  • Each has a real cost: Fly.io egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are; IBM Cloud the USD 200 starter cloud credit is valid for 30 days only
  • They diverge on capability: Fly.io covers Global deployment, IBM Cloud covers Virtual Servers.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fly.io

  • Egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are
  • Stopped machines still bill at $0.15 per GB of root filesystem a month, so a paused service is not a free one
  • Volumes are billed on provisioned capacity rather than usage, at $0.15 per GB a month
  • Reservation discounts of 40% require paying a year up front, from $36 to $1,440
  • Fly Kubernetes is a separate $75 a month per cluster
  • Dedicated IPv4 addresses are $2 a month each

IBM Cloud

  • The USD 200 starter cloud credit is valid for 30 days only
  • The larger promotional credits are time boxed: USD 1,000 for Bare Metal Servers for VPC over 120 days, USD 2,500 for Power Virtual Server over 90 days, and USD 5,000 for Backup and Recovery over 90 days
  • The USD 5,000 Backup and Recovery promotion is valid for new clients only and requires a checkout promo code
  • The listed promotions carry an expiry date of 31 December 2026
  • Beyond the free tier the account is pay as you go, so cost tracks usage with no published cap
