Multi-Tenant Architecture

1. Introduction

Multi-tenant architecture is a software architecture pattern that serves multiple tenants or clients using a single instance of the application. It is widely used in SaaS (Software as a Service) applications, where a single application serves multiple customers while providing data isolation and security.

2. Key Concepts

3. Types of Multi-Tenant Architecture

• Single Database, Shared Schema
• Single Database, Separate Schemas
• Multiple Databases

4. Best Practices

• Implement strong authentication and authorization mechanisms.
• Use encryption for sensitive data.
• Design scalable and modular architecture.
• Monitor performance and resource usage across tenants.

5. Code Example

class Tenant {
    constructor(id, name) {
        this.id = id;
        this.name = name;
        this.data = [];
    }
}

class MultiTenantSystem {
    constructor() {
        this.tenants = {};
    }

    addTenant(tenant) {
        this.tenants[tenant.id] = tenant;
    }

    getTenantData(tenantId) {
        return this.tenants[tenantId] ? this.tenants[tenantId].data : null;
    }
}

// Usage
const system = new MultiTenantSystem();
const tenant1 = new Tenant(1, "Tenant A");
system.addTenant(tenant1);
