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.

IONOS

  • Virtual Data Center Designer and IaaS compute

    Build isolated virtual data centers in the browser or via Cloud API: dedicated-core servers, vCPU servers, and Cubes with attached NVMe. Live vertical scaling is supported on many Linux images for cores, RAM, NICs, and volumes without a full rebuild. Locations span DE (Berlin, Frankfurt, Karlsruhe), FR, ES, UK, and US.

  • Managed Kubernetes without a separate control-plane fee

    Automated cluster and node-pool setup with geo-redundant control plane, admin API access, and optional node auto-scaling. IONOS documents the managed control plane as free of charge; you pay for the underlying compute, storage, and network only—useful for staging and production clusters on the same contract.

  • S3-compatible Object Storage across EU and US endpoints

    Contract-included Object Storage with S3 API compatibility, versioning, object lock, SSE-S3/SSE-C, and lifecycle rules. Documented endpoints include Frankfurt, Berlin, Logroño, and Lenexa (US). German object-storage locations are listed with BSI IT-Grundschutz compliance notes in the service catalog.

  • Managed databases, GPU VMs, and Berlin-hosted AI Model Hub

    DBaaS for PostgreSQL, MongoDB, MariaDB, and in-memory DB; Cloud GPU VMs (NVIDIA H200 templates) in Frankfurt; AI Model Hub with OpenAI-compatible APIs, RAG/vector support, and vendor-stated processing exclusively in Germany (Berlin). Fits teams that want European inference without standing up their own GPU estate.

  • Domains, web hosting, and personal consultant for SMBs

    Classic IONOS portfolio: domain registration, shared/VPS/dedicated hosting, site builders, and optional Microsoft 365 or Google Workspace. Differentiator for non-cloud buyers is a dedicated personal consultant plus 24/7 support channels—not pure ticket-only self-serve hosting.

Assurance & compliance: Aruba Cloud vs IONOS
Assurance & complianceLogo: Aruba CloudAruba CloudLogo: IONOSIONOS
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.

Partial

BSI C5 Type 1 (2023 announcement) and IT-Grundschutz ISMS claims after external audit; not a public no-logs VPN-style audit. Request current reports and scope.

ISO 27001
Vendor claimed

Vendor publishes ISO 27001 certificate PDF and states ISO 27001 family as a security pillar; also claims 27017/27018/27035. Re-verify cert scope and validity dates in procurement.

Vendor claimed

Vendor FAQ/about materials state ISO 27001 for data centers / security posture; facility partner cert PDFs also referenced on location pages. Independent cert registry entry not re-verified here.

SOC 2 / SOC 3
Not found

Public SOC 2/3 report not found on product pages. Vendor publishes ISAE 3402 report PDF instead—request current assurance package.

Not found

SOC/SSAE-style attestations appear for some facility operators (e.g. Equinix listings). No clear IONOS product-level SOC 2 claim found on primary pages reviewed.

ISAE 3402
Vendor claimed

Certificate/report PDF linked from data-protection resources page.

Not listed
GDPR / EU data protection
Vendor claimed

EU/Italian entity; services designed under GDPR; CISPE Code of Conduct claimed; processor terms in cloud T&Cs.

Vendor claimed

German controller/processor entities; EU location options; vendor GDPR statements. Residency still depends on selected regions and subprocessors.

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 SE / no known US parent, but US subsidiaries, US host regions (LAS/EWR/MCI), Equinix facility partnership, optional Microsoft/Google products, Acronis-powered backup. 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

Hosting DPA via account privacy flows; IONOS Cloud AVV via account manager / contract docs. Confirm entity and service annex.

CISPE Code of Conduct
Vendor claimed

Vendor states CISPE Code of Conduct compliance on product and sovereignty pages.

Not listed
ACN qualification (Italian PA)
Vendor claimed

Vendor claims infrastructure up to ACN AI3 and services up to QC3 for public administration. Confirm which products are in scope for your project.

Not listed
EU AI Act
Not applicable

Infrastructure provider; Framework AI tool exists as optional capability with customer-responsibility language—not an AI product evaluation.

