Which technologies would you prefer for deployment: containerization or virtual machines?

The choice between containerization and virtual machines depends on the specific project requirements and infrastructure.

Containerization (e.g., with Docker) is preferred if you need:

• Rapid deployment and scaling of applications.
• Lightweight isolation without the overhead of running a full OS.
• To use a microservices architecture.

Virtual machines are suitable when:

• Full isolation with its own OS kernel is required.
• Different operating systems need to be run on the same host.
• Security requirements are better addressed at the hypervisor level.

In modern DevOps practices, containers are often chosen for applications, while virtual machines are used for infrastructure and more heavyweight isolated environments.
