gridscale

  • Panel + API + Terraform provisioning

    Deploy VMs with attached storage in seconds via the control panel or automate with the REST API and common IaC clients (Terraform, Packer). Built for teams that want both click-ops and git-ops without a hyperscaler control-plane learning curve.

  • Managed Kubernetes, databases, and load balancers

    PaaS layers cover managed Kubernetes orchestration plus fully managed databases with audit logs and automatic backups, and managed load balancers for traffic distribution—so app teams avoid running the full stack themselves.

  • S3-compatible object storage and Rocket NVMe storage

    Object storage follows S3-style APIs for backups, archives, and unstructured data, with region choice called out for GDPR-oriented placement. Rocket Storage targets high-IOPS NVMe workloads; not every Hybrid Core location exposes object storage—check the data-center matrix.

  • Per-minute GPU bare-metal for AI/ML

    GPU instances are marketed as dedicated bare-metal performance for AI/ML and data science, with CPU, RAM, and storage included and usage billed by the minute rather than only long-term reserved shapes.

  • Hybrid Core Concierge HCI and white-label cloud

    Fully managed hyperconverged packages combine hardware delivery, installation, remote operations, white-label branding/SAML options, and access to the wider gridscale location ecosystem—aimed at enterprises and hosters building private or partner clouds.

Open Telekom Cloud

  • 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.

Assurance & compliance: gridscale vs Open Telekom Cloud
Assurance & complianceLogo: gridscalegridscaleLogo: Open Telekom CloudOpen Telekom Cloud
Independent security / no-logs audit
Not applicable

IaaS/PaaS provider—not a no-logs VPN product. Request penetration-test or SOC-style reports under NDA if required.

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.

Vendor claimed

SOC 2 Type II (request report); SOC 3 public PDF linked on certifications page. SOC 1 Type II also claimed.

ISAE 3402 SOC 1 Type 2
Vendor claimed

About chronology highlights successful ISAE 3402 SOC 1 Type 2 (incl. January 2025 call-out). Request full report.

Not listed
BSI C5
Vendor claimed

Prominently listed on compliance pages; About chronology pairs C5 with January 2025 certification success. Request current attestation.

Vendor claimed

Vendor claims BSI C5:2020 Type II (ISAE 3000); detailed report typically on request via audit-reports download flow.

GDPR / EU data protection
Vendor claimed

German controller (gridscale GmbH); European location marketing; privacy policy under DS-GVO. Confirm DPA and location selection for your processing.

Vendor claimed

EU operator, EU/CH regions, ISO 27018/27701 claims, DPA language on marketing pages—confirm signed DPA for your entity.

US CLOUD Act exposure (indicative)
Partial

EU entity, no known US parent (OVHcloud France owns group). Customer hosting marketed in EU/CH/AT. Partial because privacy recipient list includes US-group Stripe, Google Analytics/GTM, Microsoft, Meta, LinkedIn for payments/marketing. Not legal advice.

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.

Data processing agreement (B2B)
Vendor claimed

GTC §14.2 requires a separate order-processing contract when gridscale processes personal data for the customer, finalised at latest on contract conclusion. Execute AV/DPA—do not rely on website privacy alone.

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.

EU AI Act
Not applicable

Infrastructure cloud; not an AI system product. GPU capacity may host customer AI workloads under shared-responsibility model.

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.

Trusted Cloud (DE)
Vendor claimed

Compliance page links Trusted Cloud service listing; verify current entry on trusted-cloud.de.

Not listed
TISAX Level 3Not listed
Vendor claimed

Vendor states TISAX Level 3 for Germany and Netherlands regions.

Considerations & known limitations: gridscale vs Open Telekom Cloud
Considerations & known limitationsLogo: gridscalegridscaleLogo: Open Telekom CloudOpen Telekom Cloud
Parent-group integration after OVHcloud acquisition
Medium

100% OVHcloud ownership since 2023 may change roadmap, tooling, support model, or cross-entity data flows over time. Confirm entity, subcontractors, and exit terms for your contract generation.

Not listed
Partner-operated Hybrid Core locations
Medium

Some sites are operated with partners (hosttech, rhöncloud, BAIONITY, windCORES, etc.). Capability matrices differ (for example object storage not everywhere). Map exact location codes to SLA and subprocessor wording.

Not listed
US-group ancillary processors (account/marketing)
Medium

Privacy policy lists Stripe, Google Analytics/GTM, Microsoft Bing Ads, Meta, and LinkedIn. Material for DPIAs even when VM disks stay in EU halls. Ask which tools touch production account identities versus marketing only.

Not listed
Certifications need current attestation packs
Low

BSI C5, ISAE 3402, and ISO claims are vendor-published. Production security reviews should obtain dated reports rather than relying on marketing badges alone.

