SaaS Operating System

What is the SaaS Operating System?

The CloudARK SaaS Operating System is an opinionated, pre-integrated set of Kubernetes-native components that software teams need to run SaaS and managed services reliably in production.

Instead of assembling, securing, and operating dozens of open-source tools on your own, CloudARK delivers a curated SaaS foundation that works out of the box — and evolves with you as your SaaS matures.

Think of it as the operating layer between Kubernetes and your application — purpose-built for SaaS.

Why teams struggle without a SaaS OS

Most teams underestimate what it takes to run SaaS at scale:

Stitching together DNS, certs, ingress, observability, and cost tooling
Keeping versions compatible across clusters
Managing upgrades without breaking tenants
Creating a consistent operational model across environments
Supporting both internal platforms and external customer-facing SaaS

The result is slow launches, brittle operations, and high cognitive load on platform teams. The SaaS Operating System exists to remove that friction.

What's included today

The SaaS Operating System currently includes the following core building blocks, curated and validated to work together:

🔐 Certificate & Traffic Management

Cert Manager – Automated SSL certificate lifecycle
NGINX Ingress – Load balancing and traffic routing

🌐 DNS Automation

External DNS – Automated DNS management across environments and clouds

💰 Cost Visibility

OpenCost – Kubernetes-native spend tracking and cost insights

💾 Backup & Restore

Velero – Backup and restore for Kubernetes workloads and cluster resources

🧩 Multi-Tenancy Foundation

KubePlus – Kubernetes-native multi-instance, per-tenant lifecycle management

All components are: Open source, Version-aligned, Pre-integrated and Cloud-agnostic.

What makes this more than “just a bundle”

Many teams use these tools individually. The value of the SaaS Operating System is in how they are combined and operated:

Compatibility-tested versions
Opinionated defaults suitable for SaaS and managed services
Clear upgrade and lifecycle strategy
Designed to work with multi-tenant SaaS patterns, not just single-cluster apps

This dramatically reduces time spent on: installation, break/fix, and operational guesswork.

How teams use the SaaS Operating System

What makes this more than “just a bundle”

Teams typically use the SaaS OS to:

Standardize SaaS foundations across environments
Accelerate launch of a managed service
Reduce operational risk during early growth
Create a repeatable platform for future services

It can be deployed:

On a single Kubernetes cluster or multiple clusters
On any major cloud provider or on-prem
Incrementally — you don’t need to adopt everything at once

A curated Kubernetes-native foundation for launching managed services and SaaS.
