Additional Notes
Why is Docker considered lightweight compared to VMs?
Track: Java
Topic: Microservice Architecture
Focus: Docker Containerization
Java: Docker Containerization
Answer
Docker shares the host OS kernel. Frame the concept in practical terms so you can explain it during interview discussion.
Unlike virtual machines, Docker containers share the host system's OS kernel, making them more lightweight and efficient. This allows for faster startup times and reduced resource usage. For example, a Java microservice can run in a Docker container using only the resources necessary for the application, rather than the overhead of a full OS as in a VM.
