Numerous companies have successfully increased their deployment frequency without compromising quality, thanks to continuous integration, delivery, and deployment (CI/CD) practices. With a CI/CD workflow, updates can be rolled out monthly, daily, or even hourly. While many companies primarily aim for efficiency gains and economic benefits, it's essential to underscore that the business advantages of CI/CD go well beyond the basics.

Incorporating DevOps practices enables businesses to decrease the time allocated to managing support cases by 60%, presenting a promising prospect for organizations considering DevOps adoption in 2024. Source

What is DevOps

DevOps, as its name implies, merges Development with Operations. It brings together individuals, procedures, and technology in application planning, development, delivery, and operation.

DevOps facilitates collaboration and coordination among traditionally separate roles such as development, IT operations, quality engineering, and security. It fosters a mindset of communication and collaboration among teams and stakeholders within an organization.

Understanding DevOps Applications

The traditional segregation between development and operations teams is dissolved within a DevOps framework. Often, these teams are integrated into a single entity, wherein engineers engage in various aspects of the application lifecycle, spanning development, testing, deployment, and operations. This integration cultivates a diverse skill set among team members, transcending the confines of individual roles.

In certain DevOps frameworks, quality assurance and security teams may also undergo closer integration with development and operations throughout the application lifecycle. When security becomes a collective focus within a DevOps team, this approach is called DevSecOps. Hire devsecops consulting services for teams to adopt practices geared towards automating historically manual and sluggish processes. They leverage a technology stack and toolset that facilitates rapid and dependable application operation and evolution. These tools empower engineers to independently execute tasks, such as deploying code or provisioning infrastructure, which traditionally necessitated assistance from other teams. This autonomy further augments the team's efficiency.

What is CI/CD?

CI/CD is a component of DevOps that integrates the principles of continuous integration and continuous delivery. It streamlines or automates many of the manual processes typically required to transition new code from a commit to production. This includes stages such as building, testing (including integration tests, unit tests, and regression tests), deployment, and provisioning infrastructure.

What is a CI/CD pipeline?

A CI/CD pipeline is a structured workflow that guides software development through phases of building, testing, and deploying code, encompassing Continuous Integration/Continuous Delivery practices. By automating this process, the aim is to reduce human error and maintain consistency in how software is released. Components within the pipeline may include compiling code, running unit tests, performing code analysis, ensuring security measures, and generating binaries.

CI/CD serves as the foundation of a DevOps approach, facilitating collaboration between developers and IT operations teams in software deployment. As customized applications increasingly define a company's competitive edge, the speed at which code is released has emerged as a critical competitive advantage.

Building Blocks of CI/CD Pipeline

CI/CD systems are highly customizable, tailored to the unique needs and workflows of each company. Specific steps within these systems may vary based on the programming languages and frameworks employed. Nonetheless, there are several fundamental components present in virtually every CI/CD pipeline. Let's explore them.

Build

The build phase typically initiates the entire pipeline. When a developer pushes code to a repository, the CI/CD build phase is activated, and the specific outcomes of the build phase may vary depending on the languages and technologies utilized. However, the successful execution of the build phase should culminate in the creation of a new software release.

Test

The testing phase may occur multiple times throughout the pipeline. Different sets of tests can be executed at various stages, both at the outset and conclusion of the pipeline. Following the initial build phase, it's typical to conduct unit tests on the newly generated software release to ascertain its functionality. Subsequently, additional testing phases, such as integration tests, may be carried out later in the process. In fact, the Testing phase can be executed after each subsequent phase in the pipeline.

It's important to note that one of the primary objectives of CI/CD is to detect issues as early as possible. Therefore, rather than conducting a single comprehensive test phase at the pipeline's conclusion, it's preferable to logically partition tests into smaller phases. For instance, if unit tests are failing, there's no need to proceed with integration tests.

Deployment

The deployment phase may also occur multiple times within a single pipeline. Initially, deployment to a development environment may occur separately from staging and production environments. It's customary to conduct preliminary tests before deploying to a staging environment, followed by additional testing before deployment to production.

Why CI/CD Pipeline is essential?

CI/CD pipelines represent automated processes enabling businesses to swiftly and reliably build, test, and deploy software. Leveraging cloud infrastructure provides a flexible and scalable platform for executing these processes, empowering businesses to adapt to evolving demands and optimize resource allocation. Together, these tools facilitate greater business agility through various means:

  1. Accelerated time to market: CI/CD pipelines, alongside cloud infrastructure, expedite the deployment of software updates and new features, thereby reducing time to market. This agility enables businesses to promptly address shifting customer needs, market dynamics, and emerging technologies.
  2. Enhanced quality: Automated testing and deployment mechanisms ensure thorough examination of software updates, minimizing defects and enhancing overall quality. This, in turn, mitigates the risk of downtime, particularly crucial in swiftly evolving markets.
  3. Increased flexibility: Cloud infrastructure furnishes a versatile environment for running CI/CD pipelines, enabling businesses to seamlessly scale resources according to demand fluctuations. This adaptability optimizes resource utilization and supports agile responses to market changes.
  4. Facilitated innovation: CI/CD pipelines, coupled with cloud infrastructure, facilitate swift and efficient experimentation with new ideas and technologies. This streamlined process reduces the risk of failure and expedites the introduction of novel products and services, affording businesses a competitive edge.
  5. Enhanced collaboration: CI/CD pipelines and cloud infrastructure foster collaborative efforts among development, testing, and operations teams, particularly valuable in rapidly evolving markets. By bolstering teamwork, these tools enable quicker responses to evolving demands and expedite the delivery of software updates.

Pipeline Concept with Jenkins

Jenkins Pipeline, often referred to as simply "Pipeline," is a collection of plugins designed to facilitate the creation and integration of continuous delivery pipelines within Jenkins. A continuous delivery pipeline automates the process of delivering software from version control all the way to end-users and customers.

Jenkins Pipeline offers a versatile toolkit for modelling delivery pipelines of varying complexity using code. Typically, the definition of a Jenkins Pipeline is written into a text file, known as a Jenkinsfile, which is then stored in the project's source control repository.

To swiftly begin using Pipeline:

  1. Install the Docker Pipeline plugin via the Manage Jenkins > Plugins page.
  2. Once the plugin is installed, restart Jenkins to activate it.
  3. Copy one of the examples provided below into your repository and save it as Jenkinsfile.
  4. Click the New Item menu within Jenkins
  5. Assign a name for your new item (e.g., My-Pipeline) and opt for Multibranch Pipeline.
  6. Select the Add Source button, designate the repository type you intend to utilize, and complete the required details.
  7. Finally, click on the Save button to initiate your first Pipeline run.

You might have to adjust one of the sample Jenkinsfiles to ensure compatibility with your project. Once your Pipeline is configured, Jenkins will autonomously identify any newly created branches or pull requests within your repository and commence executing Pipelines for them.

Conclusion:

Continuous Integration (CI) and Continuous Deployment (CD) represent significant transformations for development teams.
