Cloud-Native Architecture Patterns for Modern SaaS Platforms

Dibya Ranjan Mishra· 12 min

Multi-tenant isolation, cell-based architectures, and platform engineering — patterns I've used to scale SaaS from MVP to enterprise.

Modern SaaS lives on Kubernetes, service meshes, and managed data planes. We unpack tenancy models (silo, pool, bridge), cell-based architectures, and how platform engineering converts infrastructure into developer leverage.

This is a working note — expect iteration as the field and our practice evolve. If you have feedback, counterexamples, or want to compare implementation notes, reach out.

Key takeaways

  • Choose tenancy model before product-market fit hardens.
  • Cells contain blast radius and unlock per-tenant SLOs.
  • Platform teams accelerate product teams only with paved roads.