Partial

Relevant mainly to AI Model Hub (docs discuss governance/compliance). Core hosting/IaaS is not AI-product-centric; treat AI Act as service-specific diligence.

BSI C5 (Cloud Computing Compliance Criteria Catalogue)Not listed
Vendor claimed

Company IR announcement 7 Nov 2023: C5 Type 1 for Compute Engine, Cloud Cubes, S3 Object Storage after external audit. Type 1 = design at a point in time; confirm current validity and product scope.

Considerations & known limitations: Aruba Cloud vs IONOS
Considerations & known limitationsLogo: Aruba CloudAruba CloudLogo: IONOSIONOS
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
US regions, US entities, and facility partnersNot listed
Medium

Selecting US locations places data in the US. Even EU-only deployments sit in a group that has US subsidiaries and uses partners such as Equinix for some EU facilities—material for CLOUD Act / transfer reviews.

No clear public subprocessor catalogueNot listed
Medium

Unlike many pure SaaS vendors, a single customer-facing subprocessor list was not found. Buyers must extract partners from location pages, DPA annexes, and product docs (Equinix, Acronis, Microsoft, Google, etc.).

C5 Type 1 scope and freshnessNot listed
Low

Public C5 claim is Type 1 for specific products (Compute Engine, Cubes, Object Storage) as of the 2023 announcement. Not a blanket certificate for every IONOS product; request up-to-date reports.

Narrower managed ecosystem than hyperscalersNot listed
Low

Strong IaaS and selected PaaS, but not a full AWS/Azure service catalogue. Multi-region global apps and niche managed services may force multi-cloud or a different primary vendor.

Hosting brand vs cloud platform complexityNot listed
Low

SMB hosting contracts, reseller office suites, and enterprise cloud AVVs are different commercial and compliance surfaces—do not assume one DPA covers every SKU.

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.

IONOS

Best fit when

  • SMB and agencies needing domains, hosting, email/office resale, and a personal consultant under one German brand
  • Teams building IaaS workloads in selectable EU locations with a visual Data Center Designer and full Cloud API
  • Organizations that want managed Kubernetes, DBaaS, and S3-compatible storage without a hyperscaler contract
  • DACH public-sector or regulated buyers who need documented BSI C5 / IT-Grundschutz posture on scoped cloud products (confirm current report)
  • AI or inference pilots that prefer vendor-stated Germany (Berlin) hosting for AI Model Hub

Poor fit when

  • Buyers requiring a guarantee of no US legal entities, no US regions, and no US-group facility partners anywhere in the path
  • Workloads that depend on the full AWS/Azure/GCP marketplace, global region density, or niche managed services IONOS does not offer
  • Price-only bare-metal or Hetzner-style DIY shops that do not need managed PaaS or SMB hosting layers
  • Teams that refuse any US-group SaaS (Microsoft 365 / Google Workspace) if those bundles are part of the intended stack

Consider instead when

  • When: You want French-operated cloud with strong developer packaging and EU focus without a mass-market hosting brand

    Consider: Scaleway

    Different product mix; compare region map and managed services side by side.

  • When: You prioritize large European hosting/cloud scale and multi-country DC ownership narratives

    Consider: OVHcloud

    Both are EU groups with non-trivial international footprints—read residency options carefully.

  • When: You mainly need cost-efficient dedicated servers or simple cloud in DE/FI with minimal PaaS

    Consider: Hetzner

    Thinner managed layer; different support and SMB hosting model.

  • When: You are already in Schwarz Group ecosystems or need STACKIT-specific public-cloud positioning

    Consider: STACKIT

    Narrower commercial brand than IONOS hosting+cloud combo.

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?

IONOS

  • What is the current BSI C5 report type (Type 1 vs Type 2), validity period, and exact product/location scope?
  • Can IONOS provide a consolidated subprocessor and sub-processor change-notification list under the DPA/AVV?
  • Which contract entity (IONOS SE vs IONOS Cloud GmbH vs national affiliates) will sign for our workload and which TOMs apply?
  • For EU-only deployments, are any support, monitoring, or backup control-plane components processed outside the EU?
  • Is ISO 27001 held by IONOS operating companies for the full service stack, or primarily facility/operator certifications?
