Thalassa Cloud

Thalassa Cloud (operated by Thalassa Cloud Services B.V., Meander 251, Arnhem, Netherlands — KvK 99309769) is a bootstrapped, founder-led EU-sovereign public cloud built Kubernetes-native and API-first, positioned as a Dutch alternative to the hyperscalers for DevOps teams. The platform covers virtual machines, managed Kubernetes (with integrated IAM/RBAC and VPC), managed PostgreSQL, S3-compatible object storage, block and file storage, container registry, managed Prometheus and a cost explorer — all provisionable through a REST API, CLI, and official Terraform / OpenTofu / Pulumi providers. Billing is usage-based (per-minute, EUR ex-VAT): the cheapest VM is roughly €5/month, a managed Kubernetes control plane around €19.50/month, with free VPC / subnets / security-groups and free bandwidth. A "Dedicated Private Cloud" option is offered for organisations wanting isolated capacity. The sovereignty positioning is strong and clean on paper — 100% EU-owned, NL-hosted, no non-EU dependencies, GDPR-first design, NIS2 support, and Dutch Cloud Community membership — with named public-sector customers including Provincie Noord-Holland and Dienst Justitiële Inrichtingen (DJI). The caveats are maturity and assurance: founded around 2024 as a bootstrapped startup with a very small team; a single region (Arnhem, nl-ams-1) with the data-centre operator undisclosed; no published certifications (ISO 27001 / BSI C5 / SecNumCloud / SOC 2 are described as available "via partners", i.e. not currently held); a Data Processing Agreement that is referenced in the terms but available only on request; and no public sub-processors list. No GPU instances or bare-metal. Best fit: Dutch / EU teams that want a genuinely EU-owned, Kubernetes-native sovereign cloud and can accept an early-stage provider without formal certifications — not yet a fit for procurement that mandates ISO 27001 / C5 or a publicly signable DPA.
