Developing, using, and re-using Free Software is fun, but dealing with licensing and copyright information is not. REUSE changes that. With three simple steps, it makes adding and reading licensing and copyright information easy for both humans and machines. In this presentation, Lina Ceballos will guide us through the REUSE principles and will show us how to make licensing clear and simple. If you want to grant users the freedoms to use, study, share and improve your software, you have to grant those freedoms in the software licence. To encourage people to develop Free Software, we help developers to understand and apply Free Software licences. Since 2017, REUSE contributes to this goal. Any project that follows the initiative's recommendations makes copyright and licensing information readable for both humans and machines. In this way, we want to ensure that individuals, organisations and companies that are reusing code are aware of the licence terms chosen by the original author. REUSE does not "reinvent the wheel". On the contrary, it integrates seamlessly into development processes and other best practices when indicating Free Software licences. In addition, there are tools and documentation to help you get started. During this talk we will take a closer look at these tools and documentation, with the bonus of seeing a live demonstration of how to make a project compliant with the REUSE specifications. about this event: https://programm.froscon.org/2022/events/2756.html

Mapping is time-consuming and requires a high workforce when it comes to keeping maps up-to-date. Mapillary brings a different approach to geospatial data collection with street-level imagery. This approach allows communities to collect geospatial data faster and cheaper. But can Mapillary-generated data be useful for enriching OpenStreetMap? In this study, Mapillary-extracted map data will be examined against ground truth to assess data quality on contributing to OpenStreetMap. In this case study the positional accuracy and completeness are assessed by benchmarking Mapillary-generated data against ground truth for street light provided by Ordu Metropolitan Municipality in the borough of Altinordu, which covers an area of 9 km2. A total number of 323 street lights were recorded in the authoritative dataset. Completeness and positional accuracies are evaluated for each street light for different camera setups. In order to compare the impact of camera type on positional accuracy, street-level imagery was collected with three different cameras: iPhone 11, GoPro Hero 7 Black and GoPro Max. Collected street-level imagery was uploaded to Mapillary by using the Desktop Uploader. Imagery which are captured from different cameras is isolated during the upload to compare map data accuracy, completeness and correctness comparison based on camera type. In this experiment, we validate the effectiveness of Mapillary extracted map data by focusing on streetlights by evaluation results based on completeness and positional accuracy key performance indicators. The best result of completeness is achieved with GoPro Hero 7 Black with 87.57% in the working area and it is followed by GoPro MAX with 77.30% for Mapillary extracted street light data . Lastly, the completeness of iPhone 11 acquired data is 71.89%. In terms of positional accuracy, our experiment shows GoPro MAX captured street-level imagery can be extracted with 2.02 m of positional error and it is followed by GoPro Hero 7 Black with 2.17 m of positional error. The average positional error of street light which is extracted from iPhone 11 captured street-level imagery is 2.21 m. This positional error is close to the precision of a single frequency GPS receiver. This experimental study shows that positioning accuracy is highly related to the GPS accuracy of the capture device, and in general, a large part of the final positional error can be attributed to this. Mapillary's 3D reconstruction is able to mitigate some of these effects. Additionally, capturing with a large field of view has a positive effect on accuracy. In this study we also validate that positional accuracy depends on various factors of the capture process; precision of GPS receiver and additionally positioning hardware, resolution and quality of the images, image capture frequency of the camera, imagery density in the working area and type of photo such as flat or 360. The overall positional accuracies are under 5m which can be a promising solution for enriching street lights data on OpenStreetMap and collecting streetlights inventory for the municipalities and governmental bodies if this data will not be used for surveying purposes or reference data, however Mapillary-generated data can be useful and time effective as complementary data with low cost collection expenses. about this event: https://2022.stateofthemap.org/sessions/DKLT7X/

What if provisioning a server was easy? No dependencies, declarative way, early-boot and no half-state provisioned instance? Let's dive into Ignition, a one-time provisioning software. In this talk, we'll cover an overview of Ignition, an open-source software developed by Fedora CoreOS and used by a couple of Linux distribution (mainly cloud oriented like Flatcar). Illustrated with configuration examples, we will start from the execution in the initramfs to a fully booted and provisioned system. Finally, we will have a look to Ignition config generation and how it's possible to contribute to the software. about this event: https://programm.froscon.org/2022/events/2776.html

