Containerization is a method of virtualization that allows applications to run in isolated environments called containers. These containers encapsulate the application and its dependencies, enabling consistent performance across different platforms and environments. They provide portability, scalability, and flexibility, making them ideal for enterprise application development. By using containerization, developers can package applications with all the necessary libraries, configurations, and dependencies, ensuring easy deployment and smooth operation. Containers also enhance security by isolating applications and limiting their access to resources. Overall, containerization streamlines the development and deployment process, accelerates software delivery, and provides a more efficient and reliable way to develop enterprise applications.
