Docker is one of the fastest-growing technologies to emerge, not just in the past decade, but ever. This hot new containerization software has changed the game for how software will be built and delivered. And yet, it's still early days in terms of how containers will transform the way teams collaborate and businesses ship and support cloud software. In this talk, we will cover: * How DevOps and containers work together to enable better service delivery. * What the advent of microservices means for cloud users and providers. * What users and service providers require to cope with the changes wrought by containers.

1. Building with containers:

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

“ 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.”

36. What you need to do
• Yesterday: Develop a story around DevOps & containers
• Today: Begin to create support/services around DevOps
• Within 6 months: Support containers in compute, use internally elsewhere
• Within 18 months: Enable & encourage microservices migrations, consider
Lambda-style approaches & orchestration beyond them

37. The time for containers is now.
