Transcript

Michael Lynn: Welcome to the show. My name is Michael Lynn and this is the MongoDB Podcast. Thanks for joining us. Today on the show, Lena Smart, Chief Security Officer of MongoDB, and I team up to interview Dwight Merriman, co- founder and key contributor to MongoDB. Dwight Merriman is a true tech legend. In addition to co- founding and co- creating the MongoDB database and 10gen now called MongoDB, the company. He also co- founded and led several other well known successful companies including Business Insider, DoubleClick and Gilt Groupe. In today's interview, Dwight shares openly and honestly about the motivations behind creating the database, which now actually claims nearly half of the entire NoSQL market. He talks about the decision to build the database rather than use something that existed at the time. Dwight's friendly, easy to talk to, knowledgeable, and probably one of the smartest individuals that I've had the pleasure of chatting with. Without further ado, let's get to the interview.

Hey, did you know that MongoDB University has been completely redesigned? That's right. Hands- on labs, quizzes, study guides and materials, bite- sized video lectures, programming language specific courses. You can learn MongoDB in the programming language of your choice, Node. js, Python, C#, Java, so many more. You can earn that MongoDB certification by validating your skills and leveling up your career. Visit learn. mongodb. com today.

Lena Smart: So it is my absolute pleasure, and I'm so glad that you could make it in person today, to introduce Dwight Merriman. He is the first CEO of MongoDB, and you were still coding, I understand. You're also co- founder and director of MongoDB as of today. Are you still coding?

Dwight Merriman: I'm still coding or tinkering a bit myself, but not on the database anymore. I think there's, to really dive in and work on it, there's a certain minimum number of hours a week you have to work on it, just to keep up with the code base and the state of everything, because it's not short, it's not a small program anymore.

Lena Smart: Amazing. And also in the room we have Mike Lynn, who's our developer advocate, and I know that you'll likely have some questions.

Michael Lynn: Yeah, for sure.

Lena Smart: And just fire ahead, because probably this will be the most interesting person I'll speak to in a inaudible too.

Michael Lynn: Well I'm fascinated already and I've got so many questions for Dwight, but I'm going to let you go ahead and ask away.

Lena Smart: Cool. So the first question I have, and this has been a burning question of mine since I joined three and a half years ago, is how did you start the company? How did you start MongoDB?

Dwight Merriman: Right, so when we started, actually the name of the company was 10gen, and this was around 2008, or I forget the date, maybe two months before that, I can't remember. The original, what we were really looking at, at the time, is as myself and our other co- founders like Elliot and Kevin, we've been working on various entrepreneurial projects, and we were seeing this repeated pattern where over and over. New product idea, you start building the system. At this point, I've been doing that for quite a long time. So knew what the best practices were at the time. But it was always around that timeframe, January, 2008, whenever it was, it just seemed like it was always a bit awkward. There was awkward and un- anesthetic, and it just seemed like there was a lot of duct tape and rubber bands. And even though those were best practices. You would talk to CTOs at the time, and they would say things like, " Putting memcached in front of databases is okay, and roll your own sharding in front of my MySQL sequel or Postgres is okay, but it isn't. It was because there wasn't a better way at the time. And everything, that was really when the cloud computing EC2 was really taking off. So it was very clear to us that cloud computing was the future, and a lot of the traditional products weren't very cloud- friendly. So if you have a database that scales vertically, so I can make it bigger, but then it's a mainframe, or a Sun 6500 or something like that, that's the opposite of a cloud principle, which is horizontal scalability and elasticity. And then if you tried to do it the other way, horizontally, it was usually rolling your own when it came to operational databases. And a lot of other things, but also just agile development was the way to go then, all iterative development. But a lot of the old tools, and this isn't just databases, but languages, everything, weren't really designed for that, because they were invented earlier. So it's not their fault. So we were just saying, " Gee, there's got to be a better way to develop applications," and this is both on the how to develop them, how to code them, and also on how to scale them, and how to run them in the cloud painlessly. So our first concept was just we were going to do platform as a service. So we were going to try to do a fresh take on the developer stack, versus LAMP and whatever else was common then. And see what we could come up with. So we started building a platform as a service system. It was open source and this was very early. So I think when we went to beta, it was almost exactly the same time that Google's, was it Google App Engine?

Lena Smart: Yeah.

Dwight Merriman: It's the same time it came out to beta. So our timing was, it was like when they came out with it. And I was like, "Oh, okay, somebody there's thinking similar thoughts." And so that was fine. But a few months later, as we got a little further into it, I was thinking about it and I was like, I'm looking at things like AWS, where they have all these microservices. And they're like, " I'm not going to give you a full cloud platform. I'm going to give you some building box for your toolbox, and over time I'll give you more." Because the scope is large, so today they have a lot of services, but this, we're 15 years later- ish. So if I give you a platform though, to give you everything you need really, it's a big scope, and it's going to take quite a while to build it. So I think platform as a service makes sense, but we got further into it, and we had something working analogous to Google App Engine, or I guess, Heroku was around back then. It just felt like, " Boy, to get this true maturity, there's so many pieces that you would want in it. It's going to take a long time. This is, it's going to take a decade or something." And for a startup you only have so much runway. And it's now even today platform as a service, I think, is a valid notion and concept, but it's certainly not mature yet. The more AWS style or microservices- style approach, which you could do on all the big cloud platforms today, I just, I say AWS because I'm just contrasting it with the PaaS vendors back in the day, approach is still the dominant approach. So we've been building this, and really what were we building? So we're trying to build something where you'd write some code, you put it in inaudible, then you would just click Deploy. And it would deploy your app into our system in the cloud, try to handle scaling for you, including things like app server layer, app tier, how many app servers should there be, and low balancing for that....
