What is DevOps? - My Journey of becoming 'EXIN DevOps Master' Certified

I have recently become EXIN DevOps Master certified after passing the certification exam. This blog provides you with some background about DevOps and also about its certification process. 

DevOps is primarily associated with software development, but its principles are increasingly applied to other projects and processes. This makes DevOps interesting for IT professionals who want to broaden their knowledge to address the latest developments in IT management. Application developers, product owners, agile scrum masters, project managers, test managers, and IT service managers will benefit from this exam.

DevOps is a set of best practices that emphasize the collaboration and communication of IT-professionals (developers, operators, and support staff) in the lifecycle of applications and services, leading to:

  • Continuous Integration: easy hand-off from Development to Operations and Support
  • Continuous Deployment: release continuously or as often as possible
  • Continuous Feedback: seek feedback from stakeholders during all lifecycle stages
     

DevOps Principles and Concepts

Software Development Methodologies Waterfall, Agile, SCRUM
Operations Methodologies ITIL, COBIT
Systems Methodologies LEAN
Development, Release, and Development Concepts Version Control, Test-Driven Development, Application Deployment,  Continuous Integration, Continuous Delivery, Continuous Deployment, Minimum Viable Product
Infrastructure Concepts  Configuration Management, Cloud Computing, Infrastructure Automation, Artifact Management, Containers
Cultural Concepts Retrospective, Postmortem, Blamelessness, Organizational Learning



As per the Master program that I recent passed, please note that the EXIN DevOps Master program is an advanced level certification that teaches candidates a combination of principles, knowledge and practical skills. This enables them to introduce and promote DevOps in their organization to better manage application and service lifecycles and facilitate collaborative work.

  • Adoption of DevOps

  • Development and deployment
  • Operation and dimensioning
