    Nice piece. It illustrates some of my misgivings about similar services. It’s heartening to see they seem to offer more tools to contain costs now than they used to.

    Hi, I’m Troy Hunt, I write this blog, create courses for Pluralsight and am a Microsoft Regional Director and MVP who travels the world speaking at events and training technology professionals

    The service he provides is quite good for the world in general. This might seem like the time to see if his employer could offer some retroactive relief on that sudden cost spike. Perhaps as a sponsorship for the service that undoubtedly helps their customers.

      I agree that it would be nice if we could pay for this but, somewhat confusingly, he is not actually a Microsoft employee. A Microsoft Regional Director is an external person who is endorsed by, but not paid by, Microsoft.

        Wow. That has been such a common title at places I’ve worked, it didn’t even occur to me it might be something else here.

          I can’t believe I’m still finding new ways in which Microsoft is literally the worst at naming things. Yikes.

          Usually if you ask customer support they’ll refund you, especially if there’s a sudden jump like this. I’ve seen much larger bills reversed.

          RE: the size of the data, HTTP CDNs have file size limits, it sucks to find out like this though. I think AWS CloudFront’s limit is 20 GB. Does Azure Blob Storage support requester pays? https://docs.aws.amazon.com/AmazonS3/latest/userguide/RequesterPaysBuckets.html. Unfortunately this general idea prevents anonymous (unauthenticated) access to the data.

          RE: cloud costs, big business risk! I’m continually disappointed that no cloud offers a “hit this cost then email me three times and disable this thing for the month”. We need stock trading “stop orders” for the cloud.

          I work for AWS, my opinions are my own not my employer’s.

            Azure does support this though. The cost alerts (like in the linked post) as well as hard spending limits. Or did you mean something else?

            1. 1

              Thank you! I did not know Azure supported spending limits. https://docs.microsoft.com/en-us/azure/cost-management-billing/manage/spending-limit

                Yeah, except now that I read about it, I think it’s not as general purpose as I thought. It looks tied to subscriptions that have monthly credits, which is how I became aware of it.

              I have cloudwatch alerts setup at different bill levels and as they come in make sure they match what they should be at that point in the month. I’m sure you could link SNS to something that started shutting things down. A regular task I perform is the cost analyzer–I have a budget to maintain.

              Alicloud has rate limiters on the device networking interface at least, I forget if you can just limit the data transfer entirely.

              I get wanting to be helpful, but, yikes–you’ve already got a torrent, if people really want this list let them pay their own way a little bit…

              1. 1

                So I guess they don’t bother to have a spending limit that prevent those kind of usage based billing? Or, maybe it’s time to switch to hosting that doesn’t bill by the traffic usage. I’ve been using about 20~90TB per month, on a $5 instance.
