If you use life cycle management and data streams (which AWS doesn't have), you'd be able to control the sizes of your hot indices (i.e. the ones you write to). Basically keeping your hot indices small helps keeping things fast. If you have issues with app writes spiking, I'd use some queuing solution in between. Plenty of solutions for that. The rest is just a matter of configuring things right in terms of number of shards and setting up properly. Basically, you get what you pay for in the end.
