• Docker is a tool designed to make it easier to create,
deploy, and run applications by using containers.
• Containers allow a developer to package up an
application with all of the parts it needs, such as
libraries and other dependencies, and deploy it as one
package.

What it is a container?
7
A container is a standard unit of
software that packages up code and
all its dependencies so the
application runs quickly and reliably
from one computing environment to
another.

Modernize with Containers

• Provide a standard way to package your
application’s code, configurations and
dependencies into a single object.
• Share an operating system installed on
the server and run as resource-isolated
processes, ensuring quick, reliable and
consistent deployments regardless of
environments.

Benefits of containers
11
• Applications and dependencies defined as code.
• Easier to manage applications built as microservices.
• Standardized packaging enables automated testing
and deployment.
• Consistent implementation model enables easier
monitoring.
• Built-in versioning and dependency declaration enable
security and compliance controls.
