VM::EC2::Security::CredentialCache -- Cache credentials respecting expiration time for IAM roles.


Retrieves the current EC2 instance's IAM credentials and caches them until they expire.

  use VM::EC2::Security::CredentialCache;

  # return a VM::EC2::Security::Credentials if available undef otherwise.
  my $credentials = VM::EC2::Security::CredentialCache->get();


This module provides a cache for an EC2's IAM credentials represented by VM::EC2::Security::Credentials. Rather than retriving the credentials for every possible call that uses them, cache them until they expire and retreive them again if they have expired.
