A little time jump into the past when Christoph Roland and Harald Kuck ported SAP software stack to Linux.

In this episode, host Karsten Hohage speaks with Christoph Roland (former SAP) and Harald Kuck (SAP) about the past – when they both ported SAP software stack to Linux back in the 90s. Today Linux provides an open-source-based operating system infrastructure for SAP solutions. In the podcast Christoph and Harald share anecdotes and insides from the very beginning of Open Source and SAP.

Guests:

Christoph Rohland

Chrstoph Rohland discovered Linux at university in early 1993 and was convinced that Linux it had a great future. He joined SAP in 1994 where he started in the support organization, but soon joined Harald’s development team. Christoph took care of SAP’s network library – and ported the SAP stack to Linux. He then founded the SAP LinuxLab. Later he took on several management roles. He left SAP in 2008 to pursue other opportunities.

He started his career at Siemens and Karlsruhe University, before joining SAP in 1989, where he was part of the team implementing the R/3 kernel in C. Since then, Harald has founded several SAP technology development teams, including the SAP JVM team in the Java space or the Steampunk team in the ABAP space. One of the highlights of his 38-year career was initiating SAP’s move to Linux and open source, together with Christoph, in 1999.

What is Open Resource Discovery (ORD) and how can it be used and implemented inside SAP and beyond?

In this episode, host Karsten Hohage speaks with Simon Heimler (SAP) about Open Resource Discovery (ORD) – a protocol that allows applications and services to self-describe their exposed resources and capabilities. Simon explains in more detail what ORD is, how it’s used and where at SAP we already use ORD or plan to use it in the future. As the platform is an open standard by SAP geared towards the SAP ecosystem, how do we ensure a correct adoption of ORD at SAP? And how can it be helpful for individuals outside of SAP?
