RightScale for Amazon EC2 Elastic IP Address & Availability Zones

The cloud is accelerating past terrestrial hosting! Today, Amazon unveiled some major upgrades to its service: Elastic IP addresses, Availability Zones, and selectable kernels. The first two are particularly important because they not only eliminate one of the remaining deficiencies of the service, but provide better functionality than what is currently available in common hosting services...Read more

Setting Up a Fault-Tolerant Site with Amazon's Availability Zones

Amazon's Availability Zones are a fabulous new feature that allows users to assign instances to locations that are fault-tolerant from one another yet that have high bandwidth between each other. I wish I could have done something like that as easily when I was responsible for operations at Citrix Online and we had five datacenters worldwide. As I'll explain in this post, what Amazon actually...Read more

DNS, Elastic IPs (EIP) and How Things Fit When Upgrading a Server

Amazon's new Elastic IP (EIP) addresses allow users to allocate an IP address and assign it to an instance of their choice. What's really cool is that each IP address can be reassigned to a different instance when needed. For example, if the first one failed or if a new one is supposed to take its place. Before going into an example, let's review how the Elastic IPs work: You can allocate up to 5...Read more

So it was nice to see the following response to a minor incident the other day posted on the forum : Following up with more information about this morning's event. At 1:31am PST, a...Read more

Top Reasons Amazon EC2 Instances Disappear

The fact that Amazon says up-front that computers fail seems to be the number one concern and criticism of EC2, especially from people who have not used it extensively. I don't actually spend much time thinking about that because in our experience it's not something to worry about. It's essential to take into account when designing a system; whenever we set something up on a machine we...Read more

Deploying Many Rails Sites onto Amazon EC2

One of our customers is deploying many Rails sites onto EC2 - more precisely, many instances of virtually the same site. Basically it has a Rails application and tweaks it for each individual site it sets up. EC2 is a wonderful deployment platform for this type of business because there is little friction in adding customers, since it takes just one button press to get more servers. The overall...Read more

Setting Up Sites on EC2 with RightScale

The key to a successful site setup on Amazon EC2 are scalability and redundancy. RightScale makes this easy by providing ServerTemplates and multi-server deployments.

The 10-Minute EC2 Server

The new Rails All-In-One ServerTemplate we just made public makes it really easy to get your own Rails application running on Amazon EC2 . And it's all free to boot! The ServerTemplate is a collection of RightScripts that install Apache, mod_balancer, Mongrel, and MySQL, and a backup cron script all on one EC2 instance. All you need to do is to specify where your code is located and launch the...Read more

Amazon EC2 Changes the Way MySQL is Used

Amazon EC2 will change the way MySQL is used: it suddenly opens a whole slew of new possibilities. What's really exciting is that it can also simplify the management of MySQL , which enables powerful automation. It takes less than 10 minutes to fire up a fresh MySQL instance, and there's a virtually limitless supply. There is virtually no cost to keeping old database instances around while...Read more
