A methodology for your digital transition: DevOps

You need to complete your digital transition as quickly as possible, and this requires the creation and use of a functional, customised software with many possibilities for a rapid evolution.

In order to meet your needs, Tana Corp applies the DevOps method, which guarantees you an accompaniment in the technological evolutions related to your line of business, and a fast delivery of your software, in the respect of the deadlines. This speed of execution is linked to short development cycles, with particular attention paid to quality through continuous testing.

The DevOps methodology, just like the SCRUM method that we also apply, is an agile method, which provides a framework for rapid and rigorous development, while remaining flexible and respecting common progress rules.

It is characterized by :

 

  • Shorter development cycles, so that your software is delivered in the shortest possible time
  • early and continuous testing to ensure the quality and reliability of our products a short improvement loop, to ensure fast user feedback
  • An increase in the frequency of deployments, in order to make your software evolve according to your feedback, your needs and those of your industry
  • in order to achieve the objectives we have set together for the realization of your project.

 

 

This iterative approach allows you to remain at the heart of your project, the speed of the cycles ensuring you a regular piloting and evolutions as close as possible to your needs

 

DevOps: principles and benefits

Définition

The term DevOps, attributed to Patrick Debois in 2009 during a conference, comes from: developer (Build) and operations (Run)

It represents the two main functions of IS management, which, although complementary, have very different objectives:

  • For software development (dev): the goal is productivity, the response to customer needs by designing and developing software within the given deadlines, sometimes at the expense of quality.
  • For operations administration (ops): the goal is system stability, quality control, software reliability sometimes at the expense of cost and time constraints.

The DevOps culture and mindset is to improve, or even recreate communication between these previously separate teams, so that they work together to improve practices and the quality of service offered to clients. Thus, the fields of competence are widening and the roles hitherto assigned to each team are tending to redefine themselves.

The DevOps methodology aims to globalize agile methods to the entire IS and to apply the principles of agility to production.

Although there is no official definition of this term, we can quote the definition in the State of DevOps Report 2017 :

“Today, DevOps is an understandable set of practices and values that have proven, for companies of all sizes, their effectiveness in improving: software delivery cycles, software quality, security, and the ability to get customers back on the product quickly”.

Principles

  • Automation of the various tasks (development, tests, etc.) for time optimization and quality improvement.
  • Use of measurement tools and indicators to monitor processes and quickly find flaws or points for improvement
  • Shorter development cycles and increased deployment frequencies
  • Early and continuous testing
  • Continuous deliveries
  • A short improvement loop to improve user feedback
  • Better communication and collaboration between departments

These practices are designed to improve productivity without compromising quality, and help improve the company’s performance in achieving its objectives.

Benefits

The DevOps method responds to the need of companies to have the best possible production lead times, while having a clearer vision of the forecasts.

The improvement of quality is also an essential point, the delivered software is thus more reliable and secure, with the possibility of having rapid and numerous evolutions.

Furthermore, speed of execution, application monitoring and quality improvement are all sources of cost reduction for the company.

In conclusion, if you wish to start up, in addition to a methodology, DevOps is above all a state of mind and a corporate culture to acquire, which requires the involvement of everyone and the support of your organization before you can reap the benefits.
