This meet will cover the installation of Apache, PHP, Python and Mysql on an Elastic image of Ubuntu 10.4 on AWS.
Then we will do the same install with nginx, fastcgi instead of Apache and the rest on the Ubunto 10.4 on AWS. Another variant would include persistent mysql storage using EBS volume.
Another option is to show a detailed installation of Django on either of the above frameworks.
Then we will point a website to it and install a CMS such as Drupal 7 and / or Wordpress 3.0.
We will also cover how to avoid unnecessary EC2/S3/EBS costs by putting the machines in the right availability zones etc.
This is going to be a awesome presentation you wont want to miss!!!
