The Open Source Way

In this episode Karsten Hohage talks with our guests Michael Bernhardt and Artem Smotrakov about Fosstars, a java-based framework that allows you to define various ratings for open source projects. The name “Fosstars” is a combination of “FOSS” for “Free and Open Source Software” and the concept of rating products or services with “stars”. It helps software engineers and architects to quickly assess various aspects of open source components, such as their security, maturity, etc. It is often difficult to analyze the actual code of all the open source components in an application and compare them with respect to various aspects. To make it easier, Fosstars offers ratings that are based on publicly available information about the projects, such as adopted security tools and best practices, activity of the community,  and many more. Thus, Fosstars is a project, that deals with other open source projects, making the natural approach to it – guess what – open source!

Michael Bernhardt works as a program manager for SAP’s Open Source Security Strategy and DevSecOps lead in SAP’s corporate security organization. He also acts as a security advisor as part of the SAP Open Source Program Office (OSPO).

In this episode Karsten Hohage talks with our guests Klaus Häuptle and Florian Hoffmann about the importance of having a readable and maintainable codebase to ensure sustainable development. Klaus and Florian started an internal repository with best practices for maintainable and readable ABAP code. Through info sessions with many hundreds of participants, intense discussions, and great contributions, SAP colleagues helped turn this into a treasure trove for modern ABAP’ers. Many developers asked if this would become available as a book, and if they would be allowed to share it with customers and partners. They soon realized that this initiative gained its early drive from its community and needed to remain part of that community. Thus, they opened it to contributions from inside and outside of SAP, hoping that this repository would help developers worldwide to make their ABAP code a little cleaner. In late 2020, they published the book “Clean ABAP” to help individual developers, teams, and entire organizations with learning and implementing clean ABAP.

Klaus Häuptle is a software engineer who worked on different products and technologies in the areas of governance, risk, and compliance and supply chain management. During his career he has also been a trainer, coach, and product owner for agile software engineering. Currently, he mainly drives craftsmanship topics across SAP and is a curator for a large internal community with the intention to improve engineering topics by strengthening collaboration.

In this episode Karsten Hohage talks with our guests Andreas Kunz and Peter Muessig about OpenUI5. OpenUI5 is a JavaScript-based web user interface framework. One that specifically targets enterprise use cases, but can be used for any type of application. Andreas and Peter explain how OpenUI5, SAPUI5, and SAP Fiori are related and how OpenUI5 became an open source project. They elaborate why the modular structure of this probably largest open source project from SAP is an optimal fit for a community approach. Our guests also have some interesting examples how OpenUI5 has been used not only by SAP customers, but also by nuclear scientists as well as completely private individuals building an app for their kids. Overall, OpenUI5 engages a large community of contributors and followers, manifest in five-digit enrollment in online courses and very popular community events.

Andreas Kunz works at SAP since 2005 and has been with UI5 from the very beginning in various roles, now as a lead architect. He is always eager to engage with the outside community and an advocate for openness and open source.

In this episode Karsten Hohage talks with our guests Krasimir Semerdzhiev and Valentin Vieriu about project „Kyma”. Kyma is an open source project built on top of Kubernetes that provides a platform to build extensions for cloud applications. Krasimir and Valentin talk about all the investigations, challenges, and learnings that come with such a project. We learn how and why Kyma got started, where the strange name comes from, and why it is an advantage for contributors that Kyma is based on Kubernetes. The episode also touches how Kyma scales, how it relates to other open source projects inside and outside the Cloud Native Computing Foundation (CNCF) and how you can get involved.

Krasimir Semerdzhiev is a true open source enthusiast. He works as a chief architect in the SAP CTO Office where he leads a Northstar Architecture workstream, defining the end-to-end experience for implementation partners and Independent Software Vendors (ISVs), who extend and customize SAP products. Having spent the last 20 years in technology development in various roles, he is a prominent evangelist for the adoption of cloud native architecture principles both internally and outside of SAP.

Valentin Vieriu works as a community manager of project „Kyma“. He has been tinkering with the Web for more than 15 years. During this time, he gathered a 360° understanding of how the Web works – from product management via UX, design, and front end, all the way to back end and DevOps. A passionate front end developer at heart, his new goal is to make sure machine learning becomes an easy to use concept for every problem to solve. Whenever you do not find him building web apps or training neural networks, he’s probably strengthening his knowledge about Kubernetes and cloud native application patterns.

In this episode Karsten Hohage talks with our guests Vasu Chandrasekhara and Tim Usner about project Gardener. Today, Kubernetes is the natural choice for running software in the cloud. More and more developers and corporations are in the process of containerizing their applications, and many of them are adopting Kubernetes for automated deployments of their cloud native workloads. There are many open source tools which help creating and updating single Kubernetes clusters. However, the more clusters you need and the more infrastructures need to be supported, the harder it becomes to operate, monitor, manage, and keep all of them up-to-date. And that is exactly what project Gardener focuses on.
Vasu and Tim explain in more detail what Gardener does, why open source is the natural approach to such a project, and how it makes the lives of cloud developers, architects, and operators easier.

Tim Usner

Tim Usner joined SAP after studies in information technology. He started his career as a business software developer and later switched to the Gardener project in 2018. Besides his contributions to core components of Gardener, he has advocated the project at different events and supported development teams with their transition to Gardener and Kubernetes. He is passionate about working in the open source space where the project evolves every day, thanks to a growing and contributing community.

In this episode Karsten Hohage talks with our guest Fabienne Haag about the Open Source Outbound Process at SAP and how it was implemented. During the last few years, SAP has been actively initiating and maintaining its own open source projects. Many SAP employees contribute to these projects or to completely different ones. This led to the need to have a simple and transparent process in place. The new Open Source Outbound Process enables developers to easily and quickly start new open source projects and contribute to existing projects – both in a compliant and secure manner. The entire approval workflow is executed in Enterprise GitHub, which is close to the developer community and gives them an easy way to manage their open source contribution requests.

Fabienne Haag

Fabienne Haag works at SAP Global Licensing. She is responsible for compliance requirements of the usage of open source components in SAP products. In addition, she is deeply involved in the open source outbound process.

In this episode Karsten Hohage talks with our guest Michael Picht about InnerSource at SAP and why it should be the default development model at SAP. InnerSource is the practice of applying methodologies and best practices from open source projects to in-house software development. In an InnerSource approach, projects are open for contributions from other teams. This implies that they accept and build on these contributions – just as an open source project would. The major difference are the boundaries: the community is in-house, it only consists of colleagues, and the codebase cannot be accessed from outside of the company. 

By applying InnerSource in an enterprise software development context, you can increase quality, speed, collaboration, and developer joy. Moreover, especially large development organizations can break silos between different teams and encourage developers to expand their skills or use them to support cross-team projects.

SAP collaborated very closely with the German Government, Robert Koch Institute, Deutsche Telekom, and other partners to develop the Corona-Warn-App in an open source approach. The app warns the users if they have been in close proximity to someone diagnosed with COVID-19. This helps to trace chains of infection and provides guidance to people who have tested positive. The decentralized approach and pseudonymization ensure the highest level of security and data privacy. In this episode, our host Karsten Hohage talks to one of the community managers of the open source project, that was established to develop the Corona-Warn-App. If you want to learn more about The Corona-Warn-App go to: https://www.coronawarn.app/en/  or GitHub: https://github.com/corona-warn-app and share your ideas with us: [email protected]
