CLOUD INFRASTRUCTURE ISN’T CREATED EQUAL - MANY FACTORS AFFECT NETWORK PERFORMANCE TO, FROM DIFFERENT PROVIDERS
Nothing strips the cloud’s ethereal aura like networking, laying bare its physical limitations and vagaries. When it comes to moving data to and from cloud infrastructure, all the technology Google, Amazon and Microsoft can muster can’t overcome the physics of photons traversing a set distance.Given today’s vast global Internet with hundreds of carriers, ingress POPs, cloud regions, continental and undersea cables and vendor peering/cross-connection arrangements, characterizing cloud network performance is a complex, multivariate problem that defies quick solutions and simple summarization. The best we can do is test as many of the most common scenarios as possible and try and wrestle through the messy details. Fortunately, the network measurement experts at ThousandEyes have done the leg work of setting up an intricate fleet of measurement sites and test scenarios, sharing their work in what has become an annual cloud performance benchmark report.
