AWS Lambda Serverless Cost Calculator
Calculate serverless compute costs in GB-seconds. Compare x86 versus Graviton2 ARM architecture pricing and forecast monthly AWS cloud bills.
AWS Lambda Serverless Cost & Graviton2 Architecture Calculator
Calculate monthly serverless compute bills in GB-seconds. Compare x86 vs Graviton2 ARM64 pricing and AWS Free Tier savings.
Optimizing Serverless Compute Costs in the Cloud
Serverless architectures eliminate idle server costs, but high-throughput APIs can quickly rack up substantial bills. Tuning memory allocations and switching to ARM-based Graviton2 runtimes are essential FinOps best practices.
Key Features
Graviton2 ARM64 20% Discount
Demonstrates immediate compute savings by switching functions from x86 to AWS Graviton.
AWS Free Tier Integration
Accounts for the permanent 1M requests and 400,000 GB-seconds monthly free tier.
Common Use Cases
- ✓Cloud Architects & DevOps Engineers
Size memory allocations to balance function duration speed against billable GB-seconds.
- ✓FinOps & Engineering Managers
Forecast monthly AWS cloud spend for high-throughput serverless microservices.
Frequently Asked Questions
How is AWS Lambda billed?
AWS Lambda charges based on two factors: the number of requests (inbound invocations) and the compute duration, measured in GB-seconds (allocated RAM multiplied by milliseconds of execution time).
Why is Graviton2 cheaper for Lambda?
AWS Graviton2 processors (ARM64 architecture) offer up to 34% better price-performance and are billed at a flat 20% discount compared to x86_64 processors for Lambda compute.
