AWSTemplateFormatVersion: 2010-09-09 Description: >- AWS CloudFormation Sample Template AutoScalingMultiAZWithNotifications: Create a multi-az, load balanced and Auto Scaled sample web site running on an Apache Web Serever. The application is configured to span all Availability Zones in the region and is Auto-Scaled based on the CPU utilization of the web servers. Notifications will be sent to the operator email address on scaling events. The instances are load balanced with a simple health check against the default web page. Parameters: VpcId: Type: 'AWS::EC2::VPC::Id' Description: VpcId of your existing Virtual Private Cloud (VPC) ConstraintDescription: must be the VPC Id of an existing Virtual Private Cloud. Subnets: Type: 'List<AWS::EC2::Subnet::Id>' Description: The list of SubnetIds in your Virtual Private Cloud (VPC) ConstraintDescription: >- must be a list of at least two existing subnets associated with at least two different availability zones. They should be residing in the selected Virtual Private Cloud.
