Today’s episode is all about recognizing middle-of-the-day deployments; how teams such as Netflix, Facebook, and even the Azure DevOps Product Team are doing them; and taking a look at how other teams can achieve that for themselves!
Jeffrey Palermo’s guest today is Eric Fleming, a Software Architect at Clear Measure. Eric leads an intense team, developing and operating a mission-critical software system in the financial sector. He lives in Alpharetta, Georgia, and is a host of the Function Junction Youtube Channel, which is all about Azure functions. He’s also written articles for MSDN Magazine and CODE Magazine.
In this episode, Eric takes Jeffrey through his journey of inheriting a monolithic software system and the major transformations he had to execute to get it where it is today; deploying in the middle of the day! He explains the key steps he took in breaking up the monolith, the development process, who was involved, what the structure and DevOps environments looked like, and all of the details you need to know if you’re finding yourself in a similar situation!
