Abstract
Containers and microservices are billed as a way
to aid companies in their release processes. But,
as the number of them sprawl out, have you
just created another level of complexity to
manage? Hear from experts how you can
harness the power of these innovations and
delight your customers.

Leveraging Containers with MicroServices
CONTAINERS ARE AN IDEAL TECHNOLOGY FOR THE CREATION
AND DEPLOYMENT OF MICROSERVICES
CONTAINERS ARE A LIGHT-WEIGHT RUNTIME ENVIRONMENTS
 Contains many of the core components of a virtual machine
 Isolated services of an operating system
 Designed to make packaging easy and execution of services smooth.
What is a Container

What is Docker
Docker is an open platform for developers and
sysadmins to build, ship, and run distributed
applications and consists of:
 Docker Engine, a portable, lightweight runtime and packaging tool.
 Docker Hub, a cloud service for sharing applications and automating
workflows.
 Docker enables apps to be quickly assembled from components and
eliminates the friction between development, QA, and production
environments.
IT can ship faster and run the same app, unchanged,
on laptops, data center VMs, and any cloud.

Docker and Virtual Machines
VIRTUAL MACHINES
Each virtualized application includes not only the application - which may be
only 10s of MB - and the necessary binaries and libraries, but also an entire
guest operating system - which may weigh 10s of GB.
DOCKER
The Docker Engine container comprises just the application and its
dependencies. It runs as an isolated process in userspace on the host operating
system, sharing the kernel with other containers. Thus, it enjoys the resource
isolation and allocation benefits of VMs but is much more portable and efficient.

Containers and CA
CA release automation includes
an extensive action pack for
working with Docker including:
 Docker Container Management
 Docker Image Management
 Docker Registry

Docker with CA Release Automation
A demonstration of Release
Automation working with Docker
can be found on YouTube
 Containers are provisioned
dynamically
 Containers are removed if the
application testing is successful

Monitoring and Docker
 Monitor applications running in Docker containers
(e.g. Tomcat, node.js) - as if they were running on a
virtual or physical server
 Monitor Docker engines through Docker Remote
API
 Run in Docker containers (not recommended for
production use)

API Gateways for Microservices
POPULAR PATTERN FOR THE MICROSERVICES PERIMETER
 Enforces access control and security
 Aggregates API calls to reduce network traffic
 Handles dynamic routing to ephemeral microservice
instances

Newman (Thoughtworks)

CA API Gateway for Microservices
HANDLES KEY REQUIREMENTS FOR GATING MICROSERVICES
 API-centric access control (OAuth, OpenID Connect, JWT)
 Configurable logic framework for Microservice aggregation and dynamic routing
 Interoperability with messaging protocols such as AMQP
 Compatible with leading Microservice solutions like Consul
 Automation and deployment through fully-featured management API

Micro Services can aid application development teams to embrace a continuous
delivery methodology and Containers are the perfect mechanism to deploy these
microservices.
CA Technologies have a range of products that can help integrate containers into
your development life cycle and incorporate these into your application eco system.
