Pros & Cons
Amazon Web Services (AWS)
Pros
- The service catalogue is unusually broad, with over 200 services across 38 regions, so most infrastructure needs can be met on one platform.
- EC2 has a 99.99% region-level SLA with credits of up to 100%, and instances unavailable for more than six minutes in an hour are not billed for that hour.
- The free plan gives up to $200 in credits, and more than 30 always-free services let new teams experiment at low cost.
- Support scales from a $29 minimum up to dedicated Enterprise and Unified Operations tiers for mission-critical workloads.
- G2 rates it 4.4 across more than 17,000 reviews, and reviewers praise its scalability and global reach.
Cons
- Reviewers widely cite a steep learning curve across the console and services.
- Usage pricing is complex and can produce unexpected bills unless spend is monitored closely.
- Paid support is billed as a percentage of total AWS spend, so support costs rise with usage.
- A July 2025 billing console bug showed customers estimated charges in the billions, which hurt trust in its cost tooling.
Fluidstack
Pros
- Can build and deliver capacity at gigawatt scale, which is why Anthropic chose it for its Texas and New York data centers.
- Runs managed Slurm and Kubernetes on bare metal, so training teams do not have to operate the cluster themselves.
- SemiAnalysis gave its GPU clusters a ClusterMAX Gold rating.
- Heavily funded, including an $830M Series A in January 2026, which lowers the risk that the supplier fails.
Cons
- There is no public rate card or self-serve signup, so pricing requires a sales quote.
- Public documentation on APIs, storage and compliance certifications is scarce.
- Third-party sources say its GPU catalog is narrower than marketplace providers and that on-demand billing is per hour.
- It offers no general web hosting, managed databases or app platform services.
