Simplifying Cloud Native Testing with Jón Eðvald

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...

ATO special episode with Peter Farkas

ATO special episode with Peter Farkas

In this special episode recorded at All Things Open, I talk with Peter Farkas, CEO and co-founder of FerretDB. We talked about about MongoDB and the license change fiasco and why Peter wanted to build an open source company and never considered building a non-open source company. The biggest 🤯 in this episode was about enforcing what it means to be open source; in particular, FerretDB positions itself as a truly open source alternative to MongoDB, and has received threatening letters from MongoDB as a result. How do you enforce it when a company claims to be open source but does not use an OSI-approved license? How well do the average users actually understand the license implications, and if a big company says they have an open source license even though it’s source-available, not open source, how much will people understand the difference? If you want another perspective on the enforcement of advertising around open source licenses, listen to the episode I recorded with Stefano Maffulli, also at All Things Open.

Selling Peace of Mind with Bhaskar from YottaDB

Selling Peace of Mind with Bhaskar from YottaDB

This week’s full-length episode is with Bhaskar, founder of YottaDB. This episode was recorded on-site at All Things Open last week, and we covered a wide range of topics. Including:How the open source ecosystem, and the open source business ecosystem, has changed over the past 30+ years.Who can responsibly self-support an open source database, and who really needs to have someone to call if things go wrong. The spectrum of professionalism among open source developers How YottaDB started out as a project developed inside a larger company that was in financial services; and Bhaskar decided to spin it out as it’s own company.The challenge articulating the value of support contracts, especially for software that is reliable. Bhaskar says he is selling peace of mind more than anything else; and he works with customers to avoid incidents — because ultimately avoiding an incident is a better outcome for everyone than a quick recovery from an incident. How to convince people that they are actually not as good at managing open source databases as they think they are. We also talked about conference strategies: according to Bhaskar, the way he’s decided which conferences to exhibit at is a series of trial and error — and by the way, this is something I’ve heard from many people. Yes, you have to think about where your customers are, not where your friends are, but sometimes you don’t know ahead of time which conferences are going to have the best ROI. I’m working with YottaDB right now on how to differentiate themselves in the crowded database market — and we talk about that process a bit right now. If you’re having trouble standing out in a crowded market, you might want to work with me.

ATO Special Episode with Tatiana Krupenya of DBeaver

ATO Special Episode with Tatiana Krupenya of DBeaver

This special episode of The Business of Open Source with Tatiana Krupenya, CEO of DBeaver, was recorded on site at All Things Open 2024. It’s a short conversation, so we addressed one main question: What is the difference between running an open source company versus as proprietary software company? Tatiana says the difference is big — and it’s complicated. The bottom line: Your OSS can be your main competitor, and your customers have to really see the value in your commercial offering if you want to make sales. ## If you aren't sure how to talk to your potential customers are about why they should use your commercial offering, you might want to work with me.

Behind the Scenes of the Open Source AI Definition with Stefano Maffulli

Behind the Scenes of the Open Source AI Definition with Stefano Maffulli

This week on The Business of Open Source, I spoke with Stefano Maffulli, Executive Director of the Open Source Initiative, about the definition of open source and… the definition of open source AI. We recorded this episode on-site at All Things Open, so there’s a little bit of background noise. We talked about why OSI felt like it needed to develop a definition of open source AI, how “open source” is enforced, and the thought process behind the definition that the OSI ultimately published. We talked about open data quite a bit — different kinds of data, what kind of information and data is important to researchers and professionals in the AI space, and if there’s a way to include AI models that are trained on proprietary data in the definition of open source AI. If you are interested in open source AI, definitely check out this behind-the-scenes discussion of how, and why, this definition was published — and what the future likely holds for defining open source AI.

Price Anchors of Zero Dollars with Anais Concepcion and Paul Fitzpatrick

Price Anchors of Zero Dollars with Anais Concepcion and Paul Fitzpatrick

This week on The Business of Open Source, I spoke with Anais Concepcion and Paul Fitzpatrick , the co-CEO of Grist Labs and CTO of Grist Labs. We talked about managing growth of users versus growth of revenue, moving to an open source approach for technical, not technical, reasons, and open-source related product management questions for open source companies. Some really interesting themes we talked about:Moving from a SaaS first approach to also focusing on enterprise sales. Why they did that, what other sales channels that opened and what questions it also forced the company to addressUser personas versus buyer personasThe situations in which Grist is the best option — which incidentally I could not understand from the website or the project documentationThe relationship between the open source project and both enterprise sales and SaaS sign-ups. How open source has been critical for a strategic relationship Grist has with the French government, which has been important for increasing product development velocityGiving up ‘darlings’ or features that they really want to develop but that they don’t think would drive revenueThe difference Anais sees between running Grist and running non-open-source companies — one of the most interesting differences is that users often have a sense of ownership over the project that you just wouldn’t see in a fully proprietary How open source true believers often work in large companies and control budgets, and should not be underestimated. Why trying to sell based on features — including telling yourself that if you just had one more feature, you’d unlock all the sales — was a big mistake. Are you struggling with price anchors fixed around zero dollars, or can’t figure out how to manage the push and pull of developing open source and building a business? You might want to work with me.

