News

A look at lock-in, specifically describing a difference between operational lock-in and developer lock-in, and how and why they might affect different organisation differently.

A good blog post on why it’s important to apply continuous delivery principles to infrastructure as well as applications. Constant change is the only way to avoid the fear of change setting in.

I’m not sold on the term Deep Container Inspection, but this is a solid post on some of the challenges of containers today and how we might solve them using metadata and vulnerability scans as part of our build pipelines.

Some ideas for different types of devops roles, as well as the concept of a Devops office, similar to a Project management office. Some good discussion in the comments too.

An interesting look at different team topologies that organisations are using when embracing devops practices. It will be interesting to see which of these solidify and which turn out to be transitory.

Interesting notes (and a full recording) from a session at ContainerCon about the relationship between containers and unikernels.

A look at Azure Resource Manager Templates, which provide a way of describing an entire stack in code and launching it in Azure at the click of a button. The example shown builds a fully working Docker Swarm cluster.

Tools

The problem of building Docker containers is definitely ripe for new tools to emerge, and dockramp looks interesting - it extends the Dockerfile syntax, makes smarter decisions about the creation of layers and aims to be faster than the standard docker build command.

Many infrastructures will use an SSH jump box or two, rather than exposing all machines directly. SSHmuxd is an application which aims to make this easier to manage, at the same time as introducing some basic access control features.

An interesting take on testing Puppet code, Puppet Spec uses the Puppet language to write tests for Puppet by adding a new assertion type to the language.

Cloudsploit Scans is an interesting set of checks for scanning your AWS setup for potential security issues.
