### AWS Lambda ### AWS Lambda
In order to use sharp on AWS Lambda, you need to [create a deployment package](http://docs.aws.amazon.com/lambda/latest/dg/nodejs-create-deployment-pkg.html). Because sharp A [deployment package](http://docs.aws.amazon.com/lambda/latest/dg/nodejs-create-deployment-pkg.html) for the
downloads and links libraries for the current platform during `npm install` you have to [Lambda Execution Environment](http://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html)
do this on a system similar to the [Lambda Execution Environment](http://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html). The easiest ways to do this, is to setup a can be built using Docker.
small t2.micro instance using the AMI ID listed in the previous link, ssh into it as ec2-user
and follow the instructions below.
Install dependencies:
```sh ```sh
curl -s https://rpm.nodesource.com/setup_4.x | sudo bash - rm -rf node_modules/sharp
sudo yum install -y gcc-c++ nodejs docker run -v "$PWD":/var/task lambci/lambda:build-nodejs6.10 npm install
``` ```
Copy your code and package.json to the instance using `scp` and create a deployment package: Set the Lambda runtime to Node.js 6.10.
```sh To get the best performance select the largest memory available. A 1536 MB function provides ~12x more CPU time than a 128 MB function.
cd sharp-lambda-example
npm install
zip -ur9 ../sharp-lambda-example.zip index.js node_modules
```
You can now download your deployment ZIP using `scp` and upload it to Lambda. Be sure to set your Lambda runtime to Node.js 4.3.
**Performance Tip:** To get the best performance on Lambda choose the largest memory available because this also gives you the most cpu time (a 1536 MB function is 12x faster than a 128 MB function).
