Public cloud IaaS usage: results from Symposium Gold Coast 2015

By Michael Warrilow | October 28, 2015 | 2 Comments


As I type this, it’s a few hours before the final day of Symposium Gold Coast 2015. I’ve been honoured to have a range of interactions on cloud strategy, cloud challenges … and some cloud (as well as virtualisation) successes! It’s been a great event,

During my sessions, I’ve been using interactive polling. I find this a great way to get a little more accuracy (and anonymity) than raising of hands.

As promised, I am sharing the results … noting these are skewed^ … but that’s actually what makes them interesting.

Below are the polling results for my question of use of public cloud IaaS.

Survey result: Is your organisation using public cloud IaaS? 76% using, to various degrees
Question: “Is your organisation using public cloud IaaS?” (n=95, October 2015, Symposium Gold Coast).


This fits with the pattern of later-start, faster-adoption of public cloud IaaS I’ve seen in Australia / New Zealand since ~2014. It also contrasts starkly with the (broader, statistically-valid survey results from ABS). Of particular note, this more aggressive adoption has it’s own set of challenges …

[insert small sales plug] Gartner clients can, of course, ask how to avoid these challenges. [end plug].

I hope you find these results of value.


^ I say the results are skewed because:

  1. All respondents are self-selecting (to attend a session on private and hybrid cloud, and to participate)
  2. Results are primarily – but not exclusively – Australian and New Zealand attendees
  3. We need to take the results at face value; there’s no independent verification
  4. The sample size is  95 respondents in this case
  5. Most respondents are likely to be enterprise-scale, which is particularly relevant to the results from the Australian Bureau of Statistics 2015 survey

    That is interesting. Every large Australian enterprise I’ve talked to uses the public cloud in multiple deployments, and I’m surprised at the large number that said otherwise in your survey.

    I wonder if some bias is introduced by the ‘private & hybrid cloud’ talk topic. Maybe higher proportion of customers who have security & privacy concerns with the public cloud.

      Thanks for the comment Tim.

      It’s a matter of relativity methinks … that was a very large number relative to what we see globally for enterprise usage right now.
      Moreover, relative to the ABS survey, it is verrrrrrrrrrrrry large.
