The right infrastructure for every blockchain workload
Blockchain workloads have fundamentally different infrastructure requirements. Matching each workload to the right environment is the primary lever for cost control and performance.
Hybrid Blockchain Architecture
Most production blockchain deployments use a combination of infrastructure types. Bare metal for validators and data-intensive workloads, public cloud for signer nodes, dev/test environments, and burst capacity. vRack private networking connects all environments securely without touching the public internet, isolating validator keys from public-facing endpoints.
- Bare metal sentry nodes plus cloud signer nodes
- vRack Layer 2 private connectivity across all OVHcloud services
- OVHcloud Connect for private fiber to your data center
- Managed Kubernetes for orchestration layer

INFRASTRUCTURE SELECTION GUIDE
How to evaluate blockchain infrastructure providers
Choose infrastructure for blockchain by evaluating providers at the workload level, not the portfolio level. These are the criteria that matter most — and how OVHcloud addresses each.
| Criteria | What to look for | Why it matters for blockchain | OVHcloud |
| Pricing transparency | No charge for ingress or egress traffic. Flat-rate bandwidth included in server pricing. | Validators and RPC nodes generate substantial outbound traffic. Egress fees make high-throughput chains cost-prohibitive. | Zero egress fees on dedicated servers |
| Hybrid / multi-cloud | Interoperable solutions connecting bare metal, private cloud, and public cloud via private networking. | Production blockchain deployments span multiple infrastructure types. Private L2 connectivity is essential. | vRack + OVHcloud Connect |
| DDoS protection | Always-on mitigation with custom profiles for high-throughput chains. No additional fees. | High-volume blockchain traffic (e.g. Solana's 400 ms block time) can trigger false positives that block valid transactions. | Custom Solana profile included |
| Compliance | SOC 1-2-3, ISO 27001, HIPAA, PCI-DSS certifications. GDPR-compliant data residency options. | Regulatory pressure on blockchain is intensifying. Enterprise and fintech deployments require specific compliance postures. | SOC 2, ISO 27001, HIPAA |
| Confidential computing | Intel SGX / TDX, AMD SEV, Nvidia TEE hardware support for encrypted compute enclaves. | Privacy-preserving blockchain applications require hardware-level data isolation that software encryption alone cannot provide. | AMD SEV on Scale-a3 |
| Openness | Open-source stack with no hypervisor lock-in. Reversible migrations. No proprietary APIs. | Blockchain's core ethos is decentralization. Infrastructure should mirror this with open, portable tooling. | OpenStack, no lock-in |
| Multi-regionality | Data centers in multiple geographies. Ability to place nodes in strategically important markets. | Geographic distribution reduces regulatory risk, improves latency, and supports disaster recovery topologies. | 46 data centers, 4 continents |
| SLA | Minimum 99.99% infrastructure uptime with financial compensation for breach. | Validator downtime results in missed block rewards and potential slashing. Sentry nodes must be continuously available. | 99.99% infrastructure uptime SLA |
KEY INSIGHT
OVHcloud does not host Proof of Work (PoW) blockchain applications or cryptocurrency mining due to their excessive energy consumption. All Proof of Stake (PoS) validators, staking providers, RPC nodes, DeFi applications, and Web3 builders are fully supported.
OVHcloud infrastructure for blockchain
We offer a range of products suited to different blockchain workload types. Most production deployments use a combination.
"Infrastructure is the thing most developers don't want to think about. Our customers range from startups shipping fast to institutions operating in highly regulated markets, like JP Morgan, Robinhood, Visa, Stripe, and Coinbase, and the common thread is they all need reliability and performance without overpaying for it. OVHcloud's bare metal foundation lets us deliver that across regions at a price point that actually makes sense for Web3 builders.”

What is the difference between bare metal and public cloud for blockchain infrastructure?
Bare metal dedicated servers give blockchain operators single-tenant resources, full root access, predictable performance with no shared-tenant interference, and significantly more compute power per dollar for steady-state workloads. Public cloud offers faster provisioning, elastic scaling, and automated orchestration tools like Kubernetes — making it better suited for signer nodes, dev/test environments, and variable-demand workloads. For most production blockchain deployments, a hybrid model is optimal: bare metal for validators and data-intensive nodes, public cloud for burst capacity and orchestration layers.
Does OVHcloud charge egress fees for blockchain workloads?
No. OVHcloud includes bandwidth in dedicated server pricing with no separate egress charges for traffic leaving the network. This is a significant differentiator for blockchain workloads — validators, RPC nodes, and Layer 2 infrastructure generate substantial outbound traffic, and egress fees from other providers can make otherwise viable architectures cost-prohibitive at scale. For Solana nodes consuming approximately 80 TB per month, the savings versus egress-based pricing models are material.
How does OVHcloud handle DDoS protection for high-throughput blockchains like Solana?
We provide always-on anti-DDoS protection included with all dedicated servers at no additional cost. Solana creates a new block every 400 milliseconds, generating traffic volumes that standard DDoS systems may misidentify as malicious flooding. We have developed a custom anti-DDoS mitigation profile for Solana that distinguishes legitimate high-volume blockchain transaction traffic from actual attacks, preventing false positives that block valid transactions.
What cloud infrastructure does a Solana validator node require?
Solana validator nodes require high-core-count CPUs with strong single-thread performance (3.2 GHz+), a minimum of 256 GB RAM for nodes without additional account indexes, NVMe SSD storage, and 10 Gbps+ network uptime. They also require substantial bandwidth — approximately 80 TB per month (40 TB inbound, 40 TB outbound). OVHcloud Scale servers with AMD EPYC processors are well-suited for Solana validators, and we have developed custom anti-DDoS mitigation profiles specifically for Solana's high-volume transaction traffic to prevent legitimate blocks from being flagged as attacks.
What OVHcloud servers are recommended for Ethereum validators?
Advance and Scale dedicated servers from OVHcloud are the most common choices for Proof of Stake (PoS) validator infrastructure. Advance servers (including the Advance-3 with AMD SEV) are widely used for Ethereum validators and confidential computing workloads. Scale servers with AMD EPYC 9355 processors are recommended for Solana and other high-throughput chains. Connect them via vRack for sentry/validator topologies.
Does OVHcloud support Proof of Work mining?
No. OVHcloud does not host Proof of Work (PoW) blockchain applications or cryptocurrency mining operations due to excessive energy consumption. Switching from PoW to PoS reduced Ethereum's power consumption by over 99%. We fully support all Proof of Stake networks, validators, staking infrastructure, RPC nodes, DeFi applications, and Web3 use cases built on energy-efficient consensus mechanisms.
What is the OVHcloud Startup Program for blockchain companies?