Not listed
Narrower global footprint than hyperscalers
Low

Location set is European-weighted. Unsuitable as a drop-in for multi-continent latency or hyperscaler-only services (global CDN marketplaces, specialized managed services).

Not listed
Historical Huawei technology partnershipNot listed
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.

Service catalog differs by regionNot listed
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.

Limited public subprocessor tableNot listed
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.

Smaller global ecosystem than AWS/Azure/GCPNot listed
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.

Brand transition OTC → T Cloud PublicNot listed
Low

Documentation, console URLs, and community still mix Open Telekom Cloud and T Cloud Public names. Factor rebrand into runbooks and vendor risk registers.

Fit

gridscale

Best fit when

  • DACH mid-market teams wanting German contracting plus managed PaaS (Kubernetes, databases, load balancers)
  • MSPs and hosters needing white-label branding, multi-tenant accounts, and optional Hybrid Core hardware
  • Workloads that must pick DE/NL/CH/AT regions with Tier 3 marketing claims and green-energy positioning
  • AI/ML or data-science jobs that need GPU bare-metal with per-minute metering
  • Buyers who value panel + API/Terraform over hyperscaler IAM sprawl

Poor fit when

  • Global multi-region applications that need hyperscaler edge, marketplace services, or non-European regions
  • Teams optimising only for lowest bare VM or dedicated-server unit cost (evaluate Hetzner first)
  • Buyers requiring public SOC 2 Type II specifically rather than ISAE 3402 SOC 1 Type 2 / BSI C5 packs
  • Organisations that forbid any US-group ancillary processors (Stripe/Google marketing tools appear in the privacy recipient list)

Consider instead when

  • When: You need the broader European hyperscale portfolio and more regions under one group brand

    Consider: OVHcloud

    OVHcloud is the parent group; gridscale stays the HCI/panel-focused product line

  • When: Cost-sensitive VMs or dedicated servers dominate and you do not need Hybrid Core white-label

    Consider: Hetzner

    Hetzner typically wins raw price/performance for simple compute

  • When: France-centric developer cloud with different location and product skew

    Consider: Scaleway

    Compare ARM options and FR footprint versus gridscale DACH Hybrid Core

  • When: Swiss-rooted EU cloud positioning is the primary evaluation criterion

    Consider: Exoscale

    Still compare DE/CH site maps and managed service depth side by side

  • When: You need worldwide regions, marketplace depth, or US-public-sector cloud programmes

    Consider: Amazon Web Services (AWS) or Microsoft Azure

    Trade EU-entity simplicity for hyperscaler breadth and US ownership path

Open Telekom Cloud

Best fit when

  • German public sector and regulated buyers needing Telekom-group operator plus BSI C5 / ISO package
  • Enterprises pinning workloads to DE, NL, or Swiss twin-core regions under GDPR (and Swiss DSG where relevant)
  • Teams wanting OpenStack-based IaaS with ECS, object/block storage, VPC, and Kubernetes (CCE) without US hyperscaler residency defaults
  • AI/ML projects that require GPU capacity and ModelArts-class tooling with European data residency messaging
  • Hybrid architectures using Direct Connect / VPN into Telekom data centers with 24/7 European support expectations

Poor fit when

  • Workloads that require dozens of global regions or deep proprietary hyperscaler PaaS catalogs
  • Buyers seeking a free self-hosted OpenStack distribution rather than a commercial public cloud
  • Teams that need every service in every region—several AI, bare-metal, and data services are DE-only or limited
  • Organisations that reject any non-European technology supply chain without further review (historical Huawei partnership)

Consider instead when

  • 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.

Open questions for due diligence

gridscale

  • Will gridscale execute your template AV/DPA and attach a location-specific subprocessor list for the regions you enable?
  • What is the current scope and report date for BSI C5 and ISAE 3402 SOC 1 Type 2 covering the services you will buy?
  • Which privacy-policy third parties process production account/identity data versus website marketing only?
  • How are OVHcloud group affiliates involved in support, billing, or platform operations for gridscale customers post-acquisition?
  • For Hybrid Core partner sites, who is the data-center operator of record and what audit rights apply?

Open Telekom Cloud

  • Will T-Systems provide the current full subprocessor/subcontractor list and signed DPA annex for our legal entity and region?
  • What is the residual Huawei (or other non-EU) component inventory for the regions we will use, and is it acceptable under our procurement policy?
  • Which services in our target architecture are available in DE vs NL vs Swiss regions with which SLAs?
  • Can we obtain current C5 Type II and SOC 2 reports (not only marketing claims and SOC 3 summary) under NDA?
  • For AI workloads, which ModelArts/GPU SKUs and data paths apply, and how do they map to our EU AI Act role?
