DevOps Practitioner

DevOps is an emerging practice supporting fast, sustainable software delivery and infrastructure changes through automation while encouraging collaboration of development and operations teams.

This five day DevOps Practitioner course is designed to give learners from both Dev and Ops teams experience in deploying modern, large scale complex systems in the cloud using a DevOps tools chain to create an end to end pipeline supporting continuous integration, configuration management, system provisioning, containerisation, continuous deployment, continuous delivery and continuous monitoring of software delivery and infrastructure changes.

Day one is an introduction to what DevOps is and how the tools we use can help in its realisation. We then look at cloud-based systems and beginning our pipeline by building and managing a distributed version control system for code collaboration using git.

Day two is concerned with continuous integration and deployment whereby we will automate the testing and packaging of code changes made in a git repository using Jenkins.

Day three focuses on containerisation of code, automating the creation of sustainable and deployable environments using Docker and container orchestration with Docker-compose.

Day four moves onto automation of configuration management and rapid infrastructure provisioning. Terraform and Puppet will be added to the tool chain to support high site reliability.

The final day will consist of exploring The Three Pillars - Measurement, Metrics and Tracing with an introduction to Elasticsearch (ELK) and a practical exploration of continuous monitoring with Zabbix 5 to support the maintenance of a healthy infrastructure.