Dieser Vortrag beleuchtet die Anforderungen der Datenschutzgrundverordnung an die Betreiber:innen von webbasierten Diensten. Menschen die eine Instanz von <em>was auch immer</em> für <em>wen auch immer</em> aufsetzen, erfahren, worauf sie achten müssen und welche Handlungsschritte noch notwendig sind, wenn das eigentliche Setup schon steht und so eigentlich produktiv gehen könnte. Entwickler:innen erfahren, wie sie ihre Software so bauen können, dass sie möglichst einfach DSGVO-konform einsetzbar wird. Freie Software wird in aller Regel als besonders datenschutzfreundlich beschrieben. Sie ist per Definition transparent und ermöglicht ein hohes Maß an Kontrolle. Die Abwesenheit von datengetriebenen Geschäftsmodellen führt zu Implementierungen, bei denen Datensparsamkeit eher die Regel als die Ausnahme ist. Optimale Voraussetzungen also, um datenschutzkonforme Alternativen zu den proprietären Cloud-Diensten zu schaffen. Aber leider reicht der DSGVO das nicht. Um zu verstehen was die Datenschutzgrundverordnung von uns will, müssen wir die dort verankerten Rollenkonzepte entwirren. Als Betreiber:in einer webbasierten Anwendung wird man zum „Verantwortlichen“ oder zum „Auftragsverarbeiter“ – je nachdem für wen man das Ganze betreibt. Und Datenschutz macht man nie für sich selbst, sondern die „Betroffenen“. Das können aktive User sein, aber auch die vermeintlich anonymen Besucher, die nur bis zur Login-Maske kommen. Weil Internet=IP. Und IP-Adressen sind per Definition personenbezogen. Sagt jedenfalls die DSGVO. Daher kommt man im Fall von webbasierten Anwendungen nicht um formellen Datenschutz à la DSGVO herum und übernimmt in einer der beiden Rollen Verantwortung dafür, was die Software die man da betreibt so tut. Neben den üblichen Anforderungen aus dem Bereich der IT-Sicherheit muss man ein hohes Maß an Transparenz herstellen und sich Gedanken machen, warum man welche Daten hat. Und falls mal jemand mehr wissen will, muss man auch genauer nachschauen können und im Zweifel für die Person im eigenen System etwas aufräumen. about this event: https://programm.froscon.org/2022/events/2769.html

Cockpit is an easy to use web-based interface for your servers which relies on a lot of external dependencies for it's functionality. This talk describes how Cockpit is tested, tests are run on multiple distributions and issues reported upstream. Cockpit is an easy to use web-based interface for your servers and is supported & tested on Debian, Ubuntu, RHEL, CentOS, Fedora and Arch Linux. Cockpit depends on a lot of external dependencies for it's features such as managing networking, firewall rules, users, containers, virtual machines and services. To make sure a new feature works well and keeps working on all supported distributions Cockpit has an elaborate custom testing CI setup. All issues found during testing are reported upstream and automatically detected when a new version fixes the issue by our CI. This talk explains how we run our tests on multiple distributions, write tests so they work on all distributions and constantly test new releases and updates of distributions. Also included is how our npm dependencies are tested and how we make sure to not introduce UX regressions by having pixel tests, in general this talk discusses the whole CI architecture of Cockpit, how we keep our CI under control from running too long and report and track issues upstream. about this event: https://programm.froscon.org/2022/events/2779.html

opsi ist ein heterogenes OpenSource Client-Management-System. Dieser Vortrag gibt einen Einblick in die Testinfrastruktur, die mit den Jahren aufgebaut wurde, um die Entwicklung und die Releases vom opsi-Projekt zu unterstützen. Das reicht von Codetests bis zu End-To-End-Tests. Dabei wird ein Einblick gegeben, welche Technologien eingesetzt werden und wie die Test-Strategie umgesetzt wurde. CI First hat sich als goldene Regel etabliert. Aber was bedeutet das und vor allem warum ist das wichtig? Auch diese Fragen werden im Vortrag beantwortet. about this event: https://programm.froscon.org/2022/events/2795.html

OpenStreetMap Foundation Board Ask Us Anything (i.e. AMA). We will take questions from the audience, or other questions that people can submit before the event, and we will talk about and answer them. We can talk about the past actions of the board, and what future plans we have. This is a chance to ask the OSM Foundation Board questions, to engage with the board. Let’s have a conversation about the Foundation, the Board and how all the parts work together. If you know nothing about what the board is doing, this is a chance to find out. Find out what the Foundation does and doesn’t do, what it can and can’t do. Find out how you can help, how you can get involved. The Board is committed to openness and wants to engage with the community. about this event: https://2022.stateofthemap.org/sessions/AT3YM7/

