The “Day 2” Reality of Migrating VMware to Nutanix: What the Migration Tools Don’t Tell You
Everyone loves the “green lights” on a migration dashboard. I’ve sat in plenty of steering committee meetings where the project lead flashes a slide showing 500 VMs successfully moved from ESXi to AHV using Nutanix Move. There is applause, the project is marked “Complete,” and the consultants leave. But for the Solution Engineers and Cloud…

Translating the Stack: A Field Guide to Migrating NSX-T Security to Nutanix Flow
The most dangerous part of a hypervisor migration isn’t moving the data—it’s moving the logic. In the VMware ecosystem, NSX-T is often a sprawling, network-centric overlay. In the Nutanix ecosystem, Flow Microsegmentation is a workload-centric attribute. If you attempt a 1:1 “lift and shift” of your firewall rules without understanding the underlying philosophy shift, you…

Governing The Shadow Architecture: A 2025 Guide to Enterprise LCNC
Around 2018, I watched a Fortune 500 financial firm lose six months of engineering velocity because a marketing sub-team built a “simple” customer intake portal using a No-Code tool that didn’t support their VPC security requirements. By the time the Security Architects found it, 50,000 PII records were sitting in an unencrypted third-party database. This…

Building a Practical Disaster Recovery Plan for Your First Cloud Project
I still remember the first “cloud” Disaster Recovery (DR) plan I reviewed back in 2012. The team assumed that because their app was running on AWS, it was magically invincible. “It’s in the cloud,” they said. “Amazon handles that.” Six months later, us-east-1 had a wobble, and that team spent 14 hours manually rebuilding databases…

Think Like an Architect: The Field Guide to Cloud Egress and Data Gravity
When you’re designing for Day 2 operations, you quickly realize that data isn’t just heavy—it’s expensive to move. I’ve seen countless “cloud-native” projects hit a wall during the scaling phase because the architect assumed egress was a flat overhead. It isn’t. It’s a variable tax that scales with your success. To build like an engineer,…
Slicing the Veeam “API Tax”: A 2025 Architect’s Guide to Immutable Object Storage
When you’re designing a Veeam-to-Cloud architecture, the per-GB storage price is the “marketing number.” But for those of us building for Day 2 operations, the number that actually matters is the IOPS-to-Object ratio. I’ve seen too many architects treat S3 like a tape drive, only to be blindsided by a monthly bill where 40% of…

“Gap of Grief”: Why Your Terraform Code Fails on Day 1
The “Gap of Grief”: While cloud providers speed ahead with new features, infrastructure-as-code tools often carry a heavy load of legacy support, creating a measurable lag. I’ve been designing cloud infrastructures for over 15 years, and the story is always the same. You see a flashy announcement at re:Invent or Ignite—maybe it’s a new high-performance…
The Terraform “Wrapper Tax”: Why I Stopped Abstracting Multi-Cloud Modules
The dream of “Write Once, Run Anywhere” Infrastructure as Code has mutated into a nightmare of technical debt. It’s time to embrace verbose, native code. Around 2018, many of us in the DevOps space shared a collective dream. We believed that with enough clever Terraform coding, we could abstract away the underlying cloud provider completely….
Hybrid vs Multi‑Cloud in 2025: What Systems Engineers Actually Need to Know
By 2025, the boardroom debate about “moving to the cloud” is largely over. It has been replaced by the far more complex engineering reality of managing the resulting sprawl. The discussion around Hybrid vs Multi-Cloud in 2025 has gained traction as businesses seek optimal solutions for their infrastructure needs. Understanding Hybrid vs Multi-Cloud in 2025…
Beyond the Migration: Best Practices for Running Omnissa Horizon 8 on Nutanix AHV
In our previous guide, we covered the milestone event of Omnissa (formerly VMware EUC) officially supporting Horizon 8 on Nutanix AHV. We discussed the “why” and the high-level “how” of getting your workloads migrated off ESXi and onto the native Nutanix hypervisor. Now, the dust has settled. Your connection servers are talking to Prism Element,…
Is Azure SQL Native Backup Enough? Why Smart Architects Add Rubrik
When you migrate to Azure SQL Managed Instance (MI) or Azure SQL Database, one of the biggest sighs of relief is handing backup management over to Microsoft. Out of the box, Azure provides excellent operational recovery capabilities. You get automatic full, differential, and transaction log backups. You get Point-in-Time Restore (PITR). You get geo-redundancy to…
The Engineer’s Guide to SQL Migration: Stopping the Analysis Paralysis
The hardest part of moving SQL Server to Azure isn’t the technical migration; it’s the decision on where to land. A glance at the Microsoft documentation reveals a confusing alphabet soup of options: SQL on Azure VM (IaaS), Azure SQL Managed Instance (PaaS), and Azure SQL Database (PaaS), not to mention elastic pools and hyperscale…
Nutanix’s Sovereign Cloud Push: What It Means for Hybrid & Multi-Cloud Architects
The era of the “borderless cloud” is hitting a geopolitical wall. For the past decade, the primary directive for cloud architects was speed and scalability. We deployed to regions based on latency to the user, largely ignoring jurisdictional lines. Today, regulatory frameworks like GDPR in Europe, the upcoming Digital Operational Resilience Act (DORA), and increasing…
Ransomware‑Ready Backup Strategy for 2025: What Every Engineer Must Know
In 2020, the advice was “have good backups.” In 2025, that advice is dangerously incomplete. Today, backup infrastructure is not the remediation; it is the primary target. Modern ransomware cartels know that if they encrypt your production data, you will restore. But if they delete your backups first, you will pay. Attackers now spend weeks…
The “Lift and Shift” Cost Trap: A Sysadmin’s Guide to FinOps and Avoiding Cloud Sticker Shock
Introduction: The “Lift and Shift” Trap You’ve successfully migrated your first workload. The terraform applied cleanly, the latency looks good, and the boss is happy. Then, 30 days later, the first bill arrives. It’s 40% higher than your estimate. Welcome to the “Lift and Shift” trap. For traditional sysadmins, “capacity” was a sunk cost. If…
From Sysadmin to Cloud Engineer in 2025: The Definitive Skills Roadmap
Introduction: The Server Room is Evolving, Not Dying If you are a traditional systems administrator, you’ve likely felt the shift.

