When comparing public cloud services such as AWS, Google Cloud Platform, Microsoft Azure, or Linode, you’re likely to notice their specs on IOPS and throughput. These can be impressive numbers, but they’re just a small part of the overall performance factors that need to be considered when choosing the right cloud for your workloads. And they’re not nearly as important as latency.
Sadly, you won’t find numbers on latency on the vendor’s battle cards—so we measured it ourselves to see the performance differences among some popular services.
But first, let’s discuss latency. It’s a cloud’s most important metric because it’s the most user-visible: latency directly impacts the time it takes to load a web page or save changes to a selfie.
