Actually a more complicated message queue, because it's on you to implement all the queueing logic. Then back it by a potentially non-durable data store (its very tricky to get redis durable and ha) with no monitoring?

All of this to avoid spinning up an SQS queue?

Isn't that a bit of an odd wording though. Of course if you only buy the horse without the cart you have to build the cart, making "your" solution more complicated. But you still bought the "simpler" solution i.e. the horse without a cart.

Complexity may be the wrong word, but what I mean is surface area for bugs you are responsible for.

I also question whether you really bought a horse in this analogy.
