The document discusses Docker's platform and ecosystem. It describes Docker's mission to build tools for mass innovation by providing a software layer to program the internet. It outlines key components of Docker including Docker Engine, Swarm for clustering multiple Docker hosts, Compose for defining and running multi-container applications, and Docker Hub for sharing images. It also discusses the Linux container ecosystem underpinning Docker and roadmaps for continued development.

- 70. Q&A
Editor's Notes
- Their customer loves the apps they are building so fast for him: George sees $$ glint in his eyes!
- George relishes complexity. Nobody understands how the system works... apart from him.
- QWERTY 3.0 is a disaster, 2 years late
- Docker Hub is Docker’s cloud service for … Publishing and discovering container images through the public registry Team collaboration and automation of application workflows
- DAY 1 REFERENCE “… as we saw yesterday, Docker Content Trust … … uses trust service on Docker Hub (built on Notary) … but now you can stand-up a trust service on-premise alongside DTR …DTR to store, view, and distribute signed images DTR is the only registry on the market with this capability.
- … and to make all this easy to configure and manage, Docker Trusted Registry also features a web-based admin GUI … for insights into the state of the DTR host …
- You have just seen the power of Docker Hub and the Power of Tutum And how they work together And really it is not about dev vs ops it is about dev and ops working together and moving the app through the e2e phases rapidly and predictably seamlessly It was a great demo but what about real life?
- We gave a sneak peek as Project Orca at DCSF in June … Everything you need to deploy and manage Dockerized apps … Complements DTR Integrated stack of our reliable, secure, scalable open source plumbing
- it’s got the features teams need to move quickly with control in shipping apps to any infrastructure
- --- To re-cap, you saw and end-to-end demo of the Docker CaaS Platform Devs using Docker Toolbox and Docker Trusted Registry Ops using DTR and DUCP Work together to move quickly yet with control Who wants to try these out?
- Try these solutions today Break-out sessions and hands-on labs
- And distributed applications are not just something for aggressive web companies. This is an application architecture that is being adopted by all of the leaders of industry…every major enterprise organization is either already there or going down that path because of the agility it provides them in delivering applications that engage with their customers.
