The short version

  • 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; Puppet the pricing page publishes no rate and no minimum, and asks you to fill in a form to be sent pricing and plan information
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, Puppet covers Manifests.

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

Puppet

  • The pricing page publishes no rate and no minimum, and asks you to fill in a form to be sent pricing and plan information
  • Pricing is banded by number of managed nodes, with separate tiers for under 25 nodes and 25 or more nodes
  • The product is split into Puppet Enterprise and a higher Puppet Enterprise Advanced edition, so compliance oriented features sit behind the upper tier
