Configuring servers with RightScripts « RightScale Blog
Load balancing is one of the technologies that virtually all our customers are using within EC2, and there is an increasing set of options available for doing it. We’ve been giving advice to our customers for years on what we’ve seen work but we finally decided to spend some time and do a real A-B benchmark comparison of a number of solutions. The test we ran compared the following solutions: HApr
Pushing the Limits of Amazon S3 Upload Performance
Recently I’ve been working on a project where I’ve got millions of relatively small objects, sized between 5kb and 500kb, and they all have to be uploaded to S3. Naturally, doing a synchronous upload of each object, one by one, just doesn’t cut it. We need to upload the objects in parallel to achieve acceptable performance. But what are the optimal parameters when it comes to the number of simulta

Cassandra Performance Testing on EC2 « Geekout
The tests were performed over several days in Sept 2010 with Cassandra 0.6.2 utilizing the supplied contrib/py_stress tests. ** Inconclusive results because of slow EBS drive General EC2 Since the tests are typically large and do not fit in RAM our intent was to test EC2′s hardware performance, not necessarily Cassandra’s performance with things like cached data. As with any performance testing
Multi-machine EC2 Cassandra Setup in 30 minutes « Geekout
Introduction In this post we will walk through setting up a production ready 3 node Cassandra cluster with Munin monitoring running on Amazon EC2 in under 30 minutes. We will also walk through getting the sample Cassandra stress scripts running with a basic load on the 3 node cluster. This post builds on a previous post about how to setup and maintain an EC2 virtual instance with our supplied unat

On Amazon EC2's Underlying Architecture
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? I was curious and needed
AmazonEC2 - HADOOP2 - Apache Software Foundation
Running Hadoop on Amazon EC2 Amazon EC2 (Elastic Compute Cloud) is a computing service. One allocates a set of hosts, and runs one's application on them, then, when done, de-allocates the hosts. Billing is hourly per host. Thus EC2 permits one to deploy Hadoop on a cluster without having to own and operate that cluster, but rather renting it on an hourly basis. If you run Hadoop on EC2 you might c
