GKE compute cost comparisons in small clusters
Alex Moss
In this article, you will compare the compute costs for four different strategies on GKE:
- Righ-sizing workloads.
- Autopilot.
- Node auto-provisioning.
- Spot instances with Node auto-provisioning or Autopilot.
Kubernetes Authentication: comparing solutions
Marc Boorshtein
