Magento is an open-source e-commerce platform built on Zend PHP and MySQL. It is widely adopted by online retailers with some 150,000 sites known to use it. Single server setups are easy to set up, but if your store is a huge success, then you probably need to think about clustering your environment with multiple servers. Clustering is done at the web, database and file-system level, as all web nodes need access to catalog images. 

This post is similar to our previous posts on scaling Drupal and WordPress performance, and focuses on how to scale Magento on multiple servers. The software used is Magento version 1.7.0.2 , nginx, HAProxy, MySQL Galera …

Thanks to everyone who was in attendance on 05 June 2013 for my “Choosing a MySQL HA Solution” webinar. If you weren’t able to make it but are interested in listening to the presentation, it’s currently up and available for viewing over at percona.com.

My apologies if we weren’t able to get to your question during the initial session, so I’ll address those lingering questions in this post, along with providing a bit more detail on some of the questions that I did cover during the session.

Q: What is the reason that I recommended DRBD be used only on physical hardware and not on virtual machines?
A: I covered this a bit during the session, but to provide a bit more commentary. There …

When looking at high availability for any CMS, and particularly for Drupal, the list of contenders for part or all of the solution is growing and can be daunting. We'll take a look at the various parts of a solution and what options we have.

Selecting the most appropriate solution for a MySQL HA infrastructure is as much a business and philosophical decision as it is a technical one, but often the choice is made without adequately considering all three perspectives.  When too much attention is paid to one of these aspects at the cost of the others, the resulting system may be over-engineered, poorly-performing, and/or various other flavors of suboptimal.

On Wednesday, June 5, at 10 a.m. PDT (1700 UTC), I will be presenting a webinar entitled, Choosing a MySQL HA Solution, in which we’ll explore the topic of MySQL HA from each of these perspectives.  The goal will be to motivate your thinking about HA in a holistic fashion and help …

Drupal is one of the most popular Content Management Systems (CMS) and is used increasingly in high-visibility sites, such as www.whitehouse.gov. This has brought a lot of attention on how to get the most performance out of Drupal and how to improve the availability of such sites. In this blog series I'll take you through the basics and on through to designing your own HA Drupal site.

But first, we need to understand what the challenges are in getting Drupal (or indeed any CMS) working on multiple servers in such a way as to ensure high availability and performance.
