Aws Lambda Plans Pricing
AWS Lambda is pay-as-you-go priced on two axes — number of requests and duration in GB-seconds — with separate rates for x86 and ARM (Graviton2) architectures. Provisioned concurrency and ephemeral storage above 512 MB are billed separately. A perpetual free tier provides 1M requests and 400K GB-seconds per month. Compute Savings Plans offer up to 17% discount.
Aws Lambda Plans Pricing is the machine-readable pricing-plan profile for AWS Lambda on the APIs.io network, conforming to the API Commons Plans specification.
It defines 7 plans, covering usage-based, subscription, and freemium tiers, with named plans including On-Demand (x86), On-Demand (ARM / Graviton2), Provisioned Concurrency, Ephemeral /tmp Storage (above 512 MB), Data Transfer, and 2 more.
Tagged areas include Serverless, Functions, Compute, and Event-Driven.

- Free same-region transfer to S3 / DynamoDB / SNS / SQS / Kinesis
Up to 17% discount on Lambda compute (duration + provisioned concurrency) for 1- or 3-year commitment.
- 1-year or 3-year commitment
- Applies to duration and provisioned concurrency
Lambda free tier is perpetual, not 12-month-limited. Applies across both x86 and Graviton2.
- 1M requests per month perpetual
