Opening Up Cloud Computing with Aeolus

What is cloud computing

In the computing world there are three distinct roles

Developers

I.T.

Management

What is cloud computing

Developers need I.T. to manage resources,

I.T. needs developers to write software to address their needs

What is cloud computing Neither does each others job particularly well

What is cloud computing

Current challenges: The more time developers manage resources, the

less time they are writing code

Infrastructure often goes unused, servers need to be up 24x7 even if there is no demand

Demand can scale very quickly, a web server may be hit hard one day but the next day is not accessed at all

What is cloud computing

Developers are just looking for a way to quickly deploy code

Setting up infrastructure is costly (people, time, energy, etc)

Maintaining infrastructure is even more costly (fault tolerance, load balancing, high availability)

What is cloud computing

Current trends in practice Developers often spend lots of valuable time maintaining

systems

Excessive hardware is ordered in bulk incase of limited periods of high demand It is cheap right... ? Wrong, electricity, rackspace, synchronization mechanisms, etc

costs $

Power and internet failures still happen, systems still become unavailable, dispersing workloads geographically is all but impossible for a small business

What is cloud computing

Enter cloud computing

What is cloud computing

Pre-configured computing clusters which can be used to rapidly setup a computational environment to deploy code extremely rapidly

Outsourcing the data-center if you will

Provides a way to setup virtualized machines very quickly with a few clicks of a mouse button

Resources are shared, so if a customer is not using some processing power for example, it is available for others to use But when they need that computational power it is there instantly

What is cloud computing

Future opportunities Computational power and resources can now be

accessed and bought on demand like any other utility – eg electricity, gas, water

Developers spend less time maintaining systems and more time at what they are good at, writing code

Snapshots of systems can be easily taken and reproduced

Cloud Solutions (and the problems they present)

Currently Amazon EC2 is the 800lb gorilla in the room

Many other different cloud providers exist Rackspace / Google App Engine / RHEV

The problem is that these all have their own interfaces both graphical and APIs (programmatic interfaces developers can

interface their software with)

Alot are proprietary, promoting vendor lockin eg if I am accustomed to Amazon's interface and tools, and they

decide to raise their prices, I have no choice but to go with it

The Ultimate Solution

Aeolus - An Free / Open Source Cloud Computing Framework www.aeolusproject.org

Takes care of all the nitty / gritty details of interfacing w/ the different cloud providers

Presents a simple consistent interface to control and monitor various cloud providers

The code is out there, available for anyone to modify no chance of vendor lockin

The details

To start off Aeolus defines terminology used to describe clouds and instances in an abstract manner Cloud Provider - A managed infrastructure providing resources which instances will

run on

Instance - A virtualized operating system which runs on a a cloud provider

Image - a snapshot of an instance which can be used to reproduce and scale instances quickly

Realm - a grouping of instances (usually running in a single geographic location)

Hardware Profile - a description of computational resources that is either made available by a cloud provider required by an instance to run on a cloud provider used to match instances with clouds to run on (that satisfy the instance demands)

The details

Aeolus provides several sub-projects used to satisfy various functional requirements needed to implement this terminology

Deltacloud - the core API, or interface which programmers can use to control and monitor instances running on a cloud

Imagefactory - command line tools used to create cross-cloud images

IWHD - A generic key/value store used to stage data to be able to be pulled into any cloud provider

OZ - A mechanism to bootstrap a cloud instance w/ JEOS + the ability to install additional software after that

Conductor - The web interface orchestrating all of this

The details

Demo

Migrating a running instance from one cloud provider to another

Lets say you have an instance running on EC2 and Amazon changes its terms of service

You want to move this instance to rackspace

Here is how...

(command line walkthrough, graphical mechanisms coming soon)

Demo

Instance Running On EC2

Demo

Instance running on EC2 (running mediawiki)

Demo

View My EC2 Instance (from the command line)

Demo Log into instance

Grab a snapshot

Demo

View Rackspace images we can start instances with

Demo

Start a new instance on Rackspace using the selected image

Demo
