Schena, Manager of Systems at Constant Contact, is pleased with the impact of the
change. “Separation of configuration from code was a huge win for us, allowing the
company to keep moving forward to provide features and work on different parts of
the solution at the same time.”
• Productivity – Constant Contact realized that its traditional practice of using scripts,
executed using “SSH and a for loop” were no longer adequate. Utilizing Puppet has
allowed a team of two sys admins to manage all of the email infrastructure. According
to Connors, “It would take several more sys admins to do this work without Puppet.”
• Agility – Connors comments, “We expected a benefit from the new approach to
configuration management. We have been very surprised at how much of an impact it
has had on our team. Puppet has given Operations the agility we need to accomplish
our tasks.
