Designing a cloud infrastructure scaling policy for sole-tenant nodes
Use cases
About
The Node group autoscaler mind map template provides a technical framework for managing sole-tenant node groups in cloud environments, specifically focusing on Google Cloud infrastructure. This 25-node cheat sheet outlines how the autoscaler automatically adjusts group sizes to ensure capacity for virtual machine (VM) instances while optimizing costs. It covers the fundamental logic of 'Overview', 'Modes', and 'Size' constraints. By using this Xmind template, cloud architects can visualize the transition from manual management to automated scaling, ensuring that 'empty nodes' are removed to avoid unnecessary costs and that 'maximum size' limits are strictly maintained to stay within the 100-node sole-tenant boundary.

Planning capacity for BYOL workloads that require physical server affinity
How to use this template
Step 1
Import the template
Open the .xmind file in Xmind to view the structured hierarchy of scaling modes and size constraints.
Step 2
Define scaling parameters
Navigate to the 'Size' branch and replace the placeholder values with your specific 'minimum size' and 'maximum size' requirements.
Step 3
Select your mode
Review the 'Modes' section to determine if your workload requires 'scale out and scale in' or 'only scale out' logic, then highlight your choice.
Frequently asked questions
The template helps cloud engineers visualize the logic behind automated scaling. It ensures that users understand how to avoid paying for 'unused sole-tenant nodes' by configuring the autoscaler to decrease group size when nodes are empty.
According to the 'Modes' branch, this is recommended for monotonically increasing workloads or BYOL (Bring Your Own License) scenarios where licenses must reside on the same physical server.
The 'Size' node specifies that the maximum allowed size for a sole-tenant node group is 100. For larger workloads, the template suggests creating multiple node groups with matching affinity labels.
Yes, this Xmind template is fully editable. You can customize the affinity labels, adjust the min/max integer values, and add specific VM scheduling requirements to fit your cloud architecture.
