A Culture and mindset for collaborating Between Developers and operations. DevOps is a term for a group of concepts that, while not all new, have catalyzed into a movement and are rapidly spreading throughout the technical community.
The specific goals of a DevOps approach span the entire delivery pipeline. They include improved deployment frequency, which can lead to faster time to market, lower failure rate of new releases, shortened lead time between fixes, and faster mean time to recovery in the event of a new release crashing or otherwise disabling the current system. Simple processes become increasingly programmable and dynamic, using a DevOps approach, which aims to maximize the predictability, efficiency, security, and maintainability of operational processes. Very often, automation supports this objective.
DevOps integration targets product delivery, feature development, and in order to improve reliability and security and provide faster development and deployment cycles. Many of the ideas involved in DevOps came from the enterprise systems management and agile software development movements.
DevOps aids in software application release management for an organization by standardizing development environments. Events can be more easily tracked as well as resolving documented process control and granular reporting issues. Companies with release/deployment automation problems usually have existing automation but want to more flexibly manage and drive this automation — without needing to enter everything manually at the command-line. Ideally, this automation can be invoked by non-operations employees in specific non-production environments. The DevOps approach grants developers more control of the environment, giving infrastructure more application-centric understanding.
DevOps is a software development method that stresses communication, collaboration, integration, automation, and measurement of cooperation between software developers and other information-technology (IT) professionals.
Companies that incorporate DevOps practices get more done, plain and simple. They deploy code up to 30 times more frequently than their competition. And less than 50% of their deployments fail according to Puppet Labs 2013 State of DevOps survey.
The biggest shift in attitude in a DevOps environment is that there is one team composed of cross-functional team members including developers, QA, DBAs, business analysts, operations engineers and so forth. Collaboration across these different roles delivers many benefits.
• Continuous software delivery.
• Less complex problems to fix.
• Faster resolution of problems.
• Faster delivery of features.
• More stable operating environments.
• More time available to add value.
Experiment on many different things for continuous incremental improvements of whatever your company measures, be it performance, sales or signups.
There is enormous waste in a typical IT environment with people waiting for other people, other machines, new software or they are stuck solving the same problems over and over. People like to be productive in their work and the time spent churning causes frustration and unhappiness. When people get rid of the unsatisfying parts of their job and can instead spend that time adding value to the organization, everyone benefits. Automated deployments and standardized production environments, key aspects of DevOps, make deployments predictable and free people from routine repetitive tasks to go do more creative things.
Gartner Says By 2016, DevOps Will Evolve From a Niche to a Mainstream Strategy Employed by 25 Percent of Global 2000 Organizations Technology That Supports the DevOps Tool chain is Predicted to Grow 21 Percent Worldwide. As per Gartner, The DevOps trend goes way beyond implementation and technology management and instead necessitates a deeper focus on how to effect positive organizational change. The DevOps philosophy therefore centers on people, process, technology and information.
