It’s another big week for DevOps stories — here’s some of the things that I found interesting:

Hello, Pulumi Joe Duffy announces Pulumi, a new cloud development platform that lets you write code — real code, not YAML — to compose and create cloud infrastructure. We’re excited to take this for a spin and see how we can use Pulumi to build Azure infrastructure on-the-fly and deploy to it from VSTS.

Supercharging the Git Commit Graph What happens when you take a graph theorist out of academia and put him to work on Git? He makes some incredible performance improvements. Derrick Stolee from the VSTS team explains how he improved the speed of Git’s graph traversal — first in Visual Studio Team Services and then in Git itself.

How Software Developers Can Use Science to Manage Their Time We’re all about developing faster and deploying faster so that we can bring new features to our users as quickly as possible. But how do you measure your productivity, and how do you plan your time? Our friends at 7pace wrote this great article about how you can use science to manage your time.

The DevOps Lab: DevOps for Data Science Damian Brady sits down with Paige Bailey and Terry McCann to discuss how DevOps can enable Data Science. They explore what’s important to data scientists and where to start when it comes to a DevOps process; from using source control, testing and refreshing predictive models to operationalizing and evaluating success in production.

Making Docker Compose Easier to Use with Application Packages Docker Compose is wildly popular with developers for describing an application — but it also has a lot of features that are focused on the deployment of those applications to production. What if you could simplify application packages, to make it easier to share and collaborate? Now you can — Docker’s introducing an experimental tool called docker-app that helps make compose-based applications.

New Navigation for Visual Studio Team Services If you think that the UI and UX of Visual Studio Team Services is starting to feel a bit dated, then we’ve got some great news for you. The new VSTS interface has a gorgeous, Fluent-inspired design with modernized navigation experiences. The new VSTS is clear, concise and — best of all — fast.
