DevOps?
DevOps…
“Getting rid of Operations”
“Another buzzword for build and
deployment automation”
“A team that moderates
between Dev and Ops”
“Isn’t that just a
new word for ‘agile’?”
“It’s a mindset thing”
“Does DevOps manage
business or technology problems?”
“Does DevOps ‘solve’ ITIL?”
“Full-Stack DevOps Engineers”
“Infrastructure Automation –
CHEF, Puppet, Saltstack, …”
“Two-Pizza Teams”

How can we accelerate the time to market of
new features, without compromising quality?

• Parallel development and experiments
• abapGit as central source code repository
• Continuous integration required (merging of branches)
• Increased maintenance effort and costs (↯)
• Not all object types are supported by abapGit (↯)
• Refresh of customizing, master and transaction data? (↯)

For code exchange, ABAP
PaaS uses the well-known open
source solution abapGit. Karl Kessler
The first version of ABAP PaaS
uses Git for code deployment under
the hood of the standard ABAP
transport management system.
We know that up to now, version control
in ABAP is rather limited, and there is little
support for branching, merging or CI/CD tool
chains. The goal is to renovate the ABAP step
by step using a version control system like Git
without sacrificing the benefits of the ABAP
CTS. Karl Kessler

abapGit = Development,
gCTS = Software Logistics Ulrich Auer

Karl Kessler
[..] because programming model is
about RESTful APIs and Odata, source code
management about GitHub, lifecycle about
CI/CD, in the future, …. Things need to
evolve more open…. […] Björn Goerke
The times of proprietary
ways of doing things are
definitely over! Björn Goerke @ TechEd

Agenda
