And he previously worked on the developer experience team at red hat. Josef welcome to software engineering radio. [00:00:13] Josef: Uh, thanks for having me. I'm really happy to be here. There are a lot of commercial services for hosting applications these days. One that's been around for quite a while is Heroku, but there's also services like render and Netlify. why should a developer learn how to deploy from scratch and why would a developer choose to self host an application [00:00:37] Josef: I think that as a web engineers and backend engineers, we should know a little bit more how we run our own applications, that we write. but there is also a business case, right?For a lot of people, this could be, uh, saving money on hosting, especially with managed databases that can go, high in price very quickly. and for people like me, that apart from daily job have also some side project, some little project they want to, start and maybe turn into a successful startup, you know but it's at the beginning, so they don't want to spend too much money on it, you know?And, I can deploy and, serve my little projects from $5 virtual private servers in the cloud. So I think that's another reason to look into it. And business wise, if you are, let's say a bigger team and you have the money, of course you can afford all these services. But then what happened to me when I was leading a startup, we were at somewhere (?) and people are coming and asking us, we need to self host their application.We don't trust the cloud. And then if you want to prepare this environment for them to host your application, then you also need to know how to do it. Right? I understand completely get the point of not knowing it because already backend development can be huge.You know, you can learn so many different databases, languages, whatever, and learning also operations and servers. It can be overwhelming. I want to say you don't have to do it all at once. Just, you know, learn a little bit, uh, and you can improve as you go. Uh, you will not learn everything in a day. [00:02:28] Jeremy: So it sounds like the very first reason might be to just have a better understanding of, of how your applications are, are running. Because even if you are using a service, ultimately that is going to be running on a bare machine somewhere or run on a virtual machine somewhere. So it could be helpful maybe for just troubleshooting or a better understanding how your application works.And then there's what you were talking about with some companies want to self-host and, just the cost aspect. [00:03:03] Josef: Yeah. for me, really, the primary reason would be to understand it because, you know, when I was starting programming, oh, well, first of there was PHP and I, I used some shared hosting thing, just some SFTP. Right. And they would host it for me. It was fine. Then I switched to Ruby on Rails and at the time, uh, people were struggling with deploying it and I was asking myself, so, okay, so you ran rails s like for a server, right. It starts in development, but can you just do that on the server for, for your production? You know, can you just rails server and is that it, or is there more to it? Or when people were talking about, uh, Linux hardening, I was like, okay, but you know, your Linx distribut
