DEVOPS
 Background
The world is being transformed in fundamental ways with software and communication technologies. As bits reshape and pervade the
atoms, connecting us and the world around us, most businesses find themselves in a struggle to survive, to transform themselves and to
be relevant in the times to come. Design thinking led approaches are gaining ground, helping businesses uncover unknown problems and
solve the known problems, as part of their transformation journeys. Majority of these transformation journeys are software led. The software
applications deliver high quality capabilities in a cost effective manner that keep the businesses ahead through demonstrated Speed and
Agility. This paper looks at the role of DevOps in driving Agility, its leverage across a variety of technologies and the Infosys recommended
approach in its adoption.

DevOps Adoption
DevOps is about enabling rapid delivery of capabilities to the end consumers, which requires collaboration across the software delivery value
stream that includes teams spanning across business, development, QA, and infra & ops. This entails embracing a set of capabilities that
deliver speed (faster development & frequent releases), quality (stability & resilience in production) and value. Software tools are an essential
part of DevOps and the key to orchestrating these capabilities seamlessly across this software delivery value stream.

DevOps adoption entails building a set there are certain key capabilities that are Management, Monitoring & Dashboards.

 DevOps Journey
1. Assessment and roadmap definition
DevOps journey typically starts with the organization readiness assessment. As DevOps impacts many functions like dev, test, business,
ops, infra; it is important to align the stakeholder towards adoption of changes in their way of functioning, governance or technology
implementation that will come with any DevOps adoption. Combined with a DevOps maturity assessment it serves to setup right
