Some see it as DevOps vs. Agile while others see them as two sides of the same methodology coin. Others would say Agile empowers DevOps to exist.
Back in 2009, more IT professionals started to move away from the traditional waterfall method and adopt nonlinear agile methodology by creating each development stage independent and incorporating continuous testing early on and throughout the growth cycle (see the next half of the manual for a glossary of terms which goes into more detail):
Consequently, this strategy enhanced efficiency and reduced risk by allowing developers to make immediate changes before shipping to production depending on the continuous feedback they have received. While agile procedures had always enhanced development, there was still a discrepancy at the flow as it came to installation, which still embraced the waterfall strategy.
While development utilized agile to reduced risk and improve efficiency, deployment hung on to the linear waterfall construction, slowing down delivery and leaving testing to the end of the process -- a process which wrongfully divides ownership. This generated huge bottlenecks in shipping cycles because programmers would need to start from the beginning if a problem were found close to the end of the deployment.
It was seeing this disconnect between development and installation as well as understanding the benefits of adopting agile in all facets of software delivery that Debois came up with the notion of DevOps. The union of development and operations along with the extended best practices and principles connected with agile had the capability to greatly increase efficiency and lower delivery dangers.
DevOps isn't a tool nor a strategy. It is really more of a cultural shift. Change is feared throughout most organizations of any type, so the adoption of new methodologies can quite challenging. Therefore, it is vital first to define the company's need that brought on the discussion on the possible change as well as the corresponding challenges. These days, businesses are expected to swiftly deliver perfect software that is focused on user experience, but without the right tools, applications, and behavior, this seemingly simple task can become a complicated mess. Finally, faulty delivery translates into lost business chances.
DevOps culture can reside only in environments where everybody is on board with all the philosophy. If everyone in an IT company is on the same page and knows the power of clear and consistent communication in addition to the underlying business objectives, then the sky's the limit. Obviously, obtaining a broad skill set is helpful to every aspect of the procedure, provided that those lucky individuals are prepared to function as team players.
DevOps Needs Unified, Multi-Skilled Teams
The evolution of developer methodology in the last decade has witnessed the decline and emergence of different functions --from sysadmin into SRE, then from SRE to DevOps engineer. This career path is consequently common to see about the resumes of many folks in the developer's and engineer's planet, as the methodologies demanded and expectations expected of new hires evolves.
As stated previously, collaboration, communication, and integration are the key elements of incorporating DevOps into any development and delivery setting. Building multi-skilled teams which are made up of human talents (e.g., developers, sysadmins, and testers) can include great benefit, but without the ideal teamwork and attitude, the talent is virtually useless. If folks know they can depend on everyone else, the team as a whole also moves much more quickly and efficiently, ultimately resulting in happier customers.
The first step in a DevOps approach involves understanding how software development, IT operations, and QA are mutually dependent on each other. As mentioned above, DevOps relies on cross-departmental cooperation and open communication between the key players in the program delivery pipeline so as to improve operational efficiency, predictability, and maintainability. Integrating and automating these elements early in the process allows teams to stream program delivery.
DevOps is your Future of Enterprise IT
Modern-day enterprise applications are riddled with characteristics that keep growing from using different technologies, multiple databases, and various end-user apparatus, and DevOps might be the only viable method to cope with such diverse environments successfully.
