CD and CI can be tough to decipher for a non-technical crowd. So, let’s start with an example.
Let’s say you’re driving a high-speed vehicle, and suddenly you realize there’s something wrong with the engine and you must make some changes. But to do that, you need to stop and open the hood. This sounds very inefficient if you are in a hurry, right?
Engineers face a similar challenge when they are working with software or solutions that are performing but can use some iterations. This is where CD and CI come in. A well-planned and executed CI/CD strategy is all about building systems that are faster, safer, and more scalable while enhancing collaboration across teams.
In this blog, API Connects – a leading provider of Mulesoft integration services in NZ – will share insights on:
- How to set up CI and CD processes in a modern technology landscape?
- What tools are the best for CI/CD?
- Why should you invest in the CI and CD process?
Let’s break it down.
Why CI/CD Matters?
With growing technology expectations, the need to keep systems fast is paramount, and manual processes can simply not keep up. Here’s why CI/CD is a must if you want to boost performance and retain customers in the long run:
Faster time to market: In today’s competitive world, speed of deployment is of great importance. CI/CD ensures that developers integrate and deliver code far more quickly, significantly reducing the time from ideation to deployment.
Reduced Risk: CI/CD mainly focuses on continuous testing which means bugs are caught pretty early. This also means there is less chance of surprises in changes being pushed to production.
Scalability and Flexibility: As applications grow in size and become more complex, a good CI/CD pipeline can ensure that systems will scale yet remain reliable.
Customer Satisfaction: The end-users get faster deployments with higher quality software, enhanced customer experience, and thereby improved customer retention.
Less Backlog and Defects: The time cycle efficiency of CI/CD leaves more time for the developers to clean out the legacy code and fix defects of all shapes and sizes, thus improving the quality of code.
Metrics Monitoring: As CI/CD pipelines work 24/7, teams get constant performance data analysis in advance, allowing them to detect issues before the user is impacted, and thus assure high-quality releases.
Time and Money Savings: CI/CD automation encompasses processes such as management, deployment, and testing to reduce the amount of manual labor at a cost. Automated testing is crucial as it will save the business from delays.
Fast Fail Identification: With CI/CD’s automated testing, developers can quickly spot issues and line up separate issues to resolve them, and that goes for more productivity and faster releases.
Easy Rollbacks: CI/CD pipelines provide the ease of rollbacks and make teams recover fast from problems without considerable downtime.
Continuous Feedback: Real-time insights from CI/CD pipelines give teams and stakeholders a clear view of development, helping catch and fix problems early.
Stages of CI and CD Deployment
The CI/CD pipeline consists of continuous integration, source, delivery, and deployment phases. It is mainly divided into 4 stages:
- Source
- Build
- Test
- Deploy
Each phase has to be finished before the next can commence. Simultaneously, they are systematically examined for potential errors and possible feedback is fed to the delivery team. Let’s look at them one by one:
Source: The source stage, also known as the version control stage, is responsible for managing and storing the source code in a versioning system like Git. Developers are able to push the code to the version control in order to detect any change that might have been made. GitFlow innovations and trunk-based development methodologies enable multiple teams to work together at the same time. This stage typically triggers the pipeline upon new commits or pull requests and may include initial quality checks like linting.
Build: The build stage is where the source code is turned into a product that you can run. For instance, Java code can be turned into bytecode and then bundled in a JAR or WAR file, or binary code can be turned into container images and run by Docker. Usually, the build phase involves dependency resolution, asset bundling, and unit testing. If the build or tests fail, the pipeline will come to a stop to make way for a quick issue resolution, following the ‘fail fast’ principle.
Test: In the test stage, the application is subjected to automated tests to check whether it satisfies all the requirements before it reaches the end-users. The following are common tests:
Integration tests: These are tests that check if the components can behave normally together in the entire system.
Functional tests: These tests are for testing the system as a black box or doing them in the form of the user interface to ensure that everything works as if it were seen from a formal user’s perspective.
Performance tests: These tests make sure that the application can handle the anticipated load, it is fast, and remains strong under stress.
Security tests: These tests are run to reveal potential security holes and risks in the application.
Deploy: In the final step, the constructed and verified application is sent to production, thus it becomes alive for users. The particular manner of deployment may encompass cloud platforms, Kubernetes clusters, or old-style servers. Deployment is fully automated, often followed by post-deployment tests to ensure everything runs smoothly in the live environment.

Best Practices for CI/CD Pipeline
A well-optimized pipeline not only streamlines development but also minimizes errors, enhances collaboration, and ensures consistent deployment processes. Here are some of the best practices to optimize the CI/CD pipeline.
Centralized Repository: Embrace a single version control system for all code, configurations, and documents to simplify the management and support collaboration.
Automate Everything: Automating steps of the process such as building, testing, deployment, and monitoring as much as possible will result in less human error, save time, and be more consistent in the long run.
Consistent Build Process: The building process should be the same condition locally and in the CI/CD pipeline. This erases the discrepancies and thus prevents the emergence of unexpected issues.
Parallelize Tasks: Implement the possibility of running tasks and tests concurrently in order to save time on the pipeline. Run tasks with logic so that dependencies are taken into account and execution in parallel is fast.
Use Build Artifacts: Storing build artifacts (e.g., binaries) in one place will help to deploy the applications fast and roll back to a previous version if needed.
Comprehensive Testing: Incorporate unit, integration, and end-to-end tests in the pipeline to ensure the application is thoroughly vetted before production.
Continuous Monitoring and Improvement: Monitor pipeline performance and gather feedback to identify bottlenecks. Continuously iterate to improve efficiency.
Encourage Collaboration: Foster communication and teamwork between development, QA, and operations teams to ensure alignment in delivering high-quality software.
By adopting these best practices, teams can significantly improve efficiency and reduce bottlenecks. No wonder, modern engineers are in love with CD/CIs!
