THE DEVOPS MOVEMENT
DevOps is a movement that stops wasting time, money to begin delivering great software and creating lasting systems. The movement is created around a group of people who believe that the app of a combination of the right technology and attitude could revolutionize the software development and delivery environment. The movement is bold enough to believe that there is a better way of building teams and software that could solve system problems.
The DevOps movement is characterized by people who possess a multidisciplinary skill set, persons who are comfortable with configuration and infrastructure, but at the same time happy to roll up their sleeves, debug, write tests and ship features. These are people who make connections since they could, because they have feet in numerous camps, they could be peace makers, ambassadors, facilitators, and communicators. The point of the movement is to encourage people, compare ideas, train, recruiting and popularizing this method of doing IT.
The DevOps movement is attempting to encourage development of understanding the domain which the software is written, communication skills and crucially, a passion and sensitivity for the underlying business and for ensuring that it would succeed. Born of the need to boost IT service delivery agility, the movement puts emphasis on collaboration, communication and integration between software developers and Information Technology operations. DevOps recognizes the interdependence of IT operations and software development and helps a business create software and IT services faster, with frequent iterations.
Organizations that integrate DevOps practices get more done, simple and plain. They deploy code up to thirty times more often than the competition. Collaboration across the various roles deliver a lot of benefits.
TECHNICAL BENEFITS OF DEVOPS
- Less complex issue to fix
- Continuous software delivery
- Faster solution to problems
- More stable operating systems
- Faster features delivery
- More time available for adding value
DevOps is not just another Information Technology buzzword. It is here to stay. A big majority of businesses either have already implemented DevOps practices or planning to implement them. It is characterized by operations staff that make use of a lot of the same techniques as developers for their systems work. The idea is that rather than avoiding each other in the work place, the development and operations people must learn to work together in numerous cooperation.
DEVOPS AFFINITIES WITH AGILE AND LEAN APPROACHES
DevOps has strong affinities with Agile and Lean approaches. It could be interpreted as agile outgrowth. Agile development prescribes close collaboration of clients, developers, product management and at times QA to fill in the gaps and iterate quickly towards a better product. Simply, DevOps is extending Agile principles beyond the code boundaries to the whole service delivered.
WHY DEVELOPERS SHOULD WANT DEVOPS?
DevOps is great for developers. There are three principal reasons that a developer would want to work in an organization that is DevOps-oriented. Developers who work in DevOps-mode receive lesser calls in the middle of the night for resolving production problems. This is because they see problems before they become catastrophic issues because of an orientation of proactive monitoring instead of reactive alerts.
In a traditional software process, once a software is developed, it is ‘thrown over the wall’ to QA, which throws it over later to another wall to production. Thus, what the end-user ultimately sees could be a bit different from what a developer wrote. But, under the DevOps model, what a developer writes goes live since one continues to have access and visibility to the code even after it goes to QA and production. In other words, developers own the code delivery from creation to implementation.
Developers, such as most human beings, get greater satisfaction from work with relevance in the real world. As the developers in a traditional organization are isolated, often they work on simulated problems in made-up use scenarios and they just find out that these approximations were wrong when something will break. In a DevOps model, the scenarios are real. For instance, environments are load tested before they are put into production to determine if they work correctly. Another instance is that test scripts are, themselves tested for realism via being deployed in a production environment, not only test labs. Sharing the test results with developers provide them the chance to see how their code will perform under real-life scenarios.
DevOps need an orchestra leader. Selling a DevOps environment is all about understanding what is relevant to management. Is it moving higher quality, moving faster? Is it about developers more accountable for their code? All these come about by way of a DevOps environment.