The Amazon Forest, its traditional peoples, and riverside communities represent an immense challenge for official cartography, due to scale and extension factors. This presentation aims to show the experiences of the Unificar Ações e Informações Geoespaciais (UAIGeo) chapter of the Brazilian YouthMappers in mapping riverside communities in the Amazon rainforest region, focusing on the city of Tefé and its islands. Due to its female leadership role and the goals of empowering young women in geospatial and technical skills, the presentation emphasizes the importance of engaging and encouraging female students to link mapping and female empowerment. In Brazil, it is still an immense challenge to produce official cartography on the regional and local scale due to the extension of the territory, the number of municipalities (5,568 plus the Federal District), and the expensive cost of producing the mapping. Such factors are more significant in the Northern Region of the Country, where an important part of the Brazilian Amazon Forest and many traditional peoples and riverside communities are located. Many of the riverside communities do not have records in documents about their ancestral knowledge, cultures, territories, etc. Their knowledge and stories are transmitted orally and, despite the importance of this legitimate source of data, an important amount of information can be lost over time [1] The distances between riverside communities, in addition to the small geographic space the built infrastructure occupies, make them invisible in many official mapping. The riverside buildings are not visible in official mappings and have cultivated areas between 0,2 to 3 hectares. In this context, collaborative mapping through open data platforms is one cheaper possibility to mitigate the lack of maps in Brazilian municipalities. The OpenStreetMap (OSM) platform emerges as promising because it has wide territorial coverage of high-resolution images, which makes it possible to view the communities on the local cartographic scale. This presentation has the aim to show the experiences of the Brazilian YouthMappers’ chapter Unificar Ações e Informações Geoespaciais (UAIGeo), in partner with Centro de Estudos Superiores de Tefé-Universidade do Estado do Amazonas - CEST/UEA, within mapping riverside communities in the Amazon rainforest. In its initial phase, the project received support from the Everywhere She Maps program, due to its women leadership role and goals of empowering young women in geospatial and technical skills. Globally, on average 35% of female students entering the university choose fields in science, technology, engineering, and math - STEM [2]. The Global Gender Gap Report 2020 shows that Brazilian women represent just 18% of employees in technological jobs, a percentage below the global average [3]. Additionally, according to a study that has analyzed OSM users and the manifested gender, by 2019 female participation reached 13% [4]. For this reason, this presentation emphasizes how important it is to engage and incentivize women’s participation both from external and local communities. Gender relations are important components of key forest-related issues, such as climate change and the differences in opportunities facing women in these contexts. However, there is little literature on forest and gender in Latin America, particularly in the Amazon Forest [5] The chapter have been coordinating a series of mapping activities focused on the municipality of Tefé and verified that volunteers have mapped so far 11.082 buildings in the Humanitarian OpenStreetMap Tasking Manager platform since last year. Together with local collaborators from CEST/UEA, chapter members validated some names of communities on one of Tefé’s islands. Chapter members carried out fieldwork in Tefé to know the local reality and some places that they had mapped. They also conducted studies in São Luís do Macari, a community that is located on an island in the middle of the Solimões River. Results of remote and fieldwork activities will be presented while at the same time emphasizing the importance of engaging and encouraging female students to link mapping and female empowerment. * [1] De Magalhães Lima, D.; Ferreira Alencar, E.

Der Vortrag erklär anhand von Beispielen aus den Berichten der Beauftragten für den Datenschutz, welche Fehler bei der Programmierung und Anwendung von Software gemacht und durch die Datenschutzbehörden beanstandet wurden. Im Anwendungabereich der Datenschutzgrundverordnung sind durch die Verantwortlichen die datenschutzrechtlichen Grundsätze einzuhalten. Der Vortrag erklärt, warum es die datenschutzrechtlichen Grundsätze gibt und zeigt exemplarisch anhand von Beispielen aus den Datenschutzberichten der (Landes-) Beauftragten für den Datenschutz (und die Infromationsfreiheit) welche Fehler bei der Programmierung und Anwendung von Software gemacht und durch die Datenschutzbehörden beanstandet wurden. Die Nichtberücksichtigung der datenschutzrechtlichen Vorgaben stellt für den Softwareentwickler unter Umständen auch ein rechtliches Risiko trotz weitestgehendem Haftungsausschluss durch FOSS-Lizenzen dar. Wann dies der Fall ist, wird abschließend kurz erläutert. about this event: https://programm.froscon.org/2022/events/2794.html

