Cluster (and Virtual Node Group) Orientation

Cloud service provider relevance: GKE.

While Ocean is designed to optimize for both availability and cost, you may want to have control over which optimizations are given priority. For example, you might want to run cheaper nodes for clusters on a less stable platform rather than running expensive nodes on a more stable platform.

You can control the approach that Ocean takes by configuring the cluster (and vng) orientation.

Ocean Orientations​

Ocean (GKE) supports the following orientations:

  • Balanced:(default orientation) Ocean optimizes for continuity of operations and cost-effective infrastructure. Spot recommends using this orientation, which provides the optimal balance between cost savings and availability.
  • Cost: Ocean gives greater weight to cheap instances in the decision process.
  • Availability: Ocean gives greater weight to stability in the decision process.
note

Ocean will fall back to a regular instance if the required instance type or the lowest price for an instance type is unavailable.

Set Up Cluster or VNG Orientation for GKE in the Spot API​

To define the cluster scaling orientation for your Ocean cluster, you can use the Create Cluster or Update Cluster APIs.

Look for the following attributes:

cluster.strategy.scaingOrientation

For virtual node groups: Create Virtual Node Group and Update Virtual Node Group.

Look for the following attributes:

launchSpec.strategy.scalingOrientation
