Solution: Intermodal Shipping Container
…in between, can be loaded
and unloaded, stacked,
transported efficiently over
long distances, and
transferred from one mode of
transport to another
A standard container that
is loaded with virtually any
goods, and stays sealed
until it reaches final
delivery.

…that can be manipulated
using standard operations and

any hardware platform
An engine that enables
any payload to be
encapsulated as a
lightweight, portable, self-
sufficient container…

Why it works — separation of concerns
Oscar the Ops Guy
Worries about what’s
“outside” the container
• Logging
• Remote access
• Monitoring
• Network config
All containers start, stop,
copy, attach, migrate, etc. the
same way
Dan the Developer
Worries about what’s “inside”
the container
• His code
• His Libraries
• His Package Manager
• His Apps
• His Data
All Linux servers look the
same

Docker Containers
A technical view into the shared and layered file systems technology
Docker uses a copy-on-write (union) filesystem
New files(& edits) are only visible to current/above layers
Layers allow for highly-efficient reuse
More containers per host – higher overall server utilization
Faster start-up/download time – base layers are "cached"

Docker Delivers Innovation, Speed and Savings
Deploys 1,500X
a week
“Docker gives us more speed and
speed for us is a huge measure
of our transformation. Getting
value to the customers faster,
that’s where Docker helps us.”
CI jobs run over
60% faster
“Docker is a natural fit for us. We
wanted testing environments that
we could change easily and
Docker handles this for us”
Ships 100X a day
“I love Docker. It’s simple for
developers and it works for ops.
There is a really positive
emotional connection that Docker
has created with our developer
community “

How can you get started?
o Piece by piece
o Small use cases
o Grow with successes
o Understand the technology
o Then implement on something that brings value to all
your necessary platform components…