Pull requests sind ein Weg, den Software-Entwicklungsprozess zu organiseren und robuster zu gestalten. Sie sind besonders nützlich bei lokal und zeitlich verteilter Zusammenarbeit, in globalen Open Source-Projekten wie auch in kleineren Unternehmen. Aber was macht gute Pull Requests aus? Gutes Reviews? Und wie können wir den Weg für beide ebnen? Malte erzählt, was er von Open Source-Projekten zum Umgang mit Pull Requests gelernt hat, welche Synergien sich in seinem Entwicklungsprozess ergeben haben und gibt ein paar weitere Ideen zur Einrichtung der Umgebung, zum Schreiben, zum Reviewen und zum Mergen von Pull Requests. about this event: https://programm.froscon.org/2022/events/2728.html

Kann es nicht vorteilhaft sein sich mit anderen Open Source Projekten oder sogar mit Unternehmen zu vernetzen und sich auszutauschen? Das wird jetzt zwischen Linux-Distributionen und IBM beim Open Mainframe Project praktiziert. Daneben gibt es viele weitere Möglichkeiten sich auch als Unternehmen in Open Source Projekten einzubringen. Das wird hier im Vortrag mit integriert. Open-Source-Projekte – besonders Linux-Distributionen – zeichnen sich durch die Zusammenarbeit in Upstream-Projekten aus. Auch für Unternehmen kann es von Vorteil sein, zu Open-Source-Projekten beizutragen. Man baut seine Partnerschaften aus, arbeitet über Communities mit anderen Unternehmen zusammen und kann so auch etwas für die Kunden tun. Aber ist es auch möglich, dass mehrere Linux-Distributionen sich für die Zusammenarbeit mit Unternehmen in Arbeitsgruppen organisieren? Das wurde von openSUSE, Fedora und Debian für eine bessere Zusammenarbeit mit IBM über das Open Mainframe Project als Beispiel organisiert. In diesem Vortrag geht es um die Vorteile für Unternehmen zur Zusammenarbeit mit Open Source Communities wie auch die Möglichkeiten und Vorteile der Zusammenarbeit zwischen Open-Source-Projekten. about this event: https://programm.froscon.org/2022/events/2799.html

The Ahrtal flood disaster and a war in Europe will obviously increase requirements on geo-redundancy. OpenSource via MARS can help. Experiences from 1&1 IONOS datacenters running millions of customers and petabytes of data will inform you on current state and on future trends. This talk will discuss more possibilties for datacenters, how geo-redundancy can be built and operated, and in long term. The Linux kernel module MARS is now replicating more than 10 petabytes over long distances, running on thousands of servers. A future version shall be able to replace iSCSI inside of any geo-redundant datacenter, providing location transparency of /dev/mars/mydata by local handover while the virtual device can stay mounted, in addition to geo-redundant long-distance handover and failover. about this event: https://programm.froscon.org/2022/events/2741.html

Wenn man den öffentlichen Diskurs zum Thema "Digitale Souveränität" verfolgt könnte man zu dem Schluss kommen, dass das Thema für einen selbst zu groß und abstrakt ist, als dass man es selbst durchdringen geschweige denn selbst etwas tun kann. Wir schauen uns gemeinsam aktuelle Vorkommnisse an bei denen so einiges schief läuft. Da ich selbst nicht verzweifeln möchte bringe ich dann auch Handlungsoptionen mit, mit denen wir die Welt zwar vielleicht nicht retten, aber zumindest etwas besser verstehen und auch etwas besser machen können. about this event: https://programm.froscon.org/2022/events/2818.html

OpenStreetMap is a collector's dream. While there is a finite set of stamps or coins, there are millions of shops and beauty salons, and new ones are opened every day. Yay, collect them all for the map! (And make the map better in the process, of course.) Alas, this task was made tedious, virtually impossible by our current tools. Not as much for adding — but for updating the data we've already collected, and finding what's missing. I've talked many times of this problem, and this year I think I've fixed it. This year changes everything for how POI are handled in OpenStreetMap. Last year I presented the idea of making cartography apps without a map for the central UI element. And added a couple drawings of a better editor for POI. Well, it is finally out there, and hundreds of mappers have already surveyed... a lot. So one part of this talk is a typical OSM editor talk: I'll walk you through the design decisions, show some statistics, and elaborate on how writing a new OSM editor is akin to writing a new browser these days: an enormous task, but with a lot of open source code at hand. But what is different, is that this editor is not a toy and not a general-purpose tool. It is very focused (well, on three things at once, but still). Meaning, you don't play with the map in it, and don't get lost in menus. You survey. Lots and lots and lots of shops and amenities are going to get added or confirmed. This editor does not just "allow" anything. It changes the landscape of OpenStreetMap. Before it shops were an afterthought — now people would seriously consider using OSM for searching. Here's where my experience in working with commercial places data comes in handy. Let's see what can we get out of this, and why "fun" is still as important in OSM mapping as always. about this event: https://2022.stateofthemap.org/sessions/ACCWJY/

