All Rights Reserved Top concerns that we hear from customers are “How can we release on-time?”, “How can we have a stable release?” or “How can we address the problems before end users get impacted?” Happiest Minds answer them in a simple one-liner, “Embrace DevOps”.Whether you are a tiny startup, a mid-sized one or a Fortune 500 company, be informed that the IT industry is adopting DevOps at an amazing pace. Even then, majority of IT professionals either don’t know about DevOps or just have a partial understanding of the big picture. At Happiest Minds, we see DevOps as a business driven software delivery approach, an approach that takes a new or enhanced business idea from design to development to testing and all the way to production, providing business value to customers in an efficient manner. Whether you are a tiny startup, a mid-sized one or a Fortune 500 company, be informed that the IT industry is adopting DevOps at an amazing pace. Even then, majority of IT professionals either don’t know about DevOps or just have a partial under- standing of the big picture. We explain here the basic concepts of DevOps and why you should embrace it. • What is DevOps? • Do we really need DevOps? • How does DevOps work anyways? • Challenges and problems out there • Happiest Minds Approach – 7Cs of DevOps • How will you benefit from Happiest Minds DevOps Approach? 3 Introduction It’s DevOp! It’s DevOp! It’s DevOp! It’s DevOp! It’s DevOp! Patrick Debois, who’s often called “the father of DevOps”, coined the word “DevOps” in 2009. As the word depicts, it was formed by combi ning two words: “development” and “operations”. DevOps is a collaborative way of developing and deploying software. DevOps (a portmanteau of development and operations) is a software development method that stresses communication, collaboration and integration between software developers and information technology (IT) operation professionals. What is DevOps? • DevOps is an approach based on agile and lean principles in which business owners, development, operations, and quality assurance team collaborate to deliver software in a continuous stable manner • DevOps is an environment that promotes cross practicality, shared business tasks and belief • DevOps is a movement that improves IT service delivery agility • DevOps is a culture that promotes better working relationship within the company • DevOps is a set of practices that provides rapid, reliable software delivery It’s a movement of people who think it’s change in the IT Industry - time to stop wasting money, time to start delivering great software, and building systems that scale and last DEV Integration Ops Communication Collaboration Patrick Debois At Happiest Minds, we see DevOps as a business driven software delivery approach, an approach that takes a new or enhanced business idea from design to development to testing and all the way to production, providing business value to customers in an efficient manner.

Lee Thomson describes this as a wall of confusion between devel- opment and operations. This wall of confusion not only exists between the mindsets of the two teams but also with the tools they use. Development uses some tools and operation uses some other tools to perform the same stuff. Do we really need DevOps? Wall of Confusion Wall of Confusion At Happiest Minds, we see DevOps as a discipline, which allows us to bridge the gap between ongoing development and opera- tions. Development Operations I want Stability I want Change! One Team, One Goal Dev Tools Ops Tools What Drives the Need for DevOps? The need for greater collaboration between developement and operations terms A greater need for simultaneous deployment across different platforms Pressures from the business to release apps more quickly to meet customer demand or enter new markets Need to improve the end customer experience The increasing use of mobile devices (smartphones/tablets) The increasing need to develope or deploy cloud based applications An increasingly complex IT infrastucture that is part physical, part virtualised and part cloud Need to reduce IT costs ca.com: What is driving the need for DevOps now more than ever before?
