OpenStack public cloud with Elastic Cloud Server and GPUs
Self-service IaaS on OpenStack: Elastic Cloud Server flavors from general-purpose to GPU shapes for AI/ML and graphics, plus Dedicated Host and Bare Metal where the region supports them. Provision via console, API, or automation; Auto Scaling for metric-driven capacity. Suited to production VMs and hybrid patterns that need European operator control rather than a thin VPS plan.
Multi-AZ object, block, and file storage in EU regions
Object Storage Service provides S3-compatible multi-AZ object storage; Elastic Volume Service attaches block disks with snapshots; Scalable File Service offers NFS shared filesystems. Cloud Backup and Recovery and related services back up VMs and volumes into platform object storage. Pin workloads to DE, NL, or Swiss regions according to residency policy.
VPC networking, Direct Connect, and security services
Virtual Private Cloud isolation, Elastic Load Balancer, VPN, NAT, Enterprise Router, and Direct Connect for high-bandwidth hybrid links. Security stack includes Anti-DDoS, WAF, Cloud Firewall, Host Security Service, and Key Management Service with bring-your-own-key options—useful for regulated network architectures without leaving Telekom-operated regions.
Cloud Container Engine and managed data services
Cloud Container Engine runs Kubernetes-managed clusters and images; companion services cover container instances and registries. Relational Database Service supports MySQL, PostgreSQL, and Microsoft SQL with HA and backup patterns; document, cache (Redis-class), MapReduce, and search services extend the data plane. Service availability differs between DE and NL—check the regional matrix before design freezes.
ModelArts and sovereign AI positioning
ModelArts provides an end-to-end AI development path (data prep, training, deployment) on European infrastructure, with GPU-backed instances for training and inference. Aimed at teams that want model and training-data residency under the same European operator as their IaaS—confirm which AI services exist in your chosen region (several AI offerings are DE-focused).
Twin-core European data centers (DE, NL, CH)
Published regions: twin-core Germany (Biere/Magdeburg), Netherlands (Amsterdam area), and Switzerland (Bern/Zollikofen) for Swiss data residency. Vendor claims geo-redundant twin-core design, high availability targets, and renewable-powered German facilities. Not a global multi-continent footprint—by design for European sovereignty shortlists.
KVM Cloud Servers with dedicated resources
Cloud Server is a KVM virtual machine with dedicated CPU, RAM, and SAN-backed storage, N+1 style redundancy messaging, and guaranteed 1 Gbps bandwidth class. Scale vertically (add CPU/RAM/disk) or horizontally by composing multi-tier stacks. Unmanaged or fully managed by Seeweb engineers—fit for production web, DB, and agency workloads that need predictable isolation rather than noisy shared hosts.
GPU cloud for AI/ML (NVIDIA + AMD)
Cloud Server GPU instances target training, inference, and HPC-style jobs with NVIDIA cards (H100, H200, A100, L40S, RTX A6000, L4 and related) and AMD options including MI300X. Ready-to-use drivers, Terraform support, hourly usage billing, and Spot Instances with a short preemption notice suit bursty or interruptible jobs. Data stays on European sites per vendor GDPR messaging—confirm region per SKU at order time.
Managed Kubernetes Service (SKS)
SKS is Kubernetes-as-a-Service with a HA control plane, worker sizing you design with Seeweb, CSI storage (Vast Data driver on the product page), optional S3-compatible object storage, load balancing, and GPU workers (including MI300X and NVIDIA H-class cards). Aimed at teams that want orchestration without running etcd themselves; Proactive Support tiers add predictive monitoring for production clusters.
VPC, Foundation Server, and hybrid DC footprint
Virtual Private Cloud builds private infrastructures on VMware or Proxmox; Foundation Server targets dedicated bare-metal-style capacity for business-critical virtualization. Combine with housing/colocation in Milan and Frosinone plus European partner sites for DR. Useful when you need private networking and dedicated hosts under the same Italian operator rather than public multi-tenant only.
