About
AWS Lambda is a serverless compute service that runs code without requiring server provisioning or cluster management. It is designed to help teams build event-driven applications, backends, and automation workflows with minimal infrastructure overhead.
The service supports a broad range of use cases, including web and mobile backends, batch and real-time data processing, generative AI workflows, and other event-driven workloads. It integrates with AWS services and external event sources so teams can focus on application logic rather than operational maintenance.
- Run code in response to events without managing servers.
- Scale automatically with workload demand.
- Support web, mobile, data, and AI-driven serverless applications.
- Integrate with AWS services and third-party event sources.
Free Tier Value
The page explicitly states the Lambda free tier includes 1,000,000 free requests/month and 400,000 GB-seconds/month, plus 100 GiB of HTTP response streaming beyond the first 6 MB per request. Using the provided rule for usage-based free tiers, the conservative monthly value is the sum of free quotas at paid rates: 1,000,000 requests × $0.20/M = $0.20 and 400,000 GB-s × $0.0000166667 ≈ $6.67, for about $6.87/month; the streaming allowance is not priced on the page, so it is excluded. No signup-page statement about credit card requirements appears in the provided text, so no_cc_required is false.
What's included in the free tier
- One million free requests per month for Lambda function invocations.
- 400,000 GB-seconds of compute time per month for x86 and Graviton2 functions, in aggregate.
- 100 GiB of HTTP response streaming per month, beyond the first 6 MB per request, which are free.
See AWS Lambda pricing for current limits.
