I'm Caique Baptista, Tech Lead DevOps Specialist, and today I'm going to tell you more about what DevOps is, its performance, benefits and how it works here at levva.
Amongst so much code, changes, creations and applications, how to make development and operations communicate better and be more efficient? With DevOps!
DevOps is a culture created by Google in the early 2000s with the goal of helping development and operations teams work together, with better communication. Before the creation of DevOps the delay for the delivery of a demand was very large precisely because of the lack of communication or constant failures between the areas.
This methodology was created to unify these sectors and be an agile culture, which seeks effective communication and a simpler process from the beginning to the end of the projects. This culture is basically based on three pillars: automation, collaboration, and measurement:
DevOps is an area that is independent from the development and operations areas. In this area, the team looks for the best way to unite the two areas. It is necessary to have knowledge in Cloud and applications. In the case of applications, it is also necessary to know how they need to be delivered.
The DevOps team does not need to know how to develop software, but should have a general knowledge of the software and infrastructure areas, knowing how each application will be used.
In practice, DevOps acts in projects as follows: when a specific demand to deliver an application arrives, the team understands the best way to apply this in a resilient, secure, and reusable way, looking for the technologies that are on the rise in the market.
Following these criteria, the best way to realize the applications is defined, making sure that the code the developer is building is delivered in a secure and usable environment.
No, DevOps can be used for services that are not in the Cloud as well, but nowadays in the market it is very difficult to find. Generally in banking operations or similar, Clouds are not used, but otherwise it is very unusual for companies not to use this technology.
The most most notable are increased productivity and a delivery agility. In addition, the digital environment tends to be very stable., hardlyfalling. This happens when workingr with best practices in DevOps, so that if the environment goes down, it can go up by itself.
To implement DevOps in your company, a few steps are necessary, but of course, they may vary according to your way of working. The main point needed is to work with an agile culture, in which you understand what your team's main communication difficulties are, analyzing how to automate these processes.
Check out the steps required to implement DevOps in your company:
1 - Perform an assessment of your company's maturity in relation to DevOps practices, this will help map out a starting point for implementation;
2 - Set up your DevOps team composed of software development, IT operations, and automation experts;
3 - Set clear goals, deadlines, and objectives for this new team;
4 - Adopt agile practices and ensure that the agile culture is understood and applied by everyone;
5 - Automate all possible processes to speed up software delivery and reduce downtime;
6 - Monitor and measure progress, it is very important to follow the progress of this team and ensure that the implementations are aligned with the company's goals;
7 - Make adjustments as needed to ensure long-term success.
When a new client arrives, the DevOps team is needed from the beginning of the project, understanding the contractor's pains and making it clear how the processes will work. DevOps can act within squads and often within the development team, to further optimize the processes.
Generally, at the beginning of a project, one seeks to understand the architecture that is being created in order to make the proper comments about the environment that is being developed. Then begins the implementation phase of the resources that will be used in that specific architecture.
Once that first step is done, all the provisioning is done at the code level, such as the infrastructure, and then the developers start to actually build the applications. Finally is the deploy part, which is the unification of what the DevOps engineers build and the application that was made.
A good example within levva is our client, Ambev, which uses exactly this working model. In this case, they pass the architecture and levva's DevOps team builds the environment. When Amebv has some new feature to be implemented, this is communicated and levva builds a new infrastructure to be able to support this new application. With this, they can publish the code and then the team can deploy it, putting the whole environment inside the Cloud.
Besides the demands to customers, some DevOps people also work with internal demands of the company. To control these demands, the company organizes itself through a board where employees can open calls with requests to the DevOps team. For example, when someone needs to upload an application that needs a pipeline to work, the internal team executes this creation.
In levva, it is DevOps that decides which service will be used in the Cloud, applying the necessary infrastructure so that it is used optimally with the code that the developer has made.
Besides achieving better results and the benefits already mentioned above, the major importance of DevOps is to ensure quality delivery with speed. This is only possible if the team is aligned. Within this sector, communication is fundamental and reflects directly on the final delivery.
There are some strands that go through DevOps on the security side, but this sector is not entirely focused on that. DevOps works together with the cyber security team to understand what possible breaches the architectures may have and fix them.
In the DevOps market, there is another kind of squad that is DevSecOps, a specific security team that does the communication between development, operations and security. This sector is more focused on the automation level for security processes.
It depends a lot on the context in which each company is inserted. A company that operates in the technology and development niche, if it doesn't have a team focused on DevOps culture, will have a delivery delay and a much lower capacity to keep up with the market. It will lag behind its competitors.
DevOps is a fundamental sector within startups, along with development, because besides increasing efficiency and delivery quality, it promotes collaboration and the evolution of the employees involved.