ACN-qualified IaaS and CISPE EU residency claims
Seeweb publishes ACN CSP qualification (QI2 infrastructure; QC2 for Foundation Server Pro, VPC, Shared CPU/High Memory cloud, and AI/supercomputing infrastructures) for Italian public administration procurement. CISPE Code of Conduct registration is used to assert customer data stored exclusively in European territories. Pair these claims with your own DPIA—they are procurement signals, not a substitute for a signed DPA.
| Assurance & compliance | Open Telekom Cloud | Seeweb |
|---|---|---|
| Independent security / no-logs audit | Not applicable IaaS platform—not a no-logs consumer VPN. Independent assurance is via ISO/SOC/C5-style audits rather than a no-logs report. | Not applicable IaaS/data-center provider—not a consumer no-logs VPN. Assurance is via ISO/ISMS and sector qualifications rather than a no-logs report. |
| ISO 27001 | Vendor claimed Vendor certifications page links ISO/IEC 27001 umbrella certificate PDF for download; re-verify serial/date in procurement. | Vendor claimed Vendor certifications page: ISO/IEC 27001:2022, AXE REGISTER cert IT18-27702D, valid until 28 Nov 2027; locations Milan & Frosinone. Re-verify serial in procurement. |
| ISO/IEC 27017 (cloud security) | Vendor claimed Claimed with downloadable attestation PDF on certifications page. | Vendor claimed Appendix to ISO 27001 certificate on certifications page; same validity window stated. |
| ISO/IEC 27018 (cloud PII) | Vendor claimed Claimed with downloadable attestation PDF on certifications page. | Vendor claimed Appendix to ISO 27001 certificate on certifications page; same validity window stated. |
| SOC 2 / SOC 3 | Vendor claimed SOC 2 Type II (request report); SOC 3 public PDF linked on certifications page. SOC 1 Type II also claimed. | Not found No SOC 2/3 report advertised on the official certifications page at research time. |
| BSI C5 Type II | Vendor claimed Vendor claims BSI C5:2020 Type II (ISAE 3000); detailed report typically on request via audit-reports download flow. | Not listed |
| TISAX Level 3 | Vendor claimed Vendor states TISAX Level 3 for Germany and Netherlands regions. | Not listed |
| GDPR / EU data protection | Vendor claimed EU operator, EU/CH regions, ISO 27018/27701 claims, DPA language on marketing pages—confirm signed DPA for your entity. | Vendor claimed Italian controller/processor entity, European hosting messaging, privacy policy, ISO 27018 claim, CISPE; confirm DPA for your processing roles. |
| US CLOUD Act exposure (indicative) | Partial German Telekom/T-Systems operator, no known US parent of the cloud business, primary hosting on Telekom EU/CH data centers (not AWS/GCP/Azure). Not a legal clearance of zero extraterritorial risk. Historical Huawei tech partnership is separate supply-chain diligence. Not legal advice. | Partial Italian Seeweb S.r.l., Italian DHH parent, no known US parent; primary hosting on European DCs (not AWS/GCP/Azure). Third-party Swiss/BG facilities and global transit carriers exist. Indicative only—not legal advice. |
| Data processing agreement (B2B) | Vendor claimed Vendor GDPR pages state DPA, TOMs, and audit reports available for B2B; obtain current signed pack—not fully self-serve public template verified here. | Vendor claimed Art. 28 DPA language used for Seeweb-operated services (e.g. published for Regolo); request current signed DPA + TOMs + subprocessors for core cloud/IaaS contracts. |
| EU AI Act | Partial Platform offers AI services (ModelArts) that may fall under customer AI Act obligations; OTC itself is infrastructure—not an automated high-risk AI system assessment by EuropeanStack. | Partial Infrastructure/GPU provider and Rethic.AI partnership messaging; AI Act duties mainly fall on customer AI systems. Not a full provider high-risk AI assessment by EuropeanStack. |
| CISPE Data Protection Code of Conduct | Not listed | Vendor claimed Vendor states CISPE registry presence and European data storage under the Code (since 31 May 2017 on certifications page). |
| ACN Qualified CSP (QI2/QC2) | Not listed | Vendor claimed IaaS qualification for Italian PA; QI2 infrastructure and QC2 for listed products including AI/supercomputing infrastructures (19 Jan 2023 on certifications page). |
