Elton Stoneman on Docker in a DevOps World — Episode 67

In today's episode, Elton Stoneman is joining the podcast! Elton is an Architect at Docker and an Azure MVP. He's currently in the process of writing his new book, Learn Docker in a Month of Lunches, which already has 9 chapters up online! It's a completely accessible, task-focused guide to Docker on Linux, Windows, or Mac Systems.   Elton started his career as a .NET Consultant and, as he says, 'Spent the last 10 years building big, ugly monolithic apps which [he] now spends his time teaching people how to break apart!' He soon became heavily interested in Docker and when the company had an opening for an Advocate, he reached out and joined their marketing team. After doing that for a couple of years, he became an Architect on their partnership team.   Docker has exploded in both popularity and usage. And since this is completely Elton's world, Jeffrey picks his brain in this episode to learn more about the design philosophy around it and the strategy behind it all!   Topics of Discussion: [:39] Be sure to visit AzureDevOps.Show for past episodes and show notes!

[20:20] Jeffrey poses a scenario to Elton: if your application is a Windows service and it's 10MB, how big is that Docker image going to be that is the release candidate? [22:06] How big should you expect the images to be if the application inside is 10MB? [25:30] How much uptake is Elton seeing on the Windows containers? [27:15] From an architectural strategy perspective, what does Elton and those at Docker think about when it makes more sense to use a Paz service versus a container? [31:04] In the future, does Elton foresee containers becoming the new normal to the extent of being baked right into the infrastructure of services in a way that most people won't even know that they're there?
