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.

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: Exoscale vs IONOS
Assurance & complianceLogo: ExoscaleExoscaleLogo: IONOSIONOS
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.

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

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.

ISO 27017 (cloud security)
Vendor claimed

Listed on compliance site as certified cloud security controls.

Not listed
ISO 27018 (cloud PII)
Vendor claimed

Listed on compliance site for personal data protection in public cloud.

Not listed
SOC 2 / SOC 3
Vendor claimed

SOC 2 listed on compliance marketing; obtain report via Compliance Center / NDA.

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.

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

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

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 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

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

Vendor claimed

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

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

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: Exoscale vs IONOS
Considerations & known limitationsLogo: ExoscaleExoscaleLogo: IONOSIONOS
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
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

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.

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

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.

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?
