Introduction to Eucalyptus Lester Wade Cloud Solution Engineer


Open source software for

building AWS-compatible private

and hybrid clouds


AWS Compatibility

• AWS is the most widely-used public cloud in the world

• The de facto industry standard API

• Large collection of tools and virtual machine images

• Eucalyptus is compatible with several popular AWS APIs

• Elastic Compute Cloud (EC2)

• Simple Storage Service (S3)

• Elastic Block Store (EBS)

• Identity and Access Management (IAM)

• Eucalyptus provides functionality similar to AWS

• Elastic IP addresses

• Availability Zones (Clusters in Eucalyptus)

• AMIs (EMIs in Eucalyptus)

• Security Groups

• .....


AWS - Eucalyptus Partnership


New API Features

• New AWS API-compatible service implementations

• CloudWatch

• AutoScaling

• Elastic Load Balancing

• Further API compatibility enhancements

• Tagging

• Filtering

• ... and more


Orchestration in the Cloud

Looking for a tool with the following properties:

• Easy to get started

• Leveraged the AWS API's

• Doesn't required agents or pre-baked images

• Easily to work on

What is Ansible?

Ansible is an open-source IT orchestration engine that manages on premise and in the

cloud remote devices in a coordinated fashion: servers, networking hardware, and

storage devices


• Simple: Automation in plain English

• Secure: Uses industry-standard SSH

• Efficient: No agent software required on managed hosts

• Powerful: Manage bare metal, virtualized and cloud hosts

• Extensible: Use of any language of preference

• Complete: Configuration management + deployment

Ansible Advantages


Ansible Architecture

(there will be a quiz at the end)


• Over 1,350 GitHub followers and 400 forks

• Quadrupled the number of Pull Requests in less

than 2 months

• Rapid and productive release cycle: 21 modules

added since 1.0, total of 80 modules: “batteries

included”

• De facto standard in Fedora and soon in OpenShift

• Exponential adoption in enterprise, startup, and open

source project environments

Ansible In The Open


A Simple Playbook---- name: install and start apache hosts: all user: root

tasks:

- name: install httpd yum: pkg=httpd state=latest

- name: start httpd service: name=httpd state=running


Orchestration Example

The user executes an Ansible playbook which contains step-by-step instructions on how to perform the update.

Playbooks are simple, human-readable descriptions of IT workflows.



This step updates the app server tier. The servers are going to be updated ten at a time, in a rolling update.

Ansible will talk to the load balancers to coordinate each batch. A maintenance window is also set on the monitoring system.



Now the same thing happens for the web server tier.



Finally, Ansible returns a summary of tasks performed.

Ansible can be configured to store data in a wide variety of data sources, send email reports, and more. If any errors occurred during any of the steps, the administrator will be notified.

Ansible AWS Modules Lester Wade Cloud Solution Engineer


AWS Module Overview

• Modules can be used to easily perform actions/tasks on remote hosts

• Ansible's module library (as of 1.1) contains a number of AWS-related modules:

• ec2 (idempotent requests)

• Used to provision instances

• ec2_facts

• Used to gather metadata fact from instances

• ec2_vol (not idempotent)

• Used to create and attach volume(s)

• s3 (idempotent)

• Used to put objects into S3

• cloudformation (idempotent)

• Used to deploy an AWS cloudformation stack


EC2 Module

• Best used in a provision playbook or as part of a "stack" deployment

• Launch an instance in Ansible's task-execution mode:

ansible localhost -c local -m ec2 -a "image=XXXXXX group=default

key_name=mykey type=m1.small"


Thank you.