| CSA STAR Level 1 | Not listed | Vendor claimed Stated for Virtual Private Cloud and Foundation Server PRO (6 July 2022 on certifications page). |
| Considerations & known limitations | Open Telekom Cloud | Seeweb |
|---|---|---|
| Historical Huawei technology partnership | Medium Platform launched with Huawei hardware/software partnership; residual stack components may still matter for sensitive public-sector RFPs. T-Systems states independent operation. Review supply-chain docs under NDA. | Not listed |
| Service catalog differs by region | Medium Several services (e.g. ModelArts, bare metal, some database/analytics SKUs) are unavailable in NL or limited to DE. Design against the live regional matrix, not the full marketing list. | Not listed |
| Limited public subprocessor table | Low Unlike some SaaS vendors, a complete public subprocessor inventory was not found on marketing pages. Request DPA annex and subcontractor list before high-assurance processing. | Medium Facility partners and network carriers are described on DC pages, but a consolidated customer-content subprocessor list was not found as one public document. Request annex under NDA for regulated workloads. |
| Smaller global ecosystem than AWS/Azure/GCP | Low Expect fewer regions, fewer proprietary PaaS services, and a smaller marketplace than US hyperscalers. Migration tools and partner ecosystem exist but differ in depth. | Not listed |
| Brand transition OTC → T Cloud Public | Low Documentation, console URLs, and community still mix Open Telekom Cloud and T Cloud Public names. Factor rebrand into runbooks and vendor risk registers. | Not listed |
| Smaller global footprint than hyperscalers | Not listed | Medium Region set is European (IT/CH/BG) with a mid-size operator catalog. Multi-continent apps or niche managed PaaS may force multi-cloud or a larger EU peer. |
| Certifications are vendor-published | Not listed | Low ISO and ACN claims include certificate numbers and dates on seeweb.it, but EuropeanStack did not re-download every registry PDF. Re-verify serials and scope statements in formal assurance reviews. |
| GPU Spot Instances can be interrupted | Not listed | Low Vendor documents ~2-minute notice before Spot termination when On-Demand needs capacity. Architect batch/checkpointing; do not run sole critical control planes only on Spot. |
| Some sites use third-party data centers | Not listed | Low Lugano, Zurich, and Sofia are presented via partner facilities (Swisscom, Global Data Centers Switzerland AG, Evolink). Italy-only residency must be contracted explicitly if required. |
When: You need extensive bare-metal catalogs and a very large multi-country EU footprint
Consider: OVHcloud
Different operator (France) and product packaging; compare bare-metal and region maps.
When: You prefer developer-centric European cloud packaging outside the Telekom stack
Consider: Scaleway or Exoscale
Scaleway for FR/NL-oriented developer UX; Exoscale for Swiss multi-zone IaaS + managed K8s.
When: You need global regions, marketplace depth, or proprietary PaaS only hyperscalers provide
Consider: AWS, Microsoft Azure, or Google Cloud Platform
Accept US-parent CLOUD Act exposure and multi-region complexity in exchange for breadth.
When: You want German-market hosting adjacency with a different commercial/product mix
Consider: IONOS
Often compared for German buyers; validate IaaS depth vs OTC enterprise cloud features.
When: You need a large multi-country European cloud with denser product catalog and strong self-service DX
Consider: OVHcloud or Scaleway
Broader regions and developer tooling; less Italian ACN-specific packaging than Seeweb.
When: You want another Italian sovereign cloud with mass-market public-cloud SKUs
Consider: Aruba Cloud
Closest national peer; compare GPU/K8s maturity and PA qualification details side by side.
When: You mainly need simple self-service VMs/storage at aggressive commercial terms without Italian PA focus
Consider: Hetzner
Strong for general-purpose EU VMs; different compliance and support model.
When: You require global enterprise PaaS and marketplace ecosystems
Consider: AWS or Microsoft Azure
Accept US-group cloud and CLOUD Act exposure tradeoffs for breadth.
