Continuous Integration (CI) and Continuous Delivery (CD) enables software developers to make code changes more frequently and reliably all the way to the customer. Its implementation is also known as the CI/CD pipeline. CI/CD is one of the best practices that can be implemented by development teams. The design of a CI/CD pipeline corresponds to an agile approach because the pipeline allows software development teams to focus on compliance, code quality and security when the deployment steps are automated.
What is Continuous Integration?
Continuous Integration causes development teams to implement small changes and check code into version control repositories more frequently. Since most modern applications require code to be developed on different platforms and tools, the team needs a mechanism to integrate and test all changes, and the technical goal of CI is to provide a consistent and automated way to build, deploy, and test applications. If the integration process is consistent, it is easier for developers to make code changes, resulting in better collaboration and quality of the software.
What is Continuous Delivery?
Continuous Delivery continues where Continuous Integration stops. CD automates the deployment of applications in selected environments. Most teams work with more environments than the production environment, such as development and test environments, and CD ensures that new code is automatically transferred to these environments.
CI/CD tools help ensure the environment-specific parameters that may vary with each delivery of software. CI/CD Automation then makes all necessary calls to the web server, databases and other services that may need to be restarted or execute other commands during deployment.
What Are the Advantages of CI/CD?
Continuous Integration and Continuous Delivery provide the perfect playground for Continuous Testing (CT), as the goal is to deliver high quality applications and code to users. Continuous testing is often implemented as a series of automated regression, performance and other tests executed in the CI/CD pipeline.
Automated testing frameworks help quality assurance managers define, execute, and automate various tests that help development teams determine whether a software build was successful or not. These include functionality tests that are developed at the end of each sprint and aggregated into a regression testing
for the entire application. These regression tests then inform the team whether a change in the code has failed one or more of the developed tests. Regression testing is only the beginning. Performance testing, API testing, static code analysis, security testing, and other test forms can also be automated. The key factor is that these tests can be triggered from either the command line, Webhook, or Web service, and that status codes are used to respond with status codes for the successful or failed test.
Once testing is automated, Continuous Testing implies that automation is integrated into the CI/CD pipeline. Some unit and functional tests
can be integrated into the CI Pipeline to indicate problems before or during the integration process. Tests that require a complete production environment, such as performance and security tests
, are often integrated into the CD and performed after delivery.

What Are the Advantages of Automated CI/CD Pipelines?
The Forresters Global DevOps Benchmark Online Survey of 2017 found that over 50% of respondents had already implemented DevOps and were planning to deepen it, but over 64% reported that they were dissatisfied with "the time it takes to release new features to customers". The key here is that only 34% of them have achieved complete and end-to-end automation from development to the production environment, and in these days of agile software development, automation has proven to be essential for the continuous integration and delivery of software.
Sub-processes can be defined in so-called pipelines to perform recurring tasks that should have been performed manually, thus blocking valuable development capacity. Current tools such as Jenkins, Travis CI, Bamboo or JetBrains TeamCity make it possible to define special processes as pipelines in a programmable and declarative manner and to have them executed automatically under certain conditions.
A quick online search for a DevOps automation solution results in hundreds of developer tools and complete pipeline executions. The strengths and core competencies of each tool are different, as are the needs of each company. Regardless of the number of tools, companies should not neglect the choice of pipeline automation tools that are tailored to their specific environment. As experienced experts in pipeline automation, we can take this step for you and take away the associated uncertainties - so that your company remains competitive and doesn't miss the boat.
