Public traffic reaches them only through Cloudflare's application security, and administrators connect through Cloudflare Zero Trust instead of a VPN or open SSH ports. ## The problem Some workloads need hardware that is expensive in the big clouds or not available in the region they must run in: GPUs for inference or rendering, servers with many cores for simulation or builds. Running that hardware yourself means a public IP address, open ports for users and for administrators, and a VPN to maintain. ## How the pieces fit 1. **The servers** run in the Noraina data centre you choose, with the configuration your workload needs. We operate the platform, network and firewall around them; you keep control of what runs inside. 2. **Public access** goes through Cloudflare. A Cloudflare Tunnel connects the server out to Cloudflare, so nothing listens on the internet. The WAF, DDoS protection, bot management and API protection filter every request first. 3. **Administrative access** goes through Cloudflare Access. SSH, RDP and management consoles are published as applications with policies based on identity and device posture, and every session is logged. 4. **Logs** from both paths are kept with Cloudflare Logpush in storage you control or in your SIEM. Our network peers locally with Cloudflare, so the path between the servers and the edge is short. ## What you get - The hardware your workload needs, in the European data centre and country you need. - No open inbound ports for users or administrators. - No VPN: access per application, verified on every connection and removed in one place. - A complete log of who accessed what, as evidence for access control and logging requirements. ## Cost Server configurations are quoted per workload, and Cloudflare depends on your plan. [Tell us what you need to run](https://www.noraina.cloud/contact/) and we send a proposal. ## Frequently asked questions ### Can I run GPU servers in a European data centre with Noraina? Yes. We place servers with the hardware your workload needs, such as GPUs or high core counts, in one of our data centres in London, Dublin, Paris or Barcelona, and run the platform around them. Tell us the workload and the site you need, and we propose a configuration and a price. ### How do we expose a service on our server without opening it to the internet? A Cloudflare Tunnel runs on the server and connects out to Cloudflare, so there are no open inbound ports. Users reach the service through Cloudflare, where the WAF, DDoS protection and bot management filter every request before it reaches the server. ### How do administrators connect to the servers without a VPN? Through Cloudflare Access. Each SSH, RDP or web console is an application with its own policy that checks the administrator's identity and device before every connection, and every session is logged. Access is removed in one place when someone leaves. ## Compliance Our services support these controls and produce evidence for them. Certification depends on your whole management system and is granted by an accredited auditor, not by a supplier. - **ISO 27001**: 8.15, 8.16, 8.20, 8.26, 5.15, 8.5, 8.12, 8.22, 8.23 (https://www.noraina.cloud/compliance/iso-27001/) - **ENS**: op.exp.8, op.mon.3, mp.s.2, mp.s.4, op.mon.1, op.acc.2, op.acc.4, op.acc.6, mp.s.3, mp.com.1 (https://www.noraina.cloud/compliance/ens/) - **PCI DSS**: 10.2.1, 10.5.1, 4.2.1, 6.4.2, 6.4.3, 11.6.1, 1.3.1, 7.2.1, 8.4.2 (https://www.noraina.cloud/compliance/pci-dss/) - **NIS2**: 21.2.b, 21.2.e, 21.2.i, 21.2.j (https://www.noraina.cloud/compliance/nis2/) - **DORA**: art.10, art.9 (https://www.noraina.cloud/compliance/dora/) - **GDPR**: art.33, 32.1.b (https://www.noraina.cloud/compliance/gdpr/) Last updated: 2026-10-08
