"One Day we May be Craftsman Again"

We live in a world where we are already expected to know, where competence is assumed, but competence disappeared with craftsmanship to be replaced by production lines.

"Phoenix Servers" - Martin Fowler on Resilient Infrastructure

It is a good idea to virtually burn down your servers at regular intervals. A server should be like a phoenix, regularly rising from the ashes. The primary advantage of using phoenix servers is to avoid configuration drift.

What Developers Think Of Operations

Development and Operations are both critical to IS/IT usage in an organization, but developers often look at operations as something alien – from another planet (and operations have the same view on developers). As we'll see, this couldn't be less true.

The Potential Problems of DevOps Culture

Culture is like quality. You don’t build culture, or quality, by talking about it. You build it by doing things, by acting, by making things happen and making things change, and reinforcing these actions patiently and continually over time.
