Continuous Delivery
/kənˈtɪn.ju.əs dɪˈlɪv.ər.i/
noun — “getting your code out the door automatically, like a vending machine for software.”
Continuous Delivery (CD) is a software engineering approach where code changes are automatically prepared for release to production, ensuring that the software is always in a deployable state. Unlike traditional release cycles that batch features and fixes, Continuous Delivery emphasizes small, incremental updates with automated testing and validation, reducing risk and accelerating delivery timelines.
Containerization
/kənˌteɪ.nə.raɪˈzeɪ.ʃən/
noun — “packing your apps so they behave anywhere, like Tupperware for code.”
Containerization is the practice of encapsulating an application, along with its dependencies, configuration, and runtime environment, into a lightweight, portable container. Unlike traditional virtual machines, containers share the host operating system kernel but maintain isolation between processes, libraries, and configuration, ensuring consistency across development, testing, and production.
