What is continuous delivery?

Continuous delivery represents the capability to safely and swiftly introduce various changes, such as new features, configuration adjustments, bug fixes, and experiments, into production or the hands of users sustainably.
Our objective is to make deployments for large-scale distributed systems, intricate production environments, embedded systems, or applications predictable and routine processes that can be executed on demand.
This is achieved by maintaining our code in a perpetually deployable state, even amidst daily changes by large development teams. This approach eliminates traditional phases like integration, testing, and hardening that typically follow “dev complete,” along with the need for code freezes.
Why choose continuous delivery?

There is a common assumption that increasing software deployment frequency comes at the cost of stability and reliability. However, peer-reviewed research proves otherwise—high-performance teams consistently deliver faster and more reliably, even in regulated domains like finance and government. This offers a significant competitive advantage for organizations willing to invest in continuous delivery efforts.
Continuous delivery brings several key benefits:
- Low-Risk Releases: The primary aim is to make software deployments painless, low-risk events, achievable at any time. Techniques like blue-green deployments allow for zero-downtime deployments that go unnoticed by users.
- Faster Time to Market: Automation of build, deployment, environment provisioning, and regression testing processes eliminates the lengthy phases in traditional software delivery lifecycles. Developers can incorporate integration and regression testing into their daily work, avoiding extensive rework.
- Higher Quality: Automated tools detecting regressions within minutes free up teams to focus on user research and higher-level testing activities. Building a deployment pipeline enables continuous performance, security, and usability testing, ensuring quality from the start.
- Lower Costs: Investment in automation reduces the fixed costs associated with the release process, substantially lowering the cost of making and delivering incremental changes to software over its lifetime.
- Better Products: Continuous delivery supports working in small batches and obtaining user feedback throughout the delivery lifecycle. Techniques like A/B testing allow a hypothesis-driven approach, avoiding the development of features that provide minimal or negative value.
- Happier Teams: Research indicates continuous delivery minimizes release-related pain and reduces team burnout. Frequent releases enable active engagement with users, learning from their feedback, and focusing on delighting users by eliminating low-value, painful activities associated with software delivery.
Continuous delivery is not a magical solution, but a journey of continuous improvement. It involves the constant discipline of pursuing higher performance through the heuristic “if it hurts, do it more often, and bring the pain forward.”
How does continuous delivery actually work?
Let’s dive a bit deeper into the workings of continuous delivery. Picture it as a streamlined journey with a notable checkpoint just before the final release—a manual gate where human intervention is possible. Some checkpoints may spark debates, while others serve distinct purposes.
Take, for instance, the business team utilizing this checkpoint for critical last-minute release decisions. The engineering team ensures a polished version of the product is ready after each sprint, and it’s up to the business team to greenlight its release to everyone, a specific group, or individuals in a designated location.
The structure of this continuous delivery process hinges on the design of the product in play. If the product’s architecture is tightly woven, the process might appear intricate. The architectural design also shapes the various stages of the process and the artifacts generated at each step.
Initially, the process focuses on building components—these are the smallest, testable building blocks. Think of it as constructing a library, which serves as an example of a component. Moving forward, there’s the subsystem phase, where these building blocks come together to form deployable and testable units, such as servers or microservices.
Finally, if the need arises to release the entire system as a unified entity, the process seamlessly assembles all components in the system phase. This breakdown showcases the complexity and adaptability of continuous delivery to various product architectures and release scenarios.
Who should engage in continuous delivery, and when?

