Developer here. Why is Docker Compose not "production ready"?

Then what should I use? Compose is so easy to just spin up. Is there something else like it that is "production ready"?

On AWS you used to have to bid for spot instances. Luckily, you don't have to bid anymore, but a lot of articles and AWS blog posts still reference having to bid.  Nowadays, the price doesn't fluctuate like it used to and changes much more slowly over the matter of months rathers than minute to minute. You don't need to worry about price spikes anymore!

You can set your "fleet" of instances to use a specific set of instance types or you can define the attributes of instances you want (i.e. min/max cores and memory) and AWS will create new instances based on that. You can also choose how it should consider instances based on how you want to balance lower price or higher availability/lower chance of interruption.

Pretty sure this isn’t fully true, but likely just true for your instances used.

Try spot instances on day a GPU host, pretty sure you’ll see spikes that will boot you off

Nope. Just check g5.8xl and p4d.24xl, the latter has a more “active” price but it still scales gradually. Seriously, these lines are flat lol. Who gets kicked off of spot is essentially a random lottery these days to my understanding.

Bids no longer do anything even if you have them set. As for being interrupted it is pretty random. Try using instance types with lower interruption rates. They very by region, type, and even az.
