What is the primary function of Docker?

To provide hardware acceleration
To build, ship, and run portable cloud applications
To manage databases effectively
To create static web pages

The correct answer is: To build, ship, and run portable cloud applications

The primary function of Docker is to build, ship, and run portable cloud applications. Docker allows developers to package applications and their dependencies into containers. These containers can be easily moved and deployed across different environments, ensuring that an application behaves consistently regardless of where it is run. This portability is essential for modern cloud infrastructure, where applications may need to be deployed in various settings—local development, testing, or production environments. By using Docker, organizations can streamline their development workflows, making it easier to integrate and deliver software efficiently. This capabilities not only enhance developer productivity but also help maintain a reliable and scalable architecture. Other options, like providing hardware acceleration or managing databases, do not align with Docker's focus, and creating static web pages falls outside the scope of Docker's purpose in application lifecycle management.
