Cedexis Measures Latencies of Major U.S. Public Clouds

Cedexis, which specializes in Internet performance monitoring and optimization, released data measuring the performance of major clouds in the U.S. during March/April 2016.

The data includes Real End User Measurements for:

  • AWS
  • Azure
  • SoftLayer
  • Rackspace
  • Google

The report specifically includes findings on the following:

  • Worst to First: Latency of 17 US based Clouds (in Milliseconds)
  • Regional comparison of US based Clouds - US Latency in Milliseconds
  • Regional comparison - 8 best clouds with regard to US Latency, March/April 2016
  • Regional Comparison of top 4 Clouds with regard to Latency
  • US Availability of Clouds – Regional Breakout
  • Southwest latency over a 48 hour period – abnormal diurnal congestion
  • Southwest Availability over same 48 hour period – Google wins!

Cedexis noted that there are significant diurnal patterns that indicate congestion of major peering points, and that this congestion effects the different clouds to varying degrees.
