CloudSigma

CloudSigma started in 2009 as a public cloud provider. Its servers are sized by the resource, so customers choose CPU, RAM and storage independently and get full root access. It has since repositioned as a sovereign cloud platform that service providers resell under their own brand. Telcos, managed service providers, datacenter operators and distributors get a branded portal, set their own end-user prices and keep the customer relationship. CloudSigma runs the platform and billing engine. The stack covers KVM and VMware compute, VPC networking, ARM options, and GPU compute with passthrough, vGPU and MIG. Storage includes block, object and backup services with snapshots. A newer Intelligence as a Service layer exposes more than 40 AI models through one OpenAI-compatible API. CloudSigma says it runs in over 40 regions across more than 35 countries with in-country data residency. It lists ISO 27001, 27017, 27018, SOC 2 and PCI-DSS certifications. Pricing is utility-style and metered per second in five-minute billing segments. Providers pay per-unit wholesale rates on a revenue-share model, with no platform licence fees or minimum commitments. The API documents subscription prices and higher burst prices, plus discounts for commitments of 3 months to 3 years. The main limitation for buyers is that no list prices are published, so rates come from a pricing call. Its public review base is also small and largely dated compared with DigitalOcean, OVHcloud or the hyperscalers. Automation runs through a REST API, Terraform and Ansible.
