Architecture


Simple Architecture


Application

•  Brooklyn Blueprints •  YAML •  Java Classes

•  Entity Tree •  SSH Commands •  No Changes Needed

•  Dockerfiles •  Docker Configuration

•  Automation


Configuration

id: tomcat-‐application name: "Tomcat Web Application" locations: -‐ my-‐docker-‐cloud services: -‐ serviceType: brooklyn.entity.webapp.tomcat.TomcatServer brooklyn.config: docker.dockerfile.url: "https://s3-‐eu-‐west-‐1.amazonaws.com/brooklyn-‐clocker/UsesJavaDockerfile" wars.root: "https://s3-‐eu-‐west-‐1.amazonaws.com/brooklyn-‐clocker/hello-‐world.war" version: "7.0.53" jmx.enabled: true jmx.agent.mode: "JMXMP" jmx.direct.port: "30000+"


Demonstration


Complex Applications

•  Service Composition

•  Multiple Entities

•  Linking via Attributes

•  Clusters and Groups

•  Enrichers and Policies

•  Example •  Cassandra Multi-Region Deployment •  Global Three-Tier Webapp •  Apache Usergrid •  OpenGamma


Placement

•  Adding New Containers

•  Choose Hosts Intelligently

•  Placement Strategy

•  Availability Zone •  Docker Host

•  Choices •  Breadth First •  Depth First •  Minimum CPU Usage

•  Affinity •  DSL or API


Policy

•  Data Based •  Autoscaling •  High Availability

•  Entity Sensors •  Cluster Aggregates

•  Windowed Rolling Average •  Too Hot or Cold •  Fixed Limits

•  Time Based •  Follow The Sun


Demonstration


Roadmap

•  Version 0.5.0 •  Affinity Rules •  Docker Hub Integration •  CPU and Memory Shares •  Volumes

•  Version 0.6.0 •  Software Defined Networking •  Smart Import of Existing Hosts

•  Future… •  Libswarm? •  Kubernetes? •  You tell us!
