Developers and operators are using Docker to reduce friction in software development and operations. For developers, Docker provides disposable environments that improve productivity and testing. For operators, Docker simplifies environment setup and streamlines software updates. The presentation discusses how Docker benefits both developers and operators by improving development workflows and reducing complexity in operations.

Abstract
The software landscape is changing. Products need to get to market faster than ever so the way
we introduce software to end-users is changing… and Docker is shifting the landscape.
Join this session to learn how Docker’s unique capabilities and characteristics solve this
challenge and how CA is helping you to embrace the opportunity. Testing, immutability, CD/CI
and polyglot are all paradigm shifts greatly facilitated by Docker.
Developers, operators, team leads, architects and DevOps managers/execs will all benefit from
this timely and practical session.

Why are we here?
§ Shifting landscape
– Docker is 3.5 years old
– Many Tool and Technology
choices
§ Internet speed
– Agile practices
– CI/CD
§ Software complexity
– Increased maintenance costs

Background
§ What are containers?
– Small, lightweight, encapsulated software functionality
– Share operating system kernel
– Long history (Solaris Zones, LXC)
§ What is Docker?
– Software containerization platform
– Linux container management, simplified
– Standards based
– Docker Inc. and Docker Open Source
Containers and Docker

Developers
Disposable Environment
§ Setup/teardown performance
§ Lightweight – running many
services on a laptop
§ Contained and isolated
dependencies
§ Immutable
§ Development/production parity
– Reducing “works on my
machine/environment”

11. 11 © 2016 CA. ALL RIGHTS RESERVED.@CAWORLD #CAWORLD
Developers
Service Implementation Freedom
§ Free to use the best
tool/framework for the
service
– Polyglot
– Encapsulated dependencies
§ Shifting Ops closer to Dev
– Reduced friction between Dev
and Ops
§ Strong interface contracts

12. 12 © 2016 CA. ALL RIGHTS RESERVED.@CAWORLD #CAWORLD
Developers
Testing
§ Reduced resource requirements
– Actual services vs mock
§ Reducing test execution time
§ High cohesion and low coupling
§ Microservice testing in isolation
§ Reduced fragility due to immutability
– Dependency encapsulation
§ Simplified compatibility testing
– Multiple versions

Operators
Environment Setup
§ Vanilla PaaS
– Docker engine
§ Containers bring their
dependencies
§ Enhanced portability
§ Simplified runbooks
§ Reduced resource requirements
§ Configuration as code
