How to Deploy Rust Applications to AWS Lambda

Deploy Rust applications to AWS Lambda by compiling to a static binary, zipping it, and uploading it as a deployment package.

1. Compile your Rust binary for the AWS Lambda runtime environment (typically x86_64-unknown-linux-gnu) using cargo build --release.
2. Create a deployment package by zipping the compiled binary located in target/release/your_binary_name using zip function.zip target/release/your_binary_name.
3. Upload the function.zip file to AWS Lambda via the AWS Console or CLI using aws lambda create-function --function-name my-rust-function --runtime provided.al2 --role arn:aws:iam::ACCOUNT_ID:role/lambda-role --handler your_binary_name --zip-file fileb://function.zip.

Note: Ensure your binary is statically linked and compatible with the Lambda runtime (e.g., provided.al2 for Amazon Linux 2).

To run Rust code on AWS Lambda, you compile your program into a single file that includes everything it needs to run. You then bundle this file into a zip archive and upload it to AWS. AWS runs your code in a lightweight environment whenever a specific event triggers it, like a file upload or a web request.
