Linear cost scaling without egress fee explosions at high traffic

SaaS Platform Examples:**

• Vertical SaaS: Industry-specific platforms (healthcare, legal, fintech) with Swiss data residency

• Developer Tools: CI/CD platforms, monitoring SaaS, API platforms with high API traffic

• Analytics Platforms: Business intelligence, data visualization with large export volumes

• Collaboration Tools: Project management, CRM, HRIS with file storage and sharing

Cost Comparison (Growing SaaS - 100 customers, 5 TB egress/month):**

• AWS (EKS + RDS + egress): CHF 600 K8s + CHF 400 database + CHF 450 egress = CHF 1,450/month

• Google Cloud (GKE + Cloud SQL): CHF 550 K8s + CHF 350 database + CHF 550 egress = CHF 1,450/month

• Xelon: CHF 400 K8s + CHF 300 database + CHF 0 egress = CHF 700/month ✅ (52% cheaper)
