What Is DevOps?
DevOps is one of the most mentioned terms in the current IT environment. It is usually associated with digital transformation strategies, and methodologies such as Continuous Delivery or agile development.
Much of the confusion comes from mixing DevOps with the necessary requirements or benefits gained from deploying DevOps. Without wishing to be excessively dogmatic about a term whose contour lines have not yet fully settled, we will at least try to shed some light on the concept.
DevOps is a response to the interdependence of software development and IT operations. Its goal is to help an organization produce faster, better quality products and services at a lower cost.
Companies with very frequent releases may require knowledge of DevOps. Flickr developed a DevOps system to meet a business requirement of ten daily deployments. These types of systems are known as continuous deployment or continuous delivery, and are often associated with lean startup methodologies. Work groups, professional associations and blogs use the term since 2009.
- DevOps is a methodology for creating software
- DevOps is based on the integration between software developers and systems administrators
- DevOps allows you to manufacture software faster, with higher quality, lower cost and a very high frequency of releases
DevOps in a hazy world:
DevOps is not in itself a culture, but it does require a strong cultural and organizational change for its implementation. A cultural shift towards collaboration, communication, and ultimately complete integration between the old (usually rabidly watertight) areas of development and systems.
This cultural change is so complicated to achieve in some organizations, which are many that identify it directly with DevOps, but remember: is a methodology of software development, and a change of culture is not in itself a way to develop software
The end of the “confusion” and the unidirectional model
One of the problems that tries to settle the movement DevOps is the call “wall of confusion”. It is the conflict that arises when the Development team makes the transfer of code to the Operations team, and this works in the testing and in the scripts for the pass to production. It is then when there are incidents that do not know who to attribute, if Development to deliver code developed with failures or to Operations to make a bad configuration. And while both teams are in agreement, the release date is getting closer and there is no time to do more trial-error.
In this situation each department looks after its interests (the first seeks a fluid and dynamic system in which to be able to add new functionalities, the second the stability above all) and have their own priorities and way of working, provoking in more than one Occasion frictions and lack of confidence between teams. Precisely DevOps comes on the scene to bring together the interests of both departments and create an environment of trust and cooperation through practices that foster a positive attitude towards failure and a collaborative, blameless culture in which information flows, Talent intensifies and the team feels committed. It contributes to communication and two-way work through activities in which developers and operations work closely, for example in testing and quality tasks.
In addition to the implications on People, DevOps is a change in Processes. DevOps goes beyond agile methodologies and is based on the so-called Lean methodology. I will address this issue in a separate post but as an advance, applying Lean principles to the DevOps lifecycle helps achieve objectives and minimize the risk of changes occurring in deliveries in a more precise and rigorous way, to give still More value to customers and to the business itself. Devops training talks about the implementation techniques of Devops Tools in the market.
At the technological level: the toolbox
In addition to this cultural transformation, involving people and processes, also entails an adaptation (to a greater or lesser extent according to the organization) at the technological level. And the selection of tools is key to ensure continuity in the integration and delivery of IT products and services. From leading technology products to open source alternatives or custom-built platforms, DevOps flexibility allows each organization to choose the tools that are best suited to use.
The important thing is to have an expert opinion that knows well the possibilities of each technology and define the most convenient in each case. This will smooth the process and minimize the efforts and possible risks of the integration without losing the focus of the project in achieving the goals set DevOps.
