In this talk, Donnie shared what he's seen and what he predicts for the future of how we build and deploy applications to generate business value. You'll hear buzzwords like DevOps, Docker, and microservices used in ways that actually make sense (for a change), see real-world examples of companies that have succeeded at the leading edge, and learn how approaches like the one taken by HashiCorp's Terraform (by the authors of Vagrant) will be critical to the future of how we build software.

We are early adopters on the leading edge
We are pragmatic about new technology, but
will act sooner rather than later
We are conservative about new technology
and take a wait and see approach
We are skeptical and are usually late to the

29. Fragmentation
drives microservices —
enabled by containers

Loosely coupled services

31. Loosely coupled teams
“ One of the biggest changes is that we no longer have
an official ‘architecture’ team. Instead, we have made
‘architecture’ an ‘ingredient’ on each of our teams.”
