Drupal In The Cloud

&
A Match Made in the CloudHow to best take advantage of the cloud for Drupal Sites

Why cloud?
“The Cloud” is hosting with an API
Programmers Like APIs!
Reliable, Reusable Start States
On Demand
Usage-based Pricing

Where to begin? With Pantheon!
Stand on the Shoulders of Giants
Varnish
Apache HTTPD
APC Cache
Apache Solr
MySQL
Best in class, stable technology

Pantheon

Anonymous Love of Varnish
How much of your traffic is unauthenticated?
Why would you want to build the page each time?
Big spikes are typically unauthenticated..
When @aplusk tweets your site you’ll see this first
Having Varnish will give you time to react if tons of new people start registering..

APC is the Way for Me
APC = speed for site rendering..
..memcached = scale for your database.

Solr Power Keeps Us Warm
Faster and better..
..you can have your cake and eat it too!
You’ll see a huge difference if search is..
..a big part of your site load.
..a source of latency.
..a cause user frustration.

What is openstack
A community effort to build the best fully open data center operating system

OpenStack has a Mission
"To produce the ubiquitous Open Source cloud computing platform that will meet the needs of public and private cloud providers regardless of size, by being simple to implement and massively scalable."
[Announced July 19th, 2010 and ratified by 25+ companies and 100+ community members]

Open 4 Times, Not Just Once
Open Source: We are committed to creating truly open source software that is usable and scalable. Truly open source software is not feature or performance limited and is not crippledlicensed under Apache 2.0.
Open Design: Every 6 months the development community will hold a design summit to gather requirements and write specifications for the upcoming release.
Open Development: We will maintain a publicly available source code repository through the entire development process. This will be hosted on Launchpad, the same community used by 100s of projects including the Ubuntu Linux distribution.
Open Community: Our core goal is to produce a healthy, vibrant development and user community. Most decisions will be made using a lazy consensus model. All processes will be documented, open and transparent.

Current Infrastructure Projects
OpenStack Compute
REST-based API
Hardware agnostic - commodity hardware, RAID not required
Hypervisor agnostic - support for Xen and KVM in initial release
Horizontally scalable
Asynchronous eventually consistent communication
OpenStack Object Storage
Object store, Distributed, REST-based API, No central database
Hardware agnostic - commodity hardware, RAID not required
Account/Container/Object structure (not file system, no nesting)
Replication (N copies of accounts, containers, objects)
Data distributed evenly throughout system
Scalable to multiple petabytes, billions of objects

Current Interface Projects
OpenStack Web Control Panel
Cappuccino framework
Ruby JSONP API proxy
OpenStack iPhone / iPad Control Panels
Mobile application management control panels
OpenStack Android Control Panel
Mobile server and storage management control panel

How Can Drupalists Help?
Infrastructure software needs an interface
Drupal + APIs = world class control panel
