Matt Mitchell on DevOps on the .NET Core Engineering Services Team - Episode 63

Matt Mitchell is the lead engineer of the .NET Core Engineering Services Team at Microsoft. Matt joined Microsoft in 2006 after two years as an intern from 2004-05.

In today's episode, Jeffrey and Matt are taking a look into DevOps on the .NET Core Engineering Services Team! Matt dissects what Engineering Services is and what they're responsible for, some of the different system types within .NET Core, an overview of the .NET Core infrastructure and how they go about building and testing, and much more! Tune in to hear all of Matt's key insights around .NET Core and the Engineering Services Team.

[21:09] Matt provides an overview of the .NET Core infrastructure and how they go about building and testing.

[26:00] Architecturally, the MS build tasks are the way that individual teams are provided with the tools to call so they don't have to duplicate that logic in their build scripts. So, for YAML files, is it just template guidance but that logic is duplicated in each repository?

[32:20] Matt explains why choosing the right number of repositories is one of the biggest ways to absolve some difficulties.
