In I/O Performance (no longer) Sucks in the Cloud, I said Many workloads have high I/O rate data stores at the core. The success of the entire application is dependent upon a few servers running MySQL, Oracle, SQL Server, MongoDB, Cassandra, or some other central database. Last week a new Amazon Elastic Compute Cloud (EC2) instance type based upon SSDs was announced that delivers 120k reads per second and 10k to 85k writes per second. This instance type with direct attached SSDs is an incredible I/O machine ideal for database workloads, but most database workloads run on virtual storage today.
