Blast radius validation: Large and small Red Hat OpenShift nodes

Summary
This blog post investigates the operational implications of using larger Red Hat OpenShift nodes versus smaller nodes with respect to failure recovery times. It empirically tests the assumption that larger nodes might increase the 'blast radius' during outages. The findings suggest that when resources are proportionally scaled, larger nodes do not significantly extend recovery times. Instead, effective resource scaling and remediation strategies can mitigate concerns about blast radius, maintaining operational efficiency.
