 A number of third-party technologies can be configured to send line protocol directly to InfluxDB.
 
-## AWS Lambda

-CloudFormation is AWS’ infrastructure as code service that lets you define almost any AWS component in a configuration file. The result is a service that provides a concrete, repeatable definition of your environment that can prove useful in many scenarios. For example, if someone accidentally deletes your Simple Queue Service topic or an EC2 instance, you can easily recreate them by running your CloudFormation template.
+## AWS Lambda via CloudFormation template
 
+Write to InfluxDB with AWS Lambda, Amazon Web Services' serverless offering. AWS Lambda is Amazon Web Services' serverless offering, letting you run code without managing a server. CloudFormation templates create AWS stacks that wrap the AWS components defined in the template.

+The template contains the following sections:
+
+- Lines 1-20: Define variables that the template asks for when it's installed.
+- Lines 21-120: Handle a quirk of Lambda deployments that requires the Lambda assets to be in your region before deployment. As there is no elegant workaround, these 100 lines create an S3 bucket in your account in the region you're creating the stack and copies in these resources.
+- Lines 121-132: Define a role with basic permission to run the Lambda.
+- Lines 133-144: Define a Python library layer. This layer packages the Python HTTP library, a Python S2 Geometry library, and the InfluxDB Python client library.
+- Lines 145-165: Define the Lambda function, a short Python script zipped up in a file called `geo_lambda.zip`.
+- Lines 166-188: Define an event rule with permission to run the Lambda every hour.

-Now that we have explored the template, let’s deploy it.
 
 1. Log into your free AWS account and search for the CloudFormation service. Make sure you’re in the AWS region you want to deploy the Lambda to⁠.
 2. Click **Create Stack**.
 3. In the **Prerequisite - Prepare Template** section, select **Template is ready**.
 4. In the **Specify template** section:
