Detailed Comparison

1. Pricing Models

• RunPod:

  • On-Demand vs Spot Instances: RunPod offers both on-demand instances, which are priced higher but guarantee resource availability, and spot instances, which are more affordable but can be interrupted with a 5-second termination notice. Billing is per-minute for both options.
  • Savings Plans: They provide upfront payment discounts through savings plans that are flexible and apply to subsequent deployments using the same GPU card type. These plans have a fixed expiration date.

• Lambda:

  • Public Cloud Options: Lambda's on-demand cloud services follow a pay-per-minute billing model with no minimum usage requirements. They also offer 1-Click Clusters ranging from 16 to 512 GPUs and Private Cloud options with 512 to over 2000 GPUs, requiring 1-3 year commitments.

2. Storage Solutions

• RunPod:

  • Running Pods: Charged at $0.10 per GB per month.
  • Stopped Pods: Priced at $0.20 per GB per month.
  • Network Volumes:
  • Less than 1TB: $0.07 per GB per month.
  • More than 1TB: $0.05 per GB per month.

• Lambda:

  • File Systems: Billed at $0.20 per GB used per month with hourly increments. Root volumes are included with instances, simplifying the storage pricing structure.

3. Flexibility and Commitments

• RunPod:

  • Flexibility: Offers both spot and on-demand instances with the added advantage of savings plans, providing flexibility without requiring long-term commitments.

• Lambda:

  • Commitments: While Lambda provides flexibility through various public cloud options, their Private Cloud services require longer-term commitments (1-3 years), which may be less flexible for some users.
