SearchBench has received a couple of useful updates since yesterday's initial cloud tests. It can generate search queries based on actual content, and it can export search benchmark results. In gaining these features, it is now possible to use SearchBench to perform some actual performance comparisons. Once again I set up these tests on an extra large EC2 instance. I still have not performed any tuning, and I continue to test Drupal 5 core search...

I ran some initial Drupal search benchmarks with SearchBench on Amazon's EC2 cloud service. These first tests were primarily focused on confirming that SearchBench and EC2 are a good match. They utilized a single server instance, and did not include any server tuning. I used the devel module to create 5,000 random nodes and 10,000 random comments. I indexed this content both with Drupal's core search module, and with the contributed Xapian module. I then...

Continuing my plans to set up an IPVS high-availability LAMP stack on EC2, I needed to add the kernel modules for IPVS. I have been using the CentOS machine images provided by RightScale, which have unneeded services disabled and, although they are set up to work with RightScale's software, work very well for general use. Unfortunately, the IPVS kernel modules are not among those pre-installed on the AMI. I might have expected a simple kernel...

This last week I've had the fortune to have some spare time to play around with Amazon's Elastic Compute Cloud (EC2). I'm pretty interested in the potential for scaling the LAMP stack by having a programmable cluster at the service of your box. A lot of the documentation I find seems to be by people either scaling via dynamic DNS additions when they add more nodes, or by using EC2 nodes as application servers used...

With all the excitement surrounding cloud computing, and specifically Amazon's EC2 (Elastic Compute Cloud) Beta service, I decided it was time to give it a try myself. Without much personal background in the new service, I found that there are an overwhelming number of pages talking about EC2, and even Drupal on EC2 , but didn't locate a simple guide to quickly get me up and running. Having now spent a few hours today learning...
