"""
Suspend an auto scaling group's scaling processes that can interfere with CodeDeploy deploys.
It assumes a single ASG per deployment group.

To use this:
* create a lambda function with this code, then hook up it up to an SNS topic that receives all deployment events (but not host events).
* attach that topic as a trigger in your deployment groups.

Unlike AWS's in-appspec approach, this supports arbitrary deploy concurrency.

How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
3. VPC with NAT, The best of both worlds, AWS services and web.

# Use AWS CLI to get the most recent version of an AMI that

# --query, --output text, and the fact that RFC3339 datetime
# fields are easily sortable.
