Most migration overruns are not technical failures. They come from cost assumptions that looked reasonable at the start but were never pressure-tested against real workload behavior.
When teams move from OpenStack VM estates to Kubernetes, spend can become more predictable, but only if financial modeling starts early. If your workloads run on OneCloudPlanet, this guide gives you a practical way to plan migration without budget shocks.
Start with a clean baseline
Use at least 90 days of historical data, not one invoice. Include compute, storage, network, licensing, and platform operations time.
This baseline is your reference for every decision that follows. Without it, savings discussions quickly turn into assumptions.
Model migration as scenarios, not as one estimate
Build three scenarios before implementation starts:
• baseline migration of current workloads,
• growth case (+20–30% traffic and storage),
• peak case for seasonal or campaign spikes.
This keeps planning realistic and prevents “unexpected” overspend that was actually predictable.
Account for container overhead from day one
Kubernetes introduces costs that are easy to underestimate in early planning: control plane resources, ingress, observability, CI/CD pipelines, and duplicated non-production environments.
For platform design patterns, align with our Kubernetes operations article.
Add governance before migration waves
Define ownership, tags, and budget alerts upfront. Automate non-production schedules and retention for snapshots and logs.
If infrastructure is managed as code, formalize these controls with Terraform so cost hygiene is repeatable.
Hence
OpenStack-to-Kubernetes migration should be treated as a financial and operational program, not only as a platform upgrade. A clear baseline, realistic scenarios, and early governance make outcomes predictable.
