This document discusses ScrumOps, which combines Scrum and DevOps practices. It defines DevOps as enabling organizations to quickly and safely develop, test, deploy, and operate software through collaboration between development and operations teams. Key DevOps principles discussed include continuous integration, delivery, feedback, and improvement. The document recommends practices like infrastructure as code, automation, and measurement to establish a collaborative culture between Dev and Ops.

ScrumOps – Practical DevOps NAVEEN KUMAR SINGH P R O F E S S I O N A L S C R U M T R A I N E R ( P S T )
NAVEEN KUMAR SINGH Software Development Coach Facilitate Scrum.Org (PSM, PSD) and Scrum Alliance (CSD) Training Teaching and coaching teams on agile and Technical Practices in India, Sri Lanka, Malaysia, Singapore, Indonesia, Hong Kong, Saudi Arabia, Dubai and Philippines. Strength – Knowledge about Scrum, Kanban and Scaling Agile (LeSS, Nexus, Spotify). Hands-on TDD, BDD, CI/CD, DevOps, Emergent Design and Agile Testing Automation Weakness – Don’t go by book and don’t like prescriptive frameworks
DevOps Enables organizations to create a safe system of work, where teams are able to quickly and independently develop, test, and deploy code and value quickly, safely, securely, and reliably to customers. By adding the expertise of Dev, QA, IT Operations and Infosec into delivery teams and automated self-service tools and platforms, teams are able to use that expertise in their daily work without being dependent on other teams. Allows organizations to maximize developer productivity, enable organizational learning, create high employee satisfaction, and win in the marketplace.
First thing First
Still it is not just about tools DevOps Tools Process People
DevOps History Patrick Debois and Andrew Shcafer presented paper in Agile Conference, Canada in 2008. They talked about applicability of Agile Principles in Infrastructure. John Allspaw and Paul Hammond gave the seminal “10 deploys per Day: Dev and Ops cooperation at Flickr during Velocity conference in 2009 Patrick Debois got inspired by above idea and created the first DevOpsDays in Ghent, Belgium in 2009. There the term “DevOps” was coined.
Dev or Ops? Software deployed but server showing all red (CPU, RAM etc.) Software deployed but email not working There is issue with the build. Code is not building. Software deployed in QA but testers not able to login Software deployed but HTTPS not working Breaking in production but unable to reproduce on my system
Looks familiar? I spent 70% time in waiting I don’t have spare capacity Test System are not realistic Developer IT Guy Tester How to escalate? I am constantly fighting fires What is IT doing? L1 Support App Support LOB head
Traditional Approach Specification Coding Test cases Testing Deploy Rework Support AGILE PROCESSES WATERFALL?
So what is DevOps? Source – Wikipedia. Venn diagram showing DevOps as the intersection of development (software engineering), operations and quality assurance (QA) NO. This is not DevOps
So what is DevOps? Methods for Improving Communication CollaborationIntegration Between DEV and OPS
Collaboration Benefits
Processes Vs Values Business Failure Useless Stuff Business Success Technical Debts Technical Practices Build it Right Build the Right Product
Collective Ownership of Delivery Engineering Practices like TDD, BDD, Pair Programming, CI/CD, Agile Testing and DevOps etc.
DevOps and Agile? Code Build Test Release Deploy Operate Popular Agile Methods DevOps
DevOps Principles The Three Ways System Thinking Amplify Feedback Loop Continuous Improvement CAMS Culture – People, Process, Tool Automation – Infrastructure as Code Measurement - Everything Sharing – Visualization, Feedback
Shifting Left
Smaller Batch Size Large batch size create bottleneck and takes more time to complete work Small batch size helps in reducing waiting time so increase throughput Release daily vs Monthly release
PRACTICES FOR EFFECTIVE DEVOPS
