Per hour on Windows, in each type's cheapest region. Typical spot: per pricing run of the last 7 days, the cheapest zone's spot price, averaged, as the finder shows it with that region selected. On-demand: the same region's price. Per vCPU-hour: the spot price, or without spot the on-demand price, per vCPU. Every region is under Prices by region.
Description #
The C1 instance family, generally available since May 2008, features Intel Xeon processors. These compute-optimized instances are designed for compute-intensive tasks requiring high CPU performance. C1 instances provide high network performance. Instance storage includes SSD, with varying sizes depending on the specific C1 instance type.
