Pros & Cons
CloudSigma
Pros
- CPU, RAM and storage are sized independently rather than in fixed instance types.
- Per-second metering in five-minute billing segments avoids paying for idle hourly blocks.
- A wide certification list covers ISO 27001, 27017 and 27018, SOC 2 and PCI-DSS.
- The white-label model lets telcos and MSPs launch branded cloud services on revenue share, with no licence fees.
- Terraform, Ansible and a REST API with pricing and billing endpoints support automation.
Cons
- No public list prices, so costs require a pricing call.
- Burst usage is charged at higher rates than subscription capacity, which makes bills harder to predict.
- The public review footprint is small, and many reviews are years old.
- The network uptime guarantee does not cover applications, per RFP.wiki.
- Some users report friction during setup and support in edge cases.
Nebius
Pros
- Newest NVIDIA hardware, including B300 and GB300 NVL72, is listed with published per-hour prices.
- Network egress, ingress and public IPs are free, which removes a common hidden cost on hyperscalers.
- The certification list is broad: SOC 2 Type II, SOC 3, several ISO standards including 27001 and 42001, and CSA STAR.
- EU data centers in Finland and Paris help with GDPR and data residency.
- Infrastructure as code is fully supported through a CLI, a Terraform provider, gRPC and REST APIs, and SDKs.
Cons
- The catalogue is narrow outside AI. The only managed database is PostgreSQL, and there is no CDN or web hosting.
- Some users report slower support responses than AWS or CoreWeave.
- Users note documentation gaps for advanced setups.
- Kubernetes and Slurm workflows assume DevOps expertise.
- Commitment pricing and the largest clusters require contacting sales.
