1 like578 views
The document discusses the evolution and advantages of Docker and container technology for application development and deployment, highlighting its capabilities for portability, efficiency, and standardization. It draws analogies to intermodal shipping containers to illustrate how Docker minimizes operational complexity and accelerates deployment processes. The conclusion emphasizes Docker's role as a leader in containerization, enabling organizations to reevaluate application management and infrastructure integration.

Mul$plicity of GoodsMul$pilicity of methods for transpor$ng/storing Do I worry about how goods interact (e.g. coffee beans next to spices) Can I transport quickly and smoothly (e.g. from boat to train to truck) …in between, can be loaded and unloaded, stacked, transported efficiently over long distances, and transferred from one mode of transport to another 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%) àMassive globalization • 5000 ships deliver 200M containers per year This Spawned an Intermodal Shipping Container Ecosystem

- 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