The last 10 years were quite turbulent for the iD editor: After the initial idea from Richard Fairhurst was quickly picked up by a developer team at Mapbox, the editor became OSM’s default map editor almost exactly 9 years ago today. Since then, different Maintainers have managed the project, constantly enhancing its functionality and data models like iD’s built in tagging presets. This talk will present a condensed overview of the evolution of the iD editor since 2012 and, more importantly, showcase what still lies ahead of it: Small and large improvements to the user interface, performance, data validation, customization, integration of external services and more. Almost exactly 9 years ago, the iD editor became OSM's default editor. But its core idea was first presented even a year before that. Looking back at the past 10 years history shows that the project has undergone quite a few different phases: The initial sparks and the coining of the name by Richard Fairhurst were followed up shortly by a rapid development phase by a team of Mapbox engineers resulting in iD being ready to stand in as OSM’s default map editor. Since then, different Maintainers have managed the project, constantly enhancing its functionality and data models like iD’s built in tagging presets.. In the last couple of years, the iD editor has also seen some usage outside of the main OSM website, for example in the form of Forks like the RapiD editor, advancing the applicability in their own specialized use cases and scenarios. This talk will present a condensed overview of the development of the iD editor since 2012 and, more importantly, showcases what still lies ahead of it: Small and large improvements to the user interface, performance, data validation, customization, integration of external services and more. All with the goal to make iD fit for next 10 years and more to come. about this event: https://2022.stateofthemap.org/sessions/C9AKZK/

OpenStreetMap is a huge repository of geographic information – but how accessible is it? This panel aims at enlighting existing educational activities and platforms around OpenStreetMap topics, including editing, data usage and community governance, with the goal of exploring how new users and data consumers can approach OpenStreetMap in an easier way, and eventually widespread its adoption. During the panel we will discuss and share educational practices, experiences and tools and challenges. During the panel, we will discuss existing educational activities and platforms around OpenStreetMap topics, including editing, data usage and community governance. When first approaching OpenStreetMap, learning tools and activities may prove to be highly beneficial for new volunteers in several aspects as well as for expert mappers to improve their knowledge. Education around editing may lead to higher quality of data both during collaborative events or, in general, over all the mapper’s lifetime. Mappers may have knowledge on OSM editing and complete lack of understanding on how the data can be used for software or cartographic applications. On the other hand, many data consumers may not know editing practices and how the tagging schema is refined and discussed in the OSM community. Understanding how the OSM community is interacting and governing the project, including exposure to the guidelines related to good editing practices, organised editing, imports and licensing, may have companies and professionals better understand how to behave in this environment. The goal of this discussion is to enlist and explore all the tools and activities that organizations and communities are developing around education on OSM, with particular focus on the audience covered by those as well as the languages this material is offered through. about this event: https://2022.stateofthemap.org/sessions/SCBZ9Q/

Every day millions of users experience delightful features on Bing Maps. Each user, regardless of their technical background, possesses a wealth of local knowledge that can help improve map data which for many country regions comes from OpenStreetMap. The common OSM editorial tools iD & JOSM are far too advanced for our users. Hence, we embarked on a mission to build a very simple tool - MapBuilder - that can guide users to volunteer their local knowledge to update map data via a set of guided screens. This talk will focus on the following: - First features - Building community engagement - Identifying data gaps - Potential risks and mitigations about this event: https://2022.stateofthemap.org/sessions/B7VADW/