The answer is clear: the best time to embrace continuous delivery was yesterday. For teams looking to integrate this approach seamlessly into their workflow, a crucial aspect is having a single prioritized backlog.
This backlog should not treat continuous delivery as an afterthought but rather as a central element. The user story acceptance criteria should explicitly highlight automated software delivery methods, distinguishing them from manual processes. Additionally, the Sprint Definition of Done (DoD) should prohibit teams from concluding sprints with manual product shipments.
Implementing continuous delivery is not just a good practice; it’s the right thing to do. Occasionally, it requires champions to initiate the transformation. When set up correctly, continuous delivery pipelines become a self-sustaining investment.
Now, who should be involved in this process? While some organizations assign the task to less experienced individuals, they quickly learn the intricacies involved. Appointing junior members may convey a low priority for continuous delivery.
Therefore, we strongly recommend placing a senior architect in charge—someone with a profound understanding of both technology and business. This ensures a strategic and well-informed approach to the implementation of continuous delivery pipelines.
Continuous Delivery Principles
The principles of Continuous Delivery guide teams in adopting a streamlined and efficient approach to software development and deployment.
Automation Everywhere:
At the core of Continuous Delivery is the principle of automation. Automation extends across the entire software delivery lifecycle, from code integration and testing to deployment and infrastructure management. By automating repetitive and error-prone tasks, teams can achieve faster and more reliable software delivery. Continuous Integration (CI) tools, automated testing frameworks, and deployment pipelines play key roles in implementing this principle.
Automation ensures that every code change is rigorously tested, eliminating the risk of manual errors and inconsistencies. Continuous Integration tools, such as Jenkins or GitLab CI, automatically build and test code changes whenever they are pushed to the version control system. This rapid feedback loop allows teams to catch and rectify issues early in the development process, reducing the overall cost of fixing defects.
Build Quality in:
Continuous delivery promotes the idea of building quality into the development process from the outset. Instead of relying on manual testing as the final gate, teams integrate automated testing at every stage of the pipeline. Automated tests, including unit tests, integration tests, and end-to-end tests, serve as a safety net, ensuring that each code change meets the required quality standards.
Test-driven development (TDD) is a key practice aligned with this principle. Developers write tests before writing the actual code, ensuring that the code meets the specified requirements. This proactive approach to quality significantly reduces the likelihood of defects reaching production, resulting in more stable and reliable software.
Work in small batches:
Working in small, manageable batches is a fundamental principle of continuous delivery. Breaking down work into smaller increments allows for faster and more frequent releases. Small batches facilitate quicker testing, deployment, and validation, reducing the time it takes to get valuable features into the hands of users.
The concept of small batches extends beyond code changes to include all aspects of software delivery, such as infrastructure updates and configuration changes. This principle encourages a continuous flow of small, incremental improvements, minimizing the risk associated with large, complex changes.
Relentlessly pursue continuous improvement:
Continuous delivery emphasizes a culture of continuous improvement. Teams are encouraged to regularly reflect on their processes, identify bottlenecks, and implement enhancements. This principle aligns with the idea of Kaizen, a Japanese philosophy of continuous improvement.
Metrics and analytics play a crucial role in pursuing continuous improvement. Teams track key performance indicators (KPIs) related to the software delivery process, such as lead time, deployment frequency, and change failure rate. Analyzing these metrics provides insights into areas that require attention, enabling teams to make data-driven decisions and continually refine their delivery pipeline.
Automate and decouple deployment from release:
The final principle of continuous delivery focuses on decoupling deployment from release. In traditional development models, deployment and release were often intertwined, making rollbacks challenging and risky. Continuous delivery separates these processes, allowing for more controlled and reversible deployments.
By decoupling deployment from release, teams can deploy new features to production but choose when to make them available to users. This enables feature toggles, gradual rollouts, and A/B testing, providing teams with the flexibility to assess the impact of changes and respond accordingly. This principle enhances the overall reliability and resilience of the software delivery process.
Continuous delivery is a transformative approach that empowers development teams to deliver software faster, with higher quality and improved reliability. The five principles—Automation Everywhere, Build Quality In, Work in Small Batches, Relentlessly Pursue Continuous Improvement, and Automate and Decouple Deployment from Release—guide organizations in establishing a culture of continuous improvement and innovation.
