Techfuse, a New Laptop, and How Microsoft Azure Helped Save the Day

24 04 2014

On Tuesday, April 22, I had the opportunity to speak at the Techfuse conference in Minneapolis. I was presenting a session on the differences between tabular and multidimensional models with a focus on the developer’s experience. My deck has tenTechFuse_logo  slides including title, references, and bio. The rest of the time is spent in Visual Studio building out equivalent models in using SSAS Tabular and SSAS Multidimensional.

The previous week, I was issued a new laptop from my company, a Dell 7440. This is a very nice machine and I had it all set for the presentation. About 11 AM (I was scheduled to speak at 1:15 PM) it occurred to me that I did not recall seeing a VGA port only HDMI. Next question, did the projectors at the convention center support HDMI? Answer, No. Now I had about an hour and a half to resolve this issue. Simple, I decided to head downtown and get the convertor from Office Depot. This was about 8 blocks away. I could do that and get some exercise in.

I took off at about 11:30. First, I stopped at Target, it was closer. No luck. So on to Office Depot. Keep in mind that Office Depot sells laptops like mine with only HDMI support and it stands to reason that they would have the converter. No such luck. I was able to get the HDMI converted to DVI, but that would not help as I later found out. They directed me to Radio Shack where I promptly picked up a DVI – VGA converter. Now I have three pieces that when strung together should support my needs. I headed back to the convention center and arrived with 30 minutes to spare. Working with the AV guy, we got it all plugged in only to still have it not work. Turns out you need a convertor to convert the digital signal to analog for use in the older projectors. Now what?

The moderator for my room offered me her laptop to use for the presentation. Which was AWESOME! So now I have a way to give the presentation, all ten slides. However, she did not have Visual Studio with SSDT for BI and SQL Server installed. Which was fine, because I didn’t expect her to.

Here is where Azure comes in. I had created a VM with SQL Server Tabular installed along with Visual Studio 2012 and the SQL Server Data Tools for BI. So, I firedth9CGBMYN6 up the VM right before I gave the presentation. I warned the crowd about what had happened and decided to push the demos to the end of the presentation so everyone could leave if nothing worked and all the material could be covered.

I was able to get into the VM, fire up Visual Studio. Since the demo was a live build of a tabular model and multidimensional model, I used a database I had created in SQL Azure as the data source and we built it the models live. Granted we were not able to do a complete multidimensional model because the database was not formatted as star schema, but it helped highlight the difference between what needs to be done prior to development. Overall it went very well (I think, surveys are forthcoming…). At the end of the day, without the work I had been doing in Azure I would not have been able to demo and it would have been a very short presentation.

Some lessons learned -

  • Be sure to have what you need to support presenting in a variety of scenarios. I should have made sure to have a converter prior to the conference as most convention centers and other facilities haven’t upgraded their projectors yet.
  • I will likely set up Azure VMs to support more demos. Just in case. It is always good to have a backup plan though a wireless connection would have painful to do that on.
  • Roll with it. Don’t give up, try to make the best of a bad situation. People understand things don’t always go perfectly. At the end of the day, I came to talk about multidimensional and tabular model development. I could have opened the floor up for discussion and did Q&A. Make the most of every situation.

Great presentation, I was thrilled that you ended up using Azure. It was good that you didn’t give up!

Thanks Joe. I am glad you enjoyed it. Maybe Azure should be a permanent part of that presentation…
