DevOps?

● Collaboration: Development (Dev) and Operations (Ops)

● Bring agile software engineering methods to operations

– Automation: infrastructure as a code, versioning/rollback

– Testing: continuous integration/testing/deployment● Bring operations engineering experience to developers

– Scalability: independent microservices

– Production insight: monitoring/logging/metrics● Together: make the application's owner happier


Dev + Ops collaboration

● Bring together Developers & Operations

● Practice agile Operations Engineering

● Counter fear of change with (automated) testing

● Provide developer and development infrastructure

– Tools for developers, preferably self-served


Infrastructure as code

● Change from hand-groomed servers to Operations Engineering (from pets to cattle)

● Speed & reliability

● Versioning & rollback

● Prerequisite for self-service

– Give each developer a full stack

– No manual changes in production

– As many testing instances as needed


Infrastructure tools

● Packaging code & dependencies for atomic deployment/rollback

– Deb/rpm, docker● Infrastructure state management (configuration mgmt)

– Puppet, salt, chef, ansible● Continuous Integration/Testing/Deployment

– Jenkins/TravisCI/GitlabCI● Self-Service

– Vagrant/Docker or through Continuous Deployment


Infrastructure testing

● Bring software engineering best practice to operations

● Large complex infrastructure (as code) → many moving parts

– Unit testing each module (webserver setup, database setup, cache setup, etc)

– Functional end-to-end testing of full stack (request to cache delivers content from database)

● Basically the same thing as production service monitoring but for each change


Infrastructure feedback

● Collect all logs in Elasticsearch-Logstash-Kibana

– Let the developers search for prod error root cause ● Collect Server & Application Metrics

– Correlate with deployments & site traffic


Software Delivery Automation

– Nginx, Varnish

– PHP versions 5.6 and 7

– MySQL/MariaDB-Galera-Cluster

– Memcached/Redis/Solr/Elasticsearch● Application Deployment/update (Ansible/SSH)

● Bundle know-how (settings, tunings, etc.) in common module, override if necessary per customer through YAML-File in Git-Repository

● Docker image for local testing/developing
