zones• 2006 Cloud IaaS• 2009 platform virtualization (PaaS)• 2013 Docker

Docker now
A platform to build, ship, and run any app, anywhere
docker engine docker hub docker-machine docker-compose docker-swarm kitematic
docker-compose: running multiple containers Run your stack with one command: docker-compose up Describe your stack with one file: docker-compose.yml
web: build: . command: python app.py ports: - "5000:5000" volumes: - .:/code links: - redis:redis

Docker Inc, the company
Headcount: ~130 Revenue:
− t-shirts and stickers featuring the cool blue whale− SAAS delivered through Docker Hub− Support & Training− soon: Docker Hub Enterprise, behind the firewall
Separation of concerns:Dave the Developer
Inside my container:− my code− my libraries− my package manager− my app− my data
Separation of concerns:Oscar the Ops guy
Outside the container:− logging− remote access− network configuration− monitoring
Swarm in a nutshell Docker REST API (>85%)
Resource management (CPU, Mem, Networking)
Advanced scheduling with constraints and affinities
Multiple Discovery Backends (hub, etcd, consul, zookeeper)
TLS: Encryption & Authentication
Swarm beta integrations Fully integrated with Machine Partially integrated with Compose Mesos integration has started in
collaboration with Mesosphere.
Swarm load balancing: interlock
