Your Library experience with Drupal cloud-based hosting

Hello everyone,

I am a new comer to this group, since i did not know about the existence of this Drupal- Libraries group until attended a BOF session at Drupalcon New Orleans this week.

My Library is currently looking into the possibility of moving to Acquia or Panthenon to host our drupal sites because we do not have DevOps engineer nor server administrators, and most likely would not have the resource to recruit one.

My questions to you would be that:
Are you library using a cloud-based hosting? If you, what is your overall experience?

Thanks in advance!

Neena
