It's nice that all these hosting companies are dropping their prices so much. However, I've found it extremely hard to compare them against each other. I wish someone would put together a site that compared each cloud provider when it comes to specific workloads -- for instance: Postgres and Mysql performance, Redis and Memcached performance, apache-bench, and so on. Even the performance of each virtual CPU is unclear. Does anything like this exist?