Nutanix vs VMware vs Hyper‑V: How to Build a Fair Comparison as a Solutions Engineer
The virtualization market has experienced a seismic shift. For fifteen years, the answer to “Which hypervisor should we use?” was almost automatically “VMware vSphere.” It was the default, the gold standard, the safe bet. Then came Broadcom. Today, Solutions Engineers (SEs) are facing an unprecedented wave of customers demanding alternatives. The questions have shifted from…
Sizing On-Prem AI: An Architect’s Look at Nutanix’s New GPT-in-a-Box Workflow
The “T-Shirt Sizing” Era of AI is Over For the last year, sizing AI workloads on-premises has felt a bit like the Wild West. We’ve been relying on rough spreadsheets, “t-shirt sizes” (Small, Medium, Large), and a fair amount of guesswork regarding inference overhead. That changed today. Nutanix released Sizer 6.0.94 (Release Date: 16-Dec-2025), and…
Breaking the HCI Silo: Nutanix Integration with Dell PowerFlex & Pure Storage
For over a decade, Nutanix’s mantra was “HCI or Death.” The philosophy was simple: storage and compute must live together in the same box to guarantee performance and simplicity. However, the post-Broadcom VMware landscape has forced a market evolution. Enterprises want the freedom to keep their expensive Storage Area Networks (SANs) while migrating away from…
Hyper-V vs Nutanix AHV: Sizing Compute for Your First Customer PoC (A Decision Framework)
Introduction: The High Stakes of PoC Sizing For a Solution Engineer (SE), the first customer Proof of Concept (PoC) is critical. It’s where marketing slides meet operational reality. A successful PoC accelerates sales cycles and builds immense trust. A failed PoC—often due to poor performance—can set a relationship back months or end it entirely. The…
Nutanix AOS vs VMware vSphere: How to Demo Both Without Bias
Introduction: The SE’s Dilemma In the on-premises and hybrid cloud infrastructure market, there are two undisputed gravitational forces: VMware vSphere and Nutanix AOS.

A biased…
VMware Cloud Foundation vs. vSphere + NSX: A Deep Dive on Positioning for SEs
The Modern Infrastructure Dilemma As organizations strive for cloud-like agility on-premises, they inevitably encounter a fork in the road. Do they continue to build and manage their infrastructure stack component by component, or do they adopt an integrated platform approach? For Solution Engineers (SEs), articulating the value and trade-offs of these two paths is a…
Azure Landing Zone vs. AWS Control Tower: The Architect’s Deep Dive
Same Destination, Different Vehicles By now, the concept of a “Landing Zone” is well understood in the enterprise. It is the pre-configured, secure, and scalable foundation upon which workloads are deployed. It’s the antidote to the “wild west” of unmanaged cloud accounts and subscriptions. For Solution Engineers and Architects working in multi-cloud environments, simply knowing…
AWS Organizations and Control Tower: What SEs Need to Explain to Customers
The Evolving Role of the SE in a Governed Cloud World The days of simply spinning up a single AWS account for a customer are long gone.
