How to present technical presentation with huge amount of information?

Question

I was invited to one of the biggest QA events (expected more than 400+ professionals) in my country with topic about performance testing.The information I would like to cover is:* Install two docker images (Grafana and InfluxDB) and configure them to communicate to each other;* Configure both of them (Grafana needs some time for setting up, InfluxDB will be quick);* Create a jMeter test (with all the explanations of how and why) and connect it to InfluxDB;* Configure Grafana to process and visualize the information;* Rework the test case to generate dashboard report (new in version 4.0).I have 30 minutes in total with following scheme - 30 minutes without questions from the public, 25 minutes with 5 minutes questions from the public and 20 minutes with 10 minutes questions.Public will be very heterogeneous containing junior/mid/senior/TL QA's and others (as DevOps, HR's, etc).**The problem**As you can see the huge amount of information that I need to pass to the public and the work I need to do.**Possible solutions:*** Create presentation containing screenshots of all steps that I do previously, no demo;* Same as previous, but run the tests live and analyze the results. Everything will be ready in advance;* Do a live demo.**What I'll not do**I went to enough events to know that reading from the slides, stuttering or uber boring academic mumbling type of lectures are the thing I would not like to give the persons who come to listen me.In most of my previous lectures I do it with few slides and mostly freestyle, but this one is different._Do you ever had such an experience and what would you prefer if you were in my place?_**Note**I have previous experience of lecturing (including academic) and I have good background of the stuff I would present.

How you present technical information in a presentation depends largely on the audience who will be receiving the information. Consider the level of expertise of the audience. You do not want to speak at such a high level that the audience looses attention. However, you also do not want to talk to people in a manner that inadvertently conveys you do not think they are very bright. If demonstrations help to better explain your topic, you should definitely include them.

Understand the culture of the audience. If connecting to people and being engaging is important to the audience, you need to be interactive.

Hope this helps.
