Agreed the article is unclear. My understanding is they’re using unused capacity on servers that are already performing other tasks. So they’re not really creating a spot market for unutilized servers, so much as for unutilized capacity on the severs they’re already using.

For example if one of their servers is using 50% CPU, they can fill the remaining 50% with video encoding tasks.

But obviously I don’t know any better than you. That’s just my takeaway from the vaguely worded article.

The article says they have a lot of reserved instances which at some point is not fully used.

So if you have 50 cpu hours reserved capacity per hour and during parts of the day you're using only 10h, they can allocate the remaining 40h which they reserved and paid upfront for encoding.
