Rapid Application Development!§  Need for speed and need for simplicity

§  New methodologies and technologies make the core coding fast and simple

Rapid Deployment ?!§  Coding is often rapid, but deployment is (mostly) not§  Issue: Different target platforms with different configurations

§  Expanded role of developers: Not only responsible to write code but responsible for full life cycle up to the testing in production environments§  Old developer excuse “it works on my machine” doesn’t count any

longer

DevOps!§  DevOps supports developers to automate testing and

deployments through delivery pipelines

§  But deployments can still be challenging§  Different types of applications§  Different target environments�

§  Containers to the Rescue

Containers vs. VMs!§  Lighter weight than VMs (virtual machines)

Enter Docker!§  Standardizes the packaging of applications and container

runtimes§  Write once run everywhere

Sample Servlet!

Dockerfile!

Build Image!

Run Container!

Sample Application!

Registries to share Images!§  Docker Hub

§  Public§  Private�

§  Docker Trusted Registry

Docker on IBM Bluemix!§  Bluemix is IBM’s application platform in the cloud based on

Cloud Foundry§  IBM extends and connects Docker containers to

production-ready enterprise environments§  IBM hosted private registry§  Run containers in local datacenters or in the cloud§  External IP addresses§  Integrated monitoring and logging§  Security readiness guidance via Vulnerability Advisor

Automation via Delivery Pipelines!§  To simplify the process to build images and run containers,

delivery pipelines can be used §  Different deployment strategies can be used to deploy to

different target environments without downtimes

Take-Aways!§  Docker containers allow the standardized packaging of

applications and easy deployments to different environments

§  Docker is currently the de-facto container standard and is evolving into the Open Container Initiative

§  IBM added enterprise capabilities for Docker images and containers

§  Try Docker in the cloud via the 30 days trial of Bluemix
