1. Focus
The main focus of continuous integration is on automating the build and test process. This involves merging code changes made by different developers into a single branch on a regular basis, running automated tests to verify that the code is functioning correctly, and providing rapid feedback to developers if issues arise.

In contrast, continuous delivery extends the concept of CI to encompass the entire software release process. This includes not only building and testing the code but also automating deployment and release processes so that new features can be delivered quickly and reliably.

2. Timeframe
CI is typically performed on a daily or even hourly basis, with small incremental changes being integrated into the main code base frequently. This allows teams to identify and fix bugs quickly before they become more complex and difficult to address.

CD goes one step further by emphasizing frequent releases of working software in short time frames. The idea is to release software updates as soon as they are ready instead of waiting for a longer development cycle to be completed. This helps organizations deliver value to their customers more quickly and remain competitive in a fast-paced market.

3. Automation
Automation plays a crucial role in both CI and CD approaches, but it takes on even greater importance in CD where it becomes essential for achieving faster delivery cycles while maintaining quality standards.

In CD, automation expands to include deployment pipelines as well as release orchestration tools, which help automate manual tasks like deploying code updates to production servers or configuring infrastructure resources.

4. Deployment frequency
CI encourages teams to break down large chunks of work into smaller pieces that can be integrated on an ongoing basis without disrupting other team members’ work. As a result, code is typically deployed to production more frequently in CI than in traditional development models.

CD expands on this concept by striving for even more frequent deployments. Rather than having a set release schedule, CD advocates for smaller, incremental changes to be released as they become available.

5. Team structure and collaboration
CI requires strong collaboration and communication among development team members to ensure that code integrations occur smoothly and any issues are addressed quickly. This level of teamwork encourages developers to take greater responsibility for the quality of their code.

Similarly, CD relies on high levels of collaboration between teams involved in different stages of the software delivery process, especially between development and operations teams. By working closely together, these teams can identify bottlenecks in the delivery process and continuously improve efficiency and productivity.

In summary, while CI is an essential part of successfully implementing CD principles, CD takes a broader view of software delivery, encompassing not just the integration but also testing, deployment, and release processes. Ultimately, the goal of both approaches is to deliver high-quality software faster and with less risk.
