It would be great to see Forrester more forthright on such methodology, however, and this may be a good reminder that Forrester here is not a transparent, peer reviewed journal and doesn't have to show their homework.
AzureStack presumably runs AKS, the same as the Kubernetes service that runs in Azure, which is totally different.
The market size can't be attributed in any way to Azure Stack which is why I was surprised you mentioned it was heavily used. Gartner talks to a wide range of companies usually.
> "We did not evaluate native public cloud container or Kubernetes services."
In which case AKS doesn't show up because the report intentionally excluded it.
Again, I don't understand anything about the methodology of this report, it's very clear it's designed to present some bias, but there isn't enough transparency on what/why/where, and every time I skim it I come up with other questions as to the validity of this report towards any market size determinations whatsoever.
I have another comparison sheet for those if anyone is interested.
The report is from Forrester. I hardly ever read them but Docker has it posted all over its website so I was curious.
Forrester and Gartner seem too high profile to be biased. This one isn't sponsored so the researchers will have had free reign over what was added. If Azure Stack is really in use by many companies I'd be surprised if they missed it.
