1 Introduction to DevOps
Introduction
DevOps is notorious for being difficult to define yet it's value has proved beyond doubt. It is not just the so called "Unicorns" like Netflix and Amazon, more "traditional" companies like GE and Walmart have transformed their fortunes with the adoption of DevOps. The most common question we hear about DevOps is "how do I start". This course defines DevOps and the core principles and methodologies that underpin it. People are the key to successful adoption and the course focuses heavily on how to successfully transform a companies culture, breaking down traditional silos etc. Cross-functional processes and the tools and methodologies that support them follow. Who should attend
We would recommend any company about to start or in the process of a DevOps transformation undertake this course. The course is available on a public schedule running at least once per month and also on site. Attending the course will ensure the same base level of understanding and appreciation of what's required to achieve a DevOps culture, the first and most important step in adopting DevOps.
Course Objectives Students will walk away with a solid understanding of what DevOps is and how to implement common DevOps practices, including:
● What is DevOps, and why is it important ● Understanding the different DevOps principles ● Understanding DevOps practices ○ Continuous Integration ○ Test Automation ○ Continuous Delivery ○ Infrastructure as code ○ Monitoring ○ Microservices ○ Containerisation ● Pipeline Orchestration ● Transitioning to DevOps ● Examples of DevOps in practice ● Introduction to DevOps Certification
