Net::Amazon::EC2 - Perl interface to the Amazon Elastic Compute Cloud (EC2) environment.
This document describes version 0.10 of Net::Amazon::EC2, released September 23rd, 2009. This module is coded against the Query API version of the '2009-07-15' version of the EC2 API last updated September 3, 2009.
use Net::Amazon::EC2; my $ec2 = Net::Amazon::EC2->new( AWSAccessKeyId => 'PUBLIC_KEY_HERE', SecretAccessKey => 'SECRET_KEY_HERE' ); # Start 1 new instance from AMI: ami-XXXXXXXX my $instance = $ec2->run_instances(ImageId => 'ami-XXXXXXXX', MinCount => 1, MaxCount => 1); my $running_instances = $ec2->describe_instances; foreach my $reservation (@$running_instances) { foreach my $instance ($reservation->instances_set) { print $instance->instance_id . "\n"; } } my $instance_id = $instance->instances_set->[0]->instance_id; print "$instance_id\n"; # Terminate instance my $result = $ec2->terminate_instances(InstanceId => $instance_id);
If an error occurs while communicating with EC2, the return value of these methods will be a Net::Amazon::EC2::Errors object.
This module is a Perl interface to Amazon's Elastic Compute Cloud. It uses the Query API to communicate with Amazon's Web Services framework.

Disables monitoring for a running instance. For more information, refer to the Amazon CloudWatch Developer Guide.
Set AWS_ACCESS_KEY_ID and SECRET_ACCESS_KEY environment variables to run the live tests. Note: because the live tests start an instance (and kill it) in both the tests and backwards compat tests there will be 2 hours of machine instance usage charges (since there are 2 instances started) which as of September 23rd, 2009 costs a total of $0.20 USD
Important note about the windows-only methods. These have not been well tested as I do not run windows-based instances, so exercise caution in using these.