Getting people to use the features you already have with Eric Holscher

Getting people to use the features you already have with Eric Holscher

This week on The Business of Open Source, I spoke with Eric Holscher, co-founder of Read the Docs. We had a really far-ranging conversation that included talking about why documentation is often so bad, why documentation should be a priority, but also Eric’s experience building Read the Docs and Write the Docs. This episode was interesting because it’s both about building an open source company and also about the importance documentation for software projects in general and open source projects. Some things we covered included: What is documentation? Is it a marketing effort, is it a part of the project itself? Eric talks about how good documentation for an open source project is a clear signal of a level of seriousness for the project. How Read the Docs was really started to support open source projects, and that is part of why there’s no enterprise installs — either you use the open source code on your own, or you use the hosted product.How Eric sees building in the open as a way to help other people become better software engineers, but that ‘helping companies use Read the Docs for free’ is not the reason he wanted to build an open source company, and he’s still not sure how to feel about the fact that this happens. You don’t get bonus points for being open source or bonus points for being bootstrapped — it won’t prevent a potential customer from using a competitive product because it has a feature that Read the Docs doesn’t have. How open source in general — and even documentation in general — can help build brand value, but it is super hard to quantify and put in a slide in a board meeting to justify an investment in open source. The decision to build Read the Docs as a business stemmed from the pressure that Eric got from having a successful open source project. How they tried very hard to avoid accepting advertisements, but they should have started doing so much sooner because it turned out advertisements is well-aligned with the things they want to be working on. The difference in risk between being open source for a database company versus an app-level open source project like Read the Docs; for Read the Docs one of the risks is the brand damage associated with people running the OSS on-prem and doing a bad job. Are you the founder of an open source company and struggling with figuring out how to manage the relationship between the project and product? You might want to work with me. Enjoy the show? Help it reach more people by leaving a review and sharing with your friends.

Open source companies' reputation problem with Chris Holmes

Open source companies' reputation problem with Chris Holmes

Today on The Business of Open Source, I spoke with Chris Holmes, co-founder and CEO of Greymatter. Greymatter is deeply involved in the open source ecosystem and maintains the Go Envoy Control Plane, but Chris is adamant that it is not an open source company. We had a great discussion about why that is, what it means for the company and the conversations he ends up having around open source with his customers and partner companies. Some particularly interesting points that came up:Customers worry that buying Greymatter could force them to buy enterprise versions of open source software — and Chris thinks that this could be a symptom of the fact that many users expect that they’ll end up being forced to pay for something they don’t want to pay forHow open source companies, and open source projects in general, can be viewed as risky if they are only backed by one companyWho is gonna pay for open source? How if you are going to get away from open source projects being aggressively monetized, big companies have to put their money where their mouth is and pay for open source development directlyWhy and how to get started selling to governments. Yes, the sales cycles are longer but the deals tend to be very sticky once you get in — and why Chris actually finds it easier to sell to the military than to large enterprises. What benefits Greymatter gets from being a maintainer of the Go Envoy Control Plane. Struggling with how to get your product strategy right, and find the right balance between your open source project and your commercial offering? Not sure how your user audience and customer market relate to each other? You might want to work with me.

Building your product with your customers with David Höck

Building your product with your customers with David Höck

This week on the Business of Open Source, I spoke with David Höck, co-founder of Vendure. We talked about switching licenses from MIT to GPL, the ways that Vendure is different from it’s competitors and how architectural decisions can be a powerful differentiator for an open source company. Favorite quote: “You need to build your product together with your clients.” Some specifics we talked about that you should pay attention to: Why they switched to GPL in order to encourage more people to reach out to them and get more visibility into who was using their open source projectOn the other hand, they wanted to make sure that big companies building commercial platforms on top of Vendure’s platform are forced to pay for a commercial license. They also wanted to choose a less-permissive license, but something that was still well-known and wouldn’t cause a lot of confusion among users or potential customersThe difference between being happy with people using your software for free, and being happy with competitors using your software to build a competitive product, without offering any support to the underlying software. Do your customers care about whether you are VC-backed or bootstrapped? We had an interesting conversation about this, because Vendure is bootstrapped. I think we settled on a real important nugget — if your technology is really critical to the company, they will care about your long-term sustainability. Being bootstrapped can help convince potential customers that you are independent and will be sustainable for the long term. The top advantage of open source, David says, is the ability to get fast product feedback from a community. —> I just was talking with someone yesterday about this advantage of an open source strategy, I think it is under-discussed but extremely important. If you’re the founder of an open source company struggling with your product strategy — uncertain how to differentiate between project or product or how to differentiate the entire company in the ecosystem; don’t know what your project is supposed to do for your business; aren’t clear on the target market for your project or product — you might want to work with me.
