Why thousands of companies are abandoning hyperscalers — and exactly how they’re making the switch
The Cloud Reckoning Is Here
For years, migrating to AWS, Azure, or Google Cloud was the default move for any scaling business. The conventional wisdom was simple: go where the biggest catalog is, absorb the costs, and grow from there.
That logic is breaking down.
In 2026, a growing wave of enterprises — from AI startups to iGaming operators to AdTech platforms — are executing a different kind of cloud migration: away from the hyperscalers, and toward providers like OVHcloud that offer transparent pricing, genuine data sovereignty, and bare metal performance that shared infrastructure simply cannot match.
This guide covers everything you need to know about OVHcloud migration: why businesses are making the move, what the numbers look like, what the technical pathway involves, and how to know if it’s the right decision for your organization.
Part 1: Why Companies Are Initiating OVHcloud Migration in the First Place
The Egress Fee Trap
The single most cited trigger for beginning an OVHcloud migration is the shock of hyperscaler egress fees. Moving data out of AWS, Azure, or GCP is not free — and at scale, it becomes one of the largest line items in an infrastructure budget.
Here’s what those costs look like at 50 TB of monthly egress:
| Provider | Free Allowance | Cost at 50 TB/month |
|---|---|---|
| AWS | 100 GB | ~$4,500 |
| Azure | 100 GB | ~$4,350 |
| Google Cloud | 0–200 GB | ~$4,250 |
| Oracle Cloud | 10 TB | ~$425 |
| DigitalOcean | Up to 11 TB | ~$500 |
| OVHcloud | Unlimited | $0 |
For data-intensive workloads — AI feature stores, real-time bidding platforms, video streaming — these costs don’t just scale linearly. They compound. And because egress fees are intentionally designed to make migration painful, they function as a structural lock-in mechanism, not just a billing line item.
The Hopsworks case makes this concrete. The AI platform company migrated their serverless offering from AWS to OVHcloud and reduced monthly infrastructure spend by 62% — from $8,000 to $3,000 — primarily by eliminating the risk of escalating egress costs as users began processing gigabyte-scale DataFrames. That’s not an edge case. It’s a predictable outcome for any data-heavy business that runs the numbers honestly.
Hidden Costs That Never Appear in the Brochure
Egress is the most visible cost, but it’s far from the only surprise waiting inside hyperscaler bills. Companies approaching OVHcloud migration often discover a cluster of additional charges they had normalized without ever questioning:
Cross-AZ data transfer fees. High-availability architectures spread across multiple availability zones are the recommended pattern for resilient cloud deployments. Yet hyperscalers charge for the inter-zone traffic this generates. Organizations are effectively penalized for following best practices — paying replication costs before serving a single external request.
NAT Gateway processing fees. On AWS, NAT Gateways carry both an hourly charge and a per-GB processing fee that scales with external dependencies: API calls, container image pulls, third-party integrations. For busy microservice architectures, these fees can reach hundreds of dollars per month, creating a perverse disincentive against modern application design.
Control plane charges. AWS EKS and Google GKE both charge approximately $0.10 per hour — roughly $72 per month — just for the Kubernetes control plane, before a single workload node is provisioned.
OVHcloud’s architecture addresses these costs structurally rather than through discounts. Its vRack private network technology spans multiple data centers without metered transfer charges. Its Managed Kubernetes service provides a fully managed, CNCF-certified control plane at no additional cost. These aren’t promotional offers — they reflect a different philosophy about what infrastructure pricing should look like.
Part 2: Data Sovereignty — The Legal Case for OVHcloud Migration
For European businesses and any organization that handles EU citizen data, OVHcloud migration is increasingly less a cost decision and more a legal risk management decision.
The CLOUD Act Problem
The U.S. CLOUD Act of 2018 fundamentally changed the jurisdictional landscape of cloud data. Under this law, the relevant factor is not where data is stored — it’s who controls it. Any cloud provider incorporated in the United States can be compelled by U.S. authorities to produce data stored anywhere in the world, including European data centers.
