Overview & Methodology
AWS Graviton2 processors (ARM64 architecture) deliver up to 19% better performance at 20% lower cost compared to standard x86 processors: $0.20 per 1M requests and $0.0000133334 per GB-second.
Mathematical Formulation
Compute Cost = Total GB-Seconds × $0.0000133334. Total Monthly = Invocation Cost + Compute Cost.Optimization Best Practices
Switching architecture in SAM, Serverless Framework, or Terraform requires just setting `Architectures: [arm64]`.
Python, Node.js, and Java runtimes run on ARM64 with zero code modifications.
Graviton2 features higher memory bandwidth, often resulting in shorter runtime durations.
Frequently Asked Questions
Q.How much does 10M executions cost on Graviton2 at 512MB and 100ms?
10M requests cost $2.00 invocation + $6.67 compute (500,000 GB-s), totaling $8.67/month (saving $1.66 vs x86).
Q.Do all AWS Lambda runtimes support ARM64?
Yes. Python, Node.js, Java, Go, Rust, .NET, and custom Docker container images all support ARM64.
Q.Does the AWS Lambda Free Tier apply to Graviton2?
Yes. The 400,000 GB-seconds monthly free tier applies equally to Graviton2 functions.
