DevOps¶

Definition and background: Lwakatare, Lucy Ellen, Doctoral Dissertation, University of Oulu, 2017, DevOps adoption and implementation in software development practice : concept, practices, benefits and challenges, <http://jultika.oulu.fi/files/isbn9789526217116.pdf> Read at least sections 2.1 and 2.2.

There is also this blog-type tutorial <http://dev2ops.org/2010/02/what-is-devops/>, but do not use that as the main reference in a thesis.

Everybody should not be an expert on everything, thus DevOps work requires special roles and organisation of the work:

About DevOps toolchain:

Periodic Table of DevOps tools, <https://xebialabs.com/periodic-table-of-devops-tools/>. This page divides the tools to categories and gives multiple examples.
“Improving the delivery cycle: A multiple-case study of the toolchains in Finnish software intensive enterprises” <https://www.sciencedirect.com/science/article/abs/pii/S0950584916301434> This research is from a few years back but shows the diversity of the tool chains.
