I am very happy to announce that my first book, Host Your Web Site in the Cloud is now available! Weighing in at over 355 pages, this book is designed to show developers how to build sophisticated AWS applications using PHP and the CloudFusion toolkit. Here is the table of contents: Welcome to Cloud Computing. […]

A wide variety of Oracle applications have been certified for use on Amazon EC2 with virtualization provided by the Oracle VM (OVM). The following products are now fully certified and supported and you’ll be able to run them in the cloud on production workloads before too long: Oracle E-Business Suite Oracle PeopleSoft – Enterprise Applications […]

We’ve just introduced four cool new features for Amazon EC2. Instead of trying to squeeze all of the information in to one ridiculously long post, I’ve written four separate posts. Here’s what we introduced: Resource Tagging -Tag the following types of resources: EC2 instances, Amazon Machine Images (AMIs), EBS volumes, EBS snapshots, and Amazon VPC […]

Many of our customers create large numbers of EC2 resources. Some of them run hundreds or thousands of EC2 instances, create thousands of EBS volumes, and retain tens of thousands of EBS volume snapshots. This growth has meant that the corresponding Describe APIs (DescribeInstances, DescribeVolumes, and DescribeSnapshots, to name a few) can return results that […]

It is really easy to start up that first Amazon EC2 instance, and then another, and another as you find more and more ways to put it to use. It is really easy to create some EBS volumes, attach them to your instances, and to store lots and lots of data on them. The same […]

The Amazon EC2 API includes functions which create resources such as instances, disk volumes and snapshots, IP addresses, and key pairs. Some of these functions create the resources in a synchronous fashion and you can determine the success or failure of the request by examining the value returned by the call. Other functions work in […]

You can now import your own RSA keypair (or the public half, to be precise) for use with your Amazon EC2 instances. Why would you want to do this? Here are a couple of reasons: Trust – By importing your own keypair you can ensure that you have complete control over your keys. Security -You […]

It is great to see our customers putting EC2’s new Cluster Compute instance type to use in High Performance Computing (HPC) scenarios. Here are two example applications: MathWorks / MATLAB The MATLAB team at MathWorks tested performance scaling of the backslash (“\”) matrix division operator to solve for x in the equation A*x = b.
