Simplifying Cloud Native Testing with Jón Eðvald

The conversation covers:

• Some of the pain points and driving factors that led Jón and his partners to launch Garden. Jon also talks about his early engineering experiences prior to Garden.
• How the developer experience can impact the overall productivity of a company, and   why companies should try and optimize it.
• Kubernetes shortcomings, and the challenges that developers often face when working with it. Jón also talks about the Kubernetes skills gap, and how Garden helps to close that gap. 
• Business stakeholder perception regarding Kuberentes challenges. 
• The challenge of deploying a single service on Kubernetes in a secure manner — and why Jón was surprised by this process. 
• How the Kubernetes ecosystem has grown, and the benefits of working with a large community of people who are committed to improving it. 
• Jón’s multi-faceted role as CEO of Garden, and what his day typically entails as a developer, producer, and liaison. 
• Garden’s main mission, which involves streamlining end-to-end application testing.

Transcript:

Emily: Hi everyone. I’m Emily Omier, your host, and my day job is helping companies position themselves in the cloud-native ecosystem so that their product’s value is obvious to end-users. I started this podcast because organizations embark on the cloud naive journey for business reasons, but in general, the industry doesn’t talk about them. Instead, we talk a lot about technical reasons. I’m hoping that with this podcast, we focus more on the business goals and business motivations that lead organizations to adopt cloud-native and Kubernetes. I hope you’ll join me.

Emily: Welcome to The Business of Cloud Native. I'm your host Emily Omier. And today I'm chatting with Jón Eðvald. And, Jón, thank you so much for joining me.

Jón: Thank you so much for having me. You got the name pretty spot on. Kudos.

Emily: Woohoo, I try. So, if you could actually just start by introducing yourself and where you work in Garden, that would be great.

Jón: Sure. So, yeah, my name is Jón, one of the founders, and I’m the CEO of Garden. I've been doing software engineering for more years than I'd like to count, but Garden is my second startup. Previous company was some years ago; dropped out of Uni to start what became a natural language processing company. So, different sort of thing than what I'm doing now. 

But it's actually interesting just to scan through the history of how we used to do things compared to today. We ran servers out of basically a cupboard with a fan in it, back in the day, and now, things are done somewhat differently. So, yeah, I moved to Berlin, it's about four years ago now, met my current co-founders. We all shared a passion and, I guess to some degree, frustrations about the general developer experience around, I guess, distributed systems in general. And now it's become a lot about Kubernetes these days in the cloud-native world, but we are interested in addressing common developer headaches regarding all things microservices. 

Testing, in particular, has become a big part of our focus. Garden itself is an open-source product that aims to ease the developer experience around Kubernetes, again, with an emphasis on testing. When we started it, there wasn't a lot of these types of tools around, or they were pretty early on. Now there's a whole bunch of them, so we're trying to fit into this broad ecosystem. Happy to expand on that journey. But yeah, that's roughly—that's what Garden is, and that’s… yeah, a few hop-skips of my history as well.

Emily: So, tell me a little bit more about the frustration that led you to start Garden. What were you doing, and what were you having trouble doing, basically?

Jón: So, when I first moved to Berlin, it was to work for a company called Clue. They make a popular period tracking app. So, initially, I was meant to focus on the data science and data engineering side of things, but it became apparent that there was a lot of need for people on the engineering side as well. So, I gravitated into that and ended up managing the engineering team there. And it was a small operation. We had more than a million daily active users yet just a single back end developer, so it was bursting at the seams. 

And at the time running a simple Node.js backend on Heroku, single Postgres database, pretty simple. And I took that through—first, we adopted containers and moved into Docker Cloud. Then Docker Cloud disappeared, or was terminated without—we had to discover that by ourselves. And then Kubernetes was manifesting as the de facto way to do these things. So, we went through that transition, and I was kind of surprised. It was easy enough to get going and get to a functional level with Kubernetes and get everything running and working. The frustration came more from just the general developer experience and developer productivity side. Specifically, we found it very difficult to test the whole application because we had, by the end of that journey, a few different services doing different things. And for just the time you make a simple change to your code to it actually having been built, deployed, and ultimately tested was a rather tedious experience. And I found myself building tools, bespoke tools to be able to deal with that, and that ended up being sort of a janky prototype of what Garden is today. And I realized that my passion was getting the better of me, and we wanted to start a company to try and do better.

Emily: Why do you think developer experience matters?

Jón: Beyond just the, kind of, psychological effect of having to have these long and tedious feedback loops—just as a developer myself, it kind of grinds and reduces the overall joy of working on something. But in more concrete material terms, it really limits your productivity. You basically, you take—if your feedback loop is 10 times longer than it should be, that exponentially reduces the overall output of you as an individual or your team. So, it has a pretty significant impact on just the overall productivity of a company.

Emily: And, in fact, it seems like a lot of companies move to Kubernetes or adopt distributed systems, cloud-native in general, precisely to get the speed.

Jón: And, yeah, that makes sense. I think it's easy to underestimate all the, what are often called these day-two problems, when—so, it's easy enough to grok how you might adopt Kubernetes. You might get the application working, and you even get to production fairly quickly, and then you find that you've left a lot of problems unsolved, that Kubernetes by itself doesn't really address for you. And it's often conflated by the fact that you may be actually adopting multiple things at the same time. You may be not only transitioning to Kubernetes from something analogous, you may be going from simpler, bespoke processes, or you might have just a monolith that didn't really have any complicated requirements when it comes to dev tooling and dev setups. So, yeah, you might be adopting microservices, containers, and Kuberne...
