Images include Ubuntu LTS and CUDA-ready builds for fast start, with optional preinstalled ML stacks.
Sample VM Options
- Budget: TensorDock (Manassas) – 8 vCPU, 24 GB RAM, 500 GB storage, Ubuntu 22.04/24.04 LTS image, $0.64 per hour
- Mid-range: TensorDock (Delaware) – 8 vCPU, 24 GB RAM, 500 GB storage, Ubuntu 22.04/24.04 LTS image, $1.02 per hour
- Performance: Sesterce (New York) – 16 vCPU, 90 GB RAM, 500 GB storage, CUDA-ready Ubuntu image, $5.71 hour
Supply comes from enterprise operators such as Sesterce and TensorDock across multiple certified facilities worldwide, with locations like Gdansk, New York, Montreal, and more. Each listing exposes provider, region, and configuration, so teams can pick proximity and specs that match their SLAs.
