A characteristic of containerization in application deployment is its ability to encapsulate an application and its dependencies within a single container. This ensures that the application runs consistently across various computing environments, eliminating issues related to environment discrepancies. Containers are lightweight, allowing for rapid deployment and scaling of applications. Additionally, they can be orchestrated easily using tools like Kubernetes, which manage the deployment, scaling, and operation of application containers in clusters. This technology enhances efficiency and resource management in development and production environments.
