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
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.
