- 4. For Docker Online Training : +91-999 123 502 • A container is a software that contains an application code and all its dependencies. • Enables an application to run quickly in an isolated environment. • Provide smooth migration from one computing environment to another. • Share the same OS kernel • Works with all major Linux & Windows Server What is Container?

- 8. For Docker Online Training : +91-999 123 502 • Hardware-level virtualization • Fully isolated • Isolated OS • Having its own kernel • Slower in start-up • Many startup process • Upfront resource allocation Virtual Machine vs. Containers • OS-level virtualization • Process-level isolation • Isolated processes/filesystems • Host machine kernel is used • Faster in start-up • Single Start-up process • No upfront resource allocation
