● Application dependency hell
● Be language agnostic
● A logical space to run a process
● Flexibility to be more granular with your
compute resources than VM
● A framework to build and run applications

9. Containers are a unit of application

● Dockerfile defines the application

● The image can be shipped easily
and run anywhere
● Both the Dockerfile and image
are versioned
● The container is abstracted from
the OS
● From the image containers are
run
A shippable unit that encases all application the application's dependencies
