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.

DESIGN FOR FAILURE

No one component can bring down the entire application


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 MACHINESEach 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.

DOCKERThe 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.


Challenges of Using MicroServices and Containers

TESTING OF MICROSERVICES


Containers and CA

CA release automation includes an extensive action pack for working with Docker including:

Docker Container Management

Docker Image Management

Docker Registry

DYNAMIC CREATION AND MANAGEMENT OF

CONTAINER ENVIRONMENTS

DYNAMIC PROVISIONING OF TESTING NODES AND

RAPID CREATION OF ENVIRONMENTS FOR

TESTING AND DEVELOPMENT


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)

CA APM can:

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 microserviceinstances

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

Microservices Fabric


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.
