Especially today, in full digital transformation, DevOps methodology becomes, in the world of software development, the fast track to accelerate the speed and frequency of code releases, and, at the same time, maintain the fundamental quality and reliability requirements of the same.
Software, increasingly at the heart of business
In the digital age, software supports the business processes of any business, and is the basis of innovation and the development of new applications and services. In today’s increasingly intense competitive pressure on code release times and costs, maximizing the efficiency and effectiveness of the software development cycle (SDLC) through DevOps methodology thus becomes a categorical imperative for a growing number of business and industrial sectors. Even more so, however, adopting DevOps is even more strategic for companies whose primary activity is the production and distribution of software for different user categories: from companies adopting specialized applications in vertical sectors to consumers using mass-market apps.
Introduction to DevOps methodology
In the age of digital transformation, DevOps is establishing itself as a key methodology in software development. In contrast to the traditional ‘waterfall’ model, characterized by sequentiality and rigidity, DevOps introduces an iterative process that accelerates code delivery while maintaining high quality and reliability. This methodology effectively responds to the needs of a rapidly evolving market, supporting companies in the production and distribution of software and enabling them to agilely address competitive pressure on development time and costs.
Definition of DevOps
DevOps culture represents a paradigmantic evolution in the IT world, combining ‘development’ and ‘operations’ in a collaborative approach. By overcoming traditional “silo” of separate departments, it promotes efficiency and transparency in the development cycle. DevOps improves not only the speed of code release, but also the quality of the final product, quickly adapting to market needs and strengthening business agility.
DevOps Core Principles
DevOps principles –continuous integration, continuous delivery, collaboration, agility, and automation– enable organizations to accelerate the release of digital products while maintaining quality and stability. This collaboration-focused approach increases efficiency and productivity, improving the ability to adapt to market changes and time-to-market constraints, making companies more agile and able to respond quickly to market and customer needs.
DevOps Methodology Compared to Model ‘Waterfall’
The DevOps methodology aims to innovate classic paradigms such as the ‘cascade’ process model (waterfall), in which the development phases (project feasibility, requirements analysis, design, implementation, testing, installation, maintenance) unfold in a strictly sequential and hierarchical manner: in waterfall it is not possible to modify the requirements and functionality of a program in progress, but only at the end of the work, during interactions with the project client. Errors and defects are therefore identified only at the end of the process, and then we need to start over again.
Evidently, the current complexity achieved by software, in terms of the number of lines of code, for reasons of time and cost, makes this approach increasingly less viable. DevOps, on the other hand, aims to accelerate the development cycle, on the one hand by automating, through specific tools and technologies, the phases of code design, testing and implementation (build, test, deployment). On the other hand, breaking the rigid sequentiality of the waterfall method, through the introduction of an iterative development mode that allows you to correct project requirements, errors, and code defects directly during the process.
The heart of the DevOps methodology
It is important to clarify that, to achieve real success, the DevOps methodology, acronym for ‘development and operations’, cannot be based solely on the mere adoption, in the IT organization, of a set of technological and practical tools aimed at accelerating the code development and release cycle. DevOps, above all, is built by transforming the work mindset of teams. The latter must overcome the traditional distinction between departments (“development” and “operations”), becoming “feature teams” determined to share common tools, methods, principles and responsibilities.
Benefits of adopting DevOps in the enterprise
Companies that focus on software development in particular can benefit significantly from a DevOps methodology adopted correctly in the work environment.
Here are some:
Better team collaboration
One of the key benefits of DevOps is the promotion of better collaboration between development and operations teams. Overcoming the traditional separation of departments, feature teams in a DevOps environment work together by sharing tools, methods, principles, and responsibilities. This close collaboration improves communication, reduces misunderstandings, and accelerates the development process, leading to more effective and efficient results.
Software release at a faster pace
DevOps significantly accelerates the pace of software release. By automating the design, testing, and implementation phases of code, DevOps enables companies to reduce development and release times, increasing the frequency with which digital products and applications are brought to market. This is particularly advantageous in a competitive environment where rapid release can be a key factor for success.
Faster troubleshooting
DevOps’ iterative approach allows you to identify and solve problems faster and more efficiently. With shorter development cycles and continuous feedback, teams can quickly detect and correct errors, reducing downtime and improving the quality of the final product. This problem-solving approach not only improves operational efficiency, but also increases customer satisfaction and trust in the company’s software products.
