Show Notes

When you talk to the Temporal guys and look at the way that they've done some of their work is they have a... they have stuff that can run for years.

So for instance, they'll kick off a workflow for one of their customers, kicks off a workflow when the customer's created, and that workflow is like managed by Temporal for as long as that customer is a customer. So it could be, you know, I don't know, occasionally sending out an email to, you know, "happy birthday" or something, or sending them promotions or whatever. So they see, they see workflows as like lifetime things

— John Kattenhorn

Welcome to The Modern .NET Show! Formerly known as The .NET Core Podcast, we are the go-to podcast for all .NET developers worldwide and I am your host Jamie "GaProgMan" Taylor.

In this episode, John Kattenhorn joined us to talk about Temporal.io and their platform for building durable workflows which can operate for years at a time. John in the CEO of Applicita and wanted to talk about the ways that developers can build applications and workflows which can live in the cloud for a very long time.

And the great thing about Temporal is it manages all of those resources for you.

So if you imagined me and you trying to do that, we'd end up standing up, I don't know, a running service or something that was constantly polling the data, looking for eligible customers or something. You'd be burning some resources looking at that stuff, and that's not how they do that. So if you've got like a million customers, the Temporal system dehydrates everything that isn't relevant and only hydrates the workflows that have an action to perform

So let's sit back, open up a terminal, type in dotnet new podcast and we'll dive into the core of Modern .NET.
