IONOS

What IONOS actually is

In our /category/vps-providers field, IONOS is the big European incumbent. The brand sits inside IONOS SE (Montabaur, Germany), part of the United Internet group, with the IONOS Group SE entity listed on the Frankfurt Stock Exchange since February 2023. The scale is enterprise-grade: over 6.5 million customer contracts, more than 100,000 servers, ISO 27001-certified data centres, and — per IONOS's own VPS pages — 31 data centres across North America and Europe powered by 100% renewable energy. This is not a scrappy cloud startup; it is the German answer to GoDaddy, minus the reputation for squeezing customers, plus a real IaaS platform underneath.

The VPS product line itself is called VPS+, built on the same technological platform as IONOS Cloud with a deliberately reduced feature set and simpler pricing. It is full virtualization (KVM) with root access, NVMe storage, unlimited traffic, and no setup fees, sold on one-year terms with a 30-day money-back guarantee. Above it sits IONOS Cloud proper — per-minute billed compute, block storage, private networks, Terraform support, and NVIDIA H200 GPU VMs — and below it the shared hosting we review separately at /category/shared-hosting. For this review we focus on VPS+, with the cloud platform noted where it changes the picture.

Pricing: what you really pay

The advertised entry is $2/mo, and the fine print is worth reading: that is the VPS S+ plan (1 vCore, 2GB RAM, 60GB NVMe) at $2/mo for the first three months on a one-year term, then $6/mo. The promotional ladder continues upward — VPS M+ lands around $4/mo during the intro window with 2 vCores, 4GB RAM, and 120GB NVMe — and tops out at VPS XXL+ (12 vCores, 24GB RAM, 720GB NVMe), listed at $20/mo for the first three months against a $68/mo reference price, a headline saving of $144.

Three months of intro pricing is a much gentler structure than the shared-hosting line's year-one cliff, and the steady-state numbers are defensible: $6/mo for 2GB with 60GB NVMe, unmetered traffic, a dedicated IPv4, and an entire IPv6/80 network included is fair if not spectacular next to the /benchmarks leaders (Hetzner's CX22 gives 4GB for €4.35/mo). At the top end, roughly $68/mo for 12 vCores and 24GB is competitive with mainstream VPS pricing, though the same money in our benchmark database buys more from the value specialists.

What you get in the price is unusually complete. Every plan includes full root access, KVM console, the Cloud Panel, Windows Server 2022 or 2025 availability (at Windows license cost), 1 IPv4 address plus 1 IPv6/80 network, 2 email addresses, wildcard SSL, firewall management, IPS/IDS, and DDoS protection. Server images — point-in-time snapshots for rollback and recovery — are part of the platform. The main paid add-on is Plesk Obsidian at $6/mo if you want a graphical admin panel, additional IPv4 addresses at $5/mo each, and optional Cloud Backup from $0.065/GB/month. There is also a new one-click app catalog (pre-configured stacks — databases, automation tools, AI tooling) that gets a box running without hand-installing anything.

Performance & infrastructure

Storage is NVMe across the VPS+ range (60GB up to 720GB), traffic is unmetered with no overage billing, and the virtualization is KVM with what IONOS describes as full virtualization and no caps on vertical growth within the plan ladder. The VPS platform runs on the same foundations as IONOS Cloud, which means the option to graduate into per-minute-billed cloud compute, block storage, private networks, and managed services without changing providers — a genuine migration path that most VPS shops cannot offer.

Uptime is published at 99.99%+ across the product pages, backed by ISO 27001-certified facilities and 24/7 support included free with every plan. The geographic footprint is one of the widest in European VPS: ten primary cloud data centres in Frankfurt (x2), Berlin, Paris, London, Worcester, Logroño, Las Vegas, Newark, and Lenexa, with the company's wider estate of 31 sites serving its full product range. For EU data-residency needs — GDPR workloads, public-sector adjacent projects — the German and French locations with a German counterparty are a clean story, and IONOS publishes a data-residency policy stating customer data stays in the locations you choose.

On security, DDoS protection is not an upsell: IONOS runs a Global Scrubbing Platform for its server and cloud products (network/transport-layer protection against volumetric, UDP, and TCP attacks), plus firewall management and IPS/IDS at the instance level. Combined with the included snapshots and optional per-GB backup, the resilience toolkit is well above the budget-VPS norm.

We have not measured IONOS VPS on our own sysbench/fio/iperf3 rig — our 2026-04-01 round covered Hetzner Cloud, DigitalOcean, UpCloud, Vultr, and Linode (see /benchmarks) — so no hands-on numbers here. Editorial read: expect NVMe disk performance in line with the mainstream, and network latency that favours European and North American audiences.

The one-click app catalog deserves a paragraph of its own, because it is the clearest sign of where IONOS is steering VPS+. Rather than just shipping an OS template, the catalog offers pre-configured stacks — databases, automation tools, self-hosted utilities, and AI tooling — installable at purchase or at any point later, with multiple apps per box. For the growing crowd running self-hosted AI assistants and workflow automation on their own servers, this removes the most error-prone hour of setup. It is not a substitute for proper configuration management, and we would still harden any box exposed to the internet, but it shortens the path from "provisioned" to "doing something useful" considerably. Windows users are equally served: Windows Server 2022 and 2025 templates run on the same KVM platform over RDP, with the KVM console in the Cloud Panel as the backstop when remote access breaks. The included IPv6/80 allocation is also generous by market standards — most budget VPS providers hand out a single address — and lets you number an entire subnet of containers or services without paying per-IP fees.

Where it falls short

The promotional pricing deserves the first frown: $2/mo tripling to $6/mo after three months is mild by industry standards but still means the sticker is not the price, and the top tier's $20-to-$68 step is a real jump at renewal. Second, the developer experience is Cloud Panel-centric — serviceable for provisioning, DNS, and IP management, but less scriptable and less polished than the APIs and CLIs of DigitalOcean, Hetzner, or Vultr; the IONOS Cloud API and Terraform exist one layer up, not on the VPS+ product itself. Third, Plesk costs $6/mo, extra IPv4 addresses cost $5/mo each, and Cloud Backup is metered at $0.065/GB/month — none of it outrageous, but the true monthly cost is base plan plus the pieces you actually need.

Fourth, while 31 data centres sounds global, the deployable VPS footprint is really the ten primary sites, all in Europe and North America — nothing in Asia-Pacific, South America, or Africa for this product line. Fifth, the platform is opinionated: Windows licensing, the mail offering (2 addresses), and the app catalog are all IONOS-shaped, and support is broad rather than deep — fine for standard stacks, less so for exotic configurations.

Who should pick this

Our pick for European businesses, agencies, and developers who want VPS hosting with a German counterparty, EU data-residency options, and enterprise-scale backing — without paying enterprise prices. Small production servers, client sites, internal tools, and WordPress fleets fit well, and the included snapshots, DDoS protection, and IPv6/80 make the default configuration production-credible. The Windows VPS option is also one of the more affordable ways to run Windows Server legitimately.

We would not pick it for raw price-performance chasing (Hetzner Cloud wins in /benchmarks), for API-first automation-heavy workflows, or for audiences in Asia-Pacific. And if you are sensitive to price steps, model the post-promo rate before committing — the $2 sticker has a $6 tail.
