CI / CD - Quality, speed, high-performance

The first step in modernizing your company’s development sector is understanding that gaps must be eliminated. Bringing development sectors closer to operations, in a DevOps culture, guarantees a more efficient execution of each application. The question is: what is the practical translation of this? One of the answers may be CI / CD – continuous integration (CI) and continuous delivery (CD).

The term refers to a set of operating principles and practices that enable the development team to deliver changes to an application’s code in a more flexible way.

That is, more frequently and reliably in the result, making the whole process more dynamic.

This practice also has many values of agile methodology. After all, by relying on automated deployment steps, the strategic potential of the development team is all about meeting business requirements, such as code security and quality.

CI / CD: A definition

For those who are not familiar with the term, it is good to understand that CI / CD is seen in the world of development as a pipeline. The objective is to achieve continuous delivery through a high level of automation, with constant monitoring of the development stage.

Continuous Integration – Continuous Integration

First part of this pipeline is the Continuous Integration process. That is, every time a developer sends new code (such as minor changes) to the application, it automatically compiles and tests the solution – as many times as necessary, regardless of the platform or language.

With the current type of development, in which a variety of platforms and tools are needed, this practice is a real “hand on the wheel”.

After all, it is in charge of integrating and validating changes automatically, without the need for manual and individualized action.

With this, your company consolidates the processes of creating, compiling and testing applications. This flexibility allows greater freedom and collaboration when improving the code, which increases the final quality of the solution.

Continuous Delivery – Continuous Delivery

The continuous delivery process begins just where continuous integration ends.

In other words, the CD is responsible for automating the delivery of applications to selected infrastructure environments. In other words, once the new code is validated in the integration tests, the CD automates its submission to the right repository.

This is particularly necessary, as in the development of an application, it is common for teams to work with several different environments and layers (such as testing, development, etc.).

That way, you have a code base prepared for deployment in any productive environment.

The CD process ensures that code changes reach the right place.


To put the pieces together: Continuous integration is the process behind automating tests and validating code changes. Continuous delivery is the process of automating the delivery of these changes to the code infrastructure, among other additional processes.

How does the CI / CD process work?

On practical issues, there are several tools used to automate the CI / CD. It all depends on your scope of work.

Among the main ones, Jenkins, AWS CodeBuild and Azure DevOps stand out, which automate the necessary steps and provide the data for continuous monitoring.

The tool can also report failures in the delivery process in real time, allowing developers to make quick decisions.

In addition, it is common to find teams operating the CI / CD pipeline on serverless architectures, such as cloud environments. With this, they use container technology and orchestration systems, such as Kubernetes.

Thus, it is possible to adopt a microservice approach to application development, making the entire operational step more agile and in accordance with the customer’s needs.

How to measure the impacts of CI / CD?

As with most modern methodologies, it is possible to measure the efficiency of your applications using KPI’s – the key performance indicators of DevOps.

Among the main ones, we highlight:

Deployment frequency;
Delivery time of the change;
Average recovery time (MTTR) for an incident.
It is common to observe significant changes in the data related to these indicators in a company that implements CI / CD in its development culture.

CI / CD: Good practice of DevOps culture

DevOps is a modern and necessary approach for companies looking to align their application development process. Before you even implement the DevOps methodology in your company, it is essential to understand that it is based on clear communication above all. Thus, with transparency and the integration of the development and operations teams, it is possible to optimize all delivery.

However, how to put all this into practice in the workplace? CI / CD is the answer. And it is not just us who claim. According to experts, this is one of the 5 best practices for DevOps.

CI / CD is perfect for companies looking to align the development process. Through it and its tools, it is possible to continuously send changes to applications that need stability, without compromising their performance.

That is, for developers, it means greater flexibility and freedom to act on necessary changes.

And for the operation team, the application remains stable because the environments have standardized configurations and separate variables. In addition, there are ongoing tests in the delivery process and reversal procedures are automated by the platform.

In other words, teams can focus on improving applications, while the CD / CI software itself takes care of the technical details of the system.

In this way, CI / CD enables your company to improve its own applications and solutions in general, while also optimizing the delivery process.

Therefore, there is no doubt that the integration of CI / CD with the DevOps culture can bring countless benefits to your business.

With the collaboration of both teams (development and operations) on technological, practical and strategic issues, it is possible to align your creative process with modern practices. With the support of automation resources, the teams focus on what really matters: the customer’s needs.

In the corporate day-to-day, this translates into better quality work and reliable deliveries, which promotes the company’s growth.
