An Introduction to OpenStack

goals

1. what is it?

2. where did it come from?

3. Who is using it?

4. How can i use it?

what?

in a nutshell

• Open-source software project

• Modules that provide cloud infrastructure

• Independent, driven by community

• Governed by an elected technical board

But really…

just python

code

omg python

don’t panic!

language agnostic

• REST APIs

• SDKs (Language Bindings)

• CLIs

• GUI Console (OpenStack Horizon)

such cloud… many services… wow

• Servers (Nova)

• File storage (Swift)

• Databases (Trove)

• Block storage (Cinder)

• OS Images (Glance)

• Networks (Neutron)

• Identity (Keystone)

• Orchestration (Heat)

• Work queues (Marconi)

• Hadoop (Sahara)

where?

project nebula

• Federal cloud platform

• “take the lead in open, transparent and participatory space exploration and government”

• Efficiency, flexibility, reduced energy costs, reduced setup time, performance.

“This could have fallen apart in a

million different ways.”

Rick Clark

the glorious loopholeProblem

• Existing codebase (eucalyptus) had issues

• Creating a new codebase at NASA was not allowed

Solution

• Create a new OSS project at the weekends

• Contribute back to it during working week

“Launched Nova. !

Apache-Licensed cloud computing, in Python. !

It’s live, it’s buggy, it’s beta. Check it out.”

Josh McKenty, Summer 2010

“It was like finding a long-lost twin…”

It was the weirdest experience I’ve ever had. !

We were using the same tools. !

We had made the same language decisions. !

we both said: ‘Wow, you just wrote the code that we were going to write.’

Who?

LHC• 17 mile long particle accelerator

• 9,000 magnets; cooled with 10 thousand tonnes of liquid nitrogen

• Magnets accelerate particles to 671,000,000 mph. That’s over 11,000 laps per second.

• 600 million collisions per second

• Each collision generates temperates 100,000 times hotter than the core of the sun

Just 2 Requirements

1. Infrastructure that can analyze the most data-intense experiments in human history.

2. IT network for 11,000 Physicists (email, web services, databases, desktop support).

Big data?

• Filter 1PB of data per second with ~1,000+ VMs.

• 35PB of residual data per annum from LHC, which needs mathematical analysis.

• Scale for future growth. By 2015, the LHC will double its energy usage.

The Grid

• 1,000 Nova servers, each with ~12 cores.

• 60k cores in total, tiered architecture.

• During CMS experiments, ~250 VMs are launched in a 5min burst.

How?

installation

$  composer  require  \  

   rackspace/php-­‐opencloud:dev-­‐master

1. Setup client<?php  !require  'vendor/autoload.php';  !use  OpenCloud\OpenStack;  !$client  =  new  OpenStack('my-­‐os-­‐api.com:35357/v2.0',  [          'username'      =>  'foo',          'password'      =>  'bar',          'tenantName'  =>  'baz'  ]);  !$service  =  $client-­‐>computeService('nova',  'region1');

2. choose OS

//  Traverse  \Iterator  collection  $allImages  =  $compute-­‐>imageList();  !foreach  ($allImages  as  $image)  {     if  (preg_match('#^ubuntu#i',  $image-­‐>name))  {       $ubuntu  =  $image;       break;     }  }  !//  Or  instantiate  with  ID:  $ubuntu  =  $compute-­‐>image('{uuid}');

3. choose hardware

//  Traverse  \Iterator  collection  $allFlavors  =  $compute-­‐>flavorList();  !foreach  ($allFlavors  as  $flavor)  {     if  (preg_match('#large#i',  $flavor-­‐>name))  {       $largeFlavor  =  $flavor;       break;     }  }  !//  Or  instantiate  directly:  $largeFlavor  =  $compute-­‐>image('m1.large');

4. launchuse  Guzzle\Http\Exception\BadResponseException;  !/**  @var  $server  OpenCloud\Compute\Resource\Server  */  $server  =  $compute-­‐>server();  !try  {     $response  =  $server-­‐>create([       'name'      =>  'Viva  Italia!',       'image'    =>  $ubuntu,       'flavor'  =>  $largeFlavor     ]);  }  catch  (BadResponseException  $e)  {     printf("An  error  occurred!\n");     printf("Request:  %s\n",  (string)  $e-­‐>getRequest());     printf("Response:  %s",  (string)  $e-­‐>getResponse());  }
