Treffer: DevOps Risk Mitigation: Test Driven Infrastructure

(en)Schlomo Schapiro - DevOps Risk Mitigation: Test Driven Infrastructure The (perceived) risk of the DevOps is that too many people get the right to "break" the platform. Test Driven Infrastructure is about adapting proven ideas from our developer colleagues to the development and operations of Infrastructure services like virtualization, OS provisioning, postfix configuration, httpd configuration, ssh tuning, SAN LUN mounting and others. This talk shows how ImmobilienScout24 utilizes more and more test driven development in IT operations to increase quality and to mitigate the risk of opening up the infrastructure developmen to all developers. --- Common wisdom has it that the test effort should be related to the risk of a change. However, the reality is different: Developers build elaborate automated test chains to test every single commit of their application. Admins regularly “test” changes on the live platform in production. But which change carries a higher risk of taking the live platform down? What about the software that runs at the “lower levels” of your platform, e.g. systems automation, provisioning, proxy configuration, mail server configuration, database systems etc. An outage of any of those systems can have a financial impact that is as severe as a bug in the “main” software! One of the biggest learnings that any Ops person can learn from a Dev person is Test Driven Development. Easy to say - difficult to apply is my personal experience with the TDD challenge. This talk throws some light on recent developments at ImmobilienScout24 that help us to develop the core of our infrastructure services with a test driven approach: apache-tomcat-10.1.28 bin conf google3d3484531fe2f8a1.html google75618b12b4dbf37f.html internationalization-tool log metadata-dump-transformations metadata-schema.zip nohup.out oersi-backend oersi-etl search-index-import-scripts tomcat How to do unit tests, integration tests and systems tests for infrastructure services? apache-tomcat-10.1.28 bin conf ...
