SAP Inside Track Berlin 2018 - DevOps in ABAP Landscapes

202 views

Published on

DevOps has become a widespread movement in the world of IT and has shown that agility and quality are not mutually exclusive. However, the world of SAP ABAP has so far successfully resisted and DevOps is more a buzzword than actual practices which are used to deliver value to the customer.

Since July 2017 a team of DSAG* members has been working to define the meaning of DevOps for SAP ABAP system, what are the reasons why ABAP is still considered a “special snowflake” and how concepts like continuous integration and delivery could be adapted.

This presentation highlights the main topics of discussion and is explicitly marked as work in progress, but will hopefully bring others to join the discussion and prove the concepts in the real world.

*The DSAG is a group of over 3000 companies which represent a big portion of the german speaking part of SAP customers. They all work together to shape the SAP portfolio to the actual need of SAP customers, inform about new SAP technologies/services and offer a community to discuss and learn from each other.
