Scalr is an auto-scaling solution for EC2, a bit like RightScale, but cheaper. They give you some nice infrastructure like a MySQL master/slave replication setup, and distributed cron jobs.

We’ve switched to use Amazon EBS for a few months now. Therefore, we have been able to have a good night’s sleep without worrying our database disappearing. Here’s a quick guide.

Automation is the underlying foundation of the revolution (some say disruption) in Information Technology that is currently happening and has been branded as cloud computing.

Excellent introduction to Puppet for cloud management by Jeff Wallace, featuring EC2 and Rackspace Cloud integration, Puppet classes, using Ruby logic in ERB templates, and inheriting node definitions to create identical configurations.

After you rebundle a running instance to create a new image, you can then run new EC2 instances of that image.

At OpenX we recently completed a large-scale deployment of one of our server farms to Amazon EC2. Here are some lessons learned from that experience.

Heroku is the instant ruby platform. Deploy any ruby app instantly with a simple and familiar git push. Take advantage of advanced features like HTTP caching, memcached, rack middleware, and instant scaling built into every app. Never think about hosting or servers again.

Many people know that Amazon Web Services are one of the big players in the cloud computing business, and especially their Infrastructure as a Service offering EC2 is becoming increasingly popular. Few people know that EC2 is probably one of the biggest Xen installations deployed. But how many know how EC2 actually works and how the underlying architecture is constructed?

We have been doing various experiments in our ec2 web serving cluster to serve maximum traffic at the minimum costs. I thought our experience will be useful to many other people using ec2.
