Considering I spend $5 a month on my digitalocean droplet that runs docker 1.11 and a bunch of containers (nothing consequential though), and Gondor wants $100 for their entry-level "dev" tier...
Of course. But you may also correctly presume that I'll question why this would cost US$100/m for a "dev" offering. Considering what I can get for that from the other incumbents.
Some more background info here regarding Kel and it's relation to Gondor by Brian Rosner, the main dev of both Gondor and Kel as far as I can tell: https://brosner.com/blog/2016/05/05/kel/
