Can

12. A standard container
that is loaded with
virtually any goods,
and stays sealed until it
reaches final delivery.

Solution: Intermodal Shipping Container

13. • 90% of all cargo now shipped in a standard container
• Order of magnitude reduction in cost and time to load and unload ships
• Massive reduction in losses due to theft or damage
• Huge reduction in freight cost as percent of final goods (from >25% to <3%)
àMassive globalization
• 5000 ships deliver 200M containers per year
This Spawned an Intermodal
Shipping Container Ecosystem

14. An engine that enables any
payload to be encapsulated
as a lightweight, portable,
self-sufficient container…
…that can be manipulated
using standard operations
and run consistently on
virtually any hardware
platform

Containers are isolated, but
share OS kernel and, where
appropriate, bins/libraries
…result is significantly faster deployment, much
less overhead, easier migration, faster restart

Step One: Create a Lightweight Container
(vs. VMs)

17. A set of slides from IBM: Comparing Docker (Blue) to VM (Red)

18. • Container technology has been around for a while
• Use limited to specialized organizations, tools & training. Containers were not
portable
• Analogy: Shipping containers are not just steel boxes.
• With Docker, Containers get the following:
-­‐ Ease of use, tooling
-­‐ Re-usable components
-­‐ Portable
-­‐ Able to move between any of the above in a matter
of seconds-no modification or delay
-­‐ Ability to share containerized components
-­‐ Interoperability with all existing devops tools
-­‐ Self contained environment—no dependency hell
-­‐ Tools for how containers work together: linking, nesting,
discovery, orchestration, ++
Type 1 Hypervisor Linux Containers docker
Step 2: Make the Containers Easy to Use,
Standardized, Interoperable, Automatable

29. Conclusion
• Enables applications to be built
flexibly and deployed flexibly
• Provides greater degree of visibility,
control, and management of what
runs where and what components
are allowed
• Massive cost, speed, efficiency
savings
• Docker is becoming the standard
for containerization
• Rackspace is a true leader in
enabling this revolution!
• Multiple forces are driving a
reconsideration of how applications
should be created, built, deployed,
scaled, and managed
• We believe that the right approach
is to decouple application
management from infrastructure
management
• Container based approach
(vs. VM approach) provides right
level of abstraction
• Enables infrastructure to be
managed consistently and stably
