Solution Accelerators> MySQL and Memcached

> Best-practice deployments> Leverage Windows Azure primitives:

> Windows Azure Drive> Windows Azure storage> Discovering IP addresses, other servers,

lifecycle> Dynamic Scaling, Failover, and Upgrades> Automation of application lifecycle

> Instance Manager for remote command

Spotlight: MediaWiki > Powers Wikipedia> PHP-based, usually with MySQL and

Memcached> Used by many companies

> Internal knowledge management> Content management system (CMS)

> Windows Azure benefits> Support traffic spikes> Support unpredictable growth> Minimize possibility of data loss> Minimize downtime

Spotlight: MediaWiki> Technology Requirements

> Web server w/PHP support, MySQL for storage, memcached for caching query results

> What we’ve added : phpMyAdmin and Instance Manager
