Quick takeaways
Continuous deployment automates the deployment of release-ready artifacts without manual approval, encouraging best practices such as canary and blue-green deployments.
Microservices-based products offer more flexibility in making smaller changes and allow for more automation in continuous deployment, enabling different teams to work independently and iterate faster.
Deep dives
The Importance of Continuous Integration and Deployment
Continuous integration and deployment are crucial practices in software development. Continuous integration involves producing a release-ready artifact through automated tests and processes. Continuous deployment takes it a step further by automating the deployment of this artifact to runtime environments without manual approval. The key difference between continuous delivery and continuous deployment lies in the need for manual approval. Continuous deployment encourages best practices such as canary and blue-green deployments, and it is achievable even without fully automating all processes.
Considerations for Monolithic vs. Microservices-based Products
Continuous delivery and deployment can be implemented in both monolithic and microservices-based products. While the practices are similar, microservices offer more flexibility in making smaller changes to specific areas. Monolithic products often have a manual approval check in place before releasing a fully-ready artifact, ensuring an extra layer of safety. On the other hand, microservices allow for more automation in continuous deployment, as different teams can work independently, iterating and moving faster.
Prerequisites and Approaches to Continuous Deployment
Continuous integration is a prerequisite for implementing continuous delivery or deployment. It involves automating the build process and having a release-ready artifact. Organizations should not be discouraged from implementing continuous deployment due to incomplete automation or certain tests not being automated. With continuous deployment, manual approval can be contingent on specific checks or tests passing. Orchestrating these checks and balances ensures continuous delivery and a safe deployment process. Companies can gradually move towards a fully automated process while still practicing continuous deployment.
Testing and Customer Experience in Continuous Deployment
Testing is a crucial aspect of continuous deployment. Unit tests are performed in the development environment, integration tests in the staging environment, and specific security scans are conducted before production deployment. Continuous deployment allows for gradual changes in customer experience, utilizing feature flags to control the release of specific features or UI changes. By leveraging statistical analysis and machine learning techniques, developers can automate the process of monitoring metrics and analyze user experience, ensuring a reliable and seamless deployment to customers.
Adam Frank, SVP of Product and Marketing at Armory.io, speaks with SE Radio’s Kanchan Shringi about continuous integration, continuous delivery, and continuous deployment – and how they differ. Frank suggests that organizations begin by identifying how the CI/CD process aligns best with their unique goals, noting that such goals might be different for B2C versus B2B SAAS (software as a service). They also discuss how the process can differ for monoliths compared to microservices-based products. Finally, they talk about continuous deployment as a service and some unique aspects of Armory’s approach.