This creates a direct collision with GDPR, which requires a legal basis for data transfers and treats privacy as a fundamental right of EU residents.
| Legal Dimension | U.S. CLOUD Act | EU GDPR |
|---|---|---|
| Primary Goal | Law enforcement access to digital evidence | Protection of personal data and privacy |
| Jurisdictional Basis | Corporate ownership and control | Physical location and residency |
| Notification Requirement | Often prohibited by gag orders | Mandatory notification of processing |
| Access Mechanism | Subpoena or warrant without foreign review | Mutual Legal Assistance Treaties (MLAT) |
The implications are stark. Complying with a U.S. warrant may breach GDPR. Refusing may trigger U.S. legal liability. The “sovereign cloud” labels offered by U.S. hyperscalers — regional instances, local zones, partner-operated infrastructure — are widely viewed with skepticism among European data protection authorities, because technical separation doesn’t override legal ownership.
OVHcloud is headquartered in France, operates its own infrastructure, and is not subject to U.S. jurisdiction in the way that AWS, Azure, or GCP are. For organizations that have assessed their CLOUD Act exposure as a material risk, this is one of the strongest structural arguments for OVHcloud migration.
The Subsidiary Risk: A Nuance Worth Understanding
A 2024–2025 ruling from the Ontario Court of Justice adds important texture to the sovereignty discussion. The court ordered a Canadian subsidiary of OVHcloud to produce subscriber and account data for IP addresses held on servers in France, the UK, and Australia — outside the traditional MLAT process — despite OVHcloud’s argument that the Canadian entity lacked access to the data and that disclosure would violate French law.
This ruling illustrates that sovereignty is a risk spectrum, not an absolute guarantee. Any corporate structure that touches a foreign jurisdiction creates at least some exposure. For organizations requiring the highest level of impermeability, this case reinforces the importance of working directly with OVHcloud’s European entities and understanding the specific data handling and legal architecture of any deployment.
Part 3: The Technical Case — When Bare Metal Changes Everything
Not every OVHcloud migration is primarily about cost or compliance. For a significant category of workloads, the move is driven by the fundamental limitations of virtualization itself.
What Virtualization Actually Costs You
Every VM running on a hyperscaler sits on top of a hypervisor layer. That layer consumes real hardware resources and introduces performance variability — what’s known as the “noisy neighbor” effect, where the workloads of other tenants on the same physical host affect your application’s performance in ways you cannot predict or control.
For latency-sensitive or compute-intensive workloads, this variability is not just inefficient — it’s disqualifying.
| Workload Type | Cost of Virtualization | Bare Metal Advantage |
|---|---|---|
| AI/ML Training | Hypervisor overhead reduces GPU utilization | Direct hardware access enables 24/7 intensive training |
| High-Performance Computing | Jitter and latency from hypervisor layer | Consistent, predictable CPU and I/O performance |
| Online Gaming | Fluctuating performance degrades user experience | High-frequency CPUs with low-latency networking |
| Big Data Analytics | I/O bottlenecks in shared storage environments | Direct NVMe access with superior throughput |
Trigger points for a bare metal OVHcloud migration typically occur when cloud costs grow disproportionately to performance gains, or when specific hardware configurations — the latest generation of processors, specific memory configurations, NVMe storage density — are required for competitive performance but are unavailable or prohibitively expensive on hyperscaler VM instances.
OVHcloud’s 2026 Bare Metal Line-Up
OVHcloud’s 2026 infrastructure refresh targets the full spectrum of demanding workloads with four distinct server ranges:
Scale 2026 — Built for the most ambitious big data and HPC deployments. These servers use AMD EPYC 9005 series processors, scaling to 384 cores and 768 threads in dual-socket configuration. They support up to 3 TB of DDR5 ECC memory and 92 TB of NVMe storage, with AMD SEV (Secure Encrypted Virtualization) for confidential computing use cases.
Advance 2026 — Designed for blockchain validation nodes, container clusters, and database management. Built on AMD EPYC 4005 processors with up to 16 cores and 32 threads, with a 99.95% SLA.
Game 2026 — Purpose-built for the latency-sensitive gaming and iGaming market. Powered by AMD Ryzen 9000 X3D processors with Level 3 cache memory and high-frequency operation optimized for multiplayer environments.
Rise 2026 — The multipurpose entry point, using AMD Zen 5 microarchitecture for intensive web workloads and light virtualization, at a competitive monthly price point across European and Canadian regions.
All ranges feature private bandwidth options up to 50 Gbit/s and unlimited, guaranteed public bandwidth from 1 to 10 Gbit/s.
Part 4: Migration Pathways — Matching Strategy to Workload
One of the most common misconceptions about OVHcloud migration is that it requires a complete rebuild of existing infrastructure. In practice, organizations have multiple pathways available, each suited to different risk tolerances, timelines, and technical architectures.
