There can be a good deal of variation in performance across cloud providers, the 2019-2020 edition of ThousandEyes' Cloud Performance Benchmark report found.
The 72-page report is based on a study that looked at Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, Alibaba Cloud and IBM Cloud over a period of 30 days from a number of vantage points. ThousandEyes collected 320 million data points from 98 global metro locations to gauge performance across the public cloud services.
The report found that both AWS and Alibaba Cloud rely on the public Internet for much of the data transport, which means there is the potential for unknown risks to cloud performance to be introduced as neither company owns the data links. AWS does have its own private network, known as the AWS Global Accelerator, though apparently it doesn't always outperform the public Internet.
