Single-Tenant vs Multi-Tenant Architecture

Meeting Agenda

A comprehensive comparison of architectural approaches to inform our platform strategy

Single-Tenant

Dedicated infrastructure per customer with maximum isolation and customization

High Isolation Customizable

Multi-Tenant

Shared infrastructure with logical separation optimized for operational efficiency

Cost Effective Scalable

High-Level Architecture Comparison

Key differences between single-tenant and multi-tenant approaches

Criteria	Single-Tenant	Multi-Tenant
Data Isolation	Physical (DB per tenant)	Logical (Centralized DB)
Scalability	Linear (DB per customer)	Horizontal (DB-rows per usage)
Operational Effort	High (per-tenant ops)	Low (centralized ops)
Customization	Flexible & Easy	Controlled
Cost Model	High fixed baseline	Shared & optimized
Onboarding Speed	Slow (infra provisioning)	Instant (self-service)
Long-Term Growth	Painful at scale	Designed for scale

Key Insight: Both models are secure and valid — the primary difference is operational efficiency at scale. Multi-tenant offers better resource utilization while single-tenant provides stronger isolation.

Hybrid Strategy: The Optimal Middle Ground

Balancing flexibility, scalability, and isolation requirements

Hybrid Approach (Recommended)

Start with Multi-Tenant Architecture for standard customers
Design for isolation at application and data layers
Allow DB-per-tenant migration path when needed (with consistent codebase)
Implement tenant-aware routing and data partitioning from day one

Customer Segmentation Strategy

Customer Type	Architecture	Rationale
SMB / Standard	Multi-Tenant	Cost-effective, quick onboarding, shared resources
Enterprise / Regulated	Single-Tenant	Compliance requirements, data sovereignty, custom needs
Premium / Reseller	Dedicated DB/Cluster	Performance isolation, white-labeling, billing separation

Enterprise customers (including resellers) purchase service from us and provide it to others. They often require dedicated infrastructure for compliance, performance, or branding reasons.

Executive Summary & Recommendation

Strategic direction for our platform architecture

Single-tenant architecture addresses immediate isolation concerns but creates operational complexity at scale. Multi-tenant architecture is designed for efficiency and growth. Starting with a multi-tenant foundation while maintaining a hybrid escape hatch gives us scalability without sacrificing control.

Advantages of Hybrid

Optimized resource utilization
Flexible customer segmentation
Simplified operations at scale
Future-proof architecture

Implementation Path

Phase 1: Multi-tenant MVP
Phase 2: Isolation enhancements
Phase 3: Hybrid capability
Phase 4: Enterprise features

Decision Point

We recommend adopting a multi-tenant first approach with built-in capabilities for single-tenant isolation where required. This balances time-to-market, operational efficiency, and future flexibility.
