Exoscale

  • Multi-zone European KVM compute

    Launch KVM instances in published zones across Switzerland, Germany, Austria, Bulgaria, and Croatia. Families cover standard, CPU-, memory-, and storage-optimized profiles plus NVIDIA GPU shapes; anti-affinity groups, instance pools, snapshots, custom templates, security groups, and live migration support production patterns. Billed per second with powered-off storage semantics as documented.

  • SKS managed Kubernetes (CNCF certified)

    Scalable Kubernetes Service deploys a managed control plane quickly (vendor claims under about a minute to two minutes). Starter is free without SLA; Pro adds HA control plane, etcd backups, and SLA language. Node pools use Exoscale instance types including GPUs; NLB, CSI storage, autoscaling/Karpenter (Pro), and vanilla CNCF-conformance positioning keep the stack portable.

  • Managed DBaaS on Exoscale compute (Aiven orchestration)

    Managed PostgreSQL, MySQL, Kafka, OpenSearch, Valkey, Grafana, and related engines run as DBaaS with automated backups, plan scaling, and high-availability options. Orchestration subprocessor is Aiven Oy (Finland); database instances run on Exoscale infrastructure in the zone you choose—confirm geo-replication and plan limits in docs before multi-region designs.

  • S3-compatible object storage and block volumes

    Simple Object Storage provides S3-compatible APIs for backups, media, and app assets integrated with Exoscale IAM and zones. Block storage attaches persistent NVMe-class volumes to instances and Kubernetes via CSI for stateful workloads without tying data solely to local disks.

  • IAM, private networks, and automation APIs

    Fine-grained IAM on API keys, private networks, and network load balancers support multi-tier designs. Portal, CLI, API, and Terraform-friendly workflows match common European DevOps practice without requiring a proprietary control language.

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: Exoscale vs Open Telekom Cloud
Assurance & complianceLogo: ExoscaleExoscaleLogo: Open Telekom CloudOpen Telekom Cloud
Independent security / control audit
Partial

Vendor states regular independent audits and publishes multi-framework certs via Compliance Center; not a VPN-style no-logs audit. Download current reports under account/NDA for verification.

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.

ISO 27001
Vendor claimed

Vendor asserts ISO/IEC 27001:2022 ISMS certification since 2018; certificates via Compliance Center.

Vendor claimed

Vendor claimed

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

BSI C5
Vendor claimed

BSI C5 listed among national/international standards on compliance page.

Not listed
HDS (French health data hosting)
Vendor claimed

HDS listed on compliance page; confirm scope and zones for health workloads.

Not listed
CSA STAR
Vendor claimed

CSA STAR listed on compliance page.

Not listed
GDPR / EU data protection
Vendor claimed

Swiss entity; GDPR + Swiss FADP claims; EU zones; public DPA. Not legal advice.

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

Swiss operator, no known US parent, European workload zones, and no third-party processor for compute/storage/SKS customer data. Medium residual path via US ops providers (AWS archival, Twilio auth, PayPal) listed for client data. DBaaS uses Aiven (Finland). 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

Public DPA for Akenes SA as processor; Swiss law; Aiven listed for DBaaS.

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

Primary product is IaaS/managed infrastructure; customer AI workloads remain customer-controlled. Concrete AI offerings may need separate review if used as an AI system.

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.

BSI C5 Type IINot listed
Vendor claimed

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

TISAX Level 3Not listed
Vendor claimed

Vendor states TISAX Level 3 for Germany and Netherlands regions.

Considerations & known limitations: Exoscale vs Open Telekom Cloud
Considerations & known limitationsLogo: ExoscaleExoscaleLogo: Open Telekom CloudOpen Telekom Cloud
US third parties on client/ops path
Medium

Privacy policy lists AWS (US) data archival, Twilio (US) authentication, and PayPal (US) among client operations providers. Vendor states customer-uploaded service data is not transferred to these providers, but account/ops data paths still matter for CLOUD Act and transfer diligence.

Not listed
DBaaS subprocessor (Aiven)
Low

Managed databases depend on Aiven Oy (Finland) for orchestration while instances run on Exoscale. Confirm contractual chain, access model, and zone placement for sensitive data.

Not listed
Cert evidence mostly in customer portal / NDA
Low

ISO/SOC/C5/HDS claims are strong marketing signals, but full certificates and SOC reports typically require Compliance Center access or NDA—not fully public PDFs for all frameworks.

Not listed
Narrower PaaS than hyperscalers
Medium

Expect solid IaaS, SKS, DBaaS, storage, and GPU—not the global proprietary service catalog of AWS/Azure/GCP. Validate feature gaps early for serverless, global edge, and specialized managed services.

Not listed
Zone catalog evolves
Low

Public materials discuss further European expansion (e.g. Spain via A1 Digital messaging). Treat the live datacenters page as source of truth for residency commitments.

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

Exoscale

Best fit when

  • Teams that must pin VMs, Kubernetes, and object storage to named European zones (including Swiss options)
  • SaaS and product orgs wanting SKS plus managed PostgreSQL/MySQL/Kafka/OpenSearch without running the control planes
  • Buyers who need a published DPA, zone list, and multi-framework compliance pack from a non-US legal entity
  • Workloads that fit IaaS plus managed open-source data services rather than proprietary global PaaS catalogs
  • Organizations evaluating A1 Digital / A1 Telekom Austria group cloud as a European alternative to AWS/Azure/GCP

Poor fit when

  • Products that depend on dozens of proprietary hyperscaler services or multi-continent active-active regions
  • Buyers who require zero US-group SaaS anywhere on the account path (privacy lists AWS archival, Twilio, PayPal for ops)
  • Teams seeking a fully self-hosted OpenStack/Kubernetes distribution rather than a managed public cloud
  • Bare-metal-heavy designs better served by large European bare-metal catalogs (e.g. OVHcloud)

Consider instead when

  • When: You need extensive bare-metal or a different pan-EU hosting footprint

    Consider: OVHcloud

    Often stronger metal catalog and broader hosting packaging; different sovereignty and product mix.

  • When: You want a developer-centric alternative with a different regional product mix

    Consider: Scaleway

    Common EU shortlist peer; compare zones, K8s, and storage packaging side by side.

  • When: You need global regions and deep proprietary PaaS/AI catalogs

    Consider: Amazon Web Services, Microsoft Azure, or Google Cloud Platform

    Trade European-operator simplicity for worldwide service breadth and US CLOUD Act parent risk.

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

Exoscale

  • Download current ISO/SOC/C5/HDS certificates from the Compliance Center and verify auditor, scope, and expiry for your zones.
  • Confirm whether your use case can accept AWS/Twilio/PayPal on the account/ops path even if workload data stays on European Exoscale zones.
  • For DBaaS, document Aiven access boundaries, encryption, backup locations, and multi-zone replication behavior in writing.
  • If Spanish or other new zones are required, get contractual residency language rather than relying on roadmap announcements.
  • Clarify support plan SLAs and enterprise contracting terms beyond self-serve pay-as-you-go.

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?
