Post-Broadcom VMware Repatriation: Nutanix AHV vs AWS Outposts vs Bare-Metal OpenStack TCO

Model enterprise hypervisor migration following Broadcom VMware pricing restructuring. Calculate 3-year TCO across Nutanix Acropolis (AHV), AWS Outposts, and bare-metal OpenStack / Proxmox VE.

Executive Sizing Summary: Comprehensive FinOps architectural assessment for migrating a global-scale tco-migration workload (512 vCPUs, 2048 GB RAM, and 180 TB storage) from ON-PREM to ON-PREM. Baseline unoptimized on-demand spend totals $353,747/year. By executing structured commitment arbitrage, storage lifecycle compaction, and network egress decoupling, engineering teams can achieve up to 54% sustainable run-rate savings, reaching financial break-even within 6.8 months.

Executive Analysis: Amortizing CapEx vs Hyperscale Elastic OpEx (AWS)

Evaluating on-premises infrastructure (12 dual-socket servers with 80 TB SAN storage) against AWS demonstrates that hardware acquisition ($204,000 initial CapEx) represents only 35% of total on-premises cost. Operating expenses—such as continuous facility power at 0.13 $/kWh multiplied by a 1.45 PUE cooling factor, colocation leases, and 1.5 dedicated sysadmin FTEs—constitute the remaining 65% of the annual run-rate.

Transitioning to a 3-YEAR-RI strategy on AWS reduces equivalent monthly infrastructure overhead from $29,985 to $26,334, releasing $131,439 in cumulative cash flow over a 36-month investment horizon.

Automated cloud storage lifecycle management balances lower static storage costs against the variable expenses of data access, transition transactions, retrieval fees, and vendor-enforced minimum storage durations. Comparing Amazon S3 Standard ($0.023/GB-mo) against S3 Glacier Deep Archive ($0.00099/GB-mo), the temporal retention crossover threshold required to amortize lifecycle transition fees ($0.05 per 1,000 objects = $0.0512/GB for 1MB objects) is 2.33 months. However, because Glacier Deep Archive enforces a mandatory 180-day (6-month) minimum retention charge, any object deleted or modified before six months is billed for the remainder of the 180-day window, making six months the practical minimum retention period.
