Docker OrchestrationProduct Brief

Ensuring Distributed Application Portability

The promise of distributed applications is to increase

the rate of innovation while decreasing the rate the

issues due to an application architecture that loosely

couples many different small applications together.

Each small application or service can be changed

independently of the others. The Docker

orchestration products empower developers and IT

operations to easily build, ship and run a new

generation of fully portable distributed applications.

Seamless application portability means that a

developer can leverage the same orchestration tooling

when building and shipping the application from dev

to build to test while IT operations can use the same

tooling to run, manage and move the application

across environments and clouds.

Docker Machine

Docker Machine is an orchestration tool that enables

developers and IT operations to go from “zero to

Docker” in minutes. A single command automates

the multiple steps of the Docker setup process by

provisioning the “host infrastructure” (e.g. VM for a

Docker Engine) and installing Docker Engine on that

host. Organizations can quickly and easily deploy

Docker in their environment. Docker Machine

supports drivers to all major infrastructure providers

to automatically provision environments locally, in the

datacenter and in the cloud.

Docker Swarm

Docker Swarm is an orchestration tool that provides

native clustering of Docker Engines, scheduling

capabilities of application containers and integrations

with ecosystem partners. Swarm provides a uniform

developer experience at any scale, as developers build

and ship applications, while providing the operational

freedom to choose infrastructure and tooling

optimized for the application.

The native clustering and scheduling capabilities of

Swarm can scale with the application development

lifecycle from one laptop to spanning hundreds of

hosts in production. Any number of Docker Engines

into a Swarm, organizations are able to pool the

resources across those Engines into a single virtual

Engine to run application containers. The scheduling

capabilities of Swarm determine the right host in a

cluster for speci�c containers, assigns the right

resources, and uses Docker Hub for host discovery.

Swarm provides operational �exibility with a

“batteries included but swappable” approach

supported by partners in the Docker ecosystem.

Partners leverage the Swarm API to create

value-added capabilities while maintaining a uniform

Docker experience for developers. These integrations

ensure distributed application portability across any

infrastructure, while providing operations teams the

�exibility to leverage existing tools or select the

Docker-based partner infrastructure that they believe

is best optimized for their speci�c application.

Machine: At a Glance

• Auto-provision hosts

• Auto-install Docker Engine

• Ready in Minutes

• Infrastructure PartnerIntegrations

Docker Compose

Docker Compose is an orchestration tool that

simpli�es building and shipping multi-container

distributed applications. Developers build a simple

declarative YAML �le that de�nes which containers

comprise the application and the links that they have

to each other. Compose creates and maintains a

logical de�nition of a distributed application that can

move from a developer’s laptop to QA environment

to staging and all the way into production.

Compose: At a Glance

• Simplify Multi-Container apps

• Easy to build and update

containers: web: build: command: python app.py ports: - “5000:5000” volumes: - .:/code links: - redis environments: - PYTHONUNBUFFERED-1redis: image: redis:latest command: redis-server --appendonly yes

Swarm: At a Glance

• Native clustering andscheduling

• Better resource utilization

• Better HA and failover

• Partner Integrations
