Aruba Cloud

  • OpenStack public cloud + CMP

    Self-service Cloud Servers and Virtual Data Centers on OpenStack with AMD/NVMe-oriented SKUs, unlimited traffic on documented cloud-server lines, and management via the Aruba Cloud Management Platform, APIs, and prepaid credit wallet. Suits test/prod VMs and progressive scale-out inside Aruba's ecosystem—not a hyperscaler global catalog.

  • VMware private cloud (Pinnacle Partner)

    Hosted Private Cloud, Virtual Private Cloud via VMware Cloud Director, unified storage, and DRaaS-style options using enterprise stacks (vendor materials cite Zerto, Veeam, vSphere tooling). Built for teams standardizing on VMware who want European hosting without running their own gear.

  • Bare metal and GPU for private AI

    Dedicated servers in Italian Rating 4 data centers (Arezzo/Bergamo and others) with configurable networking (firewall/switch add-ons) and GPU SKUs aimed at private AI/ML. Full root control and isolation; buyer owns OS security and backups unless add-on protection is purchased.

  • Managed Kubernetes and cloud-native stack

    Managed Kubernetes, Application Platform (container/PaaS), container registry, agentless backup for K8s/VDC, plus ArubaKube R&D around open-source multi-cluster projects such as Liqo. Good for EU teams wanting managed containers without leaving Aruba's network.

  • Object/block storage and enterprise backup

    S3-compatible object storage, block volumes, smart storage, and backup packages (vendor stacks include Veeam and Commvault). Use for data protection and hybrid DR—not automatic full-workload backup unless you buy and configure those services.

  • European region choice with Italian ACN path

    Place workloads across proprietary Italian and Czech sites plus partner zones in France, Germany, the UK, and Poland. Italian ACN-qualified IaaS/PaaS/SaaS positioning targets public administration and regulated suppliers; confirm exact qualified SKUs and region pins in procurement.

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: Aruba Cloud vs Open Telekom Cloud
Assurance & complianceLogo: Aruba CloudAruba CloudLogo: Open Telekom CloudOpen Telekom Cloud
Independent security / no-logs audit
Not applicable

IaaS/PaaS provider—not a no-logs consumer VPN. Request customer audit rights / SOC reports under NDA if needed.

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

Italian entity, no known US parent, primary hosting on Aruba-owned EU DCs—not on AWS/GCP/Azure by default. Residual uncertainty: subprocessor list only on request; partner DCs include UK; optional multi-cloud/hybrid to hyperscalers. Indicative only—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

Cloud/data-centre T&Cs Art. 21 appoint Aruba as processor/sub-processor for applicable services; subprocessors available on request with change notice. Confirm signed pack for your SKUs.

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.

Considerations & known limitations: Aruba Cloud vs Open Telekom Cloud
Considerations & known limitationsLogo: Aruba CloudAruba CloudLogo: Open Telekom CloudOpen Telekom Cloud
Subprocessor list not fully public
Medium

T&Cs say the updated subprocessor list is available on request, not as a public transparency page. Procurement should obtain the current list, countries, and change process before go-live.

Not listed
Partner zones and multi-region choice
Low

European network includes partner sites and a UK zone. Residency and latency goals require explicit region selection—not assumptions from marketing 'sovereign cloud' language alone.

Not listed
Customer-owned backups and OS security
Medium

Default terms state Aruba does not back up customer data unless a backup service is purchased; customers administer OS, apps, and credentials under shared responsibility.

Not listed
Narrower managed PaaS than hyperscalers
Low

OpenStack + VMware + bare metal + K8s cover classic IaaS/private cloud well, but teams expecting AWS/Azure-class managed service density will hit catalog limits.

Not listed
Certificate scope must be verified
Low

ISO/ISAE/ACN claims are vendor-published; map each cert to exact products, locations, and expiry before relying on them in a risk register.

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

Aruba Cloud

Best fit when

  • Italian or EU orgs that want compute under Aruba S.p.A. with primary hosting on Aruba-owned Italian/Czech data centers
  • Public administration and regulated suppliers needing ACN-qualified cloud SKUs (confirm product scope)
  • VMware shops seeking Hosted Private Cloud / VPC / DRaaS without US hyperscaler tenancy
  • Teams mixing OpenStack VMs, Managed Kubernetes, object storage, and bare metal/GPU for private AI
  • Buyers who value Italian-language 24/7 support, CMP self-service, and prepaid credit cost control

Poor fit when

  • Workloads that need a hyperscaler-wide global region map and deep managed PaaS catalogs (AWS/Azure-class)
  • Teams that require a fully public, always-updated subprocessor page without a customer request
  • Buyers who only want lowest-cost bare metal/VPS and do not need VMware, ACN, or enterprise packaging (Hetzner-class shortlists)
  • Strict Italy-only residency without validating region selection (partner zones include FR/DE/UK/PL)

Consider instead when

  • When: You need larger multi-country European scale or a broader global PoP footprint than Aruba's network

    Consider: OVHcloud

    French-scale European IaaS; different PA quals and product tree.

  • When: You prioritize developer-centric instance catalogs and simpler Paris/Amsterdam-style public cloud

    Consider: Scaleway

    Stronger developer UX; less Italian ACN/VMware private-cloud depth.

  • When: You need US hyperscaler ecosystem density, global managed services, and marketplace breadth

    Consider: Amazon Web Services (AWS) or Microsoft Azure

    US-parent platforms with different jurisdictional posture.

  • When: You mainly want cost-oriented German bare metal/VPS with less enterprise packaging

    Consider: Hetzner

    Different country anchor and compliance story; compare catalogs carefully.

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

Aruba Cloud

  • What is the current named subprocessor list (group companies and third parties) for the exact SKUs we will buy?
  • Which products and sites are in scope for the latest ISO 27001 / 27017 / 27018 certificates and ACN AI3/QC3 qualifications?
  • Can we pin workloads exclusively to Italian proprietary DCs (IT1–IT4) with contractual residency language?
  • What customer audit rights, ISAE/SOC report access, and DPA signature process apply to our legal entity?
  • For hybrid designs, which interconnect options touch US-group clouds, and can those be excluded?

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?
