 Hi everyone, I'm Abby Fry. I'm Head of Marketing and Communications at Moodle and today I have with me Marcus Samlensky. I've just listened to Marcus's very informative presentation on scalability really, taking 3,000 students to 1 million students in a school environment. So Marcus, can you tell us a little bit about the project? Sure. At the start of the pandemic we had gotten the mission to really create a system for where there was none. There were no Moodles, there were no e-learning systems at these schools. It was very basic, very frontal learning. And we were supposed to build a system that can host up to 7,000 schools. And therefore we built the system up so that we can scale school by school and eat school horizontally. So in the end we were able to achieve this, we were able to provision over 3,000 of these schools which host over 1.4 million students. Oh wow, I understand. That's incredible. That is in a huge volume. Heavy responsibility. You must have had some sleepless nights. Oh yeah, especially when the school year started and then there was a big peak, both in usage of the system and in new systems to be created because we created the system so that a principal of a school themselves can require such a system and have it built automatically in about half an hour. What technologies did you employ? Well, we had to heavily focus on automation but we did not use, let's say, very complicated technologies actually. We used classical VMs in a data center that we were able to acquire via API calls. So if a principal requests a school, a process starts which requests one of a new virtual machine via the API. This is then provisioned. Our automation tools then start, we are using Ansible for automation, then starts to provision these new virtual machines with Moodle with the data, with the database templates and all changes that need to be made to make the school, this Moodle machine custom for that school. So you think Moodle is well positioned for that? Oh yeah, Moodle is a very robust tool, very customizable via plugins, even if you're very good with Moodle and the technical side of Moodle, you can achieve even more than you can with the plugins just by building stuff yourself or applying templates and everything very well. Do you have a big team? My team is about seven people, so we do a lot with very little. Eladir itself is of course a bit bigger. Yeah, so Eladir is one of our premium certified partners in Germany and would you say that hosting and scalability is something you assist your customers, whether they're schools, universities or organizations? Is that something you regularly assist customers with? Yeah, all the time, whether they are coming to us to have systems built for a specific use case, let's say 25,000 users who do actually do quizzes or if it is on-premise hosting where we assist and do consulting, it's a very big issue. Yeah, a big part of the business. And I imagine when we have new releases or upgrades, does that pose challenges for you? How do you provision for that? Yeah, the challenges come often more with the plugins. Moodle itself is very easy to upgrade and maintain, I find. But of course, plugins and if we have custom plugins made for that customer, that of course needs to be checked if it works as a new version. That takes a bit more time. I can well imagine. And what systems do you have in place for support in the event of a problem? Well, of course, we do monitor all our systems. We do monitor the Moodle locks from Moodle itself for problems because of course, over the years, we found some things that are coming back again and again, especially if the user misconfigures the system or something. Other than that, we of course have a ticketing system where if they have anything they want for us to do, whether be it install new plugins or ask for help or for a special customization, they can send us an email and it creates a support ticket for us. Well, that's brilliant. Thank you so much, Marcus, for spending some time with me and enjoy the Moodle. Thank you.
