Docker enables agile_devops

Docker enables new agile practices by allowing developers to work in environments that closely match production. However, DevOps thought leaders must determine how Docker adoption fits with their organization's culture and ensure it leads to business benefits like increased velocity without disrupting existing processes and tools. While Docker shows promise for accelerating development and operations, its impact on an organization depends on how well leaders apply agile and DevOps principles during implementation.

Developers can take risks such as
upgrading PHP knowing they can get
back to a working state in seconds
instead of days. Enabling innovation
means better velocity.

The Dockerfile (code) that describes the
run time environment is what ensures
a working environment, not a huge
wiki that is chronically out of date.

A developer can change the function of a

customer (B2B) asking, "like this?”
Developers can kick out new features that can

At the bleeding edge, collaboration across
function becomes about producing tests
rather than processes for inhibiting
innovation. Code becomes the documentation
and collaboration happens at the engineering
level rather than the process control level.

On the bleeding edge change becomes about how to
ensure behavior of software rather than people.
Software problems are easier than people problems.
I believe the manifesto needs an update here to value
the _quality_ of interaction.

Micro teams move at their own pace. The

There is little inter-team communication

At Pantheon, for example, this is a crucial
point. Customers use the fully featured system
indefinitely for free. They purchase value

Ops, in terms of DevOps thinking, is about eliminating

An argument can be made that Docker allows for
automated response to change (scaling and disasters
