The advisory entry point. Use when starting a new data-portal project and the underlying architecture has not yet been decided.PlanningNo warnings★ 2.4K↓ —
- virtualization-operationscbrock84/headcountRuns the hypervisor layer beneath the servers — host capacity and consolidation ratios, VM sprawl, snapshot discipline, resilience and live migration, and licensing that counts cores rather than instances. Use this to size or expand a cluster, work out why VMs are slow when the hosts look idle, clean up sprawl, set snapshot and template policy, or decide what stays virtualized and what moves to cloud.OtherNo warnings★ 2.6K↓ —
