Continuous Delivery (CD) is the next step in the evolution of the software development process. It draws on Agile methodologies, but surpasses it. CD is changing the way software is delivered and opening up a whole range of benefits, ranging from greater adaptability to more reliable products to improved customer experiences.
Instead of deploying a large release once a year or once every few years, which results in time-intensive fixes, CD is about delivering smaller changes more frequently.
But what if CD means sacrificing quality for speed? Does it really CD lead to both higher responsiveness and higher reliability? Let’s find out if it really enables you to get better products to your customers more often.
CD is a methodology that focuses on smaller releases more often to avoid the issues and bugs that come with large, slow releases. CD can actually make your software development more agile and more able to react to changes. CD comes with quicker reaction times, less risk and more flexible release options. It also identifies inefficiencies and hidden costs.
Considering the rapid pace of technological innovation, and consumers’ rising expectations for quality products, it makes sense to evaluate and modernize software delivery processes to keep pace with these developments.
CD, which relies on automated testing in production environments, integrates Continuous Integration (CI) practices. CI is an essential component and first step in the CD pipeline. CI has every developer continually integrate with all other developers.
A CD methodology continuously tests, analyzes and improves software quality. Importantly, this happens during all phases of the development lifecycle, instead of Agile’s approach of waiting until the end. Similarly, it also involves testing and Quality Assurance throughout the process.
When CD is well executed, it gives organization a vast number of benefits:
Much more than just combining development and operations, DevOps is a set of practices aimed at breaking down silos. BizDevOps is the next phase: it adds in business teams for further integration. CD therefore is a natural complement to BizDevOps.
One of the benefits of DevOps is its use of CD. But for CD to be effective, it needs to be adopted beyond just the development and operations teams. High-performing companies adopt CD practices across all products and services.
Unlike continuous deployment, which deploys each change into production on a very frequent schedule, CD ensures that the software is deployable at any point during its lifecycle.
You can deploy to users with the push of a button. CD aims to automate the software delivery lifecycle until right before production; continuous deployment automatically deploys every code that passes the tests to production.
It goes without saying, but the basics are important when you are first setting up a transition to CD.
You’re almost there! Now it’s on to the deployment. Key steps include: breaking down the CI workflow into steps, automating the software builds, using a CI framework or building an automation tool to develop the packaging deployment scripts, and consistent reporting and tracking so as to facilitate troubleshooting.
There are some circumstances where Agile may be more appropriate than CD. Those circumstances include:
