Now in Part 3, we turn to the solution: What if you didn’t have to abandon your existing stack, but could augment it with a purpose-built control plane, one that handled tenant lifecycle, deployment orchestration, and multi-cloud complexity out of the box?

Imagine a data analytics SaaS startup, “DataCo”, that wants to build Redis SaaS as an example. They use Argo CD to deploy their analytics application (a set of microservices + some Spark jobs) onto the EKS cluster.

Modern platform engineering teams often assemble “DIY” control planes for their data products using open-source building blocks: Kubernetes for the runtime, Terraform for infrastructure provisioning, and Argo CD for continuous deployment. This stack promises cloud-agnostic flexibility and full control. But as many CTOs and platform VPs have learned, stitching these tools together into a robust control plane is hard.
