 Right, so we're moving on to the next talk. Lea, may I ask you on stage? So this is the result of a community survey, right? Done last year. Let me see if things are working. This is that's not the first line. No, but here's the clicker All right You have a mic. Yeah, you're good. And it's working as well. So hi everyone. My name is Lea I'm a PhD student right now at CISPA in sub rücken and I've been doing some work on Self-hosting because it's just interesting to me And I think it's also interesting to all of you So as we saw this morning next cloud is a very mature product already it has a broad set of applications and because it's open source it also caters to a broad variety of different users and When someone decides to self-host their services, they always have to put in this extra a little bit of work as opposed to relying on a third-party vendor to host the services for them and I've been actually asking myself like what's driving people to commit to this extra work and We had this community survey last year with Daphna together and I also talked to some Selected participants in one-on-one conversation and ask them about basically, you know What motivates them to self-host their services and also how they run their operations how they secure the operations and all different Kinds of roadblocks that they might run into so I talked to private users I talked to commercial users and I also talked to non-profit users and I'm giving you now a very crisp and broad Overview over some preliminary results. So in terms of motivation I think privacy It's like one of the like most promise prominent motivations for people Who are deciding to self-host? I think this is not really a surprise to anyone sitting here But what was actually surprising to me a little bit is that cost-saving also was of one driving factor And there were even people who said that this was like more or less the only reason why they're doing this like the privacy aspect Was at best secondary or they it was just not a reason for them at all Then you also have like this independence and control basically is contributing Factors that motivates people some people said that they are self-hosting because they want better security So they don't trust vendors And they want everything on their own hood and then you also have this educational aspect So people you know have this do-it-yourself mentality more or less and they just have fun doing it and you know just want to Educate themselves while trying to provide their own services If you take a look at like basically the landscape of technical setup, it's also very broad So some people are fine with giving away control like be it on the software side or also on the hardware side But that would be on the left-hand side here And then there are also some people who really want everything on their own belt So they want full control over both hardware and software and if you then factor in basically The tech expertise that people have it's again a broad spectrum So we have people that are actually Amateurs like all of them are somewhat a fine-to-technology But not everyone can be an expert and this is actually Data from the interviews that I got so the the blue hearts would be private users the squares are commercial people and the round-circles are non-profit users and I don't have time to go over everything because we all just have so a little time But like maybe one interesting thing is that expertise alone is not enough to basically predict what setup people will go for and It can even be an issue. So for example, if you consider on the bottom right You see that there are people that opt for like basically The maximum amount of hard and software control Although they might not be technically equipped to provide the service in that way and then they also run into issues So for example networking was a nightmare for a lot of people who don't have the expertise And then also they might not be or might not feel equipped to secure the services And they might not be confident confident in that basically so But they still decide to like for the maximum control because maybe they They cannot afford to go into hosting servers or also they want to be independent and have like full privacy basically so Some takeaways Like the self-hosting community is super broad It's even maybe more diverse than one might expect so it's diverse in the sets of them different motivational factors technical expertise Set ups are very diverse and because of that you also have different, you know security strategies that apply and then also in my understanding it's crucial to you know Get a sense of the distinct needs of the different user populations In order to help them run and secure their operations and In a good fashion. So this is actually naturally challenging for any sort of software product project But in my opinion next cloud because it's open source and because it has like a huge Active user base it also has like distinct opportunities because people are actually eager to contribute like it can also be a contribution for example to take part in such a study and This then can hopefully streamline Maybe ways to make it more accessible for for broader user space. Thank you Thanks Lea. All right, so
