AWS Lambda Pricing Plans & Tiers
Serverless compute service that runs code on demand
Pricing last verified: March 16, 2026
Pricing Analysis
AWS Lambda's pricing model ($0 free tier with 1M monthly requests, per-execution billing thereafter) represents the paradigm of consumption-based serverless pricing. The free tier removes evaluation friction, while the per-execution model ($0.20 per million requests, $0.00001667 per 100ms execution time) creates cost unpredictability that frustrates startups. A viral application incurring 1 billion monthly requests would cost $200K in request fees plus execution charges, making Lambda budgeting an exercise in worst-case scenarios.
AWS Lambda's strength is integration breadth: direct event sources (S3, DynamoDB, API Gateway, SNS, SQS) enable serverless workflows without external orchestration. However, this tight coupling increases switching costs and platform lock-in. Teams that build Lambda-centric architectures across multiple AWS services find migration economics prohibitive, enabling AWS to extract premium pricing in year 2-3 of production deployments.
Lambda's per-execution billing incentivizes optimization but creates operational complexity: teams must constantly tune memory allocation, timeout settings, and cold start behavior to minimize cost. This optimization burden is an invisible operational cost that competes against flat-rate platforms (Cloudflare Workers $5/mo, Deno Deploy $20/mo) that trade margin efficiency for simplicity.
Strengths
- Free tier with 1M monthly requests enables meaningful development and low-traffic production deployments.
- Tight integration with AWS services (S3, DynamoDB, API Gateway) simplifies event-driven architecture.
- Per-execution pricing rewards optimization and scales to zero on idle.
Considerations
- Per-execution billing creates cost unpredictability for viral or bursty workloads.
- Cold start latency and memory optimization require constant operational tuning.
- Tight AWS coupling increases switching costs and enables premium pricing as workloads mature.
AWS-native deployments and event-driven workloads where integration with AWS services justifies per-execution cost complexity.
Lambda's free tier captures developers; per-execution billing creates cost unpredictability that locks in long-term customers.
