DevOps is a set of practices that reduce the uncertainties for engineers and reduce the number of failures in software production. As a rule, they also reduce the time to market, the period from the idea to the delivery of the final product to customers, which allows you to quickly conduct business experiments.
How to start the DevOps transformation?
In short: we select the service from which we will start the process, identify those who are related to the service, build the Value Stream Map, create a temporary team that will deal with the transformation for the first time and set it a task. We repeat the cycle as many times as necessary.
DevOps is an approach that allows development and infrastructure teams to collaborate more effectively against these new software requirements. In the era of continuous delivery and the cloud, DevOps is an extension of agile methods and is inspired by other experiences, such as Lean Startup and Scrum. DevOps Consultants can be a great help in initiation the transformation of your organisation.

A Revolutionary concept
The DevOps approach is a new concept of application development and delivery of IT solutions. After its modest beginnings in the web development circles, its ever-increasing popularity has led to many big names in the industry now praising it. But what is it exactly and what is the impact on technologies?
What is DevOps?
DevOps is a movement, an approach that favors close collaboration between development (dev) and operations (ops) teams for any IT solution. Through this alignment, the goal is to improve the quality of work and the relationship between these two teams who each have their vision to achieve customer satisfaction by delivering new code on demand and maintain availability of services.
The concept originated at developer conferences that sought to understand and improve the organization’s performance. It was believed that the integration of teams through a change in work structure, processes and tools would respond to the new realities of the rapidly changing business world.
Specific Understanding of DevOps
More specifically, the DevOps approach seeks among other things to improve the efficiency and velocity of changes, as well as Agile methodologies, by proposing continuous deployments while maintaining the stability of the environments. This is achieved by automation in all aspects, such as tests and deployment scripts. Also, DevOps Consultants favour the fluid sharing of knowledge and source codes between the two teams to ensure the best functioning environments.
Importance of DevOps
The world is changing faster than we feel the changes taking place. Opportunities for business development are emerging, based on new information technologies, which we hear a lot about, but so far are not getting any returns. While competitors are successfully using machine learning, blockchain, big data and other trendy technologies, we are just starting to study them.
How is it different?
Everyone is talking about digital transformation, but few can explain what a modern enterprise is and how it differs fundamentally from ordinary companies. However, it’s already clear that simply instructing the IT manager to “learn and implement” is not enough – the company should have some new, yet incomprehensible abilities, including regularly and purposefully inventing and quickly launching new products on the market. How to achieve this with the existing structure of the IT department and the existing management processes? Your DevOps consultants can help you understand these dynamics systematically.
What is DevOps’ impact on technologies?
The arrival of a new approach is changing the way we use technology and DevOps is no exception. Server, network, and storage virtualization technologies are a prerequisite for undertaking the DevOps turnaround by creating work environments that enable automation. Several industry vendors have already adapted their technologies to DevOps, so it’s important to keep the infrastructure up-to-date to facilitate adoption.
Technology choices also need to consider the shared use of operational teams and the development of performance and monitoring tools to capture the quality and success of application deployments. In summary, good change management, both technological and organizational, will manage the impact on your technologies of the arrival of DevOps.
What is changing attitudes towards more DevOps?
DevOps responds to the need to accelerate production releases. Good communication and integration between the teams is essential for quick production. The release deadlines of new features are sometimes very tight, and developers are getting closer to the ops to know what can be done on their side to ensure a quick release when the version is stable.
How does technology support this DevOps transformation?
The DevOps relies mainly on automation. Today, if we had to give ourselves a DevOps rating, it would be 5/10. That to say that even with a good integration of automation there is still a big margin of progress to be true DevOps. DevOps must be able to offer frameworks to developers, give them solutions or tools so that they can build an application that is as close as possible to the deployment in production. Transferring the application from development to production must be done in a split second.
What are the challenges to progress on this subject?
It takes time, because even though we have automated many processes such as software installation, we need a higher level of automation. You need to create a frame of reference, and the tools to stop wasting time creating a load balancer or other infrastructure component that is needed recurrently. The goal is to be able to automate all the infrastructure from A to Z, and to allow the developer to deliver his code without intervention of the Ops, but relying on a set of good practices, controlled by the DevOps framework.
What is the next step in this evolution?
It’s about moving the framework to a higher level of automation by automating the entire implementation of the AWS infrastructure. This could be realized in a service portal that can deploy each component (load balancer, autoscaling, etc.) for development or production as needed. Another axis of improvement of our put in production: Docker and the containers. A Docker file is provided by a developer is like a package – we must be able to put it into production, but here we must put in place good practices and rules for building this Docker file.
