Automate build, test and deployment processes<
In the new age of mobility and digital transformation, enterprises need to move faster and more flexibly in application development, testing and QA to keep up with the competition and meet customer expectations for shorter cycle times and higher service levels.
This requires integrating the efforts of their development and QA teams and automating manual processes wherever possible.
Enterprises that make this shift effectively can improve employee productivity, open up new revenue channels, enhance customer service and engagement, and distinguish themselves from their competition – all while reducing their operational costs in development and QA.
Companies that can’t make the shift face increasing costs, customer dissatisfaction, disintermediation, revenue loss and more. Continuous Integration (CI) and Continuous Delivery (CD) are foundational practices being adopted by agile organizations to accelerate their development and test processes to meet the new demands of mobile and IoT. While they are distinct disciplines, most organizations find the greatest impact by adopting them together.
The benefits of this approach include reduced time, risk, and expense of software delivery. This paper looks at the benefits of CI and CD together and the requirements for effectively deploying these practices in your organization.
QA vs. QE – What’s the big difference?
Continuous Integration and Delivery (CI/CD) is a set of software practices and techniques that enable the frequent release of small batches of code changes, with extensive visibility and traceability. It typically involves the creation of a largely automated pipeline that orchestrates the build, test and deployment of software across staged environments, ultimately leading to deployment in production.
CI/CD allows an elegant way to establish the appropriate quality gates in the development and testing process. A fast feedback loop to the developers ensures that bugs are addressed early in the development cycle.
Finding a bug at the development stage is the cheapest possible way to find it. If the same bug was to be fixed in any other environment, it would cost more. CI/CD requires some upfront overhead cost, but these are more than offset by the time and expense saved along the way.
CI/CD enables QA teams to release deployable software at any point in time. Without it, projects are prone to delayed releases because of unforeseen issues which arise at any point in the traditional development and test process.
Frequent code integration provides the opportunity to identify trends in build success and failure and make informed decisions to address them. With CI/CD, dev and test teams can access real-time data on the code quality metrics to innovate new improvements and support decisions.
CI/CD replaces testing assumptions with knowledge, thereby eliminating all cross-platform errors at the development stage.
Faster test and QA cycles enable organizations to get quality products and services to market faster and more efficiently.
By establishing continuous testing into the automated integration process, software health attributes such as complexity can be tracked over time.

It typically involves the creation of a largely automated pipeline that orchestrates the build, test and deployment of software across staged environments, ultimately leading to deployment in production.
CI/CD may have more potential impact on mobile and IoT than any other area of development and test due to the non-stop pressure organizations face to crank out new apps and services.
Without CI/CD, dev test organizations face a number of obstacles:
This enables businesses to:
Respond more quickly to market dynamic and get new products and features to market faster
Get more impact from mobile initiatives
Accelerate their level of innovation
Save time and money
Provide higher reliability
Need to built a platform that lets us create a CD pipeline for each application
Research is needed on understanding their characteristics and identifying and developing the best strategies or practices to tackle them
Continuous delivery (CD) means stitching together a tool chain spanning multiple vendor and open source tools
In order to meet your throughput and consistency goals, it is usually required to automate a bulk of the manual steps in the process
Plan to be running delivery pipelines at scale, a dynamic pool of available, “clean” target environments is required
Align the organization to understand, adopt, engage and leverage CD and management willingness to “do things right”
Key decision makers and cross functional teams lack unified visibility in an enterprise SDLC dashboard
There are a plethora of tools that can add value to your CI/CD initiative, but picking the right one and getting them working together requires time, good planning and specialized expertise.
By the nature of the problem it is addressing, CI/CD is a cross-functional effort spanning the entire software development lifecycle. As such, organizations may find themselves creating roles that require a hybrid set of skills that may fall outside of traditional development, test and QA job descriptions.
As a result, it’s important to define roles and responsibilities clearly to avoid confusion and accountability gaps.
There are several best practices that have been proven by early adopters in recent years that can guide your CI/CD initiative.
These involve incorporating sound design principles for your overall approach, creating a management dashboard to provide the cross-functional visibility that is so critical to success, and selecting the right infrastructure tools to accelerate your CI/CD initiative.
| Principle | Description | Rationale |
|---|---|---|
| Self-service | Projects must be able to on-board through self-service, and manage their own workflows. | Speed to adoption: Key driver for rapid experimentation, and to eliminate duplicated efforts and manual process. |
| Best-practice | Support a standard workflow model, not a generic workflow engine. | One Standard. Promotes quality, fast on-boarding and developer mobility. |
| Configurable Technology integration | The ability to integrate existing build systems, test frameworks, and source- and component repositories, still recommended templates for new projects. | Separation of concern, Continuity. Allow projects to on-board to CI/CD independently of transition legacy systems. |
| Flexible Process | Ability to adapt workflow to match requirements for process variations. | Separation of concern, Continuity. There are both technical and business reasons for process variation. We cannot enforce a strict. |
| Extensible | Use a component-based automation framework, with consistent design patterns for task-automation, resource management, and identity. Build as internal open source. | Best-of-breed, Inclusion, Innovation. The system must allow a project to automate special tasks (e.g. run a specific analysis or verification tool), including experimentation with new and emerging technologies. |
| Cloud-Ready/Elastic | Build for deployment to AWS, or any other cloud to the extent possible. | Cloud Ready. Build and testing generates uneven load, and we can leverage cloud elasticity. |
| HA/DR | CI/CD must make suitable use of runtime services, including monitoring, to ensure availability, and respect of SLAs. | Fidelity. It’s important that the system be designed to handle adversity. Workflows must be suitably isolated to avoid general system failures. |
As referenced above, there are a number of tools out there supporting different aspects of CI/CD, but Jenkins has proven to be the best software platform for CI/CD.
Fortunately, most development organizations are already using open source Jenkins in some capacity today and comfortable with it. As with any critical piece of infrastructure software, organizations typically need the enterprise-grade features, reliability and deployment expertise to take full advantage of it and minimize the risk to your organization. This is especially true with CI/CD.
CloudBees, the enterprise Jenkins company, is a proven entity in CI/CD. CloudBees provides solutions that enable DevOps teams to respond more rapidly to the software delivery needs of the business. Building on the strength of Jenkins, the CloudBees Jenkins Platform provides a wide range of CI/CD solutions that meet the unique security, scalability and manageability needs of enterprises. The CloudBees Jenkins Platform supports many of the world’s largest and most business-critical deployments.
