Docker: Git for deployment
Docker is to deployment as Git is to development.

Developers are able to leverage Git's performance and flexibility when building applications. Git encourages experiments and doesn't punish you when things go wrong: start your experiments in a branch, if things fall down, just git rebase or git reset. It's easy to start a branch and fast to push it.

Docker encourages experimentation for operations. Containers start quickly. Building images is a snap. Using another images as a base image is easy. Deploying whole images is fast, and last but not least, it's not painful to rollback.

Fast + flexible = deployments are about to become a lot more enjoyable.

Vagrant and Chef to provision dev test environments
We have recently switched from a manually configured development environment to a nearly fully automated one using Vagrant, Chef, and a few other tools. With this transition, we’ve moved to an environment where data on the dev boxes is considered disposable and only what’s checked into the SCM is “real”. This is where we’ve always wanted to be, but without the ability to easily rebuild the dev environment from scratch, it’s hard to internalize this behavior pattern.

OmniTI's Experiences Adopting Chef
A good, in-depth writeup of OmniTI's best practices with respect to build-out of multiple customer deployments, using multi-tenant Chef from a version-controlled repo. Good suggestions, and I am really looking forward to this bit:

'Chef tries to turn your system configuration into code. That means you now inherit all the woes of software engineering: making changes in a coordinated manner and ensuring that changes integrate well are now an even greater concern. In part three of this series, we’ll look at applying software quality assurance and release management practices to Chef cookbooks and roles.'
