THE ARCHITECT’S VERDICT // COMPARATIVE SUMMARY

Best for Legacy Apps

VMware vSphere (VCF)

Maintain high-density bare-metal performance and deep 3rd party tool integration for monolithic applications. Utilize the monolithic VMkernel for high-density, bare-metal isolation.

Best for Hybrid Cloud

Nutanix NCI / NC2

Seamlessly extend on-prem license mobility to AWS and Azure without refactoring the networking fabric. Unified platform for VMs, containers, and unified storage silos with turnkey Integrated AI.

Best for Sovereign TCO

Proxmox / OpenShift

Eliminate proprietary licensing lock-in and adopt open-source hypervisor physics for air-gapped or localized clusters. Leverage SDN to decouple network services and enable overlapping IP ranges.

UNBIASED ARCHITECTURAL AUDITS

Don’t renew Broadcom without a strategy. Our engineering team provides vendor-neutral technical audits to ensure your 2026 infrastructure stack aligns with your performance and fiscal requirements.
