ECU’s were not the simplest approach to describing a virtual CPU, but they at least had a definition attached to them. Operations managers and those responsible for calculating server pricing could use that measure for comparison shopping. But ECUs were dropped as a visible and useful definition without announcement two years ago in favor of a descriptor — virtual CPU — that means, mainly, whatever AWS wants it to mean within a given instance family.<\/p>\n

A precise number of ECUs in an instance has become simply a “virtual CPU.”<\/p><\/blockquote>\n\n","protected":false},"excerpt":{"rendered":"\n