OpenStreetMap has proven to be a really interesting and valuable classroom instrument. Making students work with OSM allows them to develop the soft skills entailed in cooperation, to interact with something bigger than their class or school and to give their contribution for the sake of the collectivity. In this particular experienced, we worked on the local area of Bari with a class with 17 female students of a "Liceo Economico-Sociale", a school not particularly engaged in the STEM field. Thus, we also wanted to help them get more confident with the STEM field, which desperately need more diversity. Furthermore, focus has been on accessibility. During the talk, we will explain what we did during the project and the outcomes. The activities involved: * an introduction to OpenStreetMap, ID editor, licenses, but also Wikimedia projects * a phase of physical mapping, in which we visited the city centre of Bari using field papers and StreetComplete to map shops/restaurants/cafes and their accessibility status, accessibility ramps and other useful information to add both on OpenStreetMap and on Wikivoyage * the editing of OpenStreetMap and Wikivoyage to add the information gathered. In addition to what explained in the abstract, we would like to underline how the experience benefited equally the territory, thanks to the improved geographical information and also tourism information, the students, because of the worthwhile experience they have gained and the rediscovery of the STEM field, and the community, not only because of the new information added but also due to the increment (even if little) of diversity in contributors. As explained, we did not contribute only to OpenStreetMap, but also to Wikivoyage, the official, non-commercial and freely-licensed (CC-BY-SA) sister site of Wikipedia for tourism guides, and to Wikimedia Commons, the free multimedia database of Wikimedia projects. The two of us, Ferdinando Traversa and Rosa Colacicco, are respectively the regional coordinator for Apulia and the OpenStreetMap coordinator for Apulia of Wikimedia Italy/OpenStreetMap Italy, so the project was endorsed and sponsored by the organisation. This project is consequently also an example of synergy between OpenStreetMap and Wikimedia projects, strenghtened by the fact that in Italy chapters for WMF and OSMF coincide. Rosa Colacicco is also the president of the YouthMappers@UniBA, the local group of YouthMappers which collaborates with the department of Geology of the University of Bari. In conclusion, we would like to present this experience as a case study in order to enable others to try a similar pathway. about this event: https://2022.stateofthemap.org/sessions/GCLYZE/

Der Vortrag erläutert das Konzept “Container-optimiertes Linux” und gibt einen Überblick über die wichtigsten Features und Arbeitsabläufe sowie deren Umsetzung in Flatcar Container Linux. Abgerundet wird die Präsentation mit einer kurzen Live-Demo einer Flatcar-Provisionierung. </p> <p> Das Konzept “Container Linux” wurde ursprünglich von CoreOS beim ersten Release dieses Projektes um 2013 herum definiert. Das Projekt wurde leider 2020 beendet. Flatcar, begonnen als “friendly fork” von CoreOS, ist nach dessen Abkündigung zu seinem “spirituellen Nachfolger” gereift und ist nun eine vollständig freie und auf Open Source Software basierende Distribution, entwickelt von und für unsere Community. </p> <p> Containerzentrische Systeme wie z.B. Kubernetes bieten durch ihre Sandbox eine strikte Trennung von Betriebssystem / Laufzeitumgebung und Applikationen. Wir nutzen diese Trennung in Flatcar, um das Betriebssystem ähnlich automatisiert provisionieren, konfigurieren, betreiben und aktualisieren zu können wie z.B. Kubernetes-Admins das von ihren Applikationen gewohnt sind, und stellen diese Mechanismen im Vortrag vor. </p> <p> Der Vortrag richtet sich an Administratoren und Ops sowohl von Einzelsystemen als auch von Clustern mit Container-/ Kubernetes-workloads und an alle, die sich dafür oder für automatisierte Infrastruktur interessieren. </p> about this event: https://programm.froscon.org/2022/events/2774.html

Über GraphQL Federation können Microservices in eine umfassende API zusammengefasst werden und dennoch individuelle Clientanfragen verarbeiten. Für einen führenden Video on Demand (VoD) Anbieter ist es wichtig, auf dem Abspielgerät präsent zu sein, das der Kunde verwendet. Um die Top 20 der Abspielgeräte mit den neusten Features zu versorgen, muss die Plattform im Hintergrund die notwendigen Daten zügig anbieten und Redundanzen in der Entwicklung vermeiden. Microservice-Architekturen sind heute der Standard in digitalen Plattformen. Jedoch gibt es einige Herausforderungen, um z. B. Feature-Teams eine universelle API effektiv umzusetzen. GraphQL als Orchestration Layer mit den Microservices verhilft Frontends zu einem optimalen Zugriff auf die benötigten Daten. Der Talk erklärt die Vorteile von Microservices für digitale Plattformen und wie GraphQL dazu beitragen kann - nicht nur für VoD-Dienste. about this event: https://programm.froscon.org/2022/events/2805.html
