NAME

VM::EC2::Instance::Located - determine if code is executing on an EC2 instance

SYNOPSIS

  my $result = VM::EC2::Instance::Located::at_ec2();
  if($result) {
    print "Running at EC2\n";
  } else {
    print "Not running at EC2\n";
  }

DESCRIPTION

Provides a function that determines if code is executing on an EC2 instance.

Currently implemented by resolving instnace-data.ec2.internal. It will succeed on an ec2 instance and fail otherwise.

METHODS

at_ec2

Determines if the code is running at EC2.

The answer is cached because typically the result does not change unless you're able to move processes between an EC2 instance an a non EC2 instance.

Returns a boolean value answering the question.
