We have our own people that handle deployment. We have a team of 10 people who manage the infrastructure. They're called the infrastructure group. The IT team is called EIG — Enterprise Infrastructure Group. All of us pretty much continuously building servers and working on different use cases. 

Some maintenance is required. We have to update the infrastructure. It's a bit of a pain point to make sure that everything works once we've upgraded it because Puppet has been evolving pretty fast. From one version to another, a lot of things can break when we upgrade them.  Although it comes with tools that can be used to verify that the code is supported, even after verification, it still breaks sometimes. 

Vendor Team. Expertise was top notch.

We didn't use an integrator or consultant. We handled the implementation ourselves.

We implemented it in-house.

Implement through vendor as special skills required.
