Hi Joshua, we have been hosting our django sites on EC2 for about 9 months now.
We are quite happy with it but there are some things you have to take care of: - we recently had a downtime, because the host system crashed. We had a new instance up and running pretty fast but you have to keep in mind: there is no self-healing mechanism to e.g. broken HDD on EC2. You need to have a backup plan. An Amazon support employeee send me this reply afterwards: "Instances depend on the health of the underlying host. The component that breaks most often are hard disks, so if the instance had any data stored on the disk, it may not be recoverable if there was a fatal failure, so moving an instance is not easily possible. In general, we recommend that you architect your system in a way so that a single instance failure does not disrupt the overall operation of your system. We also recommend keeping current backups." - For planning your infrastructure this blogentry might be quite helpful: "Experiences deploying a large-scale infrastructure in Amazon EC2 " <http://agiletesting.blogspot.com/2009/04/experiences-deploying-large-scale.html > - we do manage every ressource with SVN. Even the SQL-dumps are periodically persisted via SVN. For our sites (90% corporate websites) this is a possible solution. I wouldn't recommend this for community websites. - On the high traffic sites we serve the media with Cloudfront. Runs very smooth. - Site data, logs and config-files are located on a mounted EBS. - The best deal for the buck is a medium instance, find more information here: <http://www.paessler.com/blog/2009/04/03/prtg-7/testing-cloud-computing-performance-with-prtg-performance-comparison-of-amazon-ec2-instance-types/ > "Our conclusion of these tests is that we will mostly use the “c1.medium” instances (”High CPU Medium Instance”) for webhosting and other performance-relevant uses because it offers 150-300% more performance (for CPU, disk and memory) than “m1.small” instances while only costing 100% more." Hope that information helps! Have a great day! Best Joern ----------------------------------------------------------------------------------------------- beyond content GmbH Dipl.-Ing.
