The short version

  • Only Lambda (AWS Serverless) has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lambda (AWS Serverless) billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does; Wasabi 90-day minimum storage duration with no option to delete before full period without penalty
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, Wasabi covers Hot Cloud Storage.

Where each one falls short

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

Lambda (AWS Serverless)

  • Billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does
  • Provisioned concurrency, used to avoid cold starts, is charged separately at $0.0000041667 per GB-second whether or not the function runs
  • Ephemeral storage beyond the included 512 MB is metered
  • Lambda@Edge costs $0.60 per million requests, three times the standard request rate
  • VPC use and cross-region data transfer carry EC2 charges on top

Wasabi

  • 90-day minimum storage duration with no option to delete before full period without penalty
  • Significantly smaller global footprint than AWS with only 16 regions, resulting in higher latency for users in underserved regions
  • Performance can degrade with high-volume transactions requiring throughput management strategies
  • Hot storage only, no cold/archival storage tier for long-term data at lower cost
  • Support responsiveness gaps with teams experiencing multi-day waits for critical issue resolution
