VMware audit before migration: what breaks clean plans

Field report from a multi-site engagement: it's not the inventory that blocks things, it's the gap between declared architecture, actual operations, and rollback capability.

Companies stopping VMware… without having chosen what comes next

What is actually happening in IT leadership since Broadcom is neither a massive migration nor a calm status quo. It's something harder to name: a strategic pause in a decision vacuum.

DRP and HA: what real tests reveal, not slides

Audit findings from critical environments where local high availability masks DRP weaknesses in degraded scenarios.

VMware after Broadcom: what are the consequences for your infrastructure?

A year after the acquisition was finalized, IT directors are measuring the real impact. It's not just a pricing question — it's a re-examination of the five-year architecture trajectory.

Broadcom after VMware: the problem isn't just the price

Field perspective: yes, costs are up. But more importantly, options are gone, governance is strained, and architectural decisions need to be revisited on more realistic foundations.

Building a Proxmox HA cluster: architecture and pitfalls

Enabling high availability on Proxmox is not a checkbox. It's an architecture to design, with critical components that are often misunderstood: Corosync, quorum, fencing, shared storage.

Proxmox POCs: why they pass in the lab and stall in production

Field report on POCs that validate the technology but don't produce an actionable decision for IT leadership in critical environments.

Proxmox vs VMware: what really changes in enterprise environments

Migrating to Proxmox is not a like-for-like replacement. The ecosystem differences, operational maturity, and governance model are real — in both directions. An ideology-free reading.

Proxmox vs Nutanix: operational simplicity against vertical integration

Proxmox and Nutanix represent two fundamentally different HCI philosophies. Not a good and a bad choice — two models whose operational trade-offs deserve an honest reading.

Proxmox vs Hyper-V: the often underestimated choice

Hyper-V is not a legacy hypervisor. For Windows-centric environments, it remains an architecturally coherent choice whose trade-offs are different from what standard comparisons describe.

Proxmox vs XCP-ng: two different visions of open source infrastructure

Proxmox and XCP-ng are both serious open source hypervisors. Their architectural, operational, and ecosystem differences deserve a precise reading for anyone considering either in enterprise production.

PBS vs Veeam: open source backup or established ecosystem?

PBS and Veeam don't compete on the same ground. One is designed for Proxmox, the other for complex heterogeneous environments. Understanding their operational differences avoids surprises in production.

Why more and more enterprises are migrating to Proxmox VE

This isn't a trend. It's the convergence of several real factors — economic, technical, organizational — that make Proxmox credible in enterprise production. With its limits.

Distributed Ceph or traditional SAN: the real trade-off

Choosing between Ceph and a SAN is not a question of modernity. It's a question of operational load, available skills, failure domains, and debugging maturity under incident conditions.