Pathway 1: Lift and Shift to Hosted Private Cloud
For organizations with existing VMware or Nutanix environments — whether on-premises or within a hyperscaler — OVHcloud’s Hosted Private Cloud offering enables a direct migration of virtualized workloads without code refactoring.
The VMware acquisition by Broadcom introduced significant pricing and licensing uncertainty that has accelerated this pathway. Many enterprises that were comfortable with a VMware-on-hyperscaler model are now actively seeking alternatives that restore pricing predictability.
| Feature | Managed VMware on OVHcloud | Nutanix NC2 on OVHcloud |
|---|---|---|
| Infrastructure | Single-tenant, fully isolated | Hyperconverged platform (HCI) |
| Management | vSphere, vCenter, NSX | Nutanix Prism Central |
| Migration Tool | Zerto DRP, Veeam | Nutanix Move, HYCU |
| SLA | 99.90% to 99.99% | High availability via node redundancy |
The Nutanix NC2 pathway is particularly relevant for organizations that want to avoid future lock-in. Nutanix supports multiple hypervisors — AHV, ESXi, and Hyper-V — under a single management plane, enabling dual-vendor strategies and genuine workload portability. Critically, OVHcloud does not charge egress fees for moving data back to on-premises or to other providers, meaning the “reversibility” is real rather than theoretical.
Pathway 2: Containerized Migration to Managed Kubernetes
For organizations already running containerized workloads, OVHcloud Managed Kubernetes (MKS) offers a clean migration target that eliminates control plane costs while maintaining feature parity with EKS and GKE.
Key advantages of OVHcloud MKS over hyperscaler Kubernetes services:
- No control plane fee — AWS EKS and GKE both charge ~$72/month for the cluster control plane before any nodes are provisioned. OVHcloud MKS provides this at no extra cost.
- CNCF-certified — Full compliance with the Cloud Native Computing Foundation standard, ensuring portability and ecosystem compatibility.
- Auto-scaling node pools — Equivalent to hyperscaler auto-scaling features, without the proprietary lock-in.
- Cilium and eBPF integration — Advanced traffic control and network policy enforcement with observability that matches or exceeds native hyperscaler offerings.
Pathway 3: Infrastructure as Code Migration
For SaaS companies and large-scale digital platforms that manage infrastructure programmatically, OVHcloud’s Terraform provider enables a systematic, version-controlled migration approach. Supported resources include:
- Public Cloud instances, block storage, and private networks
- Bare Metal server deployment and reinstallation tasks
- Managed Databases (PostgreSQL, MySQL, and others)
- Load balancers, vRack private networks, and IP address management
This pathway allows organizations to define their OVHcloud target architecture in code, test it in parallel with existing hyperscaler deployments, and execute a controlled cutover — maintaining full auditability throughout the migration.
Part 5: Industry-Specific Migration Drivers
AdTech: Eliminating the Bandwidth Tax
Supply Side Platforms and Demand Side Platforms process millions of ad requests per second, each involving low-latency data transfers across multiple systems. On hyperscalers, the combination of egress fees and opaque per-request pricing makes cost modeling nearly impossible — and in an industry where every advertising dollar must be accounted for, financial unpredictability is existential.
OVHcloud migration eliminates egress costs entirely for these operators, replacing a variable and opaque cost structure with predictable fixed-capacity pricing. For high-volume real-time bidding environments, this alone can represent the difference between a viable margin and a structural operating loss.
iGaming: Performance, Availability, and DDoS Resilience
Online gaming and iGaming operators face a specific combination of technical requirements: sudden traffic spikes during major events, zero tolerance for latency, and constant exposure to DDoS attacks targeting both the gaming layer and the payment infrastructure.
OVHcloud’s Game 2026 bare metal servers address these requirements at the hardware level, with high-frequency AMD Ryzen processors and integrated anti-DDoS protection operating across layers 3, 4, and 7. The built-in DDoS mitigation blocks harmful traffic without introducing latency to legitimate game sessions — a critical distinction for operators where player trust depends on consistent performance even during attacks.
Retail and eCommerce: Scaling Without Cloud Sprawl
For retailers, the OVHcloud migration case centers on traffic variability. Handling Black Friday-level demand spikes without pre-provisioning year-round capacity — and without the “cloud sprawl” that accumulates when teams spin up resources on hyperscalers without centralized governance — requires infrastructure that scales predictably and bills transparently.
