+# Container vs VM
+
+---
+
+## Content
+
+We can think of a Docker container as a light-weight virtual machine. But unlike a VM which creates a whole virtual operating system each time it runs, Docker's containerization architecture allows it to share a lot of the host's operating system resources across containers.
+
+A virtual machine is more isolated from the host but much heavier because it requires more resources. Docker is less isolated but the containers require significantly less resources, allowing us to easily run thousands of them on a single host. This approach provides a non-trivial performance boost and reduces the size of the application.
+
+Containers only virtualize the operating system, not the underlying hardware. They contain the code, system tools and libraries, and the runtime needed for multiple applications. This is why containers are often preferable when multiple applications using the same operating system are needed.
+
+If virtual machines abstract away the hardware, containers abstract away the operating system.
+

+
+## Practice
+
+Docker container is more ??? than a VM which allows it to be started, stopped and replicated more ???
+
+* light-weight
+* efficiently
+* isolated
+* safely

+
+## Revision
