It can be hard to get a perspective on how companies are developing their edge data centers. Reading through the websites and listening to sales pitches talk about the current offering explains the current, but rarely provides a perspective.
One way to get a perspective is to look at what has been presented in the past. Thanks to Youtube it can be easy to find the history.
Here is one example from Dell's data center group.
Here is a video from 2017 with Ty Schmitt and Mark Bailey discussing their edge solution.
Now shift to 2018 and here is Mark with another video.
If you are looking at an edge solution check out the youtube videos from the edge data center team and watch what they have been saying over the years. These videos can provide a perspective that the website and sales person neglect to explain.
