This week on the podcast, Jeffrey Palermo is joined by Sudhanva Huruli, a Program Manager at Microsoft. He’s currently a maintainer on the Open Application Model and has been at Microsoft now for 2 years. In the past, he’s also worked on Microsoft's distributed systems platform (Service Fabric), led the effort for their Java developer offering, and helped design and build a product to provide visibility into the status of rollouts to any core Azure services.


In this episode, Jeffrey and Sudhanva explore the topic of the Open Application Model. Sudhanva explains what an OAM is, how it is different from a regular app, the major parts that make it up, the problems it solves, and what is on roadmap for the future of the OAM.
