The Challenge: Why Multi-Tenant SaaS is Complex for Agencies

For digital agencies and dev shops managing multi-tenant SaaS applications, Kubernetes presents both an opportunity and a challenge. While Kubernetes provides flexibility and scalability, the operational complexity of isolating clients, managing deployments, handling networking, and ensuring security can be overwhelming.

Common Challenges Agencies Face When Running Multi-Tenant SaaS on Kubernetes

• Client isolation: Ensuring each tenant has dedicated resources without interference.
• Networking & service discovery: Routing traffic securely between tenant-specific services.
• Managing secrets & environment variables: Keeping each client's sensitive data secure.
• Scaling infrastructure: Ensuring apps automatically scale while keeping costs manageable.
• Custom domain management: Mapping unique domains per tenant without manual configuration.

This is where Convox simplifies multi-tenant SaaS hosting—by automating the hardest parts while keeping full Kubernetes power when needed.

How Convox Makes Multi-Tenant SaaS Deployments Easy

Convox abstracts Kubernetes complexity, allowing agencies to focus on client work instead of infrastructure headaches. Here's how Convox enables agencies to deploy multi-tenant SaaS effortlessly:

1. Client Isolation: Apps & Racks for Secure Environments

Each Convox App runs in its own Kubernetes namespace, ensuring complete isolation between clients.

• Agencies can deploy a separate app per tenant.
• For larger clients, agencies can provision dedicated Racks (regional clusters).
• Isolation at the networking, storage, and environment level prevents cross-tenant conflicts.

🔹 Example: Deploying a separate app per tenant

services:
  tenant1:
    build: .
    port: 3000
    domain: tenant1.example.com
  tenant2:
    build: .
    port: 3000
    domain: tenant2.example.com

💡 Each tenant's app runs in its own namespace, ensuring complete isolation.

2. Automated Load Balancing & Service Discovery

Manually setting up Ingress, DNS, and load balancing for multiple tenants is complex. Convox automates it all:

• Built-in HTTPS Load Balancer: Automatically routes traffic to the correct tenant.
• Internal Service Discovery: Services within a Rack can securely communicate without custom networking.
• Multi-Rack Communication: Agencies with tenants in different regions can enable private rack-to-rack communication.

🔹 Example: Internal service discovery between tenant microservices

services:
  api:
    internal: true
    port: 5000
  web:
    port: 3000

💡 The web service can access api securely at http://api.myapp.convox.local:5000 without exposing it publicly.

3. Managing Secrets & Environment Variables Per Tenant

Each Convox app has its own environment variables, keeping tenant secrets separate.

• Agencies can manage database credentials, API keys, and sensitive data per tenant.
• Secrets are never stored in the codebase and are injected at runtime.

🔹 Example: Setting environment variables per tenant

$ convox env set DATABASE_URL=postgres://tenant1-db -a tenant1
$ convox env set DATABASE_URL=postgres://tenant2-db -a tenant2

💡 Each tenant app gets its own environment, preventing accidental credential leaks.

4. Scaling & Performance Optimization for Agencies

Multi-tenant SaaS applications need dynamic scaling to handle varying client workloads.

• Convox supports autoscaling per tenant app.
• Agencies can set CPU/memory-based scaling policies.
• Dedicated Racks ensure performance for high-value clients.

🔹 Example: Autoscaling settings per tenant

services:
  web:
    scale:
      count: 2-10
      targets:
        cpu: 50
        memory: 75

💡 Each tenant scales independently, ensuring cost efficiency & performance stability.

5. Seamless Custom Domain & SSL Management

🔹 Example: Assigning unique domains per tenant

services:
  tenant1:
    domain: app.tenant1.com
  tenant2:
    domain: app.tenant2.com

💡 No need for manual DNS or SSL setup—Convox provisions everything automatically.