By migrating to OVHcloud with Kubernetes-based auto-scaling and Terraform-managed infrastructure, eCommerce teams can achieve the elasticity they need during peak periods without paying for idle capacity or discovering unexpected charges after the fact.
Part 7: Sustainability as Infrastructure Strategy
OVHcloud migration isn’t only a financial or legal calculation. In 2026, infrastructure choices are increasingly subject to ESG scrutiny, and data center efficiency has become a measurable component of enterprise sustainability reporting.
OVHcloud’s vertically integrated model — designing and manufacturing its own servers — allows for the implementation of proprietary water-cooling technology that achieves efficiency metrics well beyond industry averages:
| Efficiency Metric | OVHcloud | Industry Average |
|---|---|---|
| PUE (Power Usage Effectiveness) | 1.26 | 1.55 – 1.67 |
| WUE (Water Usage Effectiveness) | 0.37 | 1.8 – 2.5 |
The company’s fifth-generation “Smart Datacenter” architecture, launched in late 2025, uses AI-powered sensors to monitor real-time workloads and environmental conditions. The result: a further 30% reduction in water consumption and up to 50% reduction in cooling electricity use compared to previous generations.
For enterprises reporting on Scope 2 and Scope 3 emissions, these numbers translate directly to a lower carbon footprint from digital operations — and to a provider whose sustainability credentials are structural rather than offset-based.
Part 8: Building Your OVHcloud Migration Roadmap
Step 1: Identify the Anatomy of Failure in Your Current Setup
Before planning the migration, diagnose what’s actually broken. The most common failure modes are:
- Unpredictable billing — Monthly invoices that can’t be accurately modeled in advance
- Performance ceilings — Workloads that consistently hit limits imposed by shared virtualization
- Regulatory non-compliance — Data sovereignty exposure under CLOUD Act jurisdiction
- Vendor lock-in — Proprietary services (managed databases, ML pipelines, messaging queues) with no portable equivalents
Each of these failure modes maps to a different migration pathway and a different sequence of priorities.
Step 2: Choose the Right Migration Pattern
| Your Situation | Recommended Migration Pattern |
|---|---|
| Existing VMware workloads, minimal refactoring budget | Lift and Shift to Managed VMware or NC2 on OVHcloud |
| Containerized applications, Kubernetes-native team | Direct migration to OVHcloud MKS |
| IaC-driven team, willingness to re-architect | Terraform-based re-deployment with phased cutover |
| Mixed workloads requiring hardware isolation | Bare Metal provisioning with OVHcloud Terraform provider |
Step 3: Run the TCO Model Honestly
Any OVHcloud migration decision should include a full Total Cost of Ownership comparison that goes beyond sticker-price compute costs. The model should include:
- Egress costs at current and projected data volumes
- Cross-AZ transfer fees for your current HA architecture
- NAT Gateway or equivalent processing overhead
- Kubernetes control plane charges
- Support tier costs
- Developer time spent navigating complex hyperscaler billing
When organizations run this model for the first time — including all the hidden networking and processing overheads — the case for migration becomes significantly more compelling than a simple compute price comparison would suggest.
Step 4: Execute with Reversibility in Mind
One of the structural advantages of OVHcloud migration — particularly via the Nutanix NC2 pathway — is that reversibility is built in. OVHcloud does not charge for egress when organizations move data back to on-premises or to other providers. This means the migration decision is not permanent, and the infrastructure team retains the ability to rebalance workloads across environments as business needs evolve.
Conclusion:
The businesses executing OVHcloud migration in 2026 are not choosing a budget alternative to AWS or Azure. They are choosing a more mature infrastructure model — one that treats pricing transparency, data sovereignty, hardware performance, and environmental efficiency as first-class requirements rather than optional upgrades.
The hyperscaler model made sense as a starting point: fast access to global infrastructure with no upfront capital commitment. But for organizations that have moved past the early growth phase, the cumulative costs of egress fees, hidden networking charges, proprietary lock-in, and jurisdictional risk represent a structural drag on operational efficiency and financial predictability.
OVHcloud migration offers a path out of that drag — not by sacrificing capability, but by reclaiming the operational freedom that the proprietary ecosystems of global hyperscalers are specifically designed to erode.
The question for most organizations isn’t whether an OVHcloud migration makes sense. It’s whether the switching cost of doing it now is lower than the compounding cost of waiting.
For most businesses that run the numbers honestly, the answer is already clear.
