Most SaaS platforms today leverage multi-tenancy to efficiently serve thousands of customers. This architecture allows multiple tenants (organizations or users) to share a single instance of the software while keeping their data isolated and secure. Multi-tenancy has become a standard architecture for SaaS applications, enabling businesses to serve multiple clients efficiently. 

However, as SaaS companies strive to differentiate themselves, customer-facing analytics—where end-users directly interact with data insights—has emerged as a critical feature. Unlike traditional internal analytics, customer-facing analytics focuses on delivering actionable insights directly to the end-user through intuitive dashboards embedded within the SaaS product.

While multi-tenancy simplifies infrastructure management and reduces costs, implementing it for customer-facing analytics introduces unique challenges. These challenges stem from the need to balance scalability, security, and customization while ensuring a seamless user experience.

This blog will talk about the different types of multi-tenant analytics and how you can implement them for your SaaS business.

What is Multi-Tenant Analytics, and Why is It Important?

Multi-tenant analytics refers to a system where a single analytics platform serves multiple tenants, ensuring strict data isolation while delivering personalized insights. Unlike single-tenant systems, where each client has a dedicated instance, multi-tenant analytics enables shared infrastructure and resources.

Key Benefits of Multi-Tenant Analytics:

• Cost Efficiency: Shared infrastructure reduces operational costs.
• Scalability: Onboarding new tenants is seamless.
• Enhanced User Experience: Customers gain real-time access to tailored dashboards and reports.
• Faster Deployment: Centralized updates benefit all tenants simultaneously.
• Streamlined Maintenance: A single system simplifies updates and troubleshooting.

Why Building Multi-Tenant Analytics is Challenging

While multi-tenancy as an architecture is well understood when it comes to SaaS application management, extending it to analytics platforms introduces significant complexities. Key challenges include:

Data Isolation 

Ensuring that each tenant’s data is securely isolated is critical. A single misstep in query logic or permissions can expose sensitive data across tenants. Implementing row-level security or schema isolation adds to development complexity.

Replication of Application Tenancy

Replicating the same level of data isolation and segregation found in the SaaS application for analytics systems requires intricate backend configurations. Developers often struggle to match the tenancy structure seamlessly.

Self-Service Capabilities

Enabling tenants to perform self-service reporting like exploring data, customizing dashboards, and generating reports independently demands advanced role-based access controls and intuitive user interfaces.

Performance Management

Analytics platforms often face unpredictable traffic patterns, as tenants generate reports or query data independently balancing resource allocation to prevent “noisy neighbor” effects is a complex task.

For SaaS businesses, multi-tenant analytics isn’t just a feature—it’s a competitive differentiator that enhances your ability to improve user experience and establish customer trust.

Types of Data Models in Multi-Tenant Analytics

Multi-tenant analytics relies on different data models to manage tenant data securely and efficiently. Each model offers varying levels of complexity, cost, and scalability. 

1. Shared Database, Shared Schema

In this model, all tenants share the same database and schema. Tenant-specific data is stored in shared tables, differentiated by a unique identifier (e.g., client_id).

Advantages

• Cost-Effectiveness: Maximizes resource sharing, reducing infrastructure costs.
• Ease of Maintenance: Updates to the schema apply universally to all tenants.
• Scalability: Suitable for serving a large number of tenants with minimal resources.

Challenges

• Noisy Neighbor Effect: High activity from one tenant can impact others.
• Limited Customization: All tenants must conform to the same schema structure.

Use-case

A SaaS e-commerce platform serving multiple retailers could use this model. Each retailer (tenant) shares the same database tables for products, orders, and customers but is identified by a client_id.

Sample SQL

CREATE TABLE products (

    id SERIAL PRIMARY KEY,

    name TEXT,

    price NUMERIC,

    client_id INT

);

‍

2. Shared Database, Multiple Schemas

In this model, all tenants share a single database instance, but each tenant has its own schema. This provides better data isolation while leveraging shared infrastructure.

Advantages

• Improved Data Isolation: Each tenant’s data resides in its own schema.
• Moderate Customization: Allows minor schema-level adjustments for individual tenants.
• Efficient Resource Use: Balances isolation and cost efficiency.

Challenges

• Complex Management: Requires more effort to maintain multiple schemas.
• Scaling Limitations: As the number of schemas grows, performance may degrade.

Usecase

A SaaS healthcare platform could use this model to comply with HIPAA regulations by isolating patient data for hospitals in separate schemas within the same database.

Sample SQL

-- Schema for Tenant A

CREATE SCHEMA tenant_a;

CREATE TABLE tenant_a.patients (

    id SERIAL PRIMARY KEY,

    name TEXT,

    dob DATE

);

‍

-- Schema for Tenant B

CREATE SCHEMA tenant_b;

CREATE TABLE tenant_b.patients (

    id SERIAL PRIMARY KEY,

    name TEXT,

    dob DATE

);

‍

3. Multiple Databases, Shared Schemas (Hybrid Tenancy)

This model assigns each tenant its own dedicated database and schema (with the same schema structure). It offers the highest level of isolation and security but comes at a higher cost.

Advantages

• Maximum Isolation: Each tenant operates independently, eliminating cross-tenant interference.
• Customization Flexibility: Tenants can have unique configurations or customizations.
• Enhanced Security: Ideal for industries requiring strict compliance (e.g., finance or defense).

Challenges

• High Costs: Requires more resources to maintain separate databases.
• Complex Management: Scaling involves provisioning new databases for each tenant.

Usecase

A financial SaaS platform serving banks might use this model to ensure compliance with PCI DSS by providing each bank with its own database instance.

Sample Code:

# Example Database Structure

Database 1: bank_a_db

Schema: transactions

Database 2: bank_b_db

Schema: transactions

Implementing Multi-Tenancy with Databrain

When it comes to the hybrid tenancy most data analytics tools don’t provide capabilities to support a similar architecture bespoke. Implementation of analytics with this architecture with such BI tools becomes extremely complicated and requires tailored setup. 

This is where DataBrain stands out with its robust capabilities for multi-tenancy. It allows multiple databases to be connected to a single dashboard, with each database representing a dedicated client. This makes it an excellent choice for environments where each client operates in their own isolated database but requires access to consistent analytics.

Showcase: Implementing Hybrid Tenancy using DataBrain

DataBrain’s Multi-tenancy allows setting up of:

• Multiple Databases

The feature allows connecting to multiple databases from a single dashboard. This setup is characteristic of database-level tenancy, where each customer has its own dedicated database.

• Shared Schema

All connected databases must share the same schema structure, meaning they have identical column names, and data types. This uniformity is essential for the dashboard's functionality, allowing seamless switching between data sources without errors.

• Shared Dashboard

When you connect to different data sources, the dashboard automatically updates its metrics to reflect the data from the selected data source. This ensures that users see the most current information without needing to reload or duplicate dashboards. This feature is particularly useful for implementations where each client operates with their own database (e.g., one database per client).

‍

Pre-requisites:

1. Uniform Schema Across Data sources

All connected data sources must share a consistent schema structure. This includes identical table names, column names, and data types. Any discrepancies in the schema can lead to query errors when the dashboard attempts to access data based on user selections.

2. Same Type of Data sources

It is crucial that all connected data sources are of the same type (e.g., all should be PostgreSQL or all MySQL). Mixing different types of data sources, such as combining MSSQL with PostgreSQL, is not supported. This requirement ensures that query execution remains compatible across the backend systems.
