CoreWeave

Pros

• Free internet egress and internal data transfer, which lowers the cost of moving large datasets and model checkpoints.
• Large inventory of current NVIDIA hardware, from L40S to GB200 NVL72, with InfiniBand for multi-node training.
• Spot rates are well below on-demand rates, for example $19.71 versus $49.24 per hour for an 8-GPU H100 node, and committed discounts reach up to 60%.
• The CKS control plane and SUNK Slurm scheduler are free, so you pay only for compute.
• A Terraform and OpenTofu provider manages clusters, VPCs, storage, and inference as code.

Cons

• No free tier or trial credits, and minimum spend is reported to be high even for light use.
• No managed databases, serverless functions, or CDN, so a second cloud is often needed.
• Regions are concentrated in North America and Europe, with limited Asia-Pacific coverage.
• The best pricing usually requires multi-year contracts and an enterprise sales process.
• Few public user reviews are available on G2 or Gartner to validate claims.

IONOS

Pros

• VPS+ plans include root access, DDoS protection, a firewall and unlimited traffic from $2 a month as an introductory price
• The IONOS Cloud platform covers managed Kubernetes, S3-compatible object storage and managed databases, with a Terraform provider
• Data centers in the US, UK, Germany, Spain and France, plus GDPR and data-sovereignty commitments, suit EU buyers
• Some users say 24/7 support responds quickly and is technically knowledgeable

Cons

• The introductory price can rise sharply at renewal (the Plus plan goes from $1 to $14 a month)
• Reviews and complaints repeatedly mention aggressive auto-renewal and cancellations that are hard to complete
• The control panel is described as dated
• The lowest shared hosting plan has no CDN and only one email account
• Ratings are mixed, with a G2 average of about 3.5 out of 5
